Active galactic nucleus in NGC 2992 explored by researchers
Researchers from the U.S. Naval Observatory and elsewhere have performed simultaneous observations of an active galactic nucleus (AGN) in the galaxy NGC 2992 using the Very Long Baseline Array (VLBA) and NASA's Swift spacecraft. ...
Quasars as the new cosmic standard candles
In 1929, Edwin Hubble published observations that galaxies' distances and velocities are correlated, with the distances determined using their Cepheid stars. Harvard astronomer Henrietta Swan Leavitt had discovered that a ...

Study investigates X-ray emission from the galaxy NGC 3894
Using NASA's Chandra spacecraft, astronomers have inspected X-ray emission from the center of a young radio galaxy known as NGC 3894. Results of this study, presented in a paper published June 24 on the arXiv pre-print server, ...
Observations inspect radio emission from two magnetars
Using the Australia Telescope Compact Array (ATCA) and the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have conducted a study of two magnetars known as PSR J1622−4950 and 1E 1547.0−5408. Results of ...
Two new outbursts detected from the magnetar 1E 1048.1−5937
Using NASA's Neil Gehrels Swift Observatory, astronomers have identified two new outbursts from the magnetar 1E 1048.1−5937. The newly detected events could shed more light on the nature of this source. The finding is detailed ...
Astronomers probe the nature of a peculiar pulsar wind nebula
Using ESA's XMM-Newton spacecraft, astronomers have investigated the nature of a peculiar pulsar wind nebula (PWN) in the supernova remnant (SNR) CTB 87. Results of the study, presented in a paper published November 26, shed ...
