Constraints on a local population of faint short duration GRBs are then provided in light of the GW170817/GRB 170817A event at d~40 Mpc by considering statistical limits on a d < 200 Mpc population. Using past and current GRB detectors, results suggest that GRB 170817A-like events are likely to be rare in existing short GRB catalogues and, if binary neutron star merger rates are at the high end of current estimates, then at most a few percent will be accompanied by detectable gamma-ray flashes in the forthcoming LIGO/Virgo science runs. Indirect information on the nature of short GRBs can be obtained from their host galaxy. The host galaxies of most short GRBs are found to be star-forming, but an important fraction, ?1/5, are elliptical with negligible star formation. Short bursts often occur at very large off-sets from their hosts, in regions where there is little or no underlying host light. These results provide evidence of progenitors associated with merger of compact object binaries with kick velocities of a few tens of km/s and merger times of ?1 Gyr. The last two issues of the book tackle the physics of the short GRB radiative processes. Interestingly, it was already noted in the past that the prompt emission for short GRBs and the initial 2 s of long-duration GRBs show similarity in the low energy photon index. This result has been further confirmed using a larger sample of Fermi Gamma-ray burst monitor data. In particular, it has been found that for 25% of GRBs, the photon index is shallower than ?2/3, challenging the standard synchrotron emission scenario. The extent up to which the reverse shock component is detectable for short GRBs in radio wavelengths is analyzed. Results show that early, radio bright reverse shock is expected in many cases, but more rapid follow-up observational campaigns are required in order to test these predictions.] 610 $agalaxies 610 $ahost galaxies 610 $agamma-ray bursts 610 $agamma-ray burst 610 $aGW170817 610 $acompact object mergers 610 $ashort GRBs 610 $aprompt emission 610 $aprogenitors 610 $ashort gamma-ray bursts 610 $aspectrum 610 $aphysics 610 $abinary neutron stars 700 $aStratta$b Giulia$01305968 702 $aDainotti$b Maria Giovanna 702 $aRossi$b Andrea 801 0$bScCtBLL 801 1$bScCtBLL 906 $aBOOK 912 $a9910367756903321 996 $aObservations and Theory of Short GRBs at the Dawn of the Gravitational Wave Era$93028078 997 $aUNINA
