COSMOS-Web: does halo mass alone shape the clustering of star-forming and quiescent galaxies?

Louise Paquereau, Clotilde Laigle, Henry Joy McCracken +29

While stellar mass correlates strongly with halo mass, it remains unclear whether halo mass alone governs galaxy star-formation activity, or whether secondary halo properties and e…

ASPIRE: The Environments and Dark Matter Halos of Luminous Quasars in the Epoch of Reionization

Feige Wang, Jaclyn B. Champagne, Jiamu Huang +42

We present a systematic study of the environments of 25 luminous quasars at from the ASPIRE program. Using JWST/NIRCam WFSS data, we identified 487 galaxies at $5.3 \less…

The LISA Astrophysics MBHcatalogues Project: A comparison of predictions of simulated massive black hole binaries

David Izquierdo-Villalba, Melanie Habouzit, Matteo Bonetti +67

In the hierarchical paradigm of galaxy formation, central massive black holes (MBHs) are expected to coalesce after the merger of their host galaxies. One of the main goals of the…

The SPHINX public data release. II. Using low-ionisation absorption lines and dust attenuation to predict Lyman continuum escape

Valentin Mauerhofer, Jérémy Blaizot, Thibault Garel +11

Low-ionisation state (LIS) absorption lines, such as SiII 1526, are widely used to trace the properties of the interstellar medium (ISM) in galaxies. These lines provide crucial in…

Before its time: a remarkably evolved protocluster core at z=7.88

Callum Witten, Pascal A. Oesch, William McClymont +11

Protoclusters represent the most extreme environments in the very early Universe. They form from large-scale dark matter overdensities, harbouring an overabundance of galaxies fed…

The Ly and Continuum Origins Survey. III. Investigating the Link between Galaxy Morphology, Merger Properties and LyC Escape

Alexandra Le Reste, Anne E. Jaskot, Jordanne Brazie +20

Characterizing the mechanisms and galaxy properties conducive to the emission and escape of ionizing (LyC) emission is necessary to accurately model the Epoch of Reionization, and…
