Astrophysics Seminar: Synergies Between Imaging and Spectroscopic Surveys for Cosmology
Current and forthcoming sky surveys promise to deliver
datasets orders of magnitude better in quality and size than their
predecessors, but our ability to take advantage of these datasets is
…
Condensed and Living Matter Seminar: Orientational Order in Biological Development - Superfluid Shrimp
Mark Bowick (Kavli Institute for Theoretical Physics, UC Santa Barbara)
Morphogenesis, the process through which genes generate form, establishes tissue scale order as a template for constructing the complex shapes of the body plan. The extensive growth required to build…
Special Condensed & Living Matter Seminar: Mechanobiology in vivo and in 3D
Keng-hui Lin (Academia Sinica, Taiwan)
This talk will have two parts. The first part concerns the mechanical wave observed in the wound healing of zebrafish tailfin. Highly regenerative animals can regrow lost appendages and the rate of regrowth is…
Colloquium: Change Physics Culture Now
Jessica Esquivel (Fermilab)
This presentation will overview initiatives created to overcome inequity in physics. We will discuss grassroots efforts like Black in Physics, institution-adjacent efforts like Change-Now at Fermilab, and APS-funded…
High Energy Theory Seminar: Cornering axion(s) with direct detection and stellar probes
Edoardo Vitagliano (Hebrew U.)
Feebly interacting particles (FIPs), such as axions, scalars, dark photons, and majorons, are often theoretically well motivated, and a dark sector including one or more of them can both have the…
High Energy Theory Seminar: Coherence in the sky: from precision astrometry to black holes and hidden particles
Masha Baryakhtar (U. Wash)
In the era of a wealth of data from the sky, new perspectives can lead to parametric improvements in discovery reach. I will discuss two ideas that make use of surprising properties of coherent radiation to open new…
Experimental Particle Physics Seminar: Muon trigger system and search for supersymmetry
Kaito Sugizaki (University of Tokyo)
The ATLAS experiment, consisting of over 3,000 members, explores new frontiers in physics with high-energy proton-proton collisions at the LHC. In such a large collaboration, it is crucial to devote oneself to…
Astrophysics Seminar: Constraining Galaxy Formation And Baryonic Effects On LSS With Observations Of The Thermal And Kinetic SZ Effects
Nick Battaglia (Cornell University)
A new window into the growth and evolution of large-scale structure has opened up with the recent observations of the thermal and kinetic Sunyaev-Zel’dovich (SZ) effects. I will…
Condensed and Living Matter Seminar: Topological Defects in Computational Meshing
David Palmer (Harvard University)
The topological structure of a hexahedral mesh is characterized by its singularities, which look like line disclinations in a crystal. In field-based meshing, one first computes a so-called octahedral…
