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…
Superclustering with the Atacama Cosmology Telescope and Dark Energy Survey: II. Anisotropic large-scale coherence in hot gas, galaxies, and dark matter
M. Lokken, A. van Engelen, M. Aguena +73
Statistics that capture the directional dependence of the baryon distribution in the cosmic web enable unique tests of cosmology and astrophysical feedback. We use constrained orie…
Reduction of the type Ia supernova host galaxy step in the outer regions of galaxies
M. Toy, P. Wiseman, M. Sullivan +63
Using 1533 type Ia supernovae (SNe Ia) from the five-year sample of the Dark Energy Survey (DES), we investigate the relationship between the projected galactocentric separation of…
Calibrating the Absolute Magnitude of Type Ia Supernovae in Nearby Galaxies using [OII] and Implications for
M. Dixon, J. Mould, C. Lidman +69
The present state of cosmology is facing a crisis where there is a fundamental disagreement in measurements of the Hubble constant (), with significant tension between the e…
A Pride of Satellites in the Constellation Leo? Discovery of the Leo VI Milky Way Satellite Galaxy with DELVE Early Data Release 3
C. Y. Tan, W. Cerny, A. Drlica-Wagner +32
We report the discovery and spectroscopic confirmation of an ultra-faint Milky Way (MW) satellite in the constellation of Leo. This system was discovered as a spatial overdensity o…
Photometry of outer Solar System objects from the Dark Energy Survey II: a joint analysis of trans-Neptunian absolute magnitudes, colors, lightcurves and dynamics
Pedro H. Bernardinelli, Gary M. Bernstein, T. M. C. Abbott +43
For the 696 trans-Neptunian objects (TNOs) with absolute magnitudes detected in the Dark Energy Survey (DES), we characterize the relationships between their dyna…
