A Substellar Companion to the Dusty Pleiades Star HD 23514

David R. Rodriguez, Christian Marois, B. Zuckerman +2

With adaptive optics imaging at Keck observatory, we have discovered a substellar companion to the F6 Pleiades star HD 23514, one of the dustiest main-sequence stars known to date…

Baryon Content of Massive Galaxy Clusters at z=0-0.6

Yen-Ting Lin, S. Adam Stanford, Peter R. M. Eisenhardt +3

We study the relationship between two major baryonic components in galaxy clusters, namely the stars in galaxies, and the ionized gas in the intracluster medium (ICM), using 94 clu…

A Surprising Dynamical Mass for V773~Tau~B

A. Boden, G. Torres, G. Duchene +4

We report on new high-resolution imaging and spectroscopy on the multiple T Tauri star system V773 Tau over the 2003 -- 2009 period. With these data we derive relative astrometry,…

Indication for the disappearance of reactor electron antineutrinos in the Double Chooz experiment

Y. Abe, C. Aberle, T. Akiri +182

The Double Chooz Experiment presents an indication of reactor electron antineutrino disappearance consistent with neutrino oscillations. A ratio of 0.944 0.016 (stat) 0…

B0 meson decays to rho0 K*0, f0 K*0, and rho-K*+, including higher K* resonances

The BABAR Collaboration

We present branching fraction measurements for the decays B0 -> rho0 K*0, B0 -> f0 K*0, and B0 -> rho- K*+, where K* is an S-wave (K pi)_0* or a K*(892) meson; we also measure B0 -…

Light vector meson production in pp collisions at = 7 TeV

ALICE Collaboration

The ALICE experiment has measured low-mass dimuon production in pp collisions at TeV in the dimuon rapidity region 2.5<y<4. The observed dimuon mass spectrum is desc…
