Elemental Abundances in M31: Properties of the Inner Stellar Halo
Ivanna Escala, Evan N. Kirby, Karoline M. Gilbert +3
We present measurements of [Fe/H] and [/Fe] for 128 individual red giant branch stars (RGB) in the stellar halo of M31, including its Giant Stellar Stream (GSS), obtained using…
Quantifying the Stellar Halo's Response to the LMC's Infall with Spherical Harmonics
Emily C. Cunningham, Nicolas Garavito-Camargo, Alis J. Deason +6
The vast majority of the mass in the Milky Way (MW) is in dark matter (DM); we therefore cannot directly observe the MW mass distribution, and have to use tracer populations in ord…
The power of co-ordinate transformations in dynamical interpretations of Galactic structure
Jason A. S. Hunt, Kathryn V. Johnston, Alex R. Pettitt +3
DR2 has provided an unprecedented wealth of information about the positions and motions of stars in our Galaxy, and has highlighted the degree of disequilibria in the disc.…
Elemental Abundances in M31: A Comparative Analysis of Iron and Alpha Element Abundances in the Outer Disk, Giant Stellar Stream, and Inner Halo of M31
Ivanna Escala, Karoline M. Gilbert, Evan N. Kirby +3
We measured [Fe/H] and [/Fe] using spectral synthesis of low-resolution stellar spectroscopy for 70 individual red giant branch stars across four fields spanning the outer disk,…
The Multidimensional Milky Way
Robyn E. Sanderson, Jeffrey L. Carlin, Emily C. Cunningham +6
Studying our Galaxy, the Milky Way (MW), gives us a close-up view of the interplay between cosmology, dark matter, and galaxy formation. In the next decade our understanding of the…
Elemental Abundances in M31: Alpha and Iron Element Abundances from Low-Resolution Resolved Stellar Spectroscopy in the Stellar Halo
Ivanna Escala, Evan N. Kirby, Karoline M. Gilbert +2
Measurements of [Fe/H] and [/Fe] can probe the minor merging history of a galaxy, providing a direct way to test the hierarchical assembly paradigm. While measurements of [/F…
