Multi-Element Abundance Measurements from Medium-Resolution Spectra. IV. Alpha Element Distributions in Milky Way Dwarf Satellite Galaxies
Evan N. Kirby, Judith G. Cohen, Graeme H. Smith +3
We derive the star formation histories of eight dwarf spheroidal (dSph) Milky Way satellite galaxies from their alpha element abundance patterns. Nearly 3000 stars from our previou…
Multi-Element Abundance Measurements from Medium-Resolution Spectra. II. Catalog of Stars in Milky Way Dwarf Satellite Galaxies
Evan N. Kirby, Puragra Guhathakurta, Joshua D. Simon +7
We present a catalog of Fe, Mg, Si, Ca, and Ti abundances for 2961 red giant stars that are likely members of eight dwarf satellite galaxies of the Milky Way (MW): Sculptor, Fornax…
Large violation of Bell inequalities using both particle and wave measurements
Daniel Cavalcanti, Nicolas Brunner, Paul Skrzypczyk +2
When separated measurements on entangled quantum systems are performed, the theory predicts correlations that cannot be explained by any classical mechanism: communication is exclu…
The ACS Fornax Cluster Survey. IV. Deprojection of the Surface Brightness Profiles of Early-Type Galaxies in the Virgo and Fornax Clusters: Investigating the "Core/Power-Law Dichotomy"
Lisa Glass, Laura Ferrarese, Patrick Cote +8
Although early observations with the Hubble Space Telescope (HST) pointed to a sharp dichotomy among early-type galaxies in terms of the logarithmic slope gamma' of their central s…
Rapid and robust spin state amplification
Tom Close, Femi Fadugba, Simon C. Benjamin +2
Electron and nuclear spins have been employed in many of the early demonstrations of quantum technology (QT). However applications in real world QT are limited by the difficulty of…
The Occurrence and Mass Distribution of Close-in Super-Earths, Neptunes, and Jupiters
Andrew W. Howard, Geoffrey W. Marcy, John Asher Johnson +7
The questions of how planets form and how common Earth-like planets are can be addressed by measuring the distribution of exoplanet masses and orbital periods. We report the occurr…
