Turbulent gas-rich discs at high redshift: the origin of early massive stellar bars
Joss Bland-Hawthorn, Thor Tepper-Garcia, Chris Hamilton +4
Recent observations combining the power of ALMA and JWST have revealed large ( kpc), massive () stellar bars at when the Universe…
Swing amplification in star-gas disks
Abhishek Hegade K. R., Chris Hamilton
Recent JWST and ALMA observations have revealed stellar bars and spirals in gas-rich galactic disks at redshifts as high as . The simplest theoretical paradigm we have…
Short-Range Forces Can Catalyze Extreme Orbital Evolution in Hierarchical Triples
Ygal Y. Klein, Chris Hamilton
Hierarchical triples are promising environments for producing exotica such as black hole mergers and hot Jupiters, because of the von Zeipel-Lidov-Kozai (ZLK) effect, whereby a dis…
Interstellar Medium-Driven Orbital Transport -- I. Radial Heating and Migration
Shaunak Modak, Chris Hamilton, Eve C. Ostriker +1
Interstellar medium (ISM) structures gravitationally perturb stellar orbits in galactic disks, driving orbital heating and migration. However, studies of these transport processes…
Phase spirals across galactic disks I: Exploring dynamical influences on winding
Kiyan Tavangar, Kathryn V. Johnston, Jason A. S. Hunt +4
The vertical phase-space spirals in the Milky Way are clear evidence of disequilibrium. However, they are challenging to study because phase mixing signals evolve under the influen…
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…
Why is the Galactic disk so cool?
Chris Hamilton, Shaunak Modak, Scott Tremaine
The bulk of old stars in the Galactic disk have migrated radially by up to several kpc in their lifetimes, yet the disk has remained relatively cool, i.e., the ratio of radial heat…
