CHEX-MATE: AMALGAM weak-lensing analysis of 41 Planck Sunyaev-Zel'dovich-selected galaxy clusters
Keiichi Umetsu, Raphael Gavazzi, Mauro Sereno +20
We present a weak-lensing shear analysis of 41 Planck SZ-selected galaxy clusters at from the CHEX-MATE sample, using wide-field Subaru/Suprime-Cam and CFHT/Meg…
Globular Clusters in the Galaxy Cluster MACS0416 at z = 0.397
Jessica M. Berkheimer, Rogier A. Windhorst, William E. Harris +27
We present a photometric analysis of globular clusters (GCs) in the massive galaxy cluster MACS J0416.1-2403 (z = 0.397) using deep JWST/NIRCam imaging from the PEARLS program. PSF…
Self-Consistent JWST Census of Star Formation and AGN activity at z=5.5-13.5
Jordan C. J. D'Silva, Simon P. Driver, Claudia D. P. Lagos +24
The cosmic star formation history (CSFH) and cosmic active galactic nuclei (AGN) luminosity history (CAGNH) are self consistently measured at . This is achieved by an…
Galaxy Mergers in the Epoch of Reionization I: A JWST Study of Pair Fractions, Merger Rates, and Stellar Mass Accretion Rates at
Qiao Duan, Christopher J. Conselice, Qiong Li +30
We present a full analysis of galaxy major merger pair fractions, merger rates, and mass accretion rates, thus uncovering the role of mergers in galaxy formation at the earliest pr…
Galaxy populations of ProtoClusters in cosmological hydrodynamical simulations
Michela Esposito, Stefano Borgani, Veronica Strazzullo +6
The study of protoclusters at cosmic noon is essential to understand the impact on galaxies of the environment and of the transformational processes occurring in this epoch. This w…
Galaxy Mergers in the Epoch of Reionization II: Major Merger-Triggered Star Formation and AGN Activities at 4.5-8.5
Qiao Duan, Qiong Li, Christopher J. Conselice +29
Galaxy mergers are a key driver of galaxy formation and evolution, including the triggering of AGN and star formation to a still unknown degree. We thus investigate the impact of g…
