==== Garching SN meeting ==== This is the group meeting for everyone interested in explosive transients of any kind. The meetings take place on **Thursday at 11 am** on [[https://zoom.us/j/95681856275?pwd=UnBxTG5yY1ZBaTF6QjVvN1E0TVVoZz09 | Zoom]] and in-person at the old MPA lecture hall (401). All announcements will be made via the mailing list ([[garching_sn_meeting@eso.org]]). Tell [[tauben@MPA-Garching.MPG.DE|Stefan Taubenberger]], [[cvogl@MPA-Garching.MPG.DE|Christian Vogl]], or [[csogeza@MPA-Garching.MPG.DE|Geza Csornyei]] if you want to subscribe! **Rough guidelines for contributions:** * You can either talk about your own research progress/hurdles/successes or present a recent paper. * Your talk should only fill 30 mins to leave time for ample discussion within the hour. * Contributions should be as informal as possible rather than seminar-type talks. ---- ====SN meeting talks in 2022==== * **18.08.2022: Aleksandar Cikota** on "An imaging polarimetry survey of
