Journal ArticleDOI
A new Comptonization model for low-magnetized accreting neutron stars in low mass X-ray binaries
TL;DR: In this paper, a new model for the X-ray spectral fitting \xspec package which takes into account the effects of both thermal and dynamical (i.e. bulk) Comptonization was developed.
Journal ArticleDOI
BeppoSAX observation of 4U1626-67: Discovery of an absorption cyclotron resonance feature
Mauro Orlandini,D. Dal Fiume,F. Frontera,S. Del Sordo,Santina Piraino,Andrea Santangelo,A. Segreto,T. Oosterbroek +7 more
TL;DR: In this paper, an absorption feature at � 37 keV, attributable to electron cyclotron resonance, has been discovered in the pulse averaged spectrum of the low-mass X-ray binary 4U1626-67 performed during the BeppoSAX Science Verification Phase.
Journal ArticleDOI
The Discovery of the Radio Afterglow From the Optically Dim Gamma-Ray Burst of March 29, 1998
TL;DR: In this article, the authors reported the discovery of a variable radio source, VLA J070238.0+385044, associated with the proposed x-ray counterpart, 1SAX J0702.

TL;DR: In this article, the authors studied the optical transient of the gamma-ray burst of May 8, 1997 (GRB 970508) at the 2.5m Nordic Optical Telescope (NOT) and 2.2m telescope at the German-Spanish Calar Alto observatory (CAHA) covering the time interval starting 3 hours 5 minutes to 96 days after the high energy event.

TL;DR: In this article, the optical counterpart to GRB 980326 was discovered and its rapid optical decay was characterized by a power law with exponent - 2.10+/-0.13 and a constant underlying source at R{c}}=25.5.
