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…
Strong lensing time-delay cosmography in the 2020s
T. Treu, S. H. Suyu, P. J. Marshall
Multiply imaged time-variable sources can be used to measure absolute distances as a function of redshifts and thus determine cosmological parameters, chiefly the Hubble Constant H…
Galaxy Spin Classification I: Z-wise vs S-wise Spirals With Chirality Equivariant Residual Network
He Jia, Hong-Ming Zhu, Ue-Li Pen
The angular momentum of galaxies (galaxy spin) contains rich information about the initial condition of the Universe, yet it is challenging to efficiently measure the spin directio…
Gravitational wave fossils in nonlinear regime: halo tidal bias and intrinsic alignments from gravitational wave separate universe simulations
Kazuyuki Akitsu, Yin Li, Teppei Okumura
We investigate impacts of long-wavelength gravitational waves (GWs) on nonlinear structure formation by utilizing the tidal separate universe simulations. Based on the equivalence…
Galaxy clusters at z~1 imaged by ALMA with the Sunyaev-Zel'dovich effect
T. Kitayama, S. Ueda, N. Okabe +15
We present high angular-resolution measurements of the thermal Sunyaev-Zel'dovich effect (SZE) toward two galaxy clusters, RCS J2319+0038 at z=0.9 and HSC J0947-0119 at z=1.1, by t…
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…
HOLISMOKES -- X. Comparison between neural network and semi-automated traditional modeling of strong lenses
S. Schuldt, S. H. Suyu, R. Canameras +4
Modeling of strongly gravitationally lensed galaxies is often required in order to use them as astrophysical or cosmological probes. With current and upcoming wide-field imaging su…
Testing the Collisionless Nature of Dark Matter with the Radial Acceleration Relation in Galaxy Clusters
Sut-Ieng Tam, Keiichi Umetsu, Andrew Robertson +1
The radial acceleration relation (RAR) represents a tight empirical relation between the inferred total and baryonic centripetal accelerations, …
Relativistic distortions in galaxy density-ellipticity correlations: gravitational redshift and peculiar velocity effects
Shohei Saga, Teppei Okumura, Atsushi Taruya +1
We study relativistic effects, arising from the light propagation in an inhomogeneous universe. We particularly investigate the effects imprinted in a cross-correlation function be…
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…
The eROSITA Final Equatorial-Depth Survey (eFEDS): X-ray properties of Subaru optically-selected clusters
N. Ota, N. T. Nguyen-Dang, I. Mitsuishi +17
We present the results of a systematic X-ray analysis of optically rich galaxy clusters detected by the Subaru HSC survey in the eROSITA eFEDS field. Through a joint analysis of SR…
Looking out for the Galileon in the nanohertz gravitational wave sky
Reginald Christian Bernardo, Kin-Wang Ng
We study the polarizations induced by the Galileon as a stochastic gravitational wave background in the cross correlated power in a pulsar timing array. Working within Galileon gra…
Ram pressure stripping in the z~0.5 galaxy cluster MS 0451.6-0305
Florence Durret, Lucie Degott, Catarina. Lobo +3
The pressure exerted by the ambient hot X-ray gas on cluster galaxies can lead to the presence of ram pressure stripped (RPS) galaxies, characterized by asymmetric shapes, and, in…
Line-of-sight Elongation and Hydrostatic Mass Bias of the Frontier Fields Galaxy Cluster Abell 370
Keiichi Umetsu, Shutaro Ueda, Bau-Ching Hsieh +6
We present a detailed weak-lensing and X-ray study of the Frontier Fields galaxy cluster Abell 370, one of the most massive known lenses on the sky, using wide-field BRz Subaru/Spr…
Detection of Cosmological 21 cm Emission with the Canadian Hydrogen Intensity Mapping Experiment
CHIME Collaboration, Mandana Amiri, Kevin Bandura +30
We present a detection of 21-cm emission from large-scale structure (LSS) between redshift 0.78 and 1.43 made with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Radio…

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…
Automated galaxy-galaxy strong lens modelling: no lens left behind
Amy Etherington, James W. Nightingale, Richard Massey +9
The distribution of dark and luminous matter can be mapped around galaxies that gravitationally lens background objects into arcs or Einstein rings. New surveys will soon observe h…
