On the 31st of October, IEEE AESS BRACU SB conducted a workshop on the topic of Observational Cosmology. The workshop was conducted in 2 days—October 31 and November 1 respectively. The event time on both days was 7:00 PM local time. The event was moderated by Samiu Mostafa Ishan, Vice-Chair at IEEE AESS BRACU SB and the speaker for this event was Syeda Tasnuva Jahan, Lecturer at the Department of Mathematics and Natural Sciences, BRAC University, who did her postgraduate studies in Relativistic Theoretical Physics from Aix-Marseille University in France.

The workshop Day-1 commenced with a brief introduction of the speaker by Samiu Mostafa Ishan, after which Syeda Tasnuva Jahan took the helm with the introduction of observational cosmology. Her discussion started off with the essential pillars of the Big Bang model, major events that took place in the history of our universe and different cosmological parameters. In the second segment of the day, the discussion shifted towards certain detection techniques such as photometric systems, magnitudes and filters. The workshop on Day-1 came to a conclusion after a brief Q&A session with the participants.

The implementation of the ideas discussed on Day-1 were the key aspects of Day-2. Distances in the FRW metric, such as redshift, angular distance and luminosity distance were the topics that were discussed in detail. After that, the second segment on day 2 was the evolution of the galaxy, where the ascent and the descent of galaxies in the universe were the major discussions.

The workshop ended with an engaging Q&A session by the speaker with the participants and with a brief farewell speech by Samiu Mostafa Ishan, the curtains were drawn to the event.
