India/Japan internal collaboration meeting on transients and supernovae

 on Mar 20 - 28, 2023 (hybrid)

& workshop will be held on Mar 27

in Hiroshima Astrophysical Science Center (HASC) at the Higashi-Hiroshima campus in Hiroshima University 

Aim

Observational and theoretical studies based on multi-band, spectroscopic,  polarimetric follow-up observations of remarkable/peculiar transient/supernovae discovered in recent high-frequency wide-field surveys are focused. In addition, we aim to build an organic and collaborative follow-up framework using 1-4m class telescopes among Japan and India. 


Important supplement

The program will be flexible and fluid. We would like to take plenty of discussion and break time, and spend more time for future observations and data sharing. Also, since this is an internal meeting, we welcome students who want to have experience giving presentations in English. Please choose whether you would like to participate online or onsite.


Time table

The following schedule is almost fixed. We will allocate the plenty of the time for the closed local group (India/Hiroshima/Kyoto/Kagoshima) meeting during two weeks.
