Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy

Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217

The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…

Cataclysmic variables from Sloan Digital Sky Survey -- V (2020-2023) identified using machine learning

Keith Inight, Boris T. Gänsicke, Axel Schwope +16

SDSS-V is carrying out a dedicated survey for white dwarfs, single and in binaries, and we report the analysis of the spectroscopy of 504 cataclysmic variables (CVs) and CV candida…

Single magnetic white dwarfs with Balmer emission lines: A small class with consistent physical characteristics as possible signposts for close-in planetary companions

Boris T. Gaensicke, Pablo Rodriguez-Gil, Nicola P. Gentile Fusillo +4

We report the identification of SDSS J121929.45+471522.8 as the third apparently isolated magnetic (B~18.5+/-1.0,MG) white dwarf exhibiting Zeeman-split Balmer emission lines. The…

V498 Hya, a new candidate for a period bouncer Cataclysmic Variable

Gagik Tovmassian, Keith Inight, Anna Francesca Pala +5

V498 Hya (SDSS J084555.07+033929.2) was identified as a short-period cataclysmic variable (CV) by the Catalina Real-Time Transient Survey (CRTS) in 2008. The superhump period was m…

The DESI Early Data Release White Dwarf Catalogue

Christopher J. Manser, Paula Izquierdo, Boris T. Gänsicke +51

The Early Data Release (EDR) of the Dark Energy Spectroscopic Instrument (DESI) comprises spectroscopy obtained from 2020 December 14 to 2021 June 10. White dwarfs were targeted by…

DAHe white dwarfs from the DESI survey

Christopher J. Manser, Boris T. Gänsicke, Keith Inight +16

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 emission lines remains uncl…

Long-term variability in debris transiting white dwarfs

Amornrat Aungwerojwit, Boris T. Gaensicke, Vikram S. Dhillon +7

Combining archival photometric observations from multiple large-area surveys spanning the past 17 years, we detect long-term variability in the light curves of ZTFJ032833.52-121945…

A catalogue of cataclysmic variables from 20 years of the Sloan Digital Sky Survey with new classifications, periods, trends and oddities

Keith Inight, Boris Gänsicke, Elmé Breedt +7

We present a catalogue of 507 cataclysmic variables (CVs) observed in SDSS I to IV including 70 new classifications collated from multiple archival data sets. This represents the l…
