The runaway black hole GRO J1655-40
I. F. Mirabel, R. Mignani, I. Rodrigues +3
We have used the Hubble Space Telescope to measure the motion in the sky and compute the galactocentric orbit of the black hole X-ray binary GRO J1655-40. The system moves with a r…
Supernova remnants and gamma-ray sources
Diego F. Torres, Gustavo E. Romero, Thomas M. Dame +2
A review of the possible relationship between gamma-ray sources and supernova remnants (SNRs) is presented. Particular emphasis is given to the analysis of the observational status…
Supernova-Remnant Origin of Cosmic Rays?
Yousaf M. Butt, Diego F. Torres, Gustavo E. Romero +2
It is thought that Galactic cosmic ray (CR) nuclei are gradually accelerated to high energies (up to ~300 TeV/nucleon, where 1TeV=10^12eV) in the expanding shock-waves connected wi…
Is The Enigmatic Source 3EG J1828+0142 a Galactic Microblazar ?
Yousaf Butt, Diego Torres, Gustavo Romero +5
The unidentified EGRET source 3EG J1828+0142, located at (l,b) ~ (31.9,5.8) (Hartman et al. 1999), is particularly enigmatic since it displays very high variability over timescales…
Molecular Beam Dumps as Tracers of Hadronic Cosmic Ray Sources: the Case of SNR IC443
Yousaf M. Butt, Diego F. Torres, Jorge A. Combi +2
The gamma-ray & neutrino visibility of cosmic ray (CR) accelerators will be dramatically increased by the presence of molecular material abutting such sites due to the increased pr…
Optical microvariability of EGRET blazars
G. E. Romero, S. A. Cellone, J. A. Combi +1
We present results of a photometric CCD study of the incidence of microvariability in the optical emission of a sample of 20 blazars detected at gamma-ray energies by the EGRET ins…
