Using NASA's Swift observatory and ESA's XMM-Newton satellite, Indian astronomers have inspected a prominent high synchrotron peaked blazar known as 1ES 1959+650. Results of the study, published May 5 on the arXiv pre-print ...
An international team of astronomers has conducted a long-term multiwavelength monitoring campaign of a nearby narrow-line Seyfert 1 galaxy known as SDSS J164100.10+345452.7. Results of the observations, published March 9 ...
Using the Very Large Telescope (VLT) of the European southern Observatory (ESO), an international team of astronomers has observed a tidal disruption event known as AT 2022cmc. Results of the observational campaign, presented ...
Using the Very Long Baseline Array (VLBA), astronomers have performed high-resolution observations of the blazar PKS 1749+096. Results of this observational campaign, presented in a paper published October 23 on arXiv.org, ...
Using the Very Long Baseline Interferometry (VLBI) technique, astronomers have probed the parsec-scale jet of a neutrino-emitting blazar known as TXS 0506+056. Results of the new study, presented May 1 on arXiv.org, shed ...
Using Russia's Spektr-R space telescope (also known as RadioAstron), astronomers have conducted high-resolution observations of the blazar S5 0716+71. The results of these observations, presented in a paper published February ...
Researchers have identified a new blazar-like narrow-line Seyfert 1 galaxy that emits gamma-ray radiation. The new galaxy, designated SDSS J211852.96−073227.5, could offer insights into formation and evolution of jets of ...
Through first-of-their-kind supercomputer simulations, researchers, including a Northwestern University professor, have gained new insight into one of the most mysterious phenomena in modern astronomy: the behavior of relativistic ...
