The abundance and nature of high-redshift quiescent galaxies from JADES spectroscopy and the FLAMINGO simulations

Kavli Affiliate: Roberto Maiolino | First 5 Authors: William M. Baker, Seunghwan Lim, Francesco D’Eugenio, Roberto Maiolino, Zhiyuan Ji | Summary: We use NIRSpec/MSA spectroscopy and NIRCam imaging to study a sample of 18 massive ($log; M_{*}/M_{odot} gt 10;$dex), central quiescent galaxies at $2leq z leq 5$ in the GOODS fields, to investigate their number […]

Decomposing The Dark Matter of Sparse Autoencoders

Kavli Affiliate: Max Tegmark | First 5 Authors: Joshua Engels, Logan Riggs, Max Tegmark, , | Summary: Sparse autoencoders (SAEs) are a promising technique for decomposing language model activations into interpretable linear features. However, current SAEs fall short of completely explaining model performance, resulting in "dark matter": unexplained variance in activations. This work investigates dark […]

A diverse, overlooked population of Type Ia supernovae exhibiting mid-infrared signatures of delayed circumstellar interaction

Kavli Affiliate: Nathan P. Lourie | First 5 Authors: Geoffrey Mo, Kishalay De, Eli Wiston, Nayana A. J., Raffaella Margutti | Summary: Type Ia supernovae arise from the thermonuclear explosions of white dwarfs in multiple star systems. A rare sub-class of SNe Ia exhibit signatures of interaction with circumstellar material (CSM), allowing for direct constraints […]
