“…The classification scheme based on the bimodal nature of the duration distribution with the separation at T 90 ∼ 2 s was proposed in the BATSE/CGRO experiment, where T 90 parameter (time interval with integrated counts raise from 5% to 95%) was introduced (Kouveliotou et al 1993). Type I (short) bursts were also found to have a harder energy spectrum (e.g., in terms of a hardness ratio -the ratio of energy fluxes in different energy bands) and less distinct spectral evolution (lag) comparing with type II (long) ones (Kouveliotou et al 1993;Norris et al 2005;Minaev et al 2010aMinaev et al ,b, 2012Minaev et al , 2014.…”

We present the most extensive sample of 45 type I (short) and 275 type II (long) gamma-ray bursts (GRB) with known redshift to investigate the correlation between the rest frame peak energy, E p,i and the total isotropic equivalent energy, E iso of the prompt emission (Amati relation). The E p,i -E iso correlation for type I bursts is found to be well-distinguished from the one constructed for type II bursts and has a similar power-law index value, E p,i ∼ E 0.4 iso , which possibly indicates the same emission mechanism of both GRB types. We show that the initial pulse complex (IPC) of type I bursts with an extended emission and regular type I bursts follow the same correlation. We obtain similar results for type II bursts associated with Ic supernovae and for regular type II bursts.

“…For the first pulse, red line represents logarithmic spectral lag behavior on energy, lag ∼ 0.24 × log(E). The logarithmic approximation is typical for single pulses of GRBs (Minaev et al 2014).…”

“…A spectral lag analysis based on the CCF method (see, e.g., Minaev et al 2014) was performed for GRB 170817A using the light curves detected by GBM/Fermi (NaI: 1, 2, 5) in the energy bands (8, 50) keV, (50, 100) keV, and (100, 300) keV with a time resolution of 0.04 s. The spectral lag between (8, 50) keV and (50, 100) keV bands is negligible, lag = 0.01 ± 0.08 s, but between (8, 50) keV and (100, 300) keV lag is significant, lag = 0.27 ± 0.05 s. It might represent the hard-to-soft spectral evolution of the first pulse (see Figure 1, upper panel).…”

We present our observations of electromagnetic transients associated with GW170817/GRB 170817A using optical telescopes of Chilescope observatory and Big Scanning Antenna (BSA) of Pushchino Radio Astronomy Observatory at 110 MHz. The Chilescope observatory detected an optical transient of ∼ 19 m on the third day in the outskirts of the galaxy NGC 4993; we continued observations following its rapid decrease. We put an upper limit of 1.5 × 10 4 Jy on any radio source with a duration of 10-60 s which may be associated with GW170817/GRB 170817A. The prompt gamma-ray emission consists of two distinctive components -a hard short pulse delayed by ∼ 2 seconds with respect to the LIGO signal and softer thermal pulse with T ∼ 10 keV lasting for another ∼ 2 seconds. The appearance of a thermal component at the end of the burst is unusual for short GRBs. Both the hard and the soft components do not satisfy the Amati relation, making GRB 170817A distinctively different from other short GRBs. Based on gamma-ray and optical observations, we develop a model for the prompt high-energy emission associated with GRB 170817A. The merger of two neutron stars creates an accretion torus of ∼ 10 −2 M , which supplies the black hole with magnetic flux and confines the BlandfordZnajek-powered jet. We associate the hard prompt spike with the quasispherical breakout of the jet from the disk wind. As the jet plows through the wind with subrelativistic velocity, it creates a radiation-dominated shock that heats the wind material to tens of kiloelectron volts, producing the soft thermal component.

The next generation interferometric radio telescope, the Square Kilometre Array (SKA), which will be the most sensitive and largest radio telescope ever constructed, could greatly contribute to the detection, survey and characterization of Gamma Ray Bursts (GRBs). By the SKA, it will be possible to perform the follow up of GRBs even for several months. This approach would be extremely useful to extend the Spectrum Energetic Distribution (SED) from the gamma to the to radio band and would increase the number of radio detectable GRBs. In principle, the SKA could help to understand the physics of GRBs by setting constraints on theoretical models. This goal could be achieved by taking into account multiple observations at different wavelengths in order to obtain a deeper insight of the sources. Here, we present an estimation of GRB radio detections, showing that the GRBs can really be observed by the SKA. The approach that we present consists in determining blind detection rates derived by a very large sample consisting of merging several GRB catalogues observed by current missions as Swift, Fermi, Agile and INTEGRAL and by previous missions as BeppoSAX, CGRO, GRANAT, HETE-2, Ulysses and Wind. The final catalogue counts 7516 distinct sources. We compute the fraction of GRBs that could be observed by the SKA at high and low frequencies, above its observable sky.

This is the energy interval where a GRB should emit to be detectable in the radio band by the SKA. Results seem consistent with observational capabilities.
