No Evidence for Nearby Circumstellar Material in the Type Ia Supernova 2025rbs
Aravind P. Ravi, Griffin Hosseinzadeh, Stefano Valenti +28
We present a high-resolution spectral time series of the Type Ia supernova (SN) 2025rbs discovered in the nearby galaxy NGC 7331. The Automated Planet Finder (APF) at Lick Observat…
Learning the Universe at High Redshifts: Impact of Accretion Modeling on Early Black Hole Growth
Jonathan Kho, Aklant K. Bhowmick, Rainer Weinberger +8
JWST discoveries of the earliest () supermassive black holes (BHs, ) challenge the BH seeding and accretion models of most cosmol…
Learning the Universe: Constrained simulations of the Coma galaxy cluster -- I. Radial X-ray and Compton-y signatures
Ulrich P. Steinwandel, Stuart McAlpine, Richard Stiskalek +7
We present a suite of 50 high-fidelity simulations of Coma cluster analogues constructed from BORG/MANTICORE constrained initial conditions and evolved with the IllustrisTNG galaxy…
Learning the Universe with PRFM-vol: Introducing a new subgrid model for star formation in cosmological simulations
Jan D. Burger, Volker Springel, Eve C. Ostriker +7
We introduce PRFM-vol, a new subgrid model for star formation in cosmological simulations that aims to increase the physical realism of cosmological simulations by leveraging resul…
AGN Line-Intensity Mapping: A Probe of Faint Black Holes at Cosmic Noon
Eli Visbal, Greg L. Bryan
We propose line-intensity mapping (LIM) as a new probe of active galactic nuclei (AGN). By cross-correlating [Ne V] intensity maps with galaxy redshift surveys, we show that the cu…
Blue Monsters and Dusty Descendants: Reconciling UV and IR Emission from Galaxies from z=7, up to z= 14
Laura Sommovigo, Lachlan Lancaster, Shyam H. Menon +3
Recent JWST observations reveal massive, UV-bright galaxies at with little apparent dust attenuation, whereas ALMA detections at show similarly massive system…
