Generation of finite groups from subgroups of coprime index

Richie Sater

Let denote the least size of a generating set of a finite group . We prove that if has a family of subgroups such that for every $H\in\mathc…

How to raise a supermassive black hole: interpreting early JWST AGN with the AESOPICA simulations

Sophie Koudmani, Jan Scholtz, Anthony J. Taylor +11

The paper uses the AESOPICA suite of cosmological simulations, varying black hole seed masses and accretion physics, to interpret the abundance and apparent overmassiveness of earl…

Origins of Extreme Emission-Line Ratios in z > 3 Galaxies: Insights from the Lumen Model

Lucie Scharré, Michaela Hirschmann, Adèle Plat +10

Optical emission-line ratios in star-forming galaxies at -8, such as [OIII]/H and [OIII]/[OII], are strongly offset from those at -2, pointing to more extre…

BlackTHUNDER Reveals a Massive Filament around a Compact AGN at

Giulia Tozzi, Hannah Übler, Eleonora Parlanti +27

Despite the growing number of compact active galactic nuclei (AGN) at discovered by JWST, their formation and evolution remain poorly understood. This paper investigates the…

Investigating the star formation histories of galaxies from Cosmic Dawn to the Epoch of Reionization with the Santa Cruz SAM

L. Y. Aaron Yung, Rachel S. Somerville, Steven L. Finkelstein +1

The James Webb Space Telescope (JWST) has opened a new window onto galaxy evolution in the very early Universe. In this work, we leverage halo merger trees extracted from the GUREF…

A Rapid Evolution in the Observed Mbh/M* Relation at z > 3 Revealed via Spectro-photometric SED-Modeling

Ansh R. Gupta, Anthony Taylor, Emma Curtis-Lake +33

Spectroscopic observations from JWST have uncovered a plethora of active galactic nuclei (AGN) at z > 4 with black hole (BH) mass (Mbh) to stellar mass (M*) ratios significantly ab…
