Galactic winds push researchers to probe galaxies at unprecedented scale
8/10/2017, 2:33:41 PMAfter using the Titan supercomputer at Oak Ridge National Laboratory to rule out a potential mechanism for galactic wind, astrophysicists are aiming to generate nearly a trillion-cell simulation of an entire galaxy, which would be the largest simulation ...
Why massive galaxies don't dance in crowds
8/10/2017, 7:49:34 AMScientists have discovered why heavyweight galaxies living in a dense crowd of galaxies tend to spin more slowly than their lighter neighbors. Contrary to earlier thinking, the spin rate of the galaxy is determined by its mass, rather than how crowded it...
Black holes pervade the universe, celestial census indicates
8/7/2017, 12:54:03 PMAfter conducting a cosmic inventory of sorts to calculate and categorize stellar-remnant black holes, astronomers have concluded that there are probably tens of millions of the enigmatic, dark objects in the Milky Way -- far more than expected.
Primordial black holes may have helped to forge heavy elements
8/4/2017, 10:18:16 AMAstronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis. But what about the heavier elements in the periodic chart, ...
Running out of gas: Gas loss puts breaks on stellar baby boom
8/2/2017, 5:33:12 AMUnderstanding the history of star formation in the Universe is a central theme in modern astronomy. Various observations have shown that the star formation activity has varied through the 13.8 billion-year history of the Universe. The stellar birthrate p...
Astronomers discover 'heavy metal' supernova rocking out
7/31/2017, 8:45:24 AMAn extraordinarily bright supernova occurred in a surprising location, astronomers have found. This 'heavy metal' supernova discovery challenges current ideas of how and where such super-charged supernovas occur. In the past decade, astronomers have disc...
Quasars may answer how starburst galaxies were extinguished
7/31/2017, 6:54:00 AMAstronomers have located quasars inside four dusty starburst galaxies. The observations suggest quasars may starve this type of galaxy of energy needed to form stars.
Glittering stars: Spiral galaxy NGC 4248
7/28/2017, 10:36:03 AMThis beautiful clump of glowing gas, dark dust and glittering stars is the spiral galaxy NGC 4248, located about 24 million light-years away in the constellation of Canes Venatici (The Hunting Dogs).
Astrophysicists map out the light energy contained within the Milky Way
7/27/2017, 7:13:03 PMFor the first time, a team of scientists has calculated the distribution of all light energy contained within the Milky Way, which will provide new insight into the make-up of our galaxy and how stars in spiral galaxies such as ours form.
Milky Way's origins are not what they seem
7/27/2017, 11:18:37 AMUp to half of the matter in our Milky Way galaxy may come from distant galaxies, astrophysicists have discovered in a first-of-its-kind analysis. As a result, each one of us may be made in part from extragalactic matter. Using supercomputer simulations, ...
