University of Hawaii 88-inch Telescope Observations of the Interstellar Comet 3I/ATLAS: Spectrophotometric Blue-Sensitive Spectral Time Series Spanning Two Months from Discovery
W. B. Hoogendam, D. Kuesters, B. J. Shappee +22
The paper presents blue‑sensitive spectrophotometric observations of the interstellar comet 3I/ATLAS over two months, reporting its early UV spectrum, variable spectral slopes, com…
Investigating the Dark Energy Constraint from Strongly Lensed AGN at LSST-Scale
Sydney Erickson, Martin Millon, Padmavathi Venkatraman +12
The paper presents a scalable hierarchical inference framework to jointly analyze hundreds of strongly lensed AGN time delays from LSST, forecasting a ~2.5% measurement of H0 and a…
On combining estimated and analytic covariance matrices
Alan Heavens, Lorne Whiteway, Elena Sellentin
The paper derives an accurate multivariate Student‑t approximation for likelihoods that combine covariance matrices estimated from simulations with additional Gaussian error contri…
Idealized Global Models of Accretion Disks with Strong Toroidal Magnetic Fields
Minghao Guo, Eliot Quataert, Jonathan Squire +2
We present global magnetohydrodynamic (MHD) simulations of idealized accretion disks with a strong toroidal magnetic field using an equation of state that fixes the gas thermal sca…
Interpretable machine learning of halo gas density profiles: a sensitivity analysis of cosmological hydrodynamical simulations
Daniele Sorini, Sownak Bose, Mathilda Denison +1
Stellar and AGN-driven feedback processes affect the distribution of gas on a wide range of scales, from within galaxies well into the intergalactic medium. Yet, it remains unclear…
Black Hole Feedback, Galaxy Quenching and Outflows at Cosmic Dawn: Analysis of the SEEDZ Simulations
Lewis R. Prole, John A. Regan, Daxal Mehta +13
Here we analyse the growth and feedback effects of massive black holes (MBHs) in the SEEDZ simulations. The most massive black holes grow to masses of M by $z=…
