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 ...
Using various space telescopes, an international team of astronomers have observed a recently detected luminous quasar known as SMSS J114447.77-430859.3, or J1144 for short. Results of the observational campaign, available ...
Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner ...
