Is the Supernova Remnant RX J1713.7-3946 a Hadronic Cosmic Ray Accelerator ?
Yousaf M. Butt, Diego F. Torres, Jorge A. Combi +2
The non-thermal supernova remnant RX J1713.7-3946 (G347.3-0.5) has recently been shown to be a site of cosmic ray (CR) electron acceleration to TeV energies (Muraishi et al. 2000).…
Variable gamma-ray emission from the Be/X-ray transient A0535+26?
Gustavo E. Romero, M. M. Kaufman Bernado, Jorge A. Combi +1
We present a study of the unidentified gamma-ray source 3EG J0542+2610. This source is spatially superposed to the supernova remnant G180.0-1.7, but its time variability makes unli…
A Study of the Unidentified Gamma-Ray Source 3EG J1828+0142
Jorge A. Combi, Gustavo E. Romero, Diego F. Torres +1
We present a study of the radio environment of the gamma-ray source 3EG J1828+0142. This source presents a very high variability index in its gamma emission and a steep high-energy…
The radio surroundings of the microquasar GRO J1655-40
J. A. Combi, G. E. Romero, P. Benaglia +1
We report the results of a study of the radio surroundings of the superluminal microquasar GRO J1655-40. We have searched for extended continuum structures that might be indicative…
Detection of a new, low-brightness supernova remnant possibly associated with EGRET sources
Jorge A. Combi, Gustavo E. Romero, Paula Benaglia +1
We report on the discovery of a shell-type supernova remnant in the southern sky. It is a large (8*8), low-brightness source with a nonthermal radio spectrum, which requires backgr…
Variable Unidentified Gamma-Ray Sources Near the Galactic Plane
Gustavo E. Romero, Diego F. Torres, P. Benaglia +2
In a recent paper, Romero et al. (1999) have presented the results of a positional correlation analysis of the low-latitude unidentified gamma-ray sources in the Third EGRET catalo…
