Series: Astronomy Colloquium

Time: 16:05-17:00 (4:05-5:00 pm)
Location: Zoom
Speaker: Dr. Sultan Hassan (NYU)
Title: Extracting all information from future surveys

Extracting the maximum amount of astrophysical and cosmological information remains a challenge in the current and future surveys. These include, for instance,the recently launched NASA’s James Webb Space Telescope (JWST), the Euclid, the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx), the Nancy Grace Roman Space Telescope (Roman), Square Kilometre Array (SKA), and many more. Due to the unprecedented sensitivity and large field of view, future surveys will enable detecting the majority of high redshift sources (quasars and galaxies) responsible for reionization on extremely large scales (> Gpc). Hence, a new generation of theoretical models and techniques is required to maximize the scientific return of these future surveys. In this talk, I will briefly discuss the key questions about the nature of reionization and the various different probes. I will also discuss uncertainties in our current theoretical models and the progress that has been made to answering these questions. I will then present some of my own contributions to improve modeling reionization using a combination of state-of-the-art simulations and machine learning techniques. I will conclude by summarizing my current and future research directions, research group philosophy, and vision to promote diversity, equity and inclusion at the University of Maryland.

In-person colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer Dr. Leslie Sage. Lunch will normally be reserved for the speaker to talk to graduate students. Anyone asking a question during a talk is asked to raise their hand and be acknowledged before speaking. Contact Dr. Leslie Sage for details.
