Halo Substructure in the SDSS-Gaia Catalogue : Streams and Clumps
G. C. Myeong, N. W. Evans, V. Belokurov +2
We use the SDSS-Gaia Catalogue to identify six new pieces of halo substructure. SDSS-Gaia is an astrometric catalogue that exploits SDSS data release 9 to provide first epoch photo…
Galaxies with Shells in the Illustris Simulation: Metallicity Signatures
Ana-Roxana Pop, Annalisa Pillepich, Nicola C. Amorisco +1
Stellar shells are low surface brightness arcs of overdense stellar regions, extending to large galactocentric distances. In a companion study, we identified 39 shell galaxies in a…
Formation and Incidence of Shell Galaxies in the Illustris Simulation
Ana-Roxana Pop, Annalisa Pillepich, Nicola C. Amorisco +1
Shells are low surface brightness tidal debris that appear as interleaved caustics with large opening angles, often situated on both sides of the galaxy center. In this paper, we s…
Deadly dark matter cusps vs faint and extended star clusters: Eridanus II and Andromeda XXV
Nicola C. Amorisco
The recent detection of two faint and extended star clusters in the central regions of two Local Group dwarf galaxies, Eridanus II and Andromeda XXV, raises the question of whether…
The accreted stellar halo as a window on halo assembly in L* galaxies
Nicola C. Amorisco
Theory and observations agree that the accreted stellar halos (ASHs) of Milky Way-like galaxies display significant scatter. I take advantage of this stochasticity to invert the li…
