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 […]

On the night of the last full moon of 2025, join us for a special screening of E.T. the Extra-Terrestrial (1982), directed by Steven Spielberg. Before the screening, an astronomer will offer a short introduction on the film’s enduring significance in the age of exoplanets. In the early 1980s, astronomers worldwide were searching the Milky […]
