Description
The first data release from the Dark Energy Spectroscopic Instrument has yielded the largest sample of spectroscopically-confirmed white dwarfs, observed in an almost-unbiased, magnitude-limited survey. Our catalogue contains over 40000 white dwarfs, around two-thirds of which are newly-identified, all with spectral classifications and stellar parameters from model-fitting. Highlights include many new planetary systems and interacting binaries, plus some rare and exotic objects. I will give a brief tour through the catalogue, and reflect on whether human spectral classification still has a place in the machine-learning era.
