The optical/IR counterpart of the 3 July 1998 gamma-ray burst and its evolution

A. J. Castro-Tirado, M. R. Zapatero-Osorio, J. Gorosabel +21

We imaged the X-ray error box of GRB 980703, beginning 22.5 hours after the gamma--ray event, in both the optical R and near-infrared H bands. A fading optical/IR object was detect…

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…

BeppoSAX observation of 4U1626-67: Discovery of an absorption cyclotron resonance feature

M. Orlandini, D. Dal Fiume, F. Frontera +6

We report on an observation of the low-mass X-ray binary 4U1626-67 performed during the BeppoSAX Science Verification Phase. An absorption feature at ~37 keV, attributable to elect…

The broad band spectral properties of galactic X-ray binary pulsars

D. Dal Fiume, M. Orlandini, F. Frontera +6

BeppoSAX observed several galactic binary X-ray pulsars during the Science Verification Phase and in the first year of the regular program. The complex emission spectra of these so…

High Energy Properties of X-ray Sources observed with BeppoSAX

F. Frontera, D. Dal Fiume, G. Malaguti +6

We report on highlight results on celestial sources observed in the high energy band (>20 keV) with BeppoSAX. In particular we review the spectral properties of sources that belong…

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…
