High-ionization coronal lines trace quasar-like activity in recently quenched galaxies at high redshift
F. Valentino, K. Ito, M. Farcy +31
We report the detection of the high-ionization line [NeV]3427 in the JWST/NIRSpec archival spectra of 6 massive quenched galaxies at , identified from a parent…
The Journey to Dominance: How BCGs Evolve Differently from Other Massive Galaxies
Marcelo C. Vicentin, Michael A. Strauss, Laerte Sodré +3
We use the L-GALAXIES semi-analytic model to investigate the evolution of Brightest Cluster Galaxies (BCGs) found in clusters at . BCGs are typically located in the c…
The Connection between Dusty Star-Forming Galaxies and the First Massive Quenched Galaxies
Pablo Araya-Araya, Rachel K. Cochrane, Laerte Sodré +6
High-redshift (z > 2) massive quiescent (MQ) galaxies provide an opportunity to probe the key physical processes driving the fuelling and quenching of star formation in the early U…
Galaxy Phase-Space and Field-Level Cosmology: The Strength of Semi-Analytic Models
Natalà S. M. de Santi, Natalí S. M. de Santi, Francisco Villaescusa-Navarro +11
Semi-analytic models are a widely used approach to simulate galaxy properties within a cosmological framework, relying on simplified yet physically motivated prescriptions. They ha…
Selecting Clusters and Protoclusters via Stellar Mass Density: II. Application to HSC-SSP Observations
Marcelo C. Vicentin, Laerte Sodré, Michael A. Strauss +2
We present a selection of candidates of clusters and protoclusters of galaxies identified in the photometric data of the HSC-SSP Wide Public Data Release 3 (PDR3), spanning the red…
Selecting Clusters and Protoclusters via Stellar Mass Density: I. Method and tests on Mock HSC-SSP catalogs
Marcelo C. Vicentin, Pablo Araya-Araya, Laerte Sodré +1
We present an algorithm designed to identify galaxy (proto)clusters in wide-area photometric surveys by first selecting their dominant galaxy-i.e., the Brightest Cluster Galaxy (BC…
