Astronomy & Astrophysics Seminar: Strong Gravitational Lensing by Galaxy Clusters: On the Lensing of Transients
Adi Zitrin, Ben Gurion University
Over the past 2–3 decades, gravitational lensing by galaxy clusters has played key roles in various scientific areas within astronomy and astrophysics. These include, primarily, mapping the otherwise-invisible dark matter distribution in the lens or weighing the clusters for constraining structure formation and cosmology; as well as enabling a deeper view into high-redshift galaxies, thanks to lensing magnification. Over the past five years or so, there have been some new, exciting developments that allow for more unprecedented science using strong lensing — involving lensed transients such as lensed supernovae and caustic crossing events, or lensed gamma-ray bursts, fast radio bursts, and gravitational waves. In this talk I will review some of these advancements, as well as take the opportunity to mention some relevant programs in which we are involved.
