Using the LOw Frequency ARray (LOFAR), European astronomers have carried out radio observations of a low-mass galaxy cluster known as PSZ2G145.92-12.53, dubbed the Ant Cluster. In result, they identified a radio halo—a ...
It is generally believed that double-peaked broad emission lines originate from an elliptical disk. Appearance or disappearance of the broad Balmer emission lines correspond to type 1 and type 2 active galactic nuclei (AGNs), ...

Using the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), astronomers have discovered an unusual binary system. The newly found binary, designated LAMOST J0140355+392651 (or J0140 for short), consists ...
In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), ...
