A measurement of the Galactic plane mass density from binary pulsar accelerations
Sukanya Chakrabarti, Philip Chang, Michael T. Lam +2
We use compiled high-precision pulsar timing measurements to directly measure the Galactic acceleration of binary pulsars relative to the Solar System barycenter. Given the vertica…
Towards a direct measure of the Galactic acceleration
Sukanya Chakrabarti, Jason Wright, Philip Chang +9
High precision spectrographs can enable not only the discovery of exoplanets, but can also provide a fundamental measurement in Galactic dynamics. Over about ten year baselines, th…
Birth Sites of Young Stellar Associations and Recent Star Formation in a Flocculent Corrugated Disk
Alice C. Quillen, Alex R. Pettitt, Sukanya Chakrabarti +3
With backwards orbit integration we estimate birth locations of young stellar associations and moving groups identified in the solar neighborhood that are younger than 70 Myr. The…
Dynamically Produced Moving Groups in Interacting Simulations
Peter Craig, Sukanya Chakrabarti, Heidi Jo Newberg +1
We show that Smoothed Particle Hydrodynamics (SPH) simulations of dwarf galaxies interacting with a Milky Way-like disk produce moving groups in the simulated stellar disk. We anal…
The GALAH survey and Gaia DR2: dissecting the stellar disc's phase space by age, action, chemistry and location
Joss Bland-Hawthorn, Sanjib Sharma, Thor Tepper-Garcia +24
We use the second data releases of the ESA Gaia astrometric survey and the high-resolution GALAH spectroscopic survey to analyse the structure of our Galaxy's disc components. With…
Spiral arm crossings inferred from ridges in Gaia stellar velocity distributions
Alice C. Quillen, Ismael Carrillo, Friedrich Anders +7
The solar neighborhood contains disc stars that have recently crossed spiral arms in the Galaxy. We propose that boundaries in local velocity distributions separate stars that have…
