Gamma-ray bursts (GRBs) are classified into short and long based on their duration, with short GRBs lasting less than 2 seconds. Short GRBs are thought to originate from compact object binary mergers, such as neutron star-neutron star (NS-NS) or neutron star-black hole (NS-BH) mergers. The discovery of short GRB afterglows in 2005 provided insights into their energy scale, environments, and cosmological origin. Observations of short GRBs and their afterglows can help identify electromagnetic counterparts of gravitational wave sources detected by Advanced LIGO/Virgo. Short GRBs are not associated with supernovae and are found in a mix of elliptical and spiral galaxies. Their progenitors are likely compact binary systems, not massive stars. Short GRBs have lower energy and density scales compared to long GRBs. The afterglow emission from short GRBs is similar to long GRBs but with lower energy and density. The study of short GRBs has revealed that they are cosmological in origin, with progenitors not involving massive stars. The afterglow properties of short GRBs, including X-ray, optical, and radio emissions, provide insights into their energy scale, collimation, and circumburst environments. The detection of short GRB afterglows has enabled the identification of their host galaxies and the study of their environments. The progenitors of short GRBs are likely compact binary systems, and their study is crucial for understanding the nature of these events and their electromagnetic counterparts.Gamma-ray bursts (GRBs) are classified into short and long based on their duration, with short GRBs lasting less than 2 seconds.
