An international team of astronomers has investigated an extremely luminous infrared galaxy known as WISEJ090924.01+000211.1 (or WISEJ0909+0002 for short) as part of the eROSITA final equatorial depth survey (eFEDS). Results ...
Using NASA's Swift space telescope and NICER instrument aboard the International Space Station (ISS), astronomers have investigated the properties of an ultra-luminous X-ray pulsar known as NGC 300 ULX1. Results of this study, ...
In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material. These two monsters should be the most luminous X-ray sources in sight, but a new study using ...
