Using the Imaging X-ray Polarimetry Explorer (IXPE), an international team of astronomers has conducted X-ray polarimetric observations of an accreting X-ray pulsar known as Vela X-1. Results of the observational campaign, ...
An international team of astronomers has conducted a long-term multi-frequency radio monitoring of a nearby blazar known as OJ 287. Results of the observational campaign, published February 22 on the pre-print server arXiv, ...
Using three space telescopes, Armenian astronomers have observed a flaring high-redshift blazar known as PKS 0537-286. Results of the observational campaign, presented February 15 on the pre-print server arXiv, deliver important ...
For the first time, researchers have recorded live and in atomic detail what happens to the material in an asteroid impact. The team of Falko Langenhorst from the University of Jena and Hanns-Peter Liermann from DESY simulated ...
