Princeton University Dark Cosmos Seminar

Count Your Halos
4:00pm|Jadwin Hall, Joe Henry Room

Abstract: One of the strongest predictions of the standard cold dark matter paradigm is the hierarchy of structure down to Earth-mass scales.  However, individual self-bound clumps of dark matter--"halos"--are difficult to detect directly.  Instead...

Princeton University Donald R. Hamilton Colloquium Series

Exploring the Universe with Gravitational Waves
Laura Cadonati
4:00pm|Jadwin Hall A-10

Abstract: A new era in astrophysics was inaugurated with the 2015 discovery of gravitational waves from the collision of two black holes in data from the Laser Interferometer Gravitational-wave Observatory (LIGO). Since then, LIGO and its sister...

Deforming Soft Algebras for Gauge Theory
Sruthi Narayanan
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor & Zoom

Abstract: Celestial holography aims to uncover aspects of a theory of quantum gravity in asymptotically flat spacetime by studying a putative dual "celestial" conformal field theory (cCFT) that lives on its boundary. A primary way to do this is to...

The Black Hole at Our Galactic Center
4:00pm|Jadwin Hall A-10

Abstract: At the center of our Milky Way Galaxy lives a compact massive object called Sagittarius A* (Sgr A*) which is believed to be a black hole. Its mass, as inferred from the orbits of gravitationally bond stars as well as from direct images...

Fully Nonlinear ray-tracing in Cosmological Simulations with Numerical Relativity
Hayley Macpherson
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor & Zoom

Abstract: High-precision cosmological surveys are due to deliver measurements accurate to the percent level. In order to ensure we correctly interpret these data, we need to be sure that our cosmological model is accurate. A key component of the...

High-Precision Measurement of the W boson Mass with the CDF II Detector
Bo Jayatilaka
4:00pm|Jadwin Hall, Joe Henry Room

Abstract: The mass of the W boson, a mediator of the weak force between elementary particles, is tightly constrained by the symmetries of the standard model of particle physics. The Higgs boson was the last missing component of the model. After...

Princeton University High Energy Physics Seminar

Searching for Uncovered and Unexpected New Physics Signatures at the Energy Frontier
Julia Lynne Gonski
2:00pm|*Jadwin Hall, Room 407, PCTS Seminar Room*

Abstract: The 2012 discovery of the Higgs boson with the Large Hadron Collider (LHC) was a groundbreaking achievement for high energy physics. Remaining puzzles such as dark matter confirm the need for beyond the Standard Model physics, and the...

Linking Force, Form and Function in Intestinal Organoids
Xavier Trepat
4:00pm|Jadwin Hall A-10

Abstract: Intestinal organoids capture essential features of the intestinal epithelium such as crypt folding, spatial compartmentalization of different cell types, and cellular movements from crypt to villus. Each of these processes and their...

Geometric Optics Approximation for the Einstein Vacuum Equations
Arthur Touati
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor & Zoom

Abstract: In this talk I will present recent work on the rigorous justification of the geometric optics approximation for the Einstein vacuum equations, and its link with the Burnett conjecture in general relativity. I will start by presenting the...
