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…

Further support for a trio of mass-to-light deviations in Abell 370: free-form Grale lens inversion using BUFFALO strong lensing data

Agniva Ghosh, Liliya L. R. Williams, Jori Liesenborgs +9

We use the Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) strong lensing image catalog of the merging galaxy cluster Abell 370 to obtain a mass model using the…

Jellyfish galaxy candidates in MACS J0717.5+3745 and thirty-nine other clusters of the DAFT/FADA and CLASH surveys

Florence Durret, Simon Chiche, Catarina Lobo +1

Galaxies in clusters undergo several phenomena such as ram pressure stripping and tidal interactions, that can trigger or quench their star formation and, in some cases, lead to ga…

Stellar splashback: the edge of the intracluster light

Alis J. Deason, Kyle A. Oman, Azadeh Fattahi +8

We examine the outskirts of galaxy clusters in the C-EAGLE simulations to quantify the `edges' of the stellar and dark matter distribution. The radius of the steepest slope in the…

Reconciling galaxy cluster shapes, measured by theorists vs observers

David Harvey, Andrew Robertson, Sut-Ieng Tam +4

If properly calibrated, the shapes of galaxy clusters can be used to investigate many physical processes: from feedback and quenching of star formation, to the nature of dark matte…

Optical night sky brightness measurements from the stratosphere

Ajay Gill, Steven J. Benton, Anthony M. Brown +27

This paper presents optical night sky brightness measurements from the stratosphere using CCD images taken with the Super-pressure Balloon-borne Imaging Telescope (SuperBIT). The d…
