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 s…

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…

Galaxy Phase-Space and Field-Level Cosmology: The Strength of Semi-Analytic Models

Natalí S. M. de Santi, Francisco Villaescusa-Navarro, Pablo Araya-Araya +8

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: 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…

A large thermal energy reservoir in the nascent intracluster medium at a redshift of 4.3

Dazhi Zhou, Scott Chapman, Manuel Aravena +21

Most baryons in present-day galaxy clusters exist as hot gas (), forming the intracluster medium (ICM). Cosmological simulations predict th…

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…

Simultaneously Modelling Dusty Star Forming Galaxies and Massive Quiescents: A Calibration Framework for Galaxy Formation Models

Pablo Araya-Araya, Rachel K. Cochrane, Christopher C. Hayward +4

Galaxy formation models, particularly semi-analytic models (SAMs), rely on differential equations with free parameters to describe the physical mechanisms governing galaxy formatio…

Modelling the multi-wavelength detection of protoclusters. I: An excess of submillimetre galaxies in protocluster cores

Pablo Araya-Araya, Rachel K. Cochrane, Christopher C. Hayward +6

Studies of galaxy protoclusters yield insights into galaxy cluster formation complementary to those obtained via `archaeological' studies of present-day galaxy clusters. Submillime…
