Project Dinos I: A joint lensing-dynamics constraint on the deviation from the power law in the mass profile of massive ellipticals
Chin Yi Tan, Anowar J. Shajib, Simon Birrer +7
The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution. The pow…
Strong lensing by galaxies: past highlights, current status, and future prospects
Anowar J. Shajib
Galaxy-scale strong lensing is a powerful tool in Astrophysics and Cosmology, enabling studies of massive galaxies' internal structure, their formation and evolution, stellar initi…
On the ellipticity parameterization for an NFW profile: an overlooked angular structure in strong lens modeling
Matthew R. Gomer, Dominique Sluse, Lyne Van de Vyvere +3
Galaxy-scale gravitational lenses are often modeled with two-component mass profiles where one component represents the stellar mass and the second is an NFW profile representing t…
Strong Lensing and
Tommaso Treu, Anowar J. Shajib
Time delays from strong gravitational lensing provide a one-step absolute distance measurement. Thus, they measure independently of all other probes. We first review the foun…
Strong lensing selection effects
Alessandro Sonnenfeld, Shun-Sheng Li, Giulia Despali +3
Context. Strong lenses are a biased subset of the general population of galaxies. Aims. The goal of this work is to quantify how lens galaxies and lensed sources differ from their…
TDCOSMO. XII. Improved Hubble constant measurement from lensing time delays using spatially resolved stellar kinematics of the lens galaxy
Anowar J. Shajib, Pritom Mozumdar, Geoff C. -F. Chen +12
Strong-lensing time delays enable measurement of the Hubble constant () independently of other traditional methods. The main limitation to the precision of time-delay cosmog…
