By analyzing archival data from the Suzaku X-ray satellite, astronomers have learned important information regarding thermal and non-thermal emission from the composite supernova remnant (SNR) designated MSH 15-56. Results ...
An international group of astronomers has detected an unusual nuclear transient in the nucleus of a weakly active galaxy. The new transient was identified by the OGLE-IV Transient Detection System and received designation ...
Precise measurement using a continent-wide collection of National Science Foundation (NSF) radio telescopes has revealed that a narrow jet of particles moving at nearly the speed of light broke out into interstellar space ...

Astronomers have detected transient rhythmic oscillations in the gamma-ray emission from the blazar Markarian 501. The discovery, reported in a paper published August 18 on the arXiv pre-print server could be helpful in improving ...
An international team of astronomers has conducted multi-wavelength photometric and spectropolarimetric observations of the quasar 3C 279, which revealed three different activity periods in this object. The finding is reported ...
Using very long baseline interferometry (VLBI), astronomers have investigated the magnetic field topology of the blazar 3C 279, uncovering the presence of multiple gamma-ray emission regions in this source. The discovery ...
A team of researchers from the U.S., New Zealand, Australia and Germany has found evidence suggesting that a type of star formation near the center of the Milky Way is responsible for large gamma ray emissions, not dark matter. ...
(Phys.org)—A team of astronomers led by Yogesh Maan of the Netherlands Institute for Radio Astronomy (ASTRON) has discovered radio emission from the gamma-ray pulsar known as J1732−3131. The study, presented in a paper ...
A terrifying few moments flying into the top of an active thunderstorm in a research aircraft has led to an unexpected discovery that could help explain the longstanding mystery of how lightning gets initiated inside a thunderstorm.
