The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

Observations show that at least some gamma-ray bursts (GRBs) happen simultaneously
with core-collapse supernovae (SNe), thus linking by a common thread nature's two …

In several GRBs afterglows, rapid temporal decay is observed which is inconsistent with
spherical (isotropic) blast-wave models. In particular, GRB 980519 had the most rapidly …

Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued
evolution of rotating helium stars, M α≳ 10 M⊙, in which iron-core collapse does not …

The discovery of afterglows associated with γ-ray bursts at X-ray, optical and radio
wavelengths and the measurement of the redshifts of some of these events, has established …

Gamma-ray bursts (GRBs) have puzzled astronomers since their accidental discovery in the
late 1960s. The BATSE detector on the COMPTON-GRO satellite has been detecting one …

We present the main results of a study of spectral and energetics properties of twelve
gamma-ray bursts (GRBs) with redshift estimates. All GRBs in our sample were detected by …

Two types of gamma-ray bursts (GRBs) are observed: short-duration hard spectrum GRBs
and long-duration soft spectrum GRBs. For many years long GRBs were the focus of intense …

Due to the interaction of physics and astrophysics we are witnessing in these years a
splendid synthesis of theoretical, experimental and observational results originating from …

Recent rapid progress in time domain surveys makes it possible to detect various types of
explosive transients in the Universe in large numbers, some of which will be gravitationally …
