“The new challenges of cosmology”

After the success of the white night of astronomy in 2019, the Institut d'astrophysique de Paris (IAP) is organizing a new “Astronomy night - The new challenges of cosmology”, on Friday, June 26, 2020, from 7 p.m. to midnight. This evening will be part of a larger event, “The web in the stars” (in French), organized jointly by IAP and the Université de Paris-Saclay.

The overnight program will feature live and online lectures by young researchers from the lab. PhD students from IAP will take part in the event, and will try to summarize their thesis work in three minutes (in keeping with “My thesis in 180 seconds”, in French).

The evening will be hosted by Alice Thomas, videographer and science journalist, accompanied by Alexandre Barthélemy, PhD student in the lab. The Café des sciences' drawers (in French) will give live sketches of the speakers and present their drawings live on line.

The health crisis does not allow us to welcome the public in the institute. All presentations will be transmitted live on the Twitch channel Space_Thomalice. Internet users will be able to ask questions and interact with the speakers via the chat on Twitch. At the end of the evening, everyone will be able to take part in an online quiz that will be hosted by the video artists.

The live broadcast site is here, and the replay on YouTube is there.
