THE METAL-POOR KNEE IN THE FORNAX DWARF SPHEROIDAL GALAXY [PDF]

open access: yes, 2014
We present α-element abundances of Mg, Si, and Ti for a large sample of field stars in two outer fields of the Fornax dwarf spheroidal (dSph) galaxy, obtained with Very Large Telescope/GIRAFFE (R ∼ 16, 000).

The Effect of Tidal Stripping on Composite Stellar Populations in Dwarf Spheroidal Galaxies [PDF]

open access: yes, 2009
We use N-body simulations to study the effects of tides on the kinematical structure of satellite galaxies orbiting a Milky Way-like potential. Our work is motivated by observations of dwarf spheroidal galaxies in the Local Group, for which often a ...

A CHEMICAL CONFIRMATION OF THE FAINT BOÖTES II DWARF SPHEROIDAL GALAXY [PDF]

open access: yes, 2014
We present a chemical abundance study of the brightest confirmed member star of the ultra-faint dwarf galaxy Boötes II from Keck/HIRES high-resolution spectroscopy at moderate signal-to-noise ratios.

A Dynamically Distinct Stellar Population in the Leading Arm of the Sagittarius Stream

open access: yesThe Astrophysical Journal Letters, 2023
We present a chemical and dynamical analysis of the leading arm (LA) and trailing arm (TA) of the Sagittarius (Sgr) stream, as well as for the Sgr dwarf galaxy core (SC), using red giant branch, main-sequence, and RR Lyrae stars from large spectroscopic ...

Origin of structural and kinematical properties of the Small Magellanic Cloud

open access: yes, 2009
We investigate structural, kinematical, and chemical properties of stars and gas in the Small Magellanic Cloud (SMC) interacting with the Large Magellanic Cloud (LMC) and the Galaxy based on a series of self-consistent chemodynamical simulations.

Young Globular Clusters and Dwarf Spheroidals [PDF]

open access: yes, 1999
Most of the globular clusters in the main body of the Galactic halo were formed almost simultaneously. However, globular cluster formation in dwarf spheroidal galaxies appears to have extended over a significant fraction of a Hubble time.

Schwarzschild models of the Sculptor dSph galaxy

open access: yesEPJ Web of Conferences, 2012
We have developed a spherically symmetric dynamical model of a dwarf spheroidal galaxy using the Schwarzschild method. This type of modelling yields constraints both on the total mass distribution (e.g.
