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…
LECX: a cubesat experiment to detect and localize cosmic explosions in hard X rays
J. Braga, O. S. C. Durao, M. Castro +8
With the advent of the nanosat/cubesat revolution, new opportunities have appeared to develop and launch small (\ts 1000 cm), low-cost (\ts US$ 1M) experiments in…
