Using NASA's Wide-field Infrared Survey Explorer (WISE), astronomers from South Korea and China have detected a mid-infrared flare in an active spiral galaxy known as NGC 3786. The researchers assume that this peculiar flare ...
When astronomers use radio telescopes to gaze into the night sky, they typically see elliptical-shaped galaxies, with twin jets blasting from either side of their central supermassive black hole. But every once in a while—less ...

Using the Neutron Star Interior Composition Explorer (NICER), an international team of astronomers have detected a new accreting millisecond X-ray pulsar. The newfound pulsar, designated MAXI J1816–195, has a spin period ...
Black hole X-ray binaries (BHXB) comprise a stellar-mass black hole accreting gas from a companion star and emitting transient X-ray emission and compact radio jets.
