On Monday, May 08, at 11.00 am, Jerzy Pniewski and Leopold Infeld Colloquium of the Faculty of Physics will be held in room 0.06. Our guest will be dr Darko Donevski (Zakład Astrofizyki NCBJ, Warszawa & Scuola Internazionale Superiore di Studi Avanzati, Triest). He will give a lecture entitled:

"Galaxies in the early universe with the James Webb Space Telescope"

In his lecture, Dr Darko Donevski will present the results brought by the first year of operation of the James Webb Space Telescope. Located at a distance of about 1.5 million kilometres from Earth and of unique design, the telescope takes images of the cosmos that have not previously been possible to register. It is able to show what the universe looked like barely hundreds of millions of years after the Big Bang, when the first stars and galaxies began to form. The lecture promises to be a cognitively fascinating and visually appealing event.

The abstract of the lecture can be found below this message.

Before the Colloquium, at 10.30 a.m., we invite you to informal discussions over coffee and cookies in the hall in front of room 0.06.

Summary:

The James Webb Space Telescope (JWST) is the largest spacetelescope ever launched, and it is a giant leap forward in our quest to understand the universe. The JWST has already opened a new discovery space in extragalactic astronomy by revealing hundreds of distant galaxies rich in stars and dust. The detection of dust is particularly important, as dust grains host the production of molecular hydrogen, the primary fuel for star formation. As many of these gigantic galaxies are observed within the first 700 million years after the Big Bang, their abundance challenges theoretical models and opens many questions on the formation of matter in the early universe. In this colloquium, I will overview the first results and big science questions related to the origin of the most distant galaxies observed with JWST.
