The impact of hot mode accretion and angular momentum conservation on metallicity gradients of galactic discs
Jennifer K. S. Friske, Filippo Fraternali, Gabriele Pezzulli
The hot circumgalactic medium (CGM) of a galaxy inevitably rotates more slowly than the cold gas in the disc it surrounds, due to a higher pressure support against gravity. If it a…
The JWST Galactic Center Survey -- A White Paper
Rainer Schoedel, Steve Longmore, Jonny Henshaw +111
The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…
Chemical Evolution in Nuclear Stellar Discs
Jennifer K S Friske, Ralph Schönrich
Nuclear Stellar Discs (NSDs) have been observed in the vast majority of barred disc galaxies including the Milky Way. Their intense star formation is sustained by the intense gas i…
On the likelihoods of finding very metal-poor (and old) stars in the Milky Way's disc, bulge, and halo
Diego Sotillo-Ramos, Maria Bergemann, Jennifer K. S. Friske +1
Recent observational studies have uncovered a small number of very metal-poor stars with cold kinematics in the Galactic disc and bulge. However, their origins remain enigmatic. We…
The Prince and the Pauper: Evidence for the early high-redshift formation of the Galactic -poor disc population
Matthew Raymond Gent, Philipp Eitner, Aldo Serenelli +5
Context. The presence of [/Fe]-[Fe/H] bi-modality in the Milky Way disc has animated the Galactic archaeology community since more than two decades. Aims. Our goal is to investi…
Galactic Bar Resonances Inferred from Kinematically Hot Stars in Gaia EDR3
Daisuke Kawata, Junichi Baba, Jason A. S. Hunt +5
Using a numerical simulation of an isolated barred disc galaxy, we first demonstrate that the resonances of the inner bar structure induce more prominent features in the action spa…
Resonance sweeping by a decelerating Galactic bar
Rimpei Chiba, Jennifer K. S. Friske, Ralph Schönrich
We provide the first quantitative evidence for the deceleration of the Galactic bar from local stellar kinematics in agreement with dynamical friction by a typical dark matter halo…
More than just a wrinkle: A wave-like pattern in radial velocity vs. angular momentum from Gaia Data
Jennifer Friske, Ralph Schönrich
We present a newly found wave--like pattern in mean Galactocentric radial velocity U_g vs. guiding centre radius R_g or angular momentum L_z of stars in the RV subsample of Gaia DR…
