High Energy Theory Seminar: "Modified thermal histories and the small-scale matter power spectrum"
Jessie Shelton (University of Illinois, Urbana-Champaign)
Decoupled hidden sectors in the early universe can easily and generically result in departures from radiation domination prior to BBN, leaving a potentially observable footprint in the distribution of…
Astronomy Seminar: LIMFAST: a Semi-numerical Tool for Line Intensity Mapping
Lluis Mas-Ribas (JPL)
Intensity Mapping (IM) is emerging as a promising technique to study the evolution of the universe from the Cosmic Dawn down to the present day, and this…
Mathematical Biology seminar: "A story on relocation strategies, the Allee effect, and the Ideal Free Distribution"{
Nancy Rodriguez (University of Colorado Boulder)
It is well known that relocation strategies in ecology and in economics can make the difference between extinction and persistence. In this talk I present a unifying model for the…
High Energy Theory Seminar: Recent Developments on the Swampland Distance Conjecture
Irene Valenzuela (Harvard)
In this talk I will discuss recent developments on the Swampland Distance Conjecture (SDC). This conjecture is at the core of the Swampland program, which aims to determine the constraints that any EFT…

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…
