Multiwavelength observations of Mkn 421 in a flaring state in Jan / Feb 2001 with HEGRA and RXTE
نویسنده
چکیده
The blazar type active galaxy Mkn 421 was observed during an active phase in January and February 2001 with the X-ray satellite RXTE and with the ground-based HEGRA system of TeV Cherenkov telescopes. Observations were coordinated to allow for simultaneous data taking. Both instruments observed time-dependent variations of the flux and the spectral shape in X-rays and TeV γ-rays. Variability and correlations in the TeV and X-ray bands are observed on timescales of hours.

Recent results obtained with the HEGRA system of imaging Cherenkov telescopes on the TeV emission of the Blazars Mkn 421 (z = 0.030), 1ES1959+650 (z = 0.047), and H1426+428 (z = 0.129) are reported. For Mkn 421, a close connection of the average flux level and spectral shape has been observed during the periods of increased activity in the years 2000 and 2001. Simultaneously taken data with the...

متن کاملOn the classification of flaring states of blazars
Aims. The time evolution of the electromagnetic emission from blazars, in particular high frequency peaked sources (HBLs), displays irregular activity not yet understood. In this work we report a methodology capable of characterizing the time behavior of these variable objects. Methods. The Maximum Likelihood Blocks (MLBs) is a model-independent estimator which sub-divides the light curve into ...

Since its commissioning in fall 1996, the stereoscopic system of Imaging Atmospheric Cherenkov Telescopes (IACTs) of HEGRA, with an energy flux sensitivity ν Fν at 1 TeV of 10−11 erg cm−2 s−1 for one hour of observation time, has been used to monitor the BL Lac object Mkn 421 on a regular basis. In this paper, we report detailed temporal and spectral information about the TeV characteristics of...

Pachmarhi Array of Čerenkov Telescopes (PACT), based on wavefront sampling technique, has been used for detecting TeV gamma rays from galactic and extra-galactic γ-ray sources. The Blazar, Mkn 421 was one such extragalactic source observed during the winter nights of 2000 and 2001. We have carried out a preliminary analysis of the data taken during the nights of January, 2000 and 2001. Results ...
