Gravitational Waves and Their Electromagnetic Counterparts:
On Feb. 11, 2016, Advanced LIGO team announced the discovery of the first astrophysical gravitational wave (GW) source, GW 150914. This marked the beginning of a new era of gravitational wave astronomy. Detecting possible electromagnetic (EM) counterparts of GWs is the next challenging task. When detected, the astronomy will enter the full multi-messenger era.
My group have been developing theoretical models for the EM counterparts of GWs.
NASA's Fermi GBM team announced the discovery of a putative gamma-ray transient coincident with GW 150914 (dubbed GW 150914-GBM), which occurred ~0.4 s after the merger event and lasted ~ 1s. I have developed a model to interpret this event by invoking at least one charged black hole in the merging system. The same model also gives a possible interpretation to some Fasr Radio Bursts (FRBs). This paper can be found here. See Quanta Magazine and AAS NOVA for further discussion of the model.
