Astronomers from Switzerland and Germany have performed multiwavelength observations of a high-synchrotron-peaked blazar known as Mrk 421. Results of this observational campaign provide more insights into the variability ...
Using the Suzaku satellite, astronomers have examined a very high energy (VHE) blazar known as PKS 2155−304. They found that the source exhibits an X-ray intraday variability, which could improve the understanding of its ...
A recent study suggests the possible existence of 'stupendously large black holes' or SLABS, even larger than the supermassive black holes already observed in the centers of galaxies.

Using ESO's Very Large Telescope (VLT), astronomers have investigated ionized gas in the central regions of the Seyfert galaxy NGC 7130. In their study, they identified a complex multi-component outflow in this galaxy. The ...
Using the Karl G. Jansky Very Large Array (VLA) and the upgraded Giant Meter Radio Telescope (uGMRT), astronomers have conducted multi-wavelength observations of a galaxy merger remnant known as Mrk 212. Results of this observational ...
