The George P. and Cynthia Woods Mitchell Institute for Fundamental Physics and Astronomy builds on the interface between Astrophysics, High Energy Experiment, and High Energy Theory to advance our knowledge and understanding of the Universe. We explore the Universe from the lightest particles to its most massive structures through vibrant research programs centered on theory, observations, and experiments. We are dedicated to sharing our knowledge and the excitement of discovery through education and public outreach, conferences, workshops, and a visitors’ program. The Mitchell Institute is part of the Department of Physics and Astronomy in the College of Science at Texas A&M University.
Manifesting the Imprints of Elastic and Exothermic Scatterings Among Dark Matter Particles in Astrophysical/Cosmological Observations HEPEC
In this talk, I will give an overview of how elastic and exothermic scatterings among dark matter particles give rise to distinctive features in late-time structure formation. I will explain how astrophysical observations on the structures of galaxies can probe such unique features, and discuss how the observations can help distinguish different dark matter models. I will then explain how the interplay between the elastic and exothermic scatterings self-heats the overall dark matter in the early Universe. I will demonstrate that self-heating is often realized in scenarios of (sub-)GeV scale non-minimal dark sector. I will discuss how self-heating leaves imprints in cosmological observables and how it affects the interpretation of direct/indirect-detection experiments. Finally, I will discuss how astrophysical/cosmological observations and accelerator-based experiments can be complementary to each other in probing multi-component dark matter scenarios.

Three new studies predict the measurement-induced phase-transition behavior for quantum systems that have long-range coupling between their qubits. Quantum computers derive their power from the complex entanglement structure that “builds” between their qubits over time. But reading out information from such a computer requires measuring the state of individual qubits, a process that can impact […]
Three years ago this month, Texas A&M University physicist Ralf Rapp was first author on a paper that currently ranks as the top-cited article among all those appearing in the peer-reviewed Elsevier journal Nuclear Physics A during the past five years. The paper, “Extraction of heavy-flavor transport coefficients in QCD matter,” summarizes the results of a […]
Two Texas A&M University faculty members — mathematician Dr. Peter Kuchment and astronomer Dr. Casey Papovich — have been elected as 2021 Fellows of the American Physical Society (APS), the world’s largest organization of physicists. Each year, no more than one-half of 1 percent of the organization’s current membership is selected by their peers for inclusion […]
