Investigating the Dark Energy Constraint from Strongly Lensed AGN at LSST-Scale
Sydney Erickson, Martin Millon, Padmavathi Venkatraman +12
The paper presents a scalable hierarchical inference framework to jointly analyze hundreds of strongly lensed AGN time delays from LSST, forecasting a ~2.5% measurement of H0 and a…
On combining estimated and analytic covariance matrices
Alan Heavens, Lorne Whiteway, Elena Sellentin
The paper derives an accurate multivariate Student‑t approximation for likelihoods that combine covariance matrices estimated from simulations with additional Gaussian error contri…
Characterization of the Polarization Beam Response of SPT-3G Using Point Sources
T. de Haan, M. Archipley, N. Huang +101
Precise measurements of cosmic microwave background (CMB) polarization require rigorous control of instrumental systematics. For the South Pole Telescope's third-generation camera…
Joint cosmological fits to DESI-DR1 full-shape clustering and weak gravitational lensing in configuration space
A. Semenaite, C. Blake, A. Porredon +69
We present a joint -pt cosmological analysis of auto- and cross-correlations between the Dark Energy Spectroscopic Instrument Data Release 1 (DESI-DR1) Bright Galaxy Surv…
Probing Dark Energy Microphysics with kSZ Tomography
Julius Adolff, Selim Hotinli, Neal Dalal
The accelerated expansion of the Universe is well established by geometric probes, yet its physical origin remains poorly understood. Most constraints on dark energy arise from bac…
Evolving and interacting dark energy: photometric and spectroscopic synergy with DES Y3 and DESI DR2
M. Tsedrik, B. Bose
We investigate the Dark Scattering (DS) interacting dark energy scenario, characterised by pure momentum exchange between dark matter and dark energy, combined with a time-dependen…
