The 1998 outburst of the X-ray transient XTE J2012+381 as observed with BeppoSAX
S. Campana, L. Stella, T. Belloni +5
We report on the results of a series of X-ray observations of the transient black hole candidate XTE J2012+381 during the 1998 outburst performed with the BeppoSAX satellite. The o…
TeV candidate BL Lac objects
L. Costamante, G. Ghisellini
The TeV emission of low power BL Lac objects has been established by the detection of an handful of them. The knowledge of the level of the TeV emission and its spectrum can shed l…
BeppoSAX Spectral Survey of BL Lacs - new spectra and results
V. Beckmann, A. Wolter, A. Celotti +4
We present BeppoSAX LECS, MECS, and PDS spectra of eleven X-ray selected BL Lacertae objects. Combining these sources with the ones presented elsewhere we have a sample of 21 BL La…
Transient Phenomena and Outbursts from Galactic Black-Hole Candidates
Tomaso Belloni
The RossiXTE mission provided us with an unprecedentedly large database of X-ray observations of transient black-hole candidates. These systems are crucial for the understanding of…
Photometric variability in the old open cluster M 67. II. General Survey
K. G. Stassun, M. van den Berg, R. D. Mathieu +1
We use differential CCD photometry to search for variability in BVI among 990 stars projected in and around the old open cluster M 67. In a previous paper we reported results for 2…
Hard X-ray states and radio emission in GRS 1915+105
M. Klein-Wolt, R. P. Fender, G. G. Pooley +4
We have compared simultaneous Ryle Telescope radio and Rossi X-Ray Timing Explorer X-ray observations of the galactic microquasar GRS 1915+105, using the classification of the X-ra…
