Ultra-High Energy Cosmic Rays from Quasar Remnants
C. Isola, G. Sigl, G. Bertone
One of the models recently proposed to explain the origin of the ultra high energy cosmic rays assumes that these particles may be accelerated by the electromotive force around pre…
A Quest for PMS candidate stars at low metallicity: Variable HAe/Be and Be stars in the Small Magellanic Cloud
W. J. de Wit, J-P. Beaulieu, H. J. G. L. M. Lamers +3
We report the discovery of 5 new Herbig Ae/Be candidate stars in the Small Magellanic Cloud in addition to the 2 reported in Beaulieu et al. (2001). We discuss these 7 HAeBe candid…
String Imprints from a Pre-inflationary Era
P. P. Avelino, C. J. A. P. Martins
We derive the equations governing the dynamics of cosmic strings in a flat anisotropic universe of Bianchi type I and study the evolution of simple cosmic string loop solutions. We…
Halo model prediction of the cosmic magnification statistics: the full non-linear contribution
Masahiro Takada, Takashi Hamana
The lensing magnification effect due to large-scale structure is statistically measurable by correlation of size fluctuations in distant galaxy images as well as by the QSO-galaxy…
The VLT-UVES survey for molecular hydrogen in high-redshift damped Lyman-alpha systems
C. Ledoux, P. Petitjean, R. Srianand
We have searched for molecular hydrogen in damped Lyman-alpha (DLA) and sub-DLA systems at z>1.8 using UVES at the VLT. Out of the 33 systems in our sample, 8 have firm and 2 have…
