Supermassive black holes put a brake on stellar births

Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state of the art simulations to back up results from a large sky survey, the ...

Hubble spots double quasars in merging galaxies

NASA's Hubble Space Telescope is "seeing double." Peering back 10 billion years into the universe's past, Hubble astronomers found a pair of quasars that are so close to each other they look like a single object in ground-based ...

The Milky Way does the wave

In results announced this week at the 237th Meeting of the American Astronomical Society, scientists from the Sloan Digital Sky survey present the most detailed look yet at the warp of our own galaxy.

Graduate student's BADASS code has astronomical benefits

An astro-statistics course University of California, Riverside, graduate student Remington O. Sexton took three years ago taught him techniques that led him to develop free, open-source code benefiting astronomers everywhere.

New extremely variable quasar discovered

By analyzing data from astronomical surveys, Japanese astronomers have detected a new, extremely variable quasi-stellar object (QSO), or quasar. The newly found object, designated SDSS J125809.31+351943.0, brightened in optical ...

The recipe for powerful quasar jets

Some supermassive black holes launch powerful beams of material, or jets, while others do not. Astronomers may now have identified why.
