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…

Evaluating Cosmological Biases using Photometric Redshifts for Type Ia Supernova Cosmology with the Dark Energy Survey Supernova Program

R. Chen, D. Scolnic, M. Vincenzi +73

Cosmological analyses with Type Ia Supernovae (SNe Ia) have traditionally been reliant on spectroscopy for both classifying the type of supernova and obtaining reliable redshifts t…

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…
