Intracluster light in the infall region of simulated protoclusters of galaxies
S. V. Werner, M. Jauzac, M. Montes +4
Intracluster light (ICL) is a diffuse stellar component in galaxy clusters, made of stars following the potential of the cluster. Despite its potential to unveil the accretion hist…
A comprehensive separation of dark matter and baryonic mass components in galaxy clusters I: Mass constraints from Abell S1063
Benjamin Beauchesne, Benjamin Clément, Marceau Limousin +11
In this two-part series, we present a multi-probe mass modelling method for massive galaxy clusters, designed to disentangle the contributions of individual mass components (Dark m…
Identification of 40 gravitationally magnified stars in a galaxy at redshift of 0.725
Yoshinobu Fudamoto, Fengwu Sun, Jose M. Diego +44
Strong gravitational magnifications enable to detect faint background sources, resolve their internal structures, and even identify individual stars in distant galaxies. Highly mag…
A complex node of the cosmic web associated with the massive galaxy cluster MACS J0600.1-2008
Lukas J. Furtak, Adi Zitrin, Johan P. Richard +18
MACS J0600.1-2008 (MACS0600) is an X-ray luminous, massive galaxy cluster at , studied previously by the REionization LensIng Cluster Survey (RELICS) and ALMA…
BUFFALO/Flashlights: Constraints on the abundance of lensed supergiant stars in the Spock galaxy at redshift 1
Jose M. Diego, Sung Kei Li, Ashish K. Meena +27
We present a constraint on the abundance of supergiant (SG) stars at redshift z approx. 1, based on recent observations of a strongly lensed arc at this redshift. First we derive a…
The impact of human expert visual inspection on the discovery of strong gravitational lenses
Karina Rojas, Thomas E. Collett, Daniel Ballard +53
We investigate the ability of human 'expert' classifiers to identify strong gravitational lens candidates in Dark Energy Survey like imaging. We recruited a total of 55 people that…
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…
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…
Dark matter stripping in galaxy clusters: a look at the Stellar to Halo Mass relation in the Illustris simulation
Anna Niemiec, Eric Jullo, Carlo Giocoli +2
Satellite galaxies in galaxy clusters represent a significant fraction of the global galaxy population. Because of the unusual dense environment of clusters, their evolution is dri…
Observational evidence of galaxy assembly bias
Antonio D. Montero-Dorta, Enrique Perez, Francisco Prada +10
We analyze the spectra of 300,000 luminous red galaxies (LRGs) with stellar masses from the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS).…
