Unsupervised Tool Evolution for Coding Agents in Data-Lake Analytics

Yuqing Yang, Yurong Liu, Deqing Fu +5

Coding agents can answer analytical questions over a data lake by discovering, cleaning, and joining the relevant data. However, they discard this work after each question and redo…

Supernovae Unite: Host-Galaxy Mass Measurements of Type Ia Supernovae and Their Impact on Cosmology

J. Lee, R. Camilleri, T. M. Davis +22

Current consensus suggests that Type Ia supernova (SN Ia) brightnesses post light-curve standardization correlate with their host-galaxy stellar masses, which must be accounted for…

Constraints on Dynamical Dark Energy from Multiple Probes in the Full Dark Energy Survey

DES Collaboration, T. M. C. Abbott, M. Adamow +166

We present results on dark energy evolution, assuming a time-dependent equation of state , from growth and geometric probes using the full six-year Dark Energy S…

Challenges to the cosmological constant model following results from the Dark Energy Survey

Santiago Avila, Juan Mena-Fernández, Maria Vincenzi

In the last year, several pieces of evidence have pointed to a possible deviation from the standard cosmological model, CDM. The recent work by the Dark Energy Survey (DES) coll…

Applications of 1.4 GHz diagnostics to Type Ia Supernova host galaxies

S. Ramaiya, M. J. Jarvis, M. Vincenzi +2

Type Ia supernova (SN Ia) standardisation parameters exhibit evidence for systematic variation across the host galaxy star-formation rate - stellar mass (SFR) plane, moti…

Calibration-Induced Systematics in SALT3 Training and Their Impact on Dark Energy Constraints from Stage IV Supernova Surveys

Kene Anumba, David O. Jones, Richard Kessler +13

In the coming years, the Vera Rubin Observatory's Legacy Survey of Space and Time (Rubin-LSST) and the Nancy Grace Roman Space Telescope's (Roman) High Latitude Time Domain Survey…

Old Universe, Young SNe Ia: A Statistical Analysis of Type Ia Supernova Progenitor Age from 6,983 TITAN Host Galaxies, and Implications for Cosmology

Yukei Murakami, Jack Tweddle, Phil Wiseman +17

Correlations between standardized Type Ia supernova (SN Ia) luminosities and host-galaxy properties are routinely modeled to avoid bias in cosmological parameter inference. A recen…

Dark Energy Survey Year 6 Results: Cosmological Constraints from Cosmic Shear

DES Collaboration, T. M. C. Abbott, M. Aguena +126

We present legacy cosmic shear measurements and cosmological constraints using six years of Dark Energy Survey imaging data. From these data, we study ~140 million galaxies (8.29 g…

Dark Energy Survey Year 6 Results: Galaxy-galaxy lensing

G. Giannini, G. Camacho-Ciurana, A. Whyley +116

We present galaxy--galaxy lensing (GGL) measurements from the full six years of data from the Dark Energy Survey (DES Y6), covering and used in the DES Y6 $3…

Dark Energy Survey: DESI-Independent Angular BAO Measurement

J. Mena-Fernández, S. Avila, A. Porredon +80

We present a measurement of the angular baryon acoustic oscillation (BAO) scale from the completed Dark Energy Survey (DES) dataset excluding the area of overlap with the Dark Ener…

Still Accelerating: Type Ia supernova cosmology is robust to host galaxy age evolution

Phil Wiseman, Brodie Popovic, Mark Sullivan +14

Type Ia supernovae are a cornerstone of modern cosmology, providing first evidence for cosmic acceleration and new tests of dark energy. Son et al. 2025 (S25) claim a strong redshi…
