ALMA early science result reveals starving galaxies

(PhysOrg.com) -- Astronomers using the partially completed ALMA observatory have found compelling evidence for how star-forming galaxies evolve into 'red and dead' elliptical galaxies, catching a large group of galaxies right ...

Strange new 'species' of ultra-red galaxy discovered

In the distant reaches of the universe, almost 13 billion light-years from Earth, a strange species of galaxy lay hidden. Cloaked in dust and dimmed by the intervening distance, even the Hubble Space Telescope couldn't spy ...

Astronomers pin down galaxy collision rate

(PhysOrg.com) -- A new analysis of images from the Hubble Space Telescope combined with supercomputer simulations of galaxy collisions has cleared up years of confusion about the rate at which smaller galaxies merge to form ...

Close encounters of the galactic kind

(PhysOrg.com) -- Astronomers have used a large survey to test a prediction that close encounters between galaxies can trigger the rapid growth of supermassive black holes. Key to this work was Chandra's unique ability to ...

Is M85 missing a black hole?

The conventional wisdom of galaxies is that they should have a central massive black hole (CMBH). The presence of such objects has been confirmed in our own galaxy as well as numerous other galaxies, including the Andromeda ...

Distant galaxies reveal the clearing of the cosmic fog

(PhysOrg.com) -- Scientists have used ESO's Very Large Telescope to probe the early Universe at several different times as it was becoming transparent to ultraviolet light. This brief but dramatic phase in cosmic history ...

Stellar winds

(PhysOrg.com) -- The Sun, glowing with a surface temperature of about 5500 degrees Celsius, warms the Earth with its salutary light. Meanwhile the Sun's hot outer layer (the corona), with its temperature of over a million ...

Cosmic weight watching reveals black hole-galaxy history

(PhysOrg.com) -- Using state-of-the-art technology and sophisticated data analysis tools, a team of astronomers from the Max Planck Institute for Astronomy has developed a new and powerful technique to directly determine ...
