Does Light Emerge from a Black Hole Merger?: Subaru+GTC Collaboration to Target Gravitational Wave Events

A research team led by researchers from the National Astronomical Observatory of Japan (NAOJ) and the Instituto de Astrofísica de Canarias (IAC) in Spain performed follow-up observations of a gravitational wave event using the Subaru Telescope and the Gran Telescopio CANARIAS (GTC) to search for electromagnetic emission from a binary black hole coalescence. The collaboration between the wide-field deep imaging capability of the Subaru Telescope and the observing flexibility of GTC played an important role in this study. The cooperative follow-up of a large number of gravitational wave events will elucidate the nature of these enigmatic phenomena.

A red circle represents the size of HSC’s field of view, equivalent to nine full moons. The yellow circle shows the size of a full moon for comparison. (Credit: NAOJ/Tominaga/PanSTARRS)
