Astronomers have found two objects that, added to a strange object discovered in 2018, constitute a new class of cosmic explosions. The new type of explosion shares some characteristics with supernova explosions of massive stars and with the explosions that generate gamma-ray bursts (GRBs), but still has distinctive differences from each. The...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share very nearly the same plane, disks encircling wide binaries have orbital planes that are severely tilted. These systems...
Thankful Cromartie, a NRAO Grote Reber doctoral fellow at the University of Virginia’s Department of Astronomy, has received an Einstein Fellowship under the prestigious NASA Hubble Fellowship Program (NHFP). The program enables outstanding postdoctoral scientists to pursue independent astrophysical research. Each fellowship provides the awardee...
The team at CDL pushes the limits of engineering to help NRAO see the universe in new and powerful ways. Nestled among the hills of the University of Virginia campus are a couple of nondescript buildings. They are home to NRAO’s Central Development Laboratory (CDL). The buildings are easy to overlook, just as it is easy to overlook the work done...
