LensWatch: I. Resolved HST Observations and Constraints on the Strongly-Lensed Type Ia Supernova 2022qmx ("SN Zwicky")
J. D. R. Pierel, N. Arendse, S. Ertl +39
Supernovae (SNe) that have been multiply-imaged by gravitational lensing are rare and powerful probes for cosmology. Each detection is an opportunity to develop the critical tools…
Time-Delay Cosmography: Measuring the Hubble Constant and other cosmological parameters with strong gravitational lensing
S. Birrer, M. Millon, D. Sluse +5
Multiply lensed sources experience a relative time delay in the arrival of photons. This effect can be used to measure absolute distances and the Hubble constant () and is kno…
Identification of Galaxy-Galaxy Strong Lens Candidates in the DECam Local Volume Exploration Survey Using Machine Learning
E. A. Zaborowski, A. Drlica-Wagner, F. Ashmead +88
We perform a search for galaxy-galaxy strong lens systems using a convolutional neural network (CNN) applied to imaging data from the first public data release of the DECam Local V…
Strong Lensing by Galaxies
A. J. Shajib, G. Vernardos, T. E. Collett +7
Strong gravitational lensing at the galaxy scale is a valuable tool for various applications in astrophysics and cosmology. The primary uses of galaxy-scale lensing are to study el…
TDCOSMO. XI. New lensing galaxy redshift and velocity dispersion measurements from Keck spectroscopy of eight lensed quasar systems
P. Mozumdar, C. D. Fassnacht, T. Treu +2
We have measured the redshifts and single-aperture velocity dispersions of eight lens galaxies using the data collected by the Echellette Spectrograph and Imager (ESI) and Low Reso…
TDCOSMO X. Automated Modeling of 9 Strongly Lensed Quasars and Comparison Between Lens Modeling Software
S. Ertl, S. Schuldt, S. H. Suyu +5
To use strong gravitational lenses as an astrophysical or cosmological probe, models of their mass distributions are often needed. We present a new, time-efficient automation code…
Gravitationally lensed quasars in Gaia -- IV. 150 new lenses, quasar pairs, and projected quasars
C. Lemon, T. Anguita, M. Auger +8
We report the spectroscopic follow-up of 175 lensed quasar candidates selected using Gaia Data Release 2 observations following Lemon et al. 2019. Systems include 86 confirmed lens…
STRIDES: Automated uniform models for 30 quadruply imaged quasars
T. Schmidt, T. Treu, S. Birrer +68
Gravitational time delays provide a powerful one step measurement of , independent of all other probes. One key ingredient in time delay cosmography are high accuracy lens mod…
DeepZipper II: Searching for Lensed Supernovae in Dark Energy Survey Data with Deep Learning
Robert Morgan, B. Nord, K. Bechtol +64
Gravitationally lensed supernovae (LSNe) are important probes of cosmic expansion, but they remain rare and difficult to find. Current cosmic surveys likely contain and 5-10 LSNe i…
LensingETC: a tool to optimize multi-filter imaging campaigns of galaxy-scale strong lensing systems
Anowar J. Shajib, Karl Glazebrook, Tania Barone +7
Imaging data is the principal observable required to use galaxy-scale strong lensing in a multitude of applications in extragalactic astrophysics and cosmology. In this paper, we d…
TDCOSMO. IX. Systematic comparison between lens modelling software programs: time delay prediction for WGD 2038-4008
A. J. Shajib, K. C. Wong, S. Birrer +15
The importance of alternative methods for measuring the Hubble constant, such as time-delay cosmography, is highlighted by the recent Hubble tension. It is paramount to thoroughly…
