What is the role of luck and serendipity in discovery, and how much is sheer grit? Come hear from a Nobel laureate, Breakthrough prize winners, and several of the most exciting physicists working today on how luck -- or the lack of it -- shapes discovery.
Cosmology and astrophysics with the extragalactic light: background and fluctuations
Abstract: The aggregate light emitted by all extragalactic sources can be measured either as an absolute intensity or through its spatial fluctuations; these are known as line-intensity mapping (LIM) when a particular line transition is targeted. I will discuss how these measurements can be used both to learn about galaxy evolution and to investigate the presence of more speculative sources of radiation, such as decaying dark matter. I will then discuss the prospects of LIM to probe the interstellar and intergalactic medium, as well as structure on large scales. In particular, I will focus on the joint information across different line transitions and across different tracers, such as galaxies and extragalactic CMB foregrounds.
