Gaia and the Galactic Center Origin of Hypervelocity Stars
Warren R. Brown, Mario G. Lattanzi, Scott J. Kenyon +1
We use new Gaia measurements to explore the origin of the highest velocity stars in the Hypervelocity Star Survey. The measurements reveal a clear pattern in the B-type stars. Halo…
Not only once: the amazing gamma-ray activity of the blazar PKS 1510-089
F. D'Ammando, C. M. Raiteri, M. Villata +6
PKS 1510-089 is a powerful Flat Spectrum Radio Quasar at z=0.361 with radiative output dominated by the gamma-ray emission. In the last two years PKS 1510-089 showed high variabili…
TeV variability in blazars: how fast can it be?
G. Ghisellini, F. Tavecchio, G. Bodo +1
Recent Cerenkov observations of the two BL Lac objects PKS 2155-304 and Mkn 501 revealed TeV flux variability by a factor ~2 in just 3-5 minutes. Even accounting for the effects of…
A Massive Planet to the Young Disc Star HD 81040
A. Sozzetti, S. Udry, S. Zucker +9
We report the discovery of a massive planetary companion orbiting the young disc star HD 81040. Based on five years of precise radial-velocity measurements with the HIRES and ELODI…
