Using data from space observatories and ground-based telescopes, astronomers have investigated variability of a blazar known as 3C 273. The new study, presented in a paper published July 6 on the arXiv pre-print server, sheds ...
Using three NASA space observatories, astronomers have conducted a multiwavelength study of emission from a blazar known as 1ES 1218+304. Results of the investigation, presented in a paper published June 29 on arXiv.org, ...
An international team of astronomers has performed a decade-long, multi-wavelength monitoring campaign of the blazar 1ES 1215+303. Results of this extensive study provide more insights into the nature of emission from this ...
An international team of astronomers has studied variable broadband emission of the gamma-ray blazar Markarian 501 during a period of its high X-ray activity. The research, published January 21 on the arXiv preprint server, ...
An international team of astronomers reports the detection of quasi-periodic variability in optical and gamma-ray light curves of two blazars, namely 3C 66A and B2 1633+38. The discovery could be helpful in advancing our ...
Italian astronomers have conducted multi-band observations of the high-redshift blazar S5 0836+710 during its period of high activity. The monitoring campaign resulted in the detection of two major gamma-ray flares from this ...
Astronomers from Italy and Spain have detected a new blazar by analyzing data from two astronomical surveys. The newly found object, designated DESJ014132.4-542749.9, turns out to be an extremely X-ray-weak blazar at high ...
Using very-long-baseline-interferometry (VLBI), an international team of astronomers has conducted a kinematic study of a jet of the blazar 4C+21.35. The research, presented in a paper published April 5 on the arXiv pre-print ...
Using Russia's Spektr-R space telescope (also known as RadioAstron), astronomers have conducted high-resolution observations of the blazar S5 0716+71. The results of these observations, presented in a paper published February ...
Using Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) telescopes, an international group of astronomers has detected a fast, very high-energy (VHE) flare from the blazar BL Lacertae. The finding is detailed in a paper ...
