Small distant galaxies host supermassive black holes

(PhysOrg.com) -- Using the Hubble Space Telescope to probe the distant universe, astronomers have found supermassive black holes growing in surprisingly small galaxies. The findings suggest that central black holes formed ...

A cosmic exclamation point

(PhysOrg.com) -- VV 340, also known as Arp 302, provides a textbook example of colliding galaxies seen in the early stages of their interaction. The edge-on galaxy near the top of the image is VV 340 North and the face-on ...

Red-burning galaxies hold the key to galaxy evolution

A research team of astronomers from the University of Tokyo and the National Astronomical Society of Japan (NAOJ) has identified the location of red star-forming galaxies around a galaxy cluster situated four billion light ...

Galaxy Evolution Explorer finds dark energy repulsive

(PhysOrg.com) -- A five-year survey of 200,000 galaxies, stretching back seven billion years in cosmic time, has led to one of the best independent confirmations that dark energy is driving our universe apart at accelerating ...

Raging storms sweep away galactic gas

(PhysOrg.com) -- ESA's Herschel infrared space observatory has detected raging winds of molecular gas streaming away from galaxies. Suspected for years, these outflows may have the power to strip galaxies of gas and halt ...

Ultraviolet spotlight on plump stars in tiny galaxies

(PhysOrg.com) -- Astronomers using NASA's Galaxy Evolution Explorer may be closer to knowing why some of the most massive stellar explosions ever observed occur in the tiniest of galaxies.

Large galaxies stopped growing 7 billion years ago

(PhysOrg.com) -- Galaxies are thought to develop by the gravitational attraction between and merger of smaller 'sub-galaxies', a process that standard cosmological ideas suggest should be ongoing. But new data from a team ...

Surprise: Dwarf galaxy harbors supermassive black hole

(PhysOrg.com) -- The surprising discovery of a supermassive black hole in a small nearby galaxy has given astronomers a tantalizing look at how black holes and galaxies may have grown in the early history of the Universe. ...

Better understanding of carbon in comets with PSI research

(PhysOrg.com) -- Using a comet as a far-flung laboratory, a Planetary Science Institute researcher has shown that the ionization lifetime of carbon is much shorter than what is currently used in calculations by comet scientists. ...
