Weak lensing in the blue: a counter-intuitive strategy for stratospheric observations
Mohamed M. Shaaban, Ajay S. Gill, Jacqueline McCleary +24
The statistical power of weak lensing measurements is principally driven by the number of high redshift galaxies whose shapes are resolved. Conventional wisdom and physical intuiti…
Joint HST, VLT/MUSE and XMM-Newton observations to constrain the mass distribution of the two strong lensing galaxy clusters: MACS J0242.5-2132 & MACS J0949.8+1708
Joseph F. V. Allingham, Mathilde Jauzac, David J. Lagattuta +6
We present the strong lensing analysis of two galaxy clusters: MACS J0242.5-2132 (MACS J0242, ) and MACS J0949.8+1708 (MACS J0949, ). Their total matter distribut…
Precision modeling of JWST's first cluster lens SMACSJ0723.3-7327
Guillaume Mahler, Mathilde Jauzac, Johan Richard +12
Exploiting the fundamentally achromatic nature of gravitational lensing, we present a lens model for the massive galaxy cluster SMACSJ0723.3-7323 (SMACSJ0723, z=0.388) that signifi…
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…
Enabling discovery of gravitationally lensed explosive transients: a new method to build an all-sky watch-list of groups and clusters of galaxies
Dan Ryczanowski, Graham P. Smith, Matteo Bianconi +4
Cross-referencing a watchlist of galaxy groups and clusters with transient detections from real-time streams of wide-field survey data is a promising method for discovering gravita…
On the gravitational lensing interpretation of three gravitational wave detections in the mass gap by LIGO and Virgo
Matteo Bianconi, Graham P. Smith, Matt Nicholl +7
We search for gravitational wave (GW) events from LIGO-Virgo's third run that may have been affected by gravitational lensing. Gravitational lensing delays the arrival of GWs, and…
Discovering gravitationally lensed gravitational waves: predicted rates, candidate selection, and localization with the Vera Rubin Observatory
Graham P. Smith, Andrew Robertson, Guillaume Mahler +7
Secure confirmation that a gravitational wave (GW) has been gravitationally lensed would bring together these two pillars of General Relativity for the first time. This breakthroug…
Pilot-WINGS: An extended MUSE view of the structure of Abell 370
David J. Lagattuta, Johan Richard, Franz Erik Bauer +18
We investigate the strong-lensing cluster Abell 370 (A370) using a wide Integral Field Unit (IFU) spectroscopic mosaic from the Multi-Unit Spectroscopic Explorer (MUSE). IFU spectr…
Gravitational lensing effects of supermassive black holes in cluster environments
Guillaume Mahler, Priyamvada Natarajan, Mathilde Jauzac +1
This study explores the gravitational lensing effects of supermassive black holes (SMBHs) in galaxy clusters. While the presence of central SMBHs in galaxies is firmly established,…
Scatter in the satellite galaxy SHMR: fitting functions, scaling relations & physical processes from the IllustrisTNG simulation
Anna Niemiec, Carlo Giocoli, Ethan Cohen +3
The connection between galaxies and their dark matter haloes is often described with the Stellar-to-Halo Mass relation (SHMR). Satellite galaxies in clusters have been shown to fol…
