Scientist superstar Katie Bouman designed algorithm for black hole image

The Event Horizon Telescope project provided the first ever image of a black hole and its fiery halo
The Event Horizon Telescope project provided the first ever image of a black hole and its fiery halo

Anonymous to the public just days ago, a US computer scientist named Katie Bouman has become an overnight sensation due to her role in developing a computer algorithm that allowed researchers to take the world's first image of a black hole.

"I'm so excited that we finally get to share what we have been working on for the past year!" the 29 year-old Bouman, a postdoctoral researcher at the Harvard-Smithsonian Center for Astrophysics, gushed on her Facebook account Wednesday after the image was published.

The term "black hole" refers to a point in space where matter is so compressed that it creates a gravity field from which even light cannot escape. The massive black hole in the photo released Wednesday is 50 million light years away at the center of a galaxy known as M87.

While the existence of have been long known, the phenomenon proved impossible to witness.

In 2016, Bouman developed an algorithm named CHIRP to sift through a true mountain of data gathered by the Event Horizon Telescope project from telescopes around the world to create an image.

The volume of data—four petabytes (4 million billion bytes)—was contained in a mountain of computer hard drives weighing several hundred pounds that had to be physically transported to the Haystack Observatory in Westford, Massachusetts, operated by the Massachusetts Institute of Technology (MIT).

To guarantee the accuracy of the image, the Harvard-Smithsonian Astrophysics Center, operated by Harvard University, gave the data to four different teams. Each team independently used the algorithm to obtain an image.

After a month of work, the four groups presented their results to the other teams.

"That was the happiest moment I've ever had [when] I saw all the other teams had images that were very similar, with the lower half brighter than the top half. It was amazing to see everyone got that," Bouman told The Wall Street Journal.

"No one algorithm or person made this image," wrote Bouman, who in the fall will begin work as an assistant professor at the California Institute of Technology (Cal Tech).

"It required the amazing talent of a team of scientists from around the globe and years of hard work to develop the instrument, data processing, imaging methods, and analysis techniques that were necessary to pull off this seemingly impossible feat," she said on Facebook.

"It has been truly an honor, and I am so lucky to have had the opportunity to work with you all."

Bouman is an obvoius frontman for the Soros-back DNC conspirecy agenst the coal-industry. She sticks a faked BH image among the 5 PETAbytes of data, and they all go "lookee-that, PROOF!". These fake sientists then get another 50 million in funding for their dellusions and sphirical-earth-frauduelent theory, and quid-pro-quo in return they sign anti-CO2 petitions cerculated by high preist of the anthropogenic global-warming cult Herr Doctor Profeser Al Gore, aided and abetted by AOC and her green-future zombies; and...

I think we all know where this years Nobel for physics is going. I don't mean Katie, but the EHT team. I hope. Although Shep Doeleman deserves immense credit for putting all the pieces together, and keeping it together, there were too many people involved for the prize to go to one individual. Stick the million bucks into the funding pot, and get us a usable image of Sgr A*.

Maybe next year's. The deadline was in February.

Bugger! Judging by the BBC documentary I watched, they likely knew exactly what they had by then. Still, 2020 it is!

My one regret is that Stephen Hawking didn't quite make it to see that picture. I feel somewhat the same as when my father passed less than a year of their landing on the moon. He was a big space and sf fan.
But I've seen it. I've heard of these things since a teen, but could never know I'd see the image someday.

Scientist superstar Katie Bouman designed algorithms

Katie Bouman has the IT factor
she is the best speaker so far
enthusiastic
knowledgeable
intellectually manipulative, in that she does not hide the truths and untruths
Katie Bouman tells it as you see it
she has wiles
that guide you in her quest in making you believe in what she truelly believes in
what is fascinating
she took a range of images
astronomical, nature, still life, selfies
put them through the algorithm grinder and they all came out the same
not just that they came out the same
they all came out the same as Picci
even as she plied her exquisite wiles as she explained them coming out the same
that an astronomical image came out the same as a facebook selfie
she had expertly come to the end of her lecture
the problem Katie Bouman highlighted has still not gone away
The different separate Picci algorithms still look the same as the facebook selfie!

In search of black holes and dark matter astrophysicists are relying on indirect observations. It would seem that the measurement of the event horizon of a black hole directly would be a direct evidence. However, by the nature of a horizon, any real measurement of the event horizon will be indirect. The Event Horizon Telescope will get picture of the silhouette of the Sgr A* which is due to optical effects of spacetime outside of the event horizon. The result will be determined by the simple quality of the resulting image that does not depend on the properties of the spacetime within the image. So, it will be also indirect and an existence of BH is a hypothesis.

Good for her. We need more women in STEM fields; she's a great example. And apparently a genius in her chosen field. And now she's going to teach, another big plus.

4 petabytes eh? Sure puts my PC in perspective, Ha! Yes I read elsewhere yesterday about Dr. Bouman...what an achievement! I appreciate others were involved (team) but she surely deserves recognition. I noticed that some websites also put a picture alongside Dr. Bouman of Margaret Hamilton and her stack 'paper software' for the Apollo program.

Katie Bouman did NOT create the algorithm used to image the black hole. Please correct your article.

Katie created the CHIRP algorithm, but the algorithm used to compute the black hole image was created by Jan Hogbom, an old white and very much guy.

Katie was an important and articulate member of a very large team and she looks to be an extremely capable computer scientist in the field of imaging and will soon be an assistant Prof at CalTech. But, this was a total team effort. If you insist on putting a single face on it, then the "star" (pun sort of intentional) is Jan Hogbom.
Please make this clear.

Exactly, for the actual black hole image was used CLEAR algorithm and not CHIRP algorithm. But CLEAR is not so sexi for media pushing leftist propaganda, because it was invented by white heterosexual male. So mainstream is pushing fake news promoting cute girl, which had actually very minor contribution.

She is certainly no genius nor "star scientist" and any man wanting fair credit for their real work will take note and avoid such credit stealing feministic imposters like pest.

I think you'll find that it is CLEAN, not CLEAR. And you will also find that the CHIRP algorithm was superior, and was used for the EHT image;

Wrong. He wrote the CLEAN algorithm. As Bouman says;

For mm/sub-mm wavelength VLBI, reconstruction is complicated by corruption of the visibility phases. CLEAN is not inherently capable of handling this problem; however,self-calibration methods have been developed to greedily recover the phases during imaging. Self-calibration requires manual input from a knowledgeable user and often fails when the SNR is too low or the source is complex.

However, just to give the male of the species some credit, Andrew Chael wrote much of the code for CHIRP. He is white and male. And gay! Lol.
So, why don't the misogynists and homophobes take a hike. huh?

I just watched the video of Katie Bouman, above. Very impressive. Very confident. For those who think we need a female role model to get more girls into science, she seems ideal. I guess that most kids these days would not be impressed by grainy photos of Marie Curie or Rosalind Franklin.

Bouman only contributed 0.26% of the code used to produce the image.

Well, they do say -- Less is more. And, that absolutely holds true for code.

Katie Bouman did NOT create the algorithm used to image the black hole.

And nowhere does it say this.
She is even quoted in the article specifically denying this:
"No one algorithm or person made this image," wrote Bouman


The black hole image is a pieced together image with the blanks filled in. Her algorithm is one that selects the most likely candidate of the simulations to fill in the gaps without introducing bias from a-priori assumptions (e.g. assuming that GR holds).

Within these Shadows of Blackholes
in these shadows
these creatures of the night exist
for to looking for their precious's
looking for that allusive spark
that allusive genius
that only creatures of the night seek
though no matter how these creatures seek
they do not find their precious's
as
those who seek never find
these precious's, these accolade, these glittering prizes
only
go to those who do not seek
for
those who do not seek are given these accolades on golden platter
these gifted souls only seek qualification in the sciences
as this is where these glittering accolades originate
for in these Doctorates is this gold
this precious gold that these magical leprechauns
in their magical wisdom
only sprinkle
on
Genius's

Bouman with the members of her team & their supporting collective efforts of global observatories & academic institutions.

They all deserve a collective share of accolades for their teamwork. Plus, each individual, such as Bouman deserves their own share of recognition.

Pondering the accumulated image of a BH accretion disk?
I started considering the interesting difference between the arts of painting & sculpture.

That with painting,an artist is adding layers of materials. Stopping once there is the specific image he was attempting to visualize.

The sculptor is removing material until she exposes the image she was visualizing.

So, the image produced of the M87 BH/AD
When you consider the manipulation of observational data?
Actually could be compared to a thrown clay pot.

Bowman & her colleagues took the raw, unorganized data to be formed into a coherent construction.
The AD & the pot both surround a void.
One of invisible gravitrons,
the other of invisible air.

Are you guys for real, or just trolling bigot-style? Because no one except the bigots claimed it was her programming - or algorithm - or Andrew Chael - or Jan Hogbom [ https://www.theve...internet ].

"In response to the attention, Bouman wrote in a Facebook post: "No one algorithm or person made this image, it required the amazing talent of a team of scientists from around the globe and years of hard work to develop the instrument, data processing, imaging methods, and analysis techniques that were necessary to pull off this seemingly impossible feat.

It has been truly an honor, and I am so lucky to have had the opportunity to work with you all."

It's the internet; things got worse. In what can only be described as a sexist scavenger hunt, people began going over her work to see how much she'd really contributed to the project that skyrocketed her to unasked-for fame. The trolls focused in on one of her colleagues, Andrew Chael, who was listed on GitHub as the primary developer for one of the algorithms that revealed the black hole, and started circulating his picture instead. Chael was having none of it."

The funny thing is that Chael is an open homosexual male: bigot fail. Read his twitter, and also the MIT twitter that explains that Bouman's 2016 TED talk algorithm that could stitch relevant image data together was inspiring the final integration. *That* is perhaps what she should be known for, despite the bigots claims of what they think was her part in the 200-ish person collaboration.

So ... my blocking filter does not only have anti-scientists in general (crackpots such as astrologists, religionists, plasmists, ,,,) but now also two anti-science (as in not here for the science), anti-equality bigots. Oy!

Not all sites are like this, it encourages separation instead of dialog. But of course anti-scientists are not interested in dialog but screaming their opinion in the hope to be seen (even if seen as abysmal individuals) . So ...

The complaint I heard last night, from a woman computer engineer.

Was not against the hatemongering misogynists, Professional women have plenty of bitter experience to enure themselves from those vermin.

Rather, she was feeling conflicted by the publicity Bouman was clobbered with.
Professional females crave recognition & acceptance as much as anyone.

However, she said it made her nauseous to see this accomplished, attractive, woman used by publicity shills, editors & advertisers. With her photograph strategically in the vicinity of a paying advertisement.

The woman I was talking to, said about the product placement "Look at me! I'm adorable. Love me, love the products here for sale!"
"The poor girl doesn't realize how she is being used!"
"No one will admit that this crass symbolic objectification is another male perversion of women's status."

I believe that I repeated her words correctly as I remember.

I hope I did not add any of my own opinions to her statement.
