Dark Energy Survey: Galaxy Sample for the Baryonic Acoustic Oscillation Measurement from the Final Dataset

J. Mena-Fernández, M. Rodríguez-Monroy, S. Avila +85

In this paper we present and validate the galaxy sample used for the analysis of the baryon acoustic oscillation (BAO) signal in the Dark Energy Survey (DES) Y6 data. The definitio…

The Dark Energy Survey: Cosmology Results With ~1500 New High-redshift Type Ia Supernovae Using The Full 5-year Dataset

DES Collaboration, T. M. C. Abbott, M. Acevedo +156

We present cosmological constraints from the sample of Type Ia supernovae (SN Ia) discovered during the full five years of the Dark Energy Survey (DES) Supernova Program. In contra…

Deep inference of simulated strong lenses in ground-based surveys

Jason Poh, Ashwin Samudre, Aleksandra Ćiprijanović +3

The large number of strong lenses discoverable in future astronomical surveys will likely enhance the value of strong gravitational lensing as a cosmic probe of dark energy and dar…

High-Significance Detection of Correlation Between the Unresolved Gamma-Ray Background and the Large Scale Cosmic Structure

B. Thakore, M. Negro, M. Regis +96

Our understanding of the -ray sky has improved dramatically in the past decade, however, the unresolved -ray background (UGRB) still has a potential wealth of information a…

The Effect of Nonlinear Gravity on the Cosmological Background During Preheating

Ryn Grutkoski, Hayley J. Macpherson, John T. Giblin +1

We use numerical relativity to study the violent preheating era at the end of inflation. This epoch can result in highly nonlinear fluctuations in density and gravitational potenti…
