TDCOSMO XXVI: Uniform lens modeling of eight doubly imaged quasars
Ryan Brady, Xiang-Yu Huang, Simon Birrer +7
We present the first uniform gravitational lens modeling analysis of eight doubly imaged quasars from multi-band observations with the Hubble Space Telescope. Previous time-delay c…
On combining estimated and analytic covariance matrices
Alan Heavens, Lorne Whiteway, Elena Sellentin
The statistical analysis of cosmological data often assumes a Gaussian sampling distribution and relies on covariance matrices estimated from simulations. In this setting, the like…
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…
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…
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…
Investigating the Dark Energy Constraint from Strongly Lensed AGN at LSST-Scale
Sydney Erickson, Martin Millon, Padmavathi Venkatraman +12
Strongly lensed Active Galactic Nuclei (AGN) with an observable time delay can be used to constrain the expansion history of the Universe through time-delay cosmography (TDC). As t…
