AI Scientists as Engines of Discovery: A Case for Development within Reformed Institutions
Raul Jimenez, Boris Bolliet, Francisco Villaescusa-Navarro +7
Agentic artificial intelligence (AI) systems are beginning to assist, accelerate, and partially automate scientific discovery, performing tasks that span literature synthesis, code…
From Evidence to Evident: Decisive Cosmological Evidence for the Normal Neutrino Mass Hierarchy
Raul Jimenez, Carlos Peña Garay, Fergus Simpson +1
Cosmological data have reached the precision needed to turn the neutrino mass ordering from a weak Bayesian preference into a decisive model-selection test. We compute the evidence…
The Coherence Principle: A Falsifiable Prior for Model Selection from the Grammar of Theories
Raul Jimenez, Carlos Peña Garay, Fergus Simpson +1
Bayesian model selection in cosmology and particle physics is often performed where posterior odds inherit a strong, often unacknowledged dependence on the prior assigned to compet…
The Age of the Universe with Globular Clusters IV: Multiple Stellar Populations
David Valcin, Raul Jimenez, Carmela Lardo +2
We revisit the determination of the age of the Universe from galactic globular clusters, extending previous analyses by explicitly accounting for the presence of multiple stellar p…
The Atacama Cosmology Telescope: Constraints on Local Non-Gaussianity from the ACT Cluster Catalog
Leonid Sarieddine, J. Richard Bond, Matt Hilton +8
We derive constraints on local-type primordial non-Gaussianity using the ACT DR6 Sunyaev--Zel'dovich cluster catalog. Modeling the redshift- and mass-dependent number counts of 1,2…
Cosmic Chronometers: Constraining the Equation of State of Dark Energy. II. A Spectroscopic Catalog of Red Galaxies in Galaxy Clusters
Daniel Stern, Raul Jimenez, Licia Verde +2
We present a spectroscopic catalog of (mostly) red galaxies in 24 galaxy clusters in the redshift range 0.17 < z < 0.92 obtained with the LRIS instrument on the Keck I telescope. H…
Cosmic Chronometers: Constraining the Equation of State of Dark Energy. I: H(z) Measurements
Daniel Stern, Raul Jimenez, Licia Verde +2
We present new determinations of the cosmic expansion history from red-envelope galaxies. We have obtained for this purpose high-quality spectra with the Keck-LRIS spectrograph of…
