Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope, astronomers have detected a bright, millisecond-duration radio burst from a galactic magnetar known as SGR 1935+2154. The discovery of such ...
Astronomers have used mysterious fast radio bursts to solve a decades-old mystery of "missing matter," long predicted to exist in the universe, but never before detected. The researchers have determined that all of the unaccounted ...

In a new study published April 23 on arXiv.org, Spanish astronomers have reported on an extreme blazar known as 2WHSP J073326.7+515354. Results of the research reveal the distance to this source and provide essential information ...
Astronomers have carried out very-long-baseline interferometric (VLBI) observations of the quasar IRAS F11119+3257 using the European VLBI Network (EVN). They found that the object has a high velocity two-sided jet, a finding ...
Using the Large Area Telescope (LAT) onboard NASA's Fermi spacecraft, astronomers have investigated a nearby radio galaxy known as NGC 3894. Results of the study, presented in a paper published March 3, confirm the galaxy's ...
