Population-level Dark Energy Constraints from Strong Gravitational Lensing using Simulation-Based Inference

Kavli Affiliate: Brian Nord | First 5 Authors: Sreevani Jarugula, Brian Nord, Abhijith Gandrakota, Aleksandra Ćiprijanović, | Summary: In this work, we present a scalable approach for inferring the dark energy equation-of-state parameter ($w$) from a population of strong gravitational lens images using Simulation-Based Inference (SBI). Strong gravitational lensing offers crucial insights into cosmology, but […]

The Non-Relativistic Effective Field Theory Of Dark Matter-Electron Interactions

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, Duncan Rocha, Tanner Trickle, , | Summary: Electronic excitations in atomic, molecular, and crystal targets are at the forefront of the ongoing search for light, sub-GeV dark matter (DM). In many light DM-electron interactions the energy and momentum deposited is much smaller than the electron […]

When to Sweat the Small Stuff: identifying the most informative events from ground-based gravitational-wave detectors

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Daniel E. Holz, , , | Summary: We explore scaling relations for the information carried by individual events, and how that information accumulates in catalogs like those from ground-based gravitational-wave detectors. For a variety of situations, the larger number of quiet/distant signals dominates the […]

On the universality of star formation efficiency in galaxies

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Ava Polzin, Andrey V. Kravtsov, Vadim A. Semenov, Nickolay Y. Gnedin, | Summary: We analyze high-resolution hydrodynamics simulations of an isolated disk dwarf galaxy with an explicit model for unresolved turbulence and turbulence-based star formation prescription. We examine the characteristic values of the star formation efficiency […]

Design of an 8-Channel 40 GS/s 20 mW/Ch Waveform Sampling ASIC in 65 nm CMOS

Kavli Affiliate: Eric Oberla | First 5 Authors: Jinseo Park, Evan Angelico, Andrew Arzac, Davide Braga, Ahan Datta | Summary: 1 ps timing resolution is the entry point to signature based searches relying on secondary/tertiary vertices and particle identification. We describe a preliminary design for PSEC5, an 8-channel 40 GS/s waveform-sampling ASIC in the TSMC […]

Coordinated JWST Imaging of Three Distance Indicators in a SN Host Galaxy and an Estimate of the TRGB Color Dependence

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Taylor J. Hoyt, In Sung Jang, Wendy L. Freedman, Barry F. Madore, Abigail J. Lee | Summary: Boasting a 6.5m mirror in space, JWST can increase by several times the number of supernovae (SNe) to which a redshift-independent distance has been measured with a precision distance […]

Constraints on blue and red tilted primordial power spectra using dwarf galaxy properties

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Ariane Dekker, Andrey Kravtsov, , , | Summary: Although the standard $Lambda$+Cold Dark Matter ($Lambda$CDM) model is well tested on large scales, the primordial power spectrum may deviate from the $Lambda$CDM spectrum on small scales due to specific dark matter properties or alternative inflationary models. These deviations […]

Local Description of Decoherence of Quantum Superpositions by Black Holes and Other Bodies

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, , | Summary: It was previously shown that if an experimenter, Alice, puts a massive or charged body in a quantum spatial superposition, then the presence of a black hole (or more generally any Killing horizon) will eventually […]

Exploring the Core-galaxy Connection

Kavli Affiliate: Katrin Heitmann | First 5 Authors: Isabele Souza Vitório, Michael Beuhlmann, Eve Kovacs, Patricia Larsen, Nicholas Frontiere | Summary: Halo core tracking is a novel concept designed to efficiently follow halo substructure in large simulations. We have recently developed this concept in gravity-only simulations to investigate the galaxy-halo connection in the context of […]
