On the behavior of the black hole candidate 1E 1740.7-2942's corona based on long-term INTEGRAL database
Paulo Eduardo Stecchini, Jurandi Leão, Manuel Castro +1
One of the most straightforward ways to explain the hard X-ray spectra observed in X-ray binaries is to assume that comptonization of soft photons from the accretion disk is occurr…
Study of Blazar activity in 10 year Fermi-LAT data and implications for TeV neutrino expectations
J. R. Sacahui, A. V. Penacchioni, A. Marinelli +4
Blazars are the most active extragalactic gamma-ray sources. They show sporadic bursts of activity, lasting from hours to months. In this work we present a 10-year analysis of a sa…
A magnetic white-dwarf accretion model for the anomalous X-ray pulsar 4U 0142+61
Sarah V. Borges, Claudia V. Rodrigues, Jaziel G. Coelho +2
The quiescent emission of the anomalous X-ray pulsar (AXP) 4U 0142+61 extends over a broad range of energy, from radio up to hard X-rays. In particular, this object is unique among…
Broadband X-ray analysis of 1E 1740.7-2942: constraints on spin, inclination and a tentative black hole mass
Paulo E. Stecchini, Flavio D'Amico, Francisco Jablonski +2
1E 1740.7-2942 is one of the strongest hard X-ray emitters in the Galactic Centre region, believed to be a black hole in a high-mass X-ray binary system. Although extensively studi…
Tandem Swift and INTEGRAL Data to Revisit the Orbital and Superorbital Periods of 1E 1740.7-2942
Paulo Eduardo Stecchini, Manuel Castro, Francisco Jablonski +2
The black hole candidate 1E 1740.7-2942 is one of the strongest hard X-ray sources in the Galactic Center region. No counterparts in longer wavelengths have been identified for thi…
Comptonization in 1E 1740.7-2942 spectra from 2 to 200 keV
Manuel Castro, Taís Maiolino, Flavio D'Amico +3
Studies of the long-term spectral variations have been used to constrain the emission processes of black hole candidates. However, a common scenario which is able to explain the em…
