Extra large galactic survey puts limits on ultralight particles
Physicists have long known that neutrinos are among the lightest and most evasive fundamental particles. Now a survey of the galaxies is helping to narrow down the neutrino mass even further. View News Article (2010-07-13)


Gas promises bumper black hole 'weigh-in'
A new way of measuring the mass of supermassive black holes could revolutionise our understanding of how they form and help to shape galaxies. View News Article (2013-01-31)


Astronomers discover dozens of mini-galaxies
A new survey made with the Anglo-Australian Telescope (AAT) has revealed dozens of previously unsuspected miniature galaxies in the nearby Fornax galaxy cluster. They belong to a class of galaxies dubbed "ultra-compact dwarfs" (UCDs), which was unknown before the same team of astronomers discovered 6 of them in the Fornax cluster in 2000. Now they say the UCDs outnumber the... View News Article (2004-03-25)


Compact galaxies in early Universe pack a big punch
Using the Near Infrared Camera and Multi-Object Spectrometer onboard of the Hubble NASA/ESA Hubble Space Telescope, astronomers have made observations of young, surprisingly compact galaxies, each only 5,000 light-years across, but weighing 200 billion times the mass of the Sun. View News Article (2008-04-30)


Radio Telescopes Reveal Unseen Galactic Cannibalism
Radio-telescope images have revealed previously-unseen galactic cannibalism -- a triggering event that leads to feeding frenzies by gigantic black holes at the cores of galaxies. Astronomers have long suspected that the extra-bright cores of spiral galaxies called Seyfert galaxies are powered by supermassive black holes consuming material. However, they could not see how the material is started... View News Article (2008-06-24)


The Milky Way's tiny but tough galactic neighbor
In the new ESO image, Barnard's Galaxy glows beneath a sea of foreground stars in the direction of the constellation of Sagittarius (the Archer). View News Article (2009-10-14)


Dwarf galaxies need dark matter too, U-M astronomers say
Stars in dwarf spheroidal galaxies behave in a way that suggests the galaxies are utterly dominated by dark matter, University of Michigan astronomers have found. View News Article (2007-10-25)


Milky Way Ransacks Nearby Dwarf Galaxies, Stripping All Traces of Star-Forming Gas
Astronomers using the National Science Foundation's Green Bank Telescope (GBT) in West Virginia, along with data from other large radio telescopes, have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame.  View News Article (2014-10-16)


Rain of giant gas clouds create active galactic nuclei
Galaxies like our own were built billions of years ago from a deluge of giant clouds of gas, some of which continue to rain down.  View News Article (2010-07-09)


Stars stop forming when big galaxies collide
Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters. View News Article (2008-10-08)
