Markarian 421’s Unusual Satellite Galaxy
We present Hubble Space Telescope (HST) imagery and photometry of the active galaxy Markarian 421 and its companion galaxy 14 arcsec to the ENE. The HST images indicate that the companion is a morphological spiral rather than elliptical as previous ground–based imaging has concluded. The companion has a bright, compact nucleus, appearing unresolved in the HST images. This is suggestive of Seyfe...
متن کاملXMM − Newton observations of Markarian 421 ?
The BL Lac object Mrk 421 was observed on May 25, 2000 during the XMM−Newton Cal/PV phase. The high throughput of the X-ray telescopes and the spectral capabilities of the instruments allow an uninterrupted temporal and spectral study of the source with unprecedented time resolution. Mrk 421 was found at a relatively high state with a 2−6 keV flux of (1.3−1.9)×10−10 erg cm−2 s−1. The observed i...
متن کاملX-ray flaring activity of Markarian 421
We report results from a systematic search for X-ray flares from Mrk 421, using archival data from the Rossi X-Ray Timing Explorer (RXTE) satellite. The flares are clearly seen over a wide range of timescales. The quasicontinuous coverage of the source with the All-SkyMonitor (ASM) reveals frequent occurrence of major flares that last for months. On a few occasions, the source was intensively m...
متن کاملX-ray flares from Markarian 501
Motivated by the recent discovery of a hierarchical X-ray flaring phenomenon in Mrk 421, we conducted a systematic search for X-ray flares from Mrk 501, another well-known TeV blazar, by making use of the rich RXTE archival database. We detected flares over a wide range of timescales, from months down to minutes, as in the case of Mrk 421. However, the flares do not seem to occur nearly as freq...
متن کاملTeV OBSERVATIONS OF THE VARIABILITY AND SPECTRUM OF MARKARIAN 421
Markarian 421 was the first extragalactic source to be detected with high statistical certainty at TeV energies. The Whipple Observatory gamma-ray telescope has been used to observe the Active Galactic Nucleus, Markarian 421 in 1996 and 1997. The rapid variability observed in TeV gamma rays in previous years is confirmed. Doubling times as short as 15 minutes are reported with flux levels reach...
