Transients Discussion Circle

Supernovae, gamma-ray bursts, tidal disruption flares, active galactic nuclei etc. In short, any transient/variable event involving explosive/accretion phenomena.

When

Every other Friday from 10:00-10:30 am in room Tramontane (second floor). Next meeting: 6 Oct 2017 (room Tramontane)
