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…
Telescope performance and image simulations of the balloon-borne coded-mask protoMIRAX experiment
A. V. Penacchioni, J. Braga, M. A. Castro +1
In this work we present the results of imaging simulations performed with the help of the GEANT4 package for the protoMIRAX hard X-ray balloon experiment. The instrumental backgrou…
Flux and spectral variations of 1E1740.72942 over the years 20032012
Manuel Castro, Flavio D'Amico, Francisco Jablonski +1
The black hole system 1E1740.72942 is usually the brightest hard X-ray source (above 20 keV) near the Galactic Center, but presents some epochs of low emission (be…
Probing the emission physics and weak/soft population of Gamma-Ray Bursts with LOFT
L. Amati, G. Stratta, J. -L. Atteia +36
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
Confirming the thermal Comptonization model for black hole X-ray emission in the low-hard state
M. Castro, F. D'Amico, J. Braga +3
Hard X-ray spectra of black hole binaries in the low/hard state are well modeled by thermal Comptonization of soft seed photons by a corona-type region with \thinspace…
