Gamma-Ray Bursts: the Four Crises
Marco Tavani
We discuss some open problems concerning the origin and the emission mechanism of gamma-ray bursts (GRBs) in light of recent developments. If GRBs originate at extragalactic distan…
The HI fine structure of HVC187 near NGC3783, gas in the leading bridge of the Magellanic System
B. P. Wakker, B. D. Savage, T. A. Oosterloo +1
We present an analysis of high-resolution HI data of one of the cores of HVC187 Wakker & van Woerden 1991), HVC287+22+240. Structure is present down to the lowest-measurable scale…
Gamma-Ray Burst 980329 and its X-Ray Afterglow
J. J. M. in 't Zand, L. Amati, L. A. Antonelli +16
GRB 980329 is the brightest gamma-ray burst detected so far with the Wide Field Cameras aboard BeppoSAX, both in gamma-rays and X-rays. With respect to its fluence (2.6 X 10**-5 er…
BeppoSAX observations of a new X-ray burster in the Galactic Center region, possibly coincident with a recurrent transient
L. Sidoli, S. Mereghetti, G. L. Israel +3
We report BeppoSAX NFI observations of the X-ray source SAX~J1747.0--2853 recently discovered in the region of the Galactic Center. The presence of type I X-ray bursts indicates th…
The Neutron Stars of Soft X-Ray Transients
S. Campana, M. Colpi, S. Mereghetti +2
Soft X-ray Transients (SXRTs) have long been suspected to contain old, weakly magnetic neutron stars that have been spun up by accretion torques. After reviewing their observationa…
Aquila X-1 from outburst to quiescence: the onset of the propeller effect and signs of a turned-on rotation-powered pulsar
S. Campana, L. Stella, S. Mereghetti +5
We report on the March-April 1997 BeppoSAX observations of Aql X-1, the first to monitor the evolution of the spectral and time variability properties of a neutron star soft X-ray…
HST/FOC observations confirm the presence of a spectral feature in the optical spectrum of Geminga
R. P. Mignani, P. A. Caraveo, G. F. Bignami
New optical and near-UV HST observations of Geminga are presented. When compared with previous ground-based and HST imaging, the data confirm and better define the presence of an e…
How Abundant is Iron in the Core of the Perseus Cluster?
S. Molendi, G. Matt, L. A. Antonelli +5
The analysis of Perseus data collected with the Medium Energy Concentrator Spectrometer (MECS) on board Beppo-SAX shows that the ratio of the flux of the 8 keV line complex (domina…
