Temperature Structure in the Perseus Cluster Core Observed with Hitomi
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +192
The present paper investigates the temperature structure of the X-ray emitting plasma in the core of the Perseus cluster using the 1.8--20.0 keV data obtained with the Soft X-ray S…
Glimpse of the highly obscured HMXB IGR J16318-4848 with Hitomi
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +191
We report a Hitomi observation of IGR J16318-4848, a high-mass X-ray binary system with an extremely strong absorption of N_H~10^{24} cm^{-2}. Previous X-ray studies revealed that…
Search for Thermal X-ray Features from the Crab nebula with Hitomi Soft X-ray Spectrometer
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +192
The Crab nebula originated from a core-collapse supernova (SN) explosion observed in 1054 A.D. When viewed as a supernova remnant (SNR), it has an anomalously low observed ejecta m…
The X-ray Flux Distribution of Sagittarius A* as Seen by Chandra
J. Neilsen, S. Markoff, M. A. Nowak +11
We present a statistical analysis of the X-ray flux distribution of Sgr A* from the Chandra X-ray Observatory's 3 Ms Sgr A* X-ray Visionary Project (XVP) in 2012. Our analysis indi…
First results of IBIS/ISGRI Cygnus X-3 monitoring during INTEGRAL PV phase
P. Goldoni, J. -M. Bonnet-Bidaud, M. Falanga +1
We report on preliminary results of IBIS/ISGRI serendipitous observations of Cygnus X-3 in the 15-100 keV energy range during the INTEGRAL Performance and Verification phase. This…
XMM-Newton observation of the bursting pulsar GRO J1744-28 in quiescence
F. Daigne, P. Goldoni, P. Ferrando +3
The XMM-Newton X-ray observatory performed a pointed observation of the bursting pulsar GRO J1744-28 in April 2001 for about 10 ks during a program devoted to the scan of the Galac…
GRANAT/SIGMA Observation of the Early Afterglow from GRB 920723 in Soft Gamma-Rays
R. A. Burenin, A. A. Vikhlinin, M. R. Gilfanov +13
We present a GRANAT/SIGMA observation of the soft gamma-ray afterglow immediately after GRB 920723. The main burst is very bright. After ~6 s, the burst light curve makes a smooth…
Two Distinct Modes In The Low (Hard) State Of Cyg X-1 And 1E1740-294
S. Kuznetsov, M. Gilfanov, E. Churazov +12
The entire dataset of the GRANAT/SIGMA observations of Cyg X-1 and 1E1740.7-294 in 1990-1994 was analyzed in order to search for correlations between primary observational characte…
