Discovery of X-rays from the supernova remnant G0.9+0.1
L. Sidoli, G. L. Israel, L. Chiappetti +6
During the survey of the Galactic Center region, we have discovered X-ray emission from the central region of the supernova remnant G0.9+0.1. The high interstellar absor…
Recent Results on the Anomalous X-ray Pulsars
S. Mereghetti, L. Stella, G. L. Israel
The ''Anomalous X-ray Pulsars'' (AXPs) are a small group of X-ray pulsars characterized by periods in the 5-10 s range and by the absence of massive companion stars. There are now…
Pulsar Counterparts of Gamma-Ray Sources
P. A. Caraveo, G. F. Bignami
The EGRET catalogue of unidentified X-ray sources has more objects along the galactic disk than at high galactic latitude, where identifications are comparatively easier. On the ot…
Is the Fuzziness of GRB970228 constant?
P. A. Caraveo, R. P. Mignani, G. F. Bignami
In view of the data gathered in September 1997, we review the flux values collected so far for the "fuzziness" seen in the optical counterpart of GRB970228. Comparison between the…
Hipparcos Positioning of Geminga : How and Why
P. A. Caraveo, M. G. Lattanzi, G. Massone +4
Accuracy in the absolute position in the sky is one of the limiting factors for pulsar timing, and timing parameters have a direct impact on the understanding of the physics of Iso…
New limits on the orbital parameters of 1E1048.1-5937 and 1E2259+586 from RossiXTE observations
S. Mereghetti, G. L. Israel, L. Stella
We report on two RossiXTE observations of the anomalous X-ray pulsars 1E 1048.1-5937 and 1E 2259+586. Both sources have continued their almost constant spin-down during 1995/96. We…
Hubble Space Telescope Imaging of the Optical Transient Associated with GRB970508
Elena Pian, Andrew S. Fruchter, Louis E. Bergeron +15
We report on Hubble Space Telescope (HST) observations of the optical transient (OT) discovered in the error box of the gamma-ray burst GRB970508. The object was imaged on 1997 Jun…
BeppoSAX Observations of Unprecedented Synchrotron Activity in the BL Lac Object Mkn 501
Elena Pian, Giuseppe Vacanti, Gianpiero Tagliaferri +9
The BL Lac object Mkn 501, one of the only three extragalactic sources (with Mkn 421 and 1ES 2344+514) so far detected at TeV energies, was observed with the BeppoSAX satellite on…
A Determination of the Spectral Index of Galactic Synchrotron Emission in the 1-10 GHz range
P. Platania, M. Bensadoun, M. Bersanelli +5
We present an analysis of simultaneous multifrequency measurements of the Galactic emission in the 1-10 GHz range with 18 degrees, angular resolution taken from a high altitude sit…
HST Data Suggest Proper Motion for the Optical Counterpart of GRB 970228
P. A. Caraveo, R. P. Mignani, M. Tavani +1
After a quarter of a century of gamma-ray burst (GRB) astronomy, the Italian-Dutch satellite BeppoSAX on Feb 28th, 1997 detected a soft X-ray afterglow from GRB 970228 and position…
The Steepness Ratio Technique: A New Method to analyze ROSAT All-Sky Survey Extended Sources
S. De Grandi, S. Molendi, H. Böhringer +2
In this first paper of a series we develop a new technique to analyze clusters of galaxies observed during the ROSAT All-Sky Survey (RASS). We call this method the Steepness Ratio…
