Sky survey reveals newborn jets in distant galaxies(图)     Sky survey  newborn jets  distant galaxies       font style='font-size:12px;'> 2020/12/11
Astronomers using data from the ongoing VLA Sky Survey have found distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material w...
ALMA sees most distant Milky Way look-alike(图)     ALMA;distant Milky;Way look-alike       font style='font-size:12px;'> 2020/8/21
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The results are...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted the light of a massive galaxy seen only 970 million years after the Big Bang. Called MAMBO-9, it's the most dista...
An NSF-supported team of astronomers found new evidence of the occurrence of a kilonova -- a cosmic explosion that creates massive amounts of gold and platinum -- that went unnoticed during initial ob...
VLA Reveals Distant Galaxy’s Magnetic Field(图)     VLA  Distant Galaxy  Magnetic Field       font style='font-size:12px;'> 2017/9/5
With the help of a gigantic cosmic lens, astronomers have measured the magnetic field of a galaxy nearly five billion light-years away. The achievement is giving them important new clues about a probl...
Gemini Tracks Distant Star Cluster with Adaptive Optics     Gemini  Distant Star Cluster  Adaptive Optics       font style='font-size:12px;'> 2017/7/20
We present a proper motion measurement for the halo globular cluster Pyxis, using HST/ACS data as the first epoch, and GeMS/GSAOI Adaptive Optics data as the second, separated by a baseline of ~ 5 yea...
ALMA investigates ‘DeeDee,’a distant,dim member of our solar system     ALMA  DeeDee  a distant  dim member  solar system       font style='font-size:12px;'> 2017/4/27
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have revealed extraordinary details about a recently discovered far-flung member of our solar system, the planetary body 2014...
A mysterious flash of X-rays has been discovered by NASA’s Chandra X-ray Observatory in the deepest X-ray image ever obtained. This source likely comes from some sort of destructive event, but it may ...
For decades, astronomers have found distant galaxies by detecting the characteristic way their gas absorbs light from a bright quasar in the background. But efforts to observe the light emitted by the...
Pushing the limits of the largest single-aperture millimeter telescope in the world, and coupling it with gravitational lensing, University of Massachusetts Amherst astronomer Alexandra Pope and colle...
UCLA astronomers have made the first accurate measurement of the abundance of oxygen in a distant galaxy. Oxygen, the third-most abundant chemical element in the universe, is created inside stars and ...
Supermassive black holes lurk at the center of every large galaxy. These cosmic behemoths can be millions to billions of times more massive than the Sun. Determining just how massive, however, has bee...
Distant supernova split four ways by gravitational lens(图)     Distant supernova  split  gravitational lens       font style='font-size:12px;'> 2015/3/18
Over the past several decades, astronomers have come to realize that the sky is filled with magnifying glasses that allow the study of very distant and faint objects barely visible with even the large...
Measuring star formation in local and distant galaxies     local  distant galaxies       font style='font-size:12px;'> 2014/12/23
I review measurements of star formation in nearby galaxies in the UV-to-FIR wavelength range, and discuss their impact on SFR determinations in intermediate and high redshift galaxy populations. Exist...
