TDCOSMO XXVIII. The Hubble constant from the quadruply lensed quasar J15373010 with precise time delays

A. Galan, A. G. Schweinfurth, S. H. Suyu +21

We present the first measurement of the Hubble constant () from the quadruply-lensed quasar J15373010, which has optically-measured time delays at precision. We…

TDCOSMO. XXIII. Measurement of the Hubble constant from the doubly lensed quasar HE1104-1805

Eric Paic, Frédéric Courbin, Christopher D. Fassnacht +18

Time-delay cosmography leverages strongly lensed quasars to measure the Universe's current expansion rate, H_0, independently from other methods. While the latest TDCOSMO results r…

TDCOSMO 2025: Cosmological constraints from strong lensing time delays

TDCOSMO Collaboration, Simon Birrer, Elizabeth J. Buckley-Geer +30

We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar…

TDCOSMO XVII. New time delays in 22 lensed quasars from optical monitoring with the ESO-VST 2.6m and MPG 2.2m telescopes

Frédéric Dux, Martin Millon, Aymeric Galan +29

We present new time delays, the main ingredient of time delay cosmography, for 22 lensed quasars resulting from high-cadence r-band monitoring on the 2.6 m ESO VLT Survey Telescope…

TDCOSMO. XVI. Measurement of the Hubble Constant from the Lensed Quasar WGD20384008

Kenneth C. Wong, Frédéric Dux, Anowar J. Shajib +17

Time-delay cosmography is a powerful technique to constrain cosmological parameters, particularly the Hubble constant (). The TDCOSMO collaboration is performing an ongoing…

Project Dinos I: A joint lensing-dynamics constraint on the deviation from the power law in the mass profile of massive ellipticals

Chin Yi Tan, Anowar J. Shajib, Simon Birrer +7

The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution. The pow…

Identification of Galaxy-Galaxy Strong Lens Candidates in the DECam Local Volume Exploration Survey Using Machine Learning

E. A. Zaborowski, A. Drlica-Wagner, F. Ashmead +88

We perform a search for galaxy-galaxy strong lens systems using a convolutional neural network (CNN) applied to imaging data from the first public data release of the DECam Local V…

Extreme variability quasars from the Sloan Digital Sky Survey and the Dark Energy Survey

Nick Rumbaugh, Yue Shen, Eric Morganson +49

We perform a systematic search for long-term extreme variability quasars (EVQs) in the overlapping Sloan Digital Sky Survey (SDSS) and 3-Year Dark Energy Survey (DES) imaging, whic…

The 8 o'clock Arc: A Serendipitous Discovery of a Strongly Lensed Lyman Break Galaxy in the SDSS DR4 Imaging Data

Sahar S. Allam, Douglas L. Tucker, Huan Lin +4

We report on the serendipitous discovery of the brightest Lyman Break Galaxy (LBG) currently known, a galaxy at z=2.73 that is being strongly lensed by the z=0.38 Luminous Red Gala…
