We propose a new criterion to divide the classical gamma-ray bursts into two classes on the basis of their distribution in the duration-hardness plane. We study the two proposed classes separately, dividing them into subsets of different hardness-rat

The distribution of the sources of the Gamma-Ray Bursts (GRBs) recorded by the CGRO experiment is uniform for all directions in the sky, while the behaviour of the log N-log P suggests a space distribution of the events not homogeneous. The cosmologi

Recent observations of CGRO satellite challenged the almost universally accepted galactic origin of gamma-ray bursts and have revived the extragalactic, cosmological models. This hypothesis should imply some variations of the morphological and energe

In this paper we analyse two particularly significant cosmic gamma-ray bursts recorded by the French-Soviet experiment APEX on board the space mission PHOBOS. The October 24th 1988 event, lasting more than 16 seconds, is among the strongest events ob

Alphavirus-derived vectors are being developed for vaccine, gene therapy and recombinant protein production applications, based in part on observations of transient, high level expression of heterologous genes in eukaryotic cells. Efficient means for

We investigate by a statistical analysis possible correlations among the observational parameters of the γ-ray bursts: the rise time, the decay time and spectral hardness. We discuss the physical constraints implied by the results.

Different progenitors and physical processes could be at the origin of GRBs. New information about the properties of the gamma-ray emission can help to select among the different proposed models and possibly to identify different classes with differe

Alphaviruses have several features that make them attractive as gene delivery platforms, and vectors derived principally from Sindbis virus (SIN), Semliki Forest virus (SFV), and Venezuelan equine encephalitis virus (VEE), are currently being develop

We analyzed the GRB energy spectra obtained from the fluence values reported in the BATSE catalog, averaging the data over contiguous HR ranges. When submitted to this type of analysis, these GRB spectra show a continuous evolution with the spectral

A previous statistical analysis of the events of the BATSE 3B catalog has put in evidence the presence of two different classes of gamma-ray bursts in the plane duration-spectral hardness. The study of the two classes showed different physical charac
