GRB 250424A: A Case Study of Energy Injection with Multiwavelength Observations

Yifang Liang, Yun Wang, WeiKang Zheng +61

We present a comprehensive multiwavelength analysis of the long-duration gamma-ray burst (GRB) 250424A. Our dataset spans from the prompt gamma-ray emission to late-time optical mo…

TDCOSMO XXV: A "soup-to-nuts" 6.5% measurement strong lensing and dynamics with a maximally flexible mass sheet

William Sheu, Tommaso Treu, Martin Millon +16

We present a blind time-delay cosmography measurement of the Hubble constant based on the quadruply imaged quasar SDSSJ1433+6007. Our analysis combines deep Hubble Space Tele…

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…

Cold giant discoveries from a joint radial-velocity and astrometry framework

Pablo A. Peña, James S. Jenkins, Fabo Feng +11

The population of long-period giant planets shapes planetary system architectures and formation pathways, but these cold Jupiters remain relatively unexplored. Radial velocity (RV)…

Time-delay and lens galaxy redshift in the doubly imaged quasar PS J2305+3714

O. A. Burkhonov, V. N. Shalyapin, A. V. Sergeyev +6

We present results from a seven-season (2018-2024) monitoring campaign of the gravitationally lensed quasar system PS J2305+3714 using the 1.5-m Maidanak Telescope in the optical 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…
