The Canadian Astronomy Long Range Plan 2020-2030, a report on priorities and recommendations for Canadian astronomy over the next decade, has recommended that Canada support the National Radio Astronomy Observatory’s (NRAO) proposed Next Generation Very Large Array (ngVLA), saying the new facility will enable transformational science across many areas of astrophysics.
Comparing data from VLA sky surveys made some two decades apart revealed that the black hole-powered “engines” at the cores of some distant galaxies have launched new, superfast jets of material during the interval between the surveys.
New VLA images show how the crowded environment of a cluster of galaxies affects the individual galaxies, helping astronomers better understand some of the complex details of such an environment.
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...
