نویسنده
چکیده
The delayed hard (up to 25 GeV) photons observed more than an hour following a gamma-ray burst on February 17, 1994 may result from the collisions of relativistic nucleons with a dense cloud, producing π 0. The required cloud density is ∼ 2 × 10 11 cm −3. This cloud may be the remains of the disrupted envelope of a neutron star, and may survive as an excretion disc of ∼ 10 14 –10 15 cm radius around the coalescing binary.

New additional equations for the Newtonian dynamical systems on Riemannian manifolds are found. They supplement the previously found weak normality conditions up to the complete normality conditions for Newtonian dynamical systems.

The SPI anticoincidence shield consists of 91 BGO crystals and is operated as a nearly omnidirectional gamma-ray burst detector above 75 keV. Since the start of the mission 269 gamma-ray burst candidates have been detected. 110 bursts have been confirmed with the instruments included in the 3rd Interplanetary Network. Here we present a preliminary statistical analysis of the SPI-ACS sample of g...

Particles with energies below the mean energy E 0 in relativistic shocked plasmas should assume an equilibrium energy distribution. This leads to a synchrotron spectrum F ν ∝ ν 1/3 up to approximately the critical frequency ν 0 of an electron with the energy E 0. Application to GRBs implies that a burst with 10 −5 erg/cm 2 s of soft gamma-rays and hν 0 = 300 KeV should be about 18th magnitude i...

We find that the optical magnitudes of GRB990123 observed by ROTSE correlates with the magnitudes extrapolated from the simultaneous BATSE spectra, strongly suggesting that the optical, X-ray and gamma-ray photons originate from a single source. We then show that the broadband optical-gamma-ray spectra can be naturally fit by the saturated Compton model. We also derive the parameters of the Com...
