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…
TDCOSMO XXX: Spatially resolved kinematics of the deflectors in time-delay lens systems B1608+656 and SDSSJ1206+4332 from JWST-NIRSpec observation
Pritom Mozumdar, Shawn Knabel, Anowar J. Shajib +3
We present spatially resolved stellar kinematics of the deflector galaxies in two time-delay lens systems, B1608+656 and SDSS J1206+4332, measured from JWST NIRSpec integral field…
TDCOSMO XXIX: JWST/NIRSpec IFU Spatially Resolved Kinematics of Three Time-delay Lenses
Shawn Knabel, Pritom Mozumdar, Anowar J. Shajib +8
Spatially resolved stellar kinematics are critical to the high precision achieved by cosmological probes utilizing time delays of strongly lensed quasars. Combined with high-resolu…
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. XXVII. JWST-based Lens Models and H Measurement of WFI2033, HE0435, and PG1115
D. M. Williams, T. Treu, D. P. Johnson +13
Time-delay cosmography offers a one-step, distance-ladder-independent route to the Hubble-Lemaitre constant, H_0. We present new cosmography-grade lens models of three quadruply im…
Supermassive black holes in six triaxial galaxies: Insights from SINFONI and MUSE observations
Sabine Thater, Avinash Chaturvedi, Davor Krajnovic +5
Dynamical modelling can be used to constrain the masses of central black holes; however, modelling massive galaxies is challenging due to their complexity. In this work, we report…
TDCOSMO XXV: Measuring H0 to 6.5% precision with quasar strong lensing and maximally flexible mass-sheet dynamics
William Sheu, Tommaso Treu, Martin Millon +16
We present a blind time-delay cosmography measurement of the Hubble-Lemaître constant based on the quadruply imaged quasar SDSSJ1433+6007. Our analysis combines deep Hubble S…
Spatially Resolved Kinematics of SLACS Lens Galaxies. II: Breaking Degeneracies with Lensing and Dynamical Models
Shawn Knabel, Tommaso Treu, Michele Cappellari +4
We model the dynamical mass density profiles of 14 strong gravitational lens galaxies from the Sloan Lens ACS (SLACS) sample using spatially resolved kinematics obtained from Keck…
WISDOM Project -- XXVIII. Molecular gas measurement of the supermassive black hole mass of the galaxy NGC 1387
Pandora Dominiak, Martin Bureau, Fu-Heng Liang +6
Supermassive black hole (SMBH) masses can be measured using molecular gas kinematics. Here we present high angular resolution ( arcsec or pc) Atacama Large Millim…
A general spectral solver for the axisymmetric Jeans equations: fast dynamical modelling of galaxies with arbitrary anisotropy
Michele Cappellari
Axisymmetric Jeans modelling is widely used to infer galaxy mass profiles from integral-field kinematics, but existing implementations maintain tractability by adopting highly rest…
MAGNUS III: Mild evolution of the total density slope in massive early-type galaxies since z1 from dynamical modeling of MUSE integral-field stellar kinematics
Pritom Mozumdar, Michele Cappellari, Christopher D. Fassnacht +1
We investigate the total mass density slope evolution in massive early-type galaxies (ETGs) over the last 6.5 billion years (). We perform a detailed dynamical analys…
