Chemical Abundance Analysis of the Extremely Metal-Poor Star HE 1300+0157

Anna Frebel, John E. Norris, Wako Aoki +5

We present a detailed chemical abundance analysis of HE 1300+0157, a subgiant with [Fe/H]=-3.9. From a high-resolution, high-S/N Subaru/HDS spectrum we find the star to be enriched…

A Survey for Supernovae in Massive High-Redshift Clusters

Keren Sharon, A. Gal-Yam, D. Maoz +12

We describe our ongoing program designed to measure the SN-Ia rate in a sample of massive z=0.5-0.9 galaxy clusters. The SN-Ia rate is a poorly known observable, especially at high…

Near-Infrared Spectroscopy of Carbon-Enhanced Metal-Poor Stars. I. A SOAR/OSIRIS Pilot Study

Timothy C. Beers, Thirupathi Sivarani, Brian Marstellar +3

We report on an abundance analysis for a pilot study of seven Carbon-Enhanced Metal-Poor (CEMP) stars, based on medium-resolution optical and near-infrared spectroscopy. The optica…

Excitation of solar-like oscillations across the HR diagram

R. Samadi, D. Georgobiani, R. Trampedach R. +3

We extend semi-analytical computations of excitation rates for solar oscillation modes to those of other solar-like oscillating stars to compare them with recent observations. Nume…

Velocities measured in small scale solar magnetic elements

Øystein Langangen, Mats Carlsson, Luc Rouppe van der Voort +1

We have obtained high resolution spectrograms of small scale magnetic structures with the Swedish 1-m Solar Telescope. We present Doppler measurements at $0\farcs{2}$ spatial resol…

Discovery of TeV Gamma-Ray Emission from the Cygnus Region of the Galaxy

A. A. Abdo, B. Allen, D. Berley +36

The diffuse gamma radiation arising from the interaction of cosmic ray particles with matter and radiation in the Galaxy is one of the few probes available to study the origin of t…
