Using the Hard X-ray Modulation Telescope (HXMT) and the Neutron star Interior Composition Explorer (NICER), astronomers from China and India have observed two X-ray binaries known as GX 339−4 and EXO 1846−031. Results ...
Using NASA's Neil Gherels Swift Observatory, Indian astronomers have observed a blazar known as OJ 287. Results of the observational campaign, published May 25 on the arXiv pre-print server, shed more light on the spectral ...
An international team of astronomers reports the detection of a new, hot-dust-obscured galaxy (DOG). The galaxy, which received designation WISE J190445.04+485308.9, was found at a relatively low redshift of 0.415, which ...
Using the AstroSat spacecraft and the Neutron star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), Indian astronomers have observed an X-ray binary known as GX 349+2. Results of the observational ...
Researchers discovered only relatively recently that black hole jets emit X-rays, and how the jets accelerate particles to this high-energy state is still a mystery. Surprising new findings in Nature Astronomy appear to rule ...

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 ...
The James Webb Space Telescope (JWST) appears to be finding multiple galaxies that grew too massive too soon after the Big Bang, if the standard model of cosmology is to be believed.
