... 4 , Chryssa Kouveliotou 5 , Paul J. Groot 3 , Titus J. Galama 3 We examine what we regard as key observational results on GRB 970228 and GRB 970508 and show that the accumulated evidence strongly suggests that -ray bursts (GRBs) are cosmological fireballs ...

... The Expanding Fireball Model and the Early UV Flux The early optical flux curves of SNe Ia are often assumed to follow the "expanding fireball" model described in Riess et al. ...
... The Tunguska fireball is estimated as having an original diameter of ~100 metres, mass of 50,000 tons, releasing an energy of ~100,000 Megatons. ...
... Convenor: Mike A'Hearn (ma@astro.umd.edu) Charter: There is still dispute about whether Galileo's SSI and PPR observed the impacting bolide, the rising fireball, or some combination of the two (NIMS clearly observed a rising fireball). ...

... ultraviolet spectroscopy and Chandra imaging obtained within two days of an outburst will allow probing the physics of the relativistic fireball and the nature of the ISM surrounding the GRB; 2} long-term optical monitoring of the optical transient {OT ...
... Nevertheless, the decay profile of the transient source is consistent with a popular impulsive-fireball model, which assumes a merger between two neutron stars in a distant galaxy. \end{abstract} \end{document} ...
