Astronomy seminar: "Probes of non-standard gravity with peculiar motions and galactic satellites"
Adi Nusser (Technion)
Despite the success of the standard LambdaCDM model, it is argued that some modifications may well be motivated on theoretical and observational grounds. The talk will discuss how to…
Physics and Astronomy Colloquium: "Exploring physics beyond the standard model of particle physics with neutrinos"
Christopher Mauger (University of Pennsylvania)
Neutrinos are the most abundant type of fermion that we know exists, yet we do not understand basic properties of these particles like their masses. Since neutrinos are unaffected by strong and…
Mathematical Biology seminar: "Fertilization Regulatory Networks"
Gustavo Martínez-Mekler (Instituto de Ciencias Físicas, UNAM)
Fertilization is one of the fundamental processes of living systems. Here I will address marine external fertilization and comment on recent work on mammals. I will show…
Condensed and Living Matter Seminar: "Materials that learn from examples"
Arvind Murugan (University of Chicago)
We usually design materials to target desired behaviors that are defined in a top-down manner. Learning theory offers an alternative when desired behaviors are hard to define but easy to give examples of…
Astronomy seminar; "Cosmology in the multi-messenger era"
Macarena Lagos (University of Chicago)
We have great certainty on how gravity works around our Solar System, but on large scales we still have a considerable lack of understanding about the constituents of our universe. Furthermore…
Condensed and Living Matter Seminar: "A touch of non-linearity: mesoscale swimmers and active matter in fluids"
Daphne Klotsa (University of North Carolina)
Living matter, such as biological tissue, can be seen as a nonequilibrium hierarchical assembly of assemblies of smaller and smaller active components, where energy is consumed at many scales. The…
Astronomy seminar: "The Formation of Massive Galaxies: deep, high-redshift spectroscopy from the LEGA-C Survey and Beyond"
Rachel Bezanson (University of Pittsburgh)
Today’s massive elliptical galaxies are primarily red-and-dead, dispersion supported ellipticals. The physical process(es) driving the shutdown or “quenching” of star formation in these…
High Energy Theory seminar: "Black Holes to Algebraic Curves: Mathematical Consequences of the Weak Gravity Conjecture"
Tom Rudelius (Institute for Advanced Study)
The Weak Gravity Conjecture holds that in any consistent theory of quantum gravity, gravity must be the weakest force. This simple proposition has surprisingly nontrivial consequences for physics, which…
