Constraints on compact objects from the Dark Energy Survey five-year supernova sample

Paul Shah, Tamara M. Davis, Maria Vincenzi +57

Gravitational lensing magnification of Type Ia supernovae (SNe Ia) allows information to be obtained about the distribution of matter on small scales. In this paper, we derive limi…

Interacting Dark Sector (ETHOS ): Cosmological Constraints from SPT Cluster Abundance with DES and HST Weak Lensing Data

A. Mazoun, S. Bocquet, J. J. Mohr +64

We use galaxy cluster abundance measurements from the South Pole Telescope (SPT) enhanced by Multi-Component Matched Filter (MCMF) confirmation and complemented with mass informati…

Dark Energy Survey Year 3: Blue Shear

J. McCullough, A. Amon, E. Legnani +115

Modeling the intrinsic alignment (IA) of galaxies poses a challenge to weak lensing analyses. The Dark Energy Survey is expected to be less impacted by IA when limited to blue, sta…

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…

The Hierarchical Growth of Bright Central Galaxies and Intracluster Light as Traced by the Magnitude Gap

Jesse B. Golden-Marx, Y. Zhang, R. L. C. Ogando +48

Using a sample of 2800 galaxy clusters identified in the Dark Energy Survey across the redshift range , we characterize the hierarchical assembly of Bright Central…

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…

Weak Gravitational Lensing around Low Surface Brightness Galaxies in the DES Year 3 Data

N. Chicoine, J. Prat, G. Zacharegkas +102

We present galaxy-galaxy lensing measurements using a sample of low surface brightness galaxies (LSBGs) drawn from the Dark Energy Survey Year 3 (Y3) data as lenses. LSBGs are diff…

Galaxy cluster matter profiles: I. Self-similarity, mass calibration, and observable-mass relation validation employing cluster mass posteriors

A. Singh, J. J. Mohr, C. T. Davies +50

We present a study of the weak lensing inferred matter profiles of 698 South Pole Telescope thermal Sunyaev-Zel'dovich effect selected and MCMF optically confirmed galaxy c…

Modelling the impact of host galaxy dust on type Ia supernova distance measurements

B. Popovic, P. Wiseman, M. Sullivan +65

Type Ia Supernovae (SNe Ia) are a critical tool in measuring the accelerating expansion of the universe. Recent efforts to improve these standard candles have focused on incorporat…

The Dark Energy Survey Supernova Program: An updated measurement of the Hubble constant using the Inverse Distance Ladder

R. Camilleri, T. M. Davis, S. R. Hinton +77

We measure the current expansion rate of the Universe, Hubble's constant , by calibrating the absolute magnitudes of supernovae to distances measured by Baryon Acoustic Oscill…

The Dark Energy Survey Supernova Program: Light curves and 5-Year data release

B. O. Sánchez, D. Brout, M. Vincenzi +82

We present photometric light curves for the full 5 years of the Dark Energy Survey Supernova program (DES-SN), obtained with both forced Point Spread Function (PSF) photomet…

The Dark Energy Survey Supernova Program: Slow supernovae show cosmological time dilation out to

R. M. T. White, T. M. Davis, G. F. Lewis +67

We present a precise measurement of cosmological time dilation using the light curves of 1504 type Ia supernovae from the Dark Energy Survey spanning a redshift range $0.1\lesssim…

The Dark Energy Survey Supernova Program: Investigating Beyond-CDM

R. Camilleri, T. M. Davis, M. Vincenzi +77

We report constraints on a variety of non-standard cosmological models using the full 5-year photometrically-classified type Ia supernova sample from the Dark Energy Survey (DES-SN…

The Dark Energy Survey 5-year photometrically classified type Ia supernovae without host-galaxy redshifts

A. Möller, P. Wiseman, M. Smith +60

Current and future Type Ia Supernova (SN Ia) surveys will need to adopt new approaches to classifying SNe and obtaining their redshifts without spectra if they wish to reach their…
