Sultan Hassan, Ph.D.

Flatiron Research Fellow, Galaxy Formation, CCA, Flatiron InstituteSultan Hassan’s website

Sultan Hassan joined the Flatiron Institute’s Center for Computational Astrophysics as a Flatiron Research Fellow in September 2020. Sultan received his B.Sc. in Physics from the University of Khartoum, Sudan, followed by his Honours and M.Sc. in Astrophysics & Space Science from the University of Cape Town, South Africa. Sultan then earned his Ph.D. in Physics from the University of the Western Cape, South Africa. He was also a visiting fellow at the Max Planck Institute for Astrophysics in 2017. Prior to joining CCA, Sultan was SKA Postdoctoral Fellow at the University of Western Cape in 2018, and then a Tombaugh Postdoctoral Fellow at New Mexico State University from 2018 to 2020.

Sultan uses large-scale semi-numerical simulations, with insights from galaxy formation (semi-analytical and numerical) models, including high-resolution radiative-transfer simulations, to study how reionization began, evolved and completed.  Sultan also uses Machine Learning algorithms and Bayesian inference techniques to extract the maximum amount of astrophysical and cosmological information from observed and mock datasets such as SKA-like 21cm maps and QSOs spectral lines. Sultan is currently slowly shifting to small scales. Recent works include using Damped Lyα systems to test Galaxy Formation Simulations and Lyα emission around high-redshift galaxies as probe of late stages of reionization. Current interest includes ISM simulation and Wavelet Scattering Transforms.
