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 […]

From November 17 to 21, in CASSA’s second workshop, 30 students from 10 universities in Bangladesh participated in building, for the first time in the country, a Transient Array Radio Telescope (TART). The workshop instructor was Dr. Tim Molteno from the University of Otago in New Zealand, the lead designer of TART. After seven countries […]
Speaker (in person at IUB): Tonima Tasnim Ananna, PhD, Assistant Professor, Department of Physics and Astronomy, Wayne State University, USA Title: Catching a star: How modern astronomers find exciting phenomena Abstract: Modern astrophysics infers extreme phenomena from precise, theory-driven signatures. In this talk, we will explore the empirical case for the Big Bang—cosmic expansion, light-element […]
