Constraining cosmology with the Gaia-unWISE Quasar Catalog and CMB lensing: structure growth
David Alonso, Giulio Fabbian, Kate Storey-Fisher +4
We study the angular clustering of Quaia, a Gaia- and unWISE-based catalog of over a million quasars with an exceptionally well-defined selection function. With it, we derive cosmo…
KPM: A Flexible and Data-Driven K-Process Model for Nucleosynthesis
Emily J. Griffith, David W. Hogg, Julianne J. Dalcanton +4
The element abundance pattern found in Milky Way disk stars is close to two-dimensional, dominated by production from one prompt process and one delayed process. This simplicity is…
Quaia, the Gaia-unWISE Quasar Catalog: An All-Sky Spectroscopic Quasar Sample
Kate Storey-Fisher, David W. Hogg, Hans-Walter Rix +4
We present a new, all-sky quasar catalog, Quaia, that samples the largest comoving volume of any existing spectroscopic quasar sample. The catalog draws on the 6,649,162 quasar can…
Equivariant geometric convolutions for emulation of dynamical systems
Wilson G. Gregory, David W. Hogg, Ben Blum-Smith +3
Machine learning methods are increasingly being employed as surrogate models in place of computationally expensive and slow numerical integrators for a bevy of applications in the…
The Panchromatic Hubble Andromeda Treasury XX: The Disk of M31 is Thick
Julianne J. Dalcanton, Eric F. Bell, Yumi Choi +6
We present a new approach to measuring the thickness of a partially face-on stellar disk, using dust geometry. In a moderately-inclined disk galaxy, the fraction of reddened stars…
Towards fully covariant machine learning
Soledad Villar, David W. Hogg, Weichi Yao +2
Any representation of data involves arbitrary investigator choices. Because those choices are external to the data-generating process, each choice leads to an exact symmetry, corre…
