Speaker (online): Kenneth C. Wong, PhD, Assistant Professor, Research Center for the Early Universe (RESCEU), University of Tokyo, Japan. Abstract: Strong gravitational lensing is sensitive to the total mass distribution along the line of sight, making it a unique probe of dark matter in galaxies and clusters, and useful for studying resolved properties of the […]

Speaker (online): Tabassum Shahriar Tanvir, Postdoc Research Associate, Department of Physics and Astronomy, Iowa State University, USA. Title: Environmental variations of the low-mass IMF Abstract: The stellar initial mass function is arguably the most important distribution in astrophysics since it is at least partly determining everything from chemical evolution to the strength of stellar feedback […]

Speaker (online): Biprateep Dey, PhD, Postdoctoral Fellow, Department of Statistical Sciences, University of Toronto, Canada. Title: Photometric Redshifts for Next-Generation Sky Surveys Abstract: Knowing the distances to galaxies as measured by their cosmological redshift is crucial for studies of cosmology, galaxy evolution, and astronomical transients. The next generation of astronomical imaging surveys (like LSST, Euclid, […]
Speaker (online): Pritom Mozumdar, Postdoctoral Researcher, Department of Physics and Astronomy, University of California, Los Angeles, USA. Title: Probing galaxy evolution using massive early-type galaxies at intermediate redshift Abstract: Over the past 8 billion years (since redshift, z ~ 1), the Universe - and the galaxies within it - have changed dramatically. Cosmological simulations suggest […]
