[Okc-wp4] EO meeting on Dec 6

[Andre Schneider]

Dear all,

our next speaker at the EO meeting (Dec 6, 13:00, @KTH meeting room on the 5th floor), will be Ragnhild Lunnan. Below is the info on her talk.



Rapidly Evolving Transients in the ZTF Era


Large-scale untargeted optical surveys are discovering many new types of transient phenomena beyond the standard Type Ia and core-collapse supernova paradigm. One relatively unexplored part of parameter space is transients with shorter timescales (~days rather than ~weeks), as traditional supernova searches were not particularly sensitive to such events. Analysis from the Pan-STARRS Medium Deep Survey suggests such transients constitute as much as 4-7% of the core-collapse supernova rate, however. In this talk, I will review previous work on rapidly evolving transients as well as discuss some recent, interesting events from iPTF and ZTF.
