TDCOSMO 2026: new insights on the Hubble tension from strong lensing time delays
TDCOSMO Collaboration, Simon Birrer, Michele Cappellari +26
We discuss the measurement of the Hubble constant () in flat cold dark matter cosmology based on the blind hierarchical analysis of 11 multiply-imaged quasars (hereafter t…
TDCOSMO 2026: A 3% measurement of the Hubble constant from strong lensing and stellar kinematics
TDCOSMO Collaboration, Simon Birrer, Michele Cappellari +26
We present cosmological constraints from 11 strongly lensed quasars with measured time delays (hereafter, the TDCOSMO-2026 sample). In addition to expanding the sample, we improve…
Possible Detection of Cosmological Reionization Sources
M. Stiavelli, S. M. Fall, N. Panagia
We compare the available catalogs of galaxies in the Hubble Ultra-Deep Field (UDF) and in the Great Observatories Origins Deep Survey (GOODS) with the expected properti…
Violent Relaxation Around a Massive Black Hole
M. Stiavelli
I present galaxy models resulting from violent relaxation in the presence of a pre-existing black hole. The models are computed by maximizing the entropy of the stellar dynamical s…
