Origin of the Metallicity Distribution in the Thick Disc
Maider S. Miranda, Kate Pilkington, Brad K. Gibson +9
Aims. Using a suite of cosmological chemodynamical disc galaxy simulations, we assess how (a) radial metallicity gradients evolve with scaleheight; (b) the vertical metallicity gra…
The imprint of satellite accretion on the chemical and dynamical properties of disc galaxies
T. Ruiz-Lara, C. G. Few, B. K. Gibson +4
Aims: We study the effects of the cosmological assembly history on the chemical and dynamical properties of the discs of spiral galaxies as a function of radius. Methods: We make u…
Extragalactic archeology with the GHOSTS Survey I. - Age-resolved disk structure of nearby low-mass galaxies
David Streich, Roelof S. de Jong, Jeremy Bailin +5
We study the individual evolution histories of three nearby low-mass edge-on galaxies (IC 5052, NGC4244, and NGC5023). Using resolved stellar populations, we constructed star count…
The Parent Populations of 6 groups identified from Chemical Tagging in the Solar neighborhood
Alice C. Quillen, Borja Anguiano, Gayandhi De Silva +4
We estimate the size and distribution of the parent populations for the 6 largest (at least 20 stars in the Solar neighborhood) chemical groups identified in the Chemical Tagging e…
Chemical Cartography with APOGEE: Metallicity Distribution Functions and the Chemical Structure of the Milky Way Disk
Michael R. Hayden, Jo Bovy, Jon A. Holtzman +32
Using a sample of 69,919 red giants from the SDSS-III/APOGEE Data Release 12, we measure the distribution of stars in the [/Fe] vs. [Fe/H] plane and the metallicity distribution…
On the Formation of Galactic Thick Disks
I. Minchev, M. Martig, D. Streich +3
Recent spectroscopic observations in the Milky Way suggest that the chemically defined thick disk (stars with high [alpha/Fe] ratios and thus old) has a significantly smaller scale…
The stellar kinematics of co-rotating spiral arms in Gaia mock observations
Jason A. S. Hunt, Daisuke Kawata, Robert J. J. Grand +3
We have observed an N-body/Smoothed Particle Hydrodynamics simulation of a Milky Way like barred spiral galaxy. We present a simple method that samples N-body model particles into…
