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…
A song of interactions and mergers: The case of NGC 4709
S. Federle, M. Gómez, S. Mieske +3
Globular clusters (GCs) are fundamental tools to unveil the interaction and merger history of their host galaxies. Our goal is to perform the photometric analysis of the globular c…
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…
Deep learning to improve the discovery of near-Earth asteroids in the Zwicky Transient Facility
Belén Yu Irureta-Goyena, George Helou, Jean-Paul Kneib +7
We present a novel pipeline that uses a convolutional neural network (CNN) to improve the detection capability of near-Earth asteroids (NEAs) in the context of planetary defense. O…
LTDE: The Lens Time Delay Experiment I. From pixels to light curves
Favio Neira, Frédéric Courbin, Frédéric Dux +1
Gravitationally lensed quasars offer a unique opportunity to study cosmological and extragalactic phenomena, using reliable light curves of the lensed images. This requires accurat…
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…
