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…
The Cluster HEritage project with XMM-Newton: Mass Assembly and Thermodynamics at the Endpoint of structure formation. I. Programme overview
MATE Collaboration, M. Arnaud, S. Ettori +66
The Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at the Endpoint of structure formation (CHEX-MATE) is a three mega-second Multi-Year Heritage Progra…
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…
Galaxy cluster cores as seen with VLT/MUSE: new strong-lensing analyses of RX J2129.4+0009, MS 0451.6-0305 & MACSJ2129.4-0741
Mathilde Jauzac, Baptiste Klein, Jean-Paul Kneib +4
We present strong-lensing analyses of three galaxy clusters, RXJ2129.4+0009 (z=0.235), MS0451.6-0305 (z=0.55), and MACSJ2129.4-0741 (z=0.589), using the powerful combination of Hub…
On building a cluster watch-list for identifying strongly lensed supernovae, gravitational waves and kilonovae
Dan Ryczanowski, Graham P. Smith, Matteo Bianconi +3
Motivated by discovering strongly-lensed supernovae, gravitational waves, and kilonovae in the 2020s, we investigate whether to build a watch-list of clusters based on observed clu…
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…
hybrid-Lenstool: A self-consistent algorithm to model galaxy clusters with strong- and weak-lensing simultaneously
Anna Niemiec, Mathilde Jauzac, Eric Jullo +5
We present a new galaxy cluster lens modeling approach, hybrid-Lenstool, that is implemented in the publicly available modeling software Lenstool. hybrid-Lenstool combines a parame…
Molecular gas and star formation activity in LIRGs in clusters at intermediate redshifts
G. Castignani, P. Jablonka, F. Combes +10
We investigate the role of dense Mpc-scale environments in processing molecular gas of cluster galaxies as they fall into the cluster cores. We consider luminous infrared…
What does strong gravitational lensing? The mass and redshift distribution of high-magnification lenses
Andrew Robertson, Graham P. Smith, Richard Massey +4
Many distant objects can only be detected, or become more scientifically valuable, if they have been highly magnified by strong gravitational lensing. We use EAGLE and BAHAMAS, two…
