Physics and Astronomy Colloquium: “Pursuing cosmic puzzles with galaxy surveys”
Bhuvnesh Jain (University of Pennsylvania)
The universe is expanding faster than any reasonable theoretical prediction! This challenge to the standard model of cosmology frames the interpretation of the Dark Energy Survey and other…

Mathematical Biology seminar: "Mechanisms Underlying Spatiotemporal Patterning in Microbial Collectives: A Model's Perspective"
Bhargav Karamched (Florida State University)
We describe a spatial Moran model that captures mechanical interactions and directional growth in spatially extended populations. The model is analytically tractable and completely solvable…
High Energy Theory Seminar: Symmetries, soft theorem and positivity in the sky
Sam Wong (UPenn)
Cosmological correlators is a young field while its sibling, scattering amplitudes, has been studied thoroughly. We consider the implication of non-linearly realized symmetries in cosmology for…
Mathematical Biology seminar: "Automated Feature Extraction from Large Cardiac Electrophysiological Data Sets"
Peter Hinow (University of Wisconsin-Milwaukee)
A multi-electrode array-based application for the long-term recording of action potentials from electrogenic cells makes possible exciting cardiac electrophysiology studies in health…
High Energy Theory Seminar: Compact dimensions: how many and how small?
Thomas Van Riet (Leuven University)
I will discuss the rather striking situation that confronts us in the context of conventional string phenomenology: 3 spatial dimensions are of Hubble size and 6 other ones are of sizes much smaller than…
Astronomy Seminar: Astronomy in the Era of Mega-constellations of Low Earth Orbiting Satellites
Tony Tyson (UC Davis)
A number of companies and governments are in various stages of planning or deploying bright satellites in low-Earth orbit in unprecedentedly …
Mathematical Biology seminar: "Stochastic Modeling of Reaction-Diffusion Processes in Biology"
Hye-Won Kang (University of Maryland Baltimore County)
Inherent fluctuations may play an important role in biochemical and biophysical systems when the system involves some species with low copy numbers. This talk will present the recent work on the…
Mathematical Biology seminar: "Fluid mechanics of the respiratory system and active coating materials"
Arnold Mathijssen (University of Pennsylvania)
Our airways are continuously exposed to potentially harmful particles like dust and viruses. The first line of defence against these pathogens is a network of…
