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…
The distribution of dark matter and gas spanning six megaparsecs around the post-merger galaxy cluster MS0451-03
Sut-Ieng Tam, Mathilde Jauzac, Richard Massey +11
Using the largest mosaic of Hubble Space Telescope images around a galaxy cluster, we map the distribution of dark matter throughout a Mpc area centred on the…
Mapping dark matter and finding filaments: calibration of lensing analysis techniques on simulated data
Sut-Ieng Tam, Richard Massey, Mathilde Jauzac +1
We quantify the performance of mass mapping techniques on mock imaging and gravitational lensing data of galaxy clusters. The optimum method depends upon the scientific goal. We as…
Download by Parachute: Retrieval of Assets from High Altitude Balloons
E. L. Sirks, P. Clark, R. J. Massey +27
We present a publicly-available toolkit of flight-proven hardware and software to retrieve 5 TB of data or small physical samples from a stratospheric balloon platform. Before laun…
The BUFFALO HST Survey
Charles L. Steinhardt, Mathilde Jauzac, Ana Acebron +91
The Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) is a 101 orbit + 101 parallel Cycle 25 Hubble Space Telescope Treasury program taking data from 2018-2020. B…
