X-Ray Emission of Cataclysmic Variables Observed by Integral

Paltani, S.; Gális, R.; Eckert, D. +2 more

Magnetic cataclysmic variables represent a significant fraction of all INTEGRAL detections in hard X-rays and soft gamma rays. Our deep survey of all known intermediate polars revealed five new sources, previously undetected by this mission. Our analysis, based on all available observational data from the IBIS and JEM-X instruments, has shown that…

Global Characteristics of Gamma-Ray Bursts Observed with INTEGRAL

McGlynn, S.; McBreen, S.; Foley, S. +5 more

The gamma-ray instruments on board INTEGRAL have detected and localized 62 gamma-ray bursts (GRBs) to date. The peak flux distribution of these bursts shows that INTEGRAL detects proportionally more weak GRBs than Swift because of its higher sensitivity in a smaller field of view. Spectral lags, i.e., the time delay in the arrival of low-energy ga…

Blazars with Integral

Pian, E.; Hudec, R.; Blažek, M. +1 more

The analysis of the INTEGRAL data for blazars, a specific class of the active galactic nuclei, is described. These objects are promising objects for observations by INTEGRAL, especially during their active states. A strategy for their future investigation is proposed and discussed.

Czech Participation in Integral

Hudec, R.; Blažek, M.; Kocka, M. +1 more

The INTEGRAL gamma-ray observatory, launched in October of 2002, is the first astrophysical mission of the European Space Agency with the Czech participation. Here we present and discuss the results of our investigations of cataclysmic variables, blazars, X-ray sources and GRBs obtained during the first six years of the mission.

Web-Based Approach to the Integral Data

Münz, Filip; Kocka, Matúš

Our extensive exploration of the INTEGRAL data in gamma and X-ray domains had two principal aims: to cover as many sources of chosen categories as possible (with sufficient upper limits of their fluxes) and to check for their eventual variability. This means treating a large number of time-resolved results that can be most easily approached using …
