Identification of low redshift groups and clusters of galaxies in the X-CLASS survey and the X-ray luminosity-temperature relation
Q. Moysan, F. Sarron, N. Clerc +16
Properties of the hot intracluster and intragroup medium are mostly set by the underlying gravitational potential well, although complex astrophysical processes at play during thei…
Euclid preparation. 3D reconstruction of the cosmic web with simulated Euclid Deep spectroscopic samples
Euclid Collaboration, K. Kraljic, C. Laigle +321
The ongoing Euclid mission aims to measure spectroscopic redshifts for approximately two million galaxies using the H line emission detected in near-infrared slitless spectrosc…
Galaxy groups in various evolutionary stages
Kethelin Parra Ramos, C. Adami, N. Clerc +10
The formation process of galaxy groups is not yet fully understood. In particular, that of fossil groups (FGs) is still under debate. Due to the relative rarity of FGs, large sampl…
Euclid preparation. Establishing the quality of the 2D reconstruction of the filaments of the cosmic web with DisPerSE using Euclid photometric redshifts
Euclid Collaboration, N. Malavasi, F. Sarron +313
Cosmic filaments are prominent structures of the matter distribution of the Universe. Modern detection algorithms are an efficient way to identify filaments in large-scale observat…
Distinct origins of environmentally quenched galaxies in the core and outer virialised regions of massive clusters at
Guillaume Hewitt, Florian Sarron, Michael L. Balogh +15
High-redshift () galaxy clusters are the domain where environmental quenching mechanisms are expected to emerge as important factors in the evolution of the quiescent galax…
Euclid Quick Data Release (Q1). Galaxy shapes and alignments in the cosmic web
Euclid Collaboration, C. Laigle, C. Gouin +341
Galaxy morphologies and shape orientations are expected to correlate with their large-scale environment, since they grow by accreting matter from the cosmic web and are subject to…
Euclid Quick Data Release (Q1). The first Euclid view of Planck galaxy protocluster candidates at cosmic noon
Euclid Collaboration, T. Dusserre, H. Dole +339
[ABRIGED ABSTRACT] A large catalogue of candidate galaxy protoclusters with high star-formation rates was produced by the Planck collaboration. We search, in the first data release…
Euclid Quick Data Release (Q1). The role of cosmic connectivity in shaping galaxy clusters
Euclid Collaboration, C. Gouin, C. Laigle +337
The matter distribution around galaxy clusters is distributed over several filaments, reflecting their positions as nodes in the large-scale cosmic web. The number of filaments con…
EPOCHS Paper X: Environmental effects on Galaxy Formation and Protocluster Galaxy candidates at from JWST observations
Qiong Li, Christopher J. Conselice, Florian Sarron +16
In this paper we describe our search for galaxy protocluster candidates at and explore the environmental and physical properties of their member galaxies identified t…
When the Well Runs Dry: Modeling Environmental Quenching of High-mass Satellites in Massive Clusters at \boldmath
Devontae C. Baxter, Michael C. Cooper, Michael L. Balogh +11
We explore models of massive () satellite quenching in massive clusters at using an MCMC framework, focusing on two primary parameters: $R_…
A UNIONS view of the brightest central galaxies of candidate fossil groups
Aline Chu, F. Durret, A. Ellien +10
The formation process of fossil groups (FGs) is still under debate, and large samples of such objects are still missing. The aim of this paper is to increase the sample of known FG…
GOGREEN: a critical assessment of environmental trends in cosmological hydrodynamical simulations at z ~ 1
Egidijus Kukstas, Michael L. Balogh, Ian G. McCarthy +28
Recent observations have shown that the environmental quenching of galaxies at z ~ 1 is qualitatively different to that in the local Universe. However, the physical origin of these…
The GOGREEN Survey: Constraining the Satellite Quenching Timescale in Massive Clusters at
Devontae Baxter, Michael Cooper, Michael Balogh +15
We model satellite quenching at by combining massive () clusters at from the GOGREEN and…
Physical properties of more than one thousand brightest cluster galaxies detected in the Canada France Hawaii Telescope Legacy Survey
Aline Chu, Florian Sarron, Florence Durret +1
Brightest cluster galaxies (BCGs) are very massive elliptical galaxies found at the centers of clusters. Their study gives clues on the formation and evolution of the clusters in w…
DETECTIFz galaxy groups in the REFINE survey -- 1. Group detection and quenched fraction evolution at
Florian Sarron, Christopher J Conselice
We use a large K-selected sample of 299,961 galaxies from the REFINE survey, consisting of a combination of data from three of the deepest near-infrared surveys: UKIDSS UDS, COSMOS…
Candidate fossil groups in the CFHTLS: a probabilistic approach
C. Adami, F. Sarron, N. Martinet +1
Fossil groups (FGs) have been discovered twenty-five years ago, and are now defined as galaxy groups with an X-ray luminosity higher than erg s and a…
Mapping and characterisation of cosmic filaments in galaxy cluster outskirts: strategies and forecasts for observations from simulations
Ulrike Kuchner, Alfonso Aragón-Salamanca, Frazer R. Pearce +11
Upcoming wide-field surveys are well-suited to studying the growth of galaxy clusters by tracing galaxy and gas accretion along cosmic filaments. We use hydrodynamic simulations of…
Euclid preparation III. Galaxy cluster detection in the wide photometric survey, performance and algorithm selection
