Speaker: Shah Mohammad Bahauddin, PhD, Research Faculty, Laboratory for Atmospheric and Space Physics (LASP), Astrophysical & Planetary Sciences Department, University of Colorado, Boulder, USA. Abstract: The next frontier of astronomy lies in leveraging the unique environments of space and the Moon to unlock unprecedented scientific discoveries. This presentation will explore the speaker's journey of transforming […]

Speaker: Istiak Akib, PhD candidate, Laboratoire d'Instrumentation et de Recherche en Astrophysique (LIRA), Observatoire de Paris, Paris Sciences et Lettres University (PSL). Abstract: Fitting the flat rotation curves of the Galaxies indicate vast majority of the matter content in the galaxies is dark matter, even higher than the cosmological estimate of 85% and giving rise […]

Speaker: Tanveer Karim, PhD, Postdoctoral Fellow at the David A. Dunlap Department of Astronomy & Astrophysics, University of Toronto, and a member of the Dark Energy Spectroscopic Instrument (DESI) collaboration and the Dark Energy Science Collaboration (DESC). Abstract: Over the past decade, cosmology has encountered significant tensions between different measurements of key cosmological parameters, particularly […]

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 […]

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 […]

Title: Between Stars and Planets: Unveiling the Hidden World of Transiting Brown Dwarfs Speaker: Md Redyan Ahmed, PhD candidate, Sydney Institute for Astronomy (SIfA), University of Sydney, Australia. Abstract: Transiting brown dwarfs occupy the mass range between stars and planets, placing them in a unique regime where the physics of both worlds begin to overlap. […]

Speaker (in person): Istiak Akib, PhD candidate, Laboratoire d’Instrumentation et de Recherche en Astrophysique (LIRA), Observatoire de Paris, Paris Sciences et Lettres University (PSL), France. Abstract: The last major merger of the Milky Way (MW) occurred 9-10 Gyr ago with an incoming galaxy known as the Gaia-Sausage Enceladus (GSE). We present the first hydrodynamical modelling […]
