ACACIAS I: Element abundance labels for 192 stars in the dwarf galaxy NGC 6822

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Melissa K. Ness, J. Trevor Mendel, Sven Buder, Adam Wheeler, Alexander P. Ji | Summary: The element abundances of local group galaxies connect enrichment mechanisms to galactic properties and serve to contextualise the Milky Way’s abundance distributions. Individual stellar spectra in nearby galaxies can be extracted […]

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 […]
