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…

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…

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…

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…

Group connectivity in COSMOS: a tracer of mass assembly history

E. Darragh-Ford, C. Laigle, G. Gozaliasl +11

Cosmic filaments are the channel through which galaxy groups assemble their mass. Cosmic connectivity, namely the number of filaments connected to a given group, is therefore expec…

Pre-processing of galaxies in cosmic filaments around AMASCFI clusters in the CFHTLS

Florian Sarron, Christophe Adami, Florence Durret +1

Galaxy clusters and groups are thought to accrete material along the preferred direction of cosmic filaments. Yet these structures have proven difficult to detect due to their low…

Evolution of the cluster optical galaxy luminosity function in the CFHTLS : breaking the degeneracy between mass and redshift

Florian Sarron, Nicolas Martinet, Florence Durret +1

Obtaining large samples of galaxy clusters is important for cosmology, since cluster counts as a function of redshift and mass can constrain the parameters of our Universe. They ar…
