Schedule | Microlensing 25

Schedule of the
25th International Microlensing Conference

All times are listed in Paris time zone (UTC+2).
The conference schedule is subject to change until the end of August, 2022.

The conference schedule has several topic sessions, some of which are split into two or three parts. Please note that these parts do not always follow one another (not back-to-back) due to scheduling considerations of all participants, some of whom are 11 time zones away from Paris. Each session color refers to a specific topic.

The pre-recorded talks and posters will be available on this page from August 24th. Pre-recorded talks and posters are considered as important as any other contributed talk by the Scientific Organizing Committee. We warmly encourage all the participants to watch them before the start of the conference. Pre-recorded talks and posters are organized in sessions matching the in-person meeting sessions.

Last update: August 28, 2022.
