A multiwavelength analysis of a collection of short-duration GRBs observed between 2012 and 2015

We investigate the prompt emission and the afterglowproperties of short duration gamma-ray burst (sGRB) 130603B and another eight sGRB events during 2012-2015, observed by several multi-wavelength facilities including the GTC 10.4m telescope. Prompt emission high energy data of the events were obtained by INTEGRAL/SPI/ACS, Swift/BAT and Fermi/GBM satellites. The prompt emission data by INTEGRAL in the energy range of 0.1-10 MeV for sGRB 130603B, sGRB 140606A, sGRB 140930B, sGRB 141212A and sGRB 151228A do not show any signature of the extended emission or precursor activity and their spectral and temporal properties are similar to those seen in case of other short bursts. For sGRB130603B, our new afterglowphotometric data constraints the pre jet-break temporal decay due to denser temporal coverage. For sGRB 130603B, the afterglowlight curve, containing both our new as well as previously published photometric data is broadly consistent with the ISM afterglowmodel. Modeling of the host galaxies of sGRB 130603B and sGRB 141212A using the LePHARE software supports a scenario in which the environment of the burst is undergoing moderate star formation activity. From the inclusion of our late-time data for 8 other sGRBs we are able to; place tight constraints on the non-detection of the afterglow, host galaxy or any underlying kilonovaemission. Our late-time afterglowobservations of the sGRB 170817A/GW170817 are also discussed and compared with the sub-set of sGRBs.
