    DAHe white dwarfs from the DESI Survey
    A new class of white dwarfs, dubbed DAHe, that present Zeeman-split Balmer lines in emission has recently emerged. However, the physical origin of these...

    Dark Energy Survey Deep Field photometric redshift performance and training incompleteness assessment
    Context. The determination of accurate photometric redshifts (photo-zs) in large imaging galaxy surveys is key for cosmological studies. One of the most common...
