Introducing the THESAN-ZOOM project: radiation-hydrodynamic simulations of high-redshift galaxies with a multi-phase interstellar medium

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Rahul Kannan, Ewald Puchwein, Aaron Smith, Josh Borrow, Enrico Garaldi | Summary: We introduce the THESAN-ZOOM project, a comprehensive suite of high-resolution zoom-in simulations of $14$ high-redshift ($z>3$) galaxies selected from the THESAN simulation volume. This sample encompasses a diverse range of halo masses, with $M_mathrm{halo} approx […]

Aeos: The Impact of Pop III Initial Mass Function and Star-by-Star Models in Galaxy Simulations

Kavli Affiliate: Anna Frebel | First 5 Authors: Kaley Brauer, Jennifer Mead, John H. Wise, Greg L. Bryan, Mordecai-Mark Mac Low | Summary: We explore the effect of variations in the Population III (Pop III) initial mass function (IMF) and star-by-star feedback on early galaxy formation and evolution using the Aeos simulations. We compare simulations […]

The Massive and Distant Clusters of $WISE$ Survey. XII. Exploring X-ray AGN in Dynamically Active Massive Galaxy Clusters at z~1

Kavli Affiliate: Michael McDonald | First 5 Authors: Mustafa Muhibullah, Mark Brodwin, Michael McDonald, Anthony H. Gonzalez, Emily Moravec | Summary: We present an analysis of the cluster X-ray morphology and active galactic nucleus (AGN) activity in nine $zsim1$ galaxy clusters from the Massive and Distant Clusters of $WISE$ Survey (MaDCoWS) observed with $Chandra$. Using […]

Asteroseismic Study of Subgiants and Giants of the Open Cluster M67 using Kepler/K2: Expanded Sample and Precise Masses

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Claudia Reyes, Dennis Stello, Marc Hon, Yaguang Li, Timothy R. Bedding | Summary: Sparked by the asteroseismic space revolution, ensemble studies have been used to produce empirical relations linking observed seismic properties and fundamental stellar properties. Cluster stars are particularly valuable because they have the same metallicity, […]

TESSELLATE: Piecing Together the Variable Sky With TESS

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Hugh Roxburgh, Ryan Ridden-Harper, Andrew Moore, Clarinda Montilla, Brayden Leicester | Summary: We present TESSELLATE, a dedicated pipeline for performing an untargeted search documenting all variable phenomena captured by the TESS space telescope. Building on the TESSreduce difference imaging pipeline, TESSELLATE extracts calibrated and reduced photometric […]

Are Sparse Autoencoders Useful? A Case Study in Sparse Probing

Kavli Affiliate: Max Tegmark | First 5 Authors: Subhash Kantamneni, Joshua Engels, Senthooran Rajamanoharan, Max Tegmark, Neel Nanda | Summary: Sparse autoencoders (SAEs) are a popular method for interpreting concepts represented in large language model (LLM) activations. However, there is a lack of evidence regarding the validity of their interpretations due to the lack of […]

TOI-6324b: An Earth-Mass Ultra-Short-Period Planet Transiting a Nearby M Dwarf

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Rena A. Lee, Fei Dai, Andrew W. Howard, Samuel Halverson, Jonathan Gomez Barrientos | Summary: We report the confirmation of TOI-6324 b, an Earth-sized (1.059 $pm$ 0.041 R$_oplus$) ultra-short-period (USP) planet orbiting a nearby ($sim$20 pc) M dwarf. Using the newly commissioned Keck Planet Finder (KPF) spectrograph, […]
