3C 371 is a BL Lac object [1] [2] located in the constellation Draco. With a redshift of 0.051, [2] this active galaxy is about 730 million light-years away. [3] 3C 371 is a well known object, first associated with the BL Lac class by Miller in 1975, [4] and …

Mar 26, 2024 · The goal of this study is evaluating the optical variability of 3C 371. Taking advantage of the remarkable cadence of \textit{TESS} data, we aim to characterize the intra-day variability (IDV) displayed by the source and identify its shortest variability timescale.

Dec 5, 2024 · Abstract: The BL Lac object 3C 371 is one of the targets that are regularly monitored by the Whole Earth Blazar Telescope (WEBT) Collaboration to study blazar variability on both short and long timescales. We aim to evaluate the long-term multiwavelength (MWL) behaviour of 3C 371, comparing it with the results derived for its optical emission ...

The compact extragalactic radio source, 3C 371, was observed with the X-ray detectors of the EXOSAT satellite for 19.5 hours in 2 observing periods separated by 18 days. This resulted in the discovery of X-ray variability of the source on time scales between 8 hours and about 25 minutes and the confirmation of earlier reports of variability on ...

Dec 27, 1999 · Abstract: We present the first space VLBI observations of 3C~371, carried out at a frequency of 4.8 GHz. The combination of the high resolution provided by the orbiting antenna Highly Advanced Laboratory for Communications and Astronomy (HALCA) and the high sensitivity of the VLBA allows imaging of the jet of 3C~371 with an angular resolution ...

The BL Lac object 3C 371 was observed by the Transiting Exoplanet Survey Satellite (TESS) for approximately a year, between July 2019 and July 2020, with an unmatched two-minute imaging cadence. In parallel, the Whole Earth Blazar Telescope (WEBT) Collaboration organized an extensive observing campaign, providing three years of continuous ...

High dynamic range VLA imaging reveals, for the first time, that the blazar 3C 371 exhibits very low surface brightness twin radio lobes. These lobes straddle the dominant compact core and have a projected extent of ~ 42h^-1^ kpc.

The N galaxy/BL Lacertae object 3C 371 was observed by EXOSAT on two occasions separated by 18 days in September 1984. The low-energy and medium-energy X-ray flux has varied on the time scale of years (in comparison with HEAO 1 and Einstein Observatory measurements), 18 days (between the authors' two observations), and 8 hr to about 25 minutes ...
