Long and faint GRBs in archival BeppoSAX-WFC data
J. J. M. in 't Zand, J. Heise, R. M. Kippen +4
In an ongoing effort to search for X-ray transients on diverse time scales in the data archive of the BeppoSAX Wide Field Cameras we have identified four GRBs that are long (betwee…
The bright optical afterglow of the long GRB 001007
J. M. Castro Cerón, A. J. Castro-Tirado, J. Gorosabel +35
We present optical follow up observations of the long GRB 001007 between 6.14 hours and ~468 days after the event. An unusually bright optical afterglow (OA) was seen to decline fo…
Near-infrared detection and optical follow-up of the GRB990705 afterglow
N. Masetti
Optical and near-infrared observations of the GRB990705 error box were carried out with ESO telescopes at La Silla and Paranal in Chile and with the NOAO SPIREX 0.6-meter telescope…
BeppoSAX observations of Mkn 3: Piercing through the torus of a Seyfert 2 galaxy
M. Cappi, L. Bassani, A. Comastri +15
A new BeppoSAX broad-band (0.6-150 keV) spectrum of the Seyfert 2 galaxy Mkn 3 is presented. The spectrum provides a direct measurement of a large, neutral column of gas with Nh~10…
Evidence for a late-time outburst of the X-ray afterglow of GB970508 from BeppoSAX
L. Piro, L. Amati, L. A. Antonelli +15
The gamma-ray burst GB970508 was observed simultaneously by the Gamma Ray Burst Monitor (GRBM) and one of the X-ray Wide Field Cameras (WFC) aboard BeppoSAX. The latter provided a…
