On the radial velocity wave in the Galactic disk
Chris Hamilton, Andrew Mummery, Joss Bland-Hawthorn
Stars in the Galactic disk have mean radial velocities that oscillate as a function of angular momentum . This `- wave' signal also exh…
Galactokinetics II: Spiral structure
Chris Hamilton, Shaunak Modak, Scott Tremaine
We present a unified theory of linear spiral structure in stellar disks. We begin by identifying the characteristic scales involved in the spiral structure problem and listing some…
Characterizing Density and Gravitational Potential Fluctuations of the Interstellar Medium
Shaunak Modak, Eve C. Ostriker, Chris Hamilton +1
Substructure in the interstellar medium (ISM) is crucial for establishing the correlation between star formation and feedback and has the capacity to significantly perturb stellar…
Galactic echoes
Rimpei Chiba, Jupiter Ding, Chris Hamilton +2
Gaia has revealed a variety of substructures in the phase space of stars in the Solar neighborhood, including the vertical `Snail' in space. Such substructures are often…
Origin of the two-armed vertical phase-spiral in the inner Galactic disk
Rimpei Chiba, Neige Frankel, Chris Hamilton
Gaia recently revealed a two-armed spiral pattern in the vertical phase-space distribution of the inner Galactic disk (guiding radius kpc), indicating that…
On the maximum disk heating attributable to fuzzy dark matter
Chris Hamilton
Fuzzy dark matter (FDM) granulations would drive orbital transport of stars in galactic disks, and in particular would produce roughly equal amounts of radial heating and radial mi…
