Two-point correlation function studies for the Milky Way: discovery of spatial clustering from disk excitations and substructure
Austin Hinkel, Susan Gardner, Brian Yanny
We introduce a two-particle correlation function (2PCF) for the Milky Way, constructed to probe spatial correlations in the orthogonal directions of the stellar disk in the Galacti…
The Milky Way, Coming into Focus: Precision Astrometry Probes its Evolution, and its Dark Matter
Susan Gardner, Samuel D. McDermott, Brian Yanny
The growing trove of precision astrometric observations from the Gaia space telescope and other surveys is revealing the structure and dynamics of the Milky Way in ever more exquis…
Axial Asymmetry Studies in Gaia Data Release 2 Yield the Pattern Speed of the Galactic Bar
Austin Hinkel, Susan Gardner, Brian Yanny
Our recent studies of axial-symmetry breaking in the nearby () star counts are sensitive to the distortions of stellar orbits perpendicular and parallel to the or…
Probing Axial Symmetry Breaking in the Galaxy with Gaia Data Release 2
Austin Hinkel, Susan Gardner, Brian Yanny
We study a set of solar neighborhood ( kpc) stars from Gaia Data Release 2 to determine azimuthal star count differences, i.e., left and right of the line from the Galactic…
Applying Noether's theorem to matter in the Milky Way: evidence for external perturbations and non-steady-state effects from Gaia Data Release 2
Susan Gardner, Austin Hinkel, Brian Yanny
We apply Noether's theorem to observations of main-sequence stars from the Gaia Data Release 2 archive to probe the matter distribution function of the Galaxy. That is, we examine…
Milky Way Tomography with K and M Dwarf Stars: the Vertical Structure of the Galactic Disk
Deborah Ferguson, Susan Gardner, Brian Yanny
We use the number density distributions of K and M dwarf stars with vertical height from the Galactic disk, determined using observations from the Sloan Digital Sky Survey, to prob…
The Stellar Number Density Distribution in the Local Solar Neighborhood is North-South Asymmetric
Brian Yanny, Susan Gardner
We study the number density distribution of a sample of K and M dwarf stars, matched North and South of the Galactic plane within a distance of 2 kpc from the sun, using observatio…
Galactoseismology: Discovery of Vertical Waves in the Galactic Disk
Lawrence M. Widrow, Susan Gardner, Brian Yanny +2
We present evidence for a Galactic North-South asymmetry in the number density and bulk velocity of solar neighborhood stars. The number density profile, which is derived from main…
