Astronomers have carried out an observational campaign to study the extreme variability of the active galactic nucleus (AGN) SDSS J2232−0806, nicknamed the Big Dipper. Results of these observations, described in a paper ...
Japanese astronomers report the identification of a new ultra-luminous infrared galaxy (ULIRG) as part of the search for far-infrared-bright but optically faint objects. The newly detected ULIRG, designated AKARI-FIS-V2 J0916248+073034, ...
Astronomers have found a new eclipsing binary system by analyzing archival survey data and conducting follow-up radial velocity measurements. The newly found binary, designated SDSSJ1156-0207, is composed of two M-dwarf stars ...
By analyzing the light of hundreds of thousands of celestial objects, Johns Hopkins astronomers from the Sloan Digital Sky Survey have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling ...
