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: 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…
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…
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…
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…
