Evolution of the Synchrotron Spectrum in Mrk421 during the 1998 Campaign
Chiharu Tanihata, Tadayuki Takahashi, Jun Kataoka +1
The uninterrupted 7-day ASCA observations of the TeV blazar Mrk421 in 1998 have clearly revealed that X-ray flares occur repeatedly. In this paper, we present the results of the ti…
Implications of Variability Patterns observed in TeV Blazars on the Structure of the Inner Jet
Chiharu Tanihata, Tadayuki Takahashi, Jun Kataoka +1
The recent long look X-ray observations of TeV blazars have revealed many important new features concerning their time variability. In this paper, we suggest a physical interpretat…
RXTE Observations of 3C273 between 1996 and 2000:Variability Timescale and Jet Power
Jun Kataoka, Chiharu Tanihata, Nobuyuki Kawai +4
We present the results of a long-look monitoring of 3C273 with RXTE between 1996 and 2000. A total of 230 observations amounts to a net exposure of 845ksec, with this spectral and…
Five-year Monitorings of TeV Blazars with ASCA and RXTE
J. Kataoka, T. Takahashi, F. Takahara +8
We study the temporal/spectral variability of two extragalactic TeV sources, Mrk 421 and Mrk 501, based on 5-year observations with the ASCA and RXTE satellites. We found that the…
Characteristic X-ray Variability of TeV Blazars: Probing the Link between the Jet and the Central Engine
Jun Kataoka, Tadayuki Takahashi, Stefan J. Wagner +8
We have studied the rapid X-ray variability of three extragalactic TeV gamma-ray sources; Mrk 421, Mrk 501 and PKS 2155-304. Analyzing the X-ray light curves obtained from ASCA and…
Rapid Synchrotron Flares from BL Lacertae Detected by ASCA and RXTE
C. Tanihata, T. Takahashi, J. Kataoka +6
We report the variable X-ray emission from BL Lacertae detected in the ASCA ToO observation conducted during the EGRET and RXTE pointings, coincident with the 1997 July outburst. T…
