Evidence for 3XMM J185246.6+003317 as a massive magnetar with a low magnetic field
Rafael C. R. de Lima, Jonas P. Pereira, Jaziel G. Coelho +10
3XMM J185246.6+003317 is a transient magnetar located in the vicinity of the supernova remnant Kes\,79. So far, observations have only set upper limits to its surface magnetic fiel…
Breaking the degeneracy in magnetic cataclysmic variable X-ray spectral modeling using X-ray light curves
Diogo Belloni, Claudia V. Rodrigues, Matthias R. Schreiber +12
We present an analysis of mock X-ray spectra and light curves of magnetic cataclysmic variables using an upgraded version of the 3D CYCLOPS code. This 3D representation of the accr…
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…
