    Lee, J.; Acevedo, M.; Sako, M.; Vincenzi, M.; Brout, D.; Sanchez, B.; Chen, R.; Davis, Tamara M.; Jarvis, M.; Scolnic, D.; Qu, H.; Galbany, L.; Kessler, R.; Lasker, J.; Sullivan, M.; Wiseman, P.; Aguena, M.; Allam, S.; Alves, O.; Andrade-Oliveira, F.; Bertin, E.; Bocquet, S.; Brooks, D.; Burke, D. L.; Carnero Rosell, A.; Carrasco Kind, M.; Carretero, J.; Costanzi, M.; da Costa, Luiz N.; Pereira, M.E.S.; De Vicente, J.; Desai, S.; Diehl, H. T.; Doel, P.; Everett, S.; Ferrero, Ismael (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Wavelength-dependent atmospheric effects impact photometric supernova flux measurements for ground-based observations. We present corrections on supernova flux measurements from the Dark Energy Survey Supernova Program's ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Abstract Redshift measurements, primarily obtained from host galaxies, are essential for inferring cosmological parameters from type Ia supernovae (SNe Ia). Matching SNe to host galaxies using images is nontrivial, ...
