Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Lauren Street, Nickolay Y. Gnedin, L. C. R. Wijewardhana, , | Summary: We perform maximum likelihood estimates (MLEs) for single and double flavor ultralight dark matter (ULDM) models using the Spitzer Photometry and Accurate Rotation Curves (SPARC) database. These estimates are compared to MLEs for several […]
Kavli Affiliate: Brian Nord | First 5 Authors: Kamilė Lukošiūtė, Geert Raaijmakers, Zoheyr Doctor, Marcelle Soares-Santos, Brian Nord | Summary: Detailed radiative transfer simulations of kilonova spectra play an essential role in multimessenger astrophysics. Using the simulation results in parameter inference studies requires building a surrogate model from the simulation outputs to use in algorithms […]
Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: Quantum field theory, which is generally used to describe the origin of large-scale gravitational perturbations during cosmic inflation, has been shown to omit an important physical effect in curved space-time, the nonlocal entanglement among quantized modes from their gravitational effect […]
Kavli Affiliate: Salman Habib | First 5 Authors: Stijn N. B. Debackere, Henk Hoekstra, Joop Schaye, Katrin Heitmann, Salman Habib | Summary: The abundance of clusters of galaxies is highly sensitive to the late-time evolution of the matter distribution, since clusters form at the highest density peaks. However, the 3D cluster mass cannot be inferred […]
Kavli Affiliate: Robert M. Wald | First 5 Authors: Kartik Prabhu, Gautam Satishchandran, Robert M. Wald, , | Summary: Infrared (IR) divergences arise in scattering theory with massless fields and are manifestations of the memory effect. There is nothing singular about states with memory, but they do not lie in the standard Fock space. IR […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Jose Maria Ezquiaga, Wayne Hu, Macarena Lagos, Meng-Xiang Lin, Fei Xu | Summary: Low-energy alternatives to General Relativity (GR) generically modify the phase of gravitational waves (GWs) during their propagation. As detector sensitivities increase, it becomes key to understand how these modifications affect the GW higher modes […]

Kavli Affiliate: Marcela Carena | First 5 Authors: Asher Berlin, Sergey Belomestnykh, Diego Blas, Daniil Frolov, Anthony J. Brady | Summary: This is a Snowmass white paper on the utility of existing and future superconducting cavities to probe fundamental physics. Superconducting radio frequency (SRF) cavity technology has seen tremendous progress in the past decades, as […]
Kavli Affiliate: Clarence Chang | First 5 Authors: Jonathan Asaadi, Dan Baxter, Karl K. Berggren, Davide Braga, Serge A. Charlebois | Summary: In the last decade, several photon counting technologies have been developed opening a new window for experiments in the low photon number regime. Several ongoing and future projects in HEP benefit from these […]
