Searching for Ultra-light Dark Matter in Spatial Correlations of White Dwarf Structure
Nicole R. Crumpler, Nadia L. Zakamska, Gautham Adamane Pallathadka +1
If dark matter is ultra-light and has certain Standard Model interactions, it can change the mass-radius relation of white dwarf stars. The coherence length of ultra-light dark mat…
Double White Dwarf Binaries in SDSS-V DR19 : A catalog of DA white dwarf binaries and constraints on the binary population
Gautham Adamane Pallathadka, Vedant Chandra, Nadia L. Zakamska +17
The fifth-generation Sloan Digital Sky Survey (SDSS-V) includes the first large-scale spectroscopic survey of white dwarfs (WDs) in the era of Gaia parallaxes. SDSS-V collects mult…
Resolution-Corrected White Dwarf Gravitational Redshifts Validate SDSS-V Wavelength Calibration and Enable Accurate Mass-Radius Tests
Stefan M. Arseneau, J. J. Hermes, Nadia L. Zakamska +7
Leveraging the large sample size of low-resolution spectroscopic surveys to constrain white dwarf stellar structure requires an accurate understanding of the shapes of hydrogen abs…
A Large Catalog of DA White Dwarf Characteristics Using SDSS and Gaia Observations
Nicole R. Crumpler, Vedant Chandra, Nadia L. Zakamska +12
We present a catalog of 8545 and 19,257 unique DA white dwarfs observed in SDSS Data Release 19 and previous SDSS data releases, respectively. This is the largest catalog of both s…
Double White Dwarf Binaries in SDSS-V DR19 : The discovery of a rare DA+DQ white dwarf binary with 31 hour orbital period
Gautham Adamane Pallathadka, Vedant Chandra, Boris T. Gansicke +13
Binaries of two white dwarfs (WDs) are an important class of astrophysical objects that are theorized to lead to Type Ia supernovae and are also used to gain insight into complex p…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
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…
Detection of the Temperature Dependence of the White Dwarf Mass-Radius Relation with Gravitational Redshifts
Nicole R. Crumpler, Vedant Chandra, Nadia L. Zakamska +8
Models predict that the well-studied mass-radius relation of white dwarf stars depends on the temperature of the star, with hotter white dwarfs having larger masses at a given radi…
Measuring The Mass-Radius Relation of White Dwarfs Using Wide Binaries
Stefan Arseneau, Vedant Chandra, Hsiang-Chih Hwang +10
Measuring the mass-radius relation of individual white dwarfs is an empirically challenging task that has been performed for only a few dozen stars. We measure the white dwarf mass…
Discovery of a Proto-White Dwarf with a Massive Unseen Companion
Gautham Adamane Pallathadka, Vedant Chandra, Nadia L. Zakamska +8
We report the discovery of SDSS~J022932.28+713002.7, a nascent extremely low-mass (ELM) white dwarf (WD) orbiting a massive ( at 2 confidence) companion with a per…
Constraining Electromagnetic Signals from Black Holes with Hair
Nicole R. Crumpler
We constrain a broad class of "hairy" black hole models capable of directly sourcing electromagnetic radiation during a binary black hole merger. This signal is generic and model-i…
A Photometric Analysis of the Relationship Between Type Ia Supernova UV Flux and Host Galaxy Metallicity
Peter J. Brown, Nicole R. Crumpler
The effect of progenitor metallicity on Type Ia Supernovae (SNe Ia) has important cosmological implications due to the need for these standardizable candles to be compared across l…
