Using the Australia Telescope Compact Array (ATCA), an international team of astronomers has observed the population of submillimeter galaxies in a protocluster known as SPT 2349-56. As a result, they found a radio-loud active ...
An international team of astronomers has performed a comprehensive, multiwavelength study of a blazar known as 1ES 1218+304. Results of the research, presented in a paper published January 3 on the arXiv preprint server, ...
An international team of astronomers has performed a long-term multiwavelength study of a distant gamma-ray emitting blazar known as 1ES 0647+250. Results of the research, published November 23 on arXiv.org, yield important ...
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 ...
Using ESA's XMM-Newton and NASA's Swift space telescopes, an international team of astronomers have observed a nearby galaxy known as NGC 55. They discovered a new transient ultraluminous X-ray source in this galaxy. The ...
Astronomers from the California Institute of Technology (Caltech) and elsewhere have observed an ultraluminous X-ray source known as NGC 925 ULX-3 using NASA's Swift and NuSTAR spacecraft, as well as ESA's XMM-Newton satellite. ...
An international team of astronomers reports the detection of a new luminous quasi-stellar object, or quasar. The newly found object, designated SMSS J114447.77-430859.3 (or J1144 for short) turns out to be the most luminous ...
By analyzing the data from ESA's XMM-Newton satellite, astronomers from the Astronomical Observatory of the Jagiellonian University in Kraków, Poland, and elsewhere, have investigated X-ray intraday variability of a nearby ...
By analyzing the data from four space observatories, European astronomers have presented a complete and thorough X-ray view of an active galactic nucleus in a nearby spiral galaxy known as NGC 4258. Results of the study, ...
By analyzing the historical light curve of blazar PKS 0405-385 from NASA's Fermi spacecraft, Chinese astronomers have detected quasi-periodic oscillation from this source. The discovery, presented in a paper published May ...
