An X-ray and Multiwavelength Survey of Highly Radio-Loud Quasars at z > 4: Jet-Linked Emission in the Brightest Radio Beacons of the Early Universe
Jianfeng Wu, W. N. Brandt, Brendan P. Miller +3
(Abridged) We present a systematic study of the X-ray and multiwavelength properties of a sample of 17 highly radio-loud quasars (HRLQs) at z > 4 with sensitive X-ray coverage from…
Does the Sagittarius Stream constrain the Milky Way halo to be triaxial?
Rodrigo Ibata, Geraint F. Lewis, Nicolas F. Martin +2
Recent analyses of the stellar stream of the Sagittarius dwarf galaxy have claimed that the kinematics and three-dimensional location of the M-giant stars in this structure constra…
CLASH: The enhanced lensing efficiency of the highly elongated merging cluster MACS J0416.1-2403
A. Zitrin, M. Meneghetti, K. Umetsu +21
We perform a strong-lensing analysis of the merging galaxy cluster MACS J0416.1-2403 (M0416; z=0.42) in recent CLASH/HST observations. We identify 70 new multiple images and candid…
A lower radius and mass for the transiting extrasolar planet HAT-P-8b
L. Mancini, J. Southworth, S. Ciceri +10
Context. The extrasolar planet HAT-P-8 b was thought to be one of the more inflated transiting hot Jupiters. Aims. By using new and existing photometric data, we computed precise e…
Dynamical Evolution and Spatial Mixing of Multiple Population Globular Clusters
Enrico Vesperini, Stephen L. W. McMillan, Francesca D'Antona +1
In this paper we study the long-term dynamical evolution of multiple-population clusters, focusing on the evolution of the spatial distributions of the first- (FG) and second-gener…
An aluminium tool for multiple stellar generations in the globular clusters 47 Tuc and M 4
Eugenio Carretta, Raffaele Gratton, Angela Bragaglia +2
We present aluminium abundances for a sample of about 100 red giant stars in each of the Galactic globular clusters 47 Tuc (NGC 104) and M 4 (NGC 6121). We have derived homogeneous…
