High Energy Theory Seminar: Cornering axion(s) with direct detection and stellar probes

Edoardo Vitagliano (Hebrew U.)
- David Rittenhouse Laboratory, 3W2

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)
- David Rittenhouse Laboratory, 4N12

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…



Condensed and Living Matter Seminar: Topological Defects in Computational Meshing

David Palmer (Harvard University)
- David Rittenhouse Laboratory, A8

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…



Experimental Particle Physics Seminar: Muon trigger system and search for supersymmetry

Kaito Sugizaki (University of Tokyo)
- David Rittenhouse Laboratory, 3W2

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)
- David Rittenhouse Laboratory, 4E19

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…



High Energy Theory Seminar: de Sitter as an Axion Detector

John Stout (Harvard)
- David Rittenhouse Laboratory, 3W2

Axions, scalar fields with compact field spaces, are some of the most well-motivated candidates for physics beyond the Standard Model. In this talk, I will explain how inflationary correlations are uniquely sensitive…



High Energy Theory Seminar: Squaring Charges and finding Black Holes

Mariana Carrillo Gonzalez (Imperial)
- David Rittenhouse Laboratory, 2E17

Nowadays, we have an outstanding grasp of gauge theories on both experimental and theoretical fronts. Meanwhile, our understanding of gravitational physics has advanced greatly, but many mysteries remain…



Experimental Particle Physics Seminar: Search for Emerging Jets at CMS

Yi-Mu Chen (University of Maryland)
- David Rittenhouse Laboratory, 3W2

I present the search for emerging jets produced in proton-proton collisions at a center-of-mass energy of 13 TeV performed using data collected by the CMS experiment corresponding to an integrated luminosity of 138…



Astrophysics Seminar: ML x Cosmology with 50 Million Galaxies

ChangHoon Hahn (Princeton University)
- David Rittenhouse Laboratory, 4E19

The 3D spatial distribution of galaxies encodes key cosmological information that can be used to probe the nature of dark energy and measure the sum of neutrino masses. The next…
