Pressure-Induced Structure Transitions in Eu Metal to 92 GPa
W. Bi, Y. Meng, R. S. Kumar +6
Synchrotron x-ray diffraction experiments have been carried out on Eu metal at ambient temperature to pressures as high as 92 GPa (0.92 Mbar). Following the well-known bcc-to-hcp t…
Transit Timing Variation Analysis of OGLE-TR-132b with Seven New Transits
Elisabeth R. Adams, Mercedes Lopez-Morales, James L. Elliot +2
We report the results of the first transit timing variation (TTV) analysis of the very hot Jupiter OGLE-TR-132b, using ten transits collected over a seven-year period. Our analysis…
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…
The evolution of early-type galaxies in clusters from z~ 0.8 to z~ 0: the ellipticity distribution and the morphological mix
Benedetta Vulcani, Bianca M. Poggianti, Alan Dressler +10
We present the ellipticity distribution and its evolution for early-type galaxies in clusters from z~0.8 to z~0, based on the WIde-field Nearby Galaxy-cluster Survey (WINGS)(0.04<z…
MOIRCS Deep Survey. IX. Deep Near-Infrared Imaging Data and Source Catalog
Masaru Kajisawa, Takashi Ichikawa, Ichi Tanaka +13
We present deep J-, H-, and Ks-band imaging data of the MOIRCS Deep Survey (MODS), which was carried out with Multi-Object Infrared Camera and Spectrograph (MOIRCS) mounted on the…
The Dawn of the Red: Star formation histories of group galaxies over the past 5 billion years
Sean L. McGee, Michael L. Balogh, David J. Wilman +4
We examine the star formation properties of group and field galaxies in two surveys, the Sloan Digital Sky Survey (SDSS; at z ~ 0.08) and the Group Environment and Evolution Collab…
