The Dark Energy Survey Supernova Program: Cosmological Biases from Host Galaxy Mismatch of Type Ia Supernovae
H. Qu, M. Sako, M. Vincenzi +58
Redshift measurements, primarily obtained from host galaxies, are essential for inferring cosmological parameters from type Ia supernovae (SNe Ia). Matching SNe to host galaxies us…
The Dark Energy Survey Supernova Program: Corrections on photometry due to wavelength-dependent atmospheric effects
J. Lee, M. Acevedo, M. Sako +64
Wavelength-dependent atmospheric effects impact photometric supernova flux measurements for ground-based observations. We present corrections on supernova flux measurements from th…
Multiwavelength observations of the extraordinary accretion event AT2021lwx
P. Wiseman, Y. Wang, S. Hönig +43
We present observations from X-ray to mid-infrared wavelengths of the most energetic non-quasar transient ever observed, AT2021lwx. Our data show a single optical brightening by a…
Further evidence that galaxy age drives observed type Ia supernova luminosity differences
P. Wiseman, M. Sullivan, M. Smith +1
Type Ia supernovae (SNe Ia) are explosions of white dwarf stars that facilitate exquisite measurements of cosmological expansion history, but improvements in accuracy and precision…
Rates and properties of type Ia supernovae in galaxy clusters within the Dark Energy Survey
M. Toy, P. Wiseman, M. Sullivan +59
We identify 66 photometrically classified type Ia supernovae (SNe Ia) from the Dark Energy Survey (DES) that have occurred within red-sequence selected galaxy clusters. We compare…
A Sample of Dust Attenuation Laws for DES Supernova Host Galaxies
J. Duarte, S. González-Gaitán, A. Mourao +58
Type Ia supernovae (SNe Ia) are useful distance indicators in cosmology, provided their luminosity is standardized by applying empirical corrections based on light-curve properties…
