Time-domain astronomy

Time-domain astronomy is the study of how astronomical objects change with time. Changes may be due to movement or physical changes in the object itself. Examples include pulsar variability, and the variability of accreting black holes, variable stars, and the Sun. This term includes both theoretical and observational studies of the time-dependent behaviour of astronomical objects.

    Tidal disruption events are an excellent probe for supermassive black holes in distant inactive galaxies because they emit bright multi-wavelength flares that last several months to years. AT2019dsg represents the first potential association of neutrino emission with such an explosive event.
