Time-Domain Astronomy
in the Multi-Messenger Era

Science Sessions - Time Domain

Time-domain astronomy has made great progress in the past decade. Dedicated transient surveys have revealed the population of new transients, such as superluminous supernovae and rapid-evolving transients. Transient surveys have also uncovered behaviors of the first moments of supernova explosions, which largely expands our understanding of stellar evolution. Time-domain surveys are also playing key roles in newly emerged multi-messenger astronomy, highlighted by observations of electromagnetic counterparts of gravitational wave sources and high-energy neutrino sources.

This conference aims at reviewing the recent progress in time-domain astronomy and discussing prospects of this field in the multi-messenger era. The conference will mainly cover the following topics.
・Outcomes from deep, wide and high cadence transient surveys
・Multi-messenger observations of gravitational wave and high-energy neutrino sources
・Future of multi-wavelength time-domain astronomy with big data
