Passing through the bounce in the ekpyrotic models
Jerome Martin, Patrick Peter, Nelson Pinto Neto +1
By considering a simplified but exact model for realizing the ekpyrotic scenario, we clarify various assumptions that have been used in the literature. In particular, we discuss th…
Ultra-High Energy Cosmic Rays from Neutrino Emitting Acceleration Sources?
Oleg E. Kalashev, Vadim A. Kuzmin, Dmitry V. Semikoz +1
We demonstrate by numerical flux calculations that neutrino beams producing the observed highest energy cosmic rays by weak interactions with the relic neutrino background require…
Large-Scale Structure of the Universe and Cosmological Perturbation Theory
F. Bernardeau, S. Colombi, E. Gaztanaga +1
We review the formalism and applications of non-linear perturbation theory (PT) to understanding the large-scale structure of the Universe. We first discuss the dynamics of gravita…
Abundances of Deuterium, Oxygen, and Nitrogen in the Local Interstellar Medium: Overview of First Results from the Far Ultraviolet Spectroscopic Explorer Mission
H. W. Moos, K. R. Sembach, A. Vidal-Madjar +33
Observations obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) have been used to determine the column densities of D I, O I, and N I along seven sight lines that prob…
The Large Zenith Telescope Survey: a deep survey using a 6-m liquid mirror telescope
Remi A. Cabanac, Paul Hickson, Valerie de Lapparent
The Large Zenith Telescope Survey whose construction is almost completed (first light expected in spring 2002) near Vancouver (Canada) is designed to observed a total strip of ~17'…
The different Clustering of red and blue galaxies: a robust signal from w(theta)
Remi A. Cabanac, Valerie de Lapparent, P. Hickson
A sample of ~20,000 galaxies covering 0.76 deg2 were observed with the CFHT-UH8K up to V<23.5 and I<22.5. The angular correlation analysis of the red selected sample (V-I>1.4) show…
Deuterium Toward WD1634-573: Results from the Far Ultraviolet Spectroscopic Explorer (FUSE) Mission
B. E. Wood, J. L. Linsky, G. Hebrard +5
We use Far Ultraviolet Spectrocopic Explorer (FUSE) observations to study interstellar absorption along the line of sight to the white dwarf WD1634-573 (d=37.1+/-2.6 pc). Combining…
Dimming of Supernovae by Photon-Pseudoscalar Conversion and the Intergalactic Plasma
Cédric Deffayet, Diego Harari, Jean-Philippe Uzan +1
Recently Csaki, Kaloper and Terning (hep-ph/0111311) suggested that the observed dimming of distant type Ia supernovae may be a consequence of mixing of the photons with very light…
Associated absorption in radio quasars. I. C IV absorption and the growth of radio sources
J. C. Baker, R. W. Hunstead, R. M. Athreya +4
We assess the global properties of associated C IV 1548,1550 absorption lines measured in the spectra of radio-loud quasars drawn from a near-complete, low-frequency selected sampl…
Post-Newtonian approximation for isolated systems calculated by matched asymptotic expansions
Olivier Poujade, Luc Blanchet
Two long-standing problems with the post-Newtonian approximation for isolated slowly-moving systems in general relativity are: (i) the appearance at high post-Newtonian orders of d…
Innermost circular orbit of binary black holes at the third post-Newtonian approximation
Luc Blanchet
The equations of motion of two point masses have recently been derived at the 3PN approximation of general relativity. From that work we determine the location of the innermost cir…
B-modes in cosmic shear from source redshift clustering
P. Schneider, L. van Waerbeke, Y. Mellier
Weak gravitational lensing by the large scale structure can be used to probe the dark matter distribution in the Universe directly and thus to probe cosmological models. The recent…
Generalized observers and velocity measurements in General Relativity
P. Crawford, I. Tereno
To resolve some unphysical interpretations related to velocity measurements by static observers, we discuss the use of generalized observer sets, give a prescription for defining t…
Deuterium and Oxygen Toward Feige 110: Results from the Far Ultraviolet Spectroscopic Explorer (FUSE) Mission
S. D. Friedman, J. C. Howk, P. Chayer +11
We present measurements of the column densities of interstellar DI and OI made with the Far Ultraviolet Spectroscopic Explorer (FUSE), and of HI made with the International Ultravi…
Deuterium toward the WD0621-376 sight line: Results from the Far Ultraviolet Spectroscopic Explorer (FUSE) Mission
N. Lehner, C. Gry, K. R. Sembach +5
Far Ultraviolet Spectroscopic Explorer observations are presented for WD0621-376, a DA white dwarf star in the local interstellar medium (LISM) at a distance of about 78 pc. The da…
Star Formation, Metallicity and Dust Properties Derived from the SAPM Galaxy Survey Spectra
S. Charlot, G. Kauffmann, M. Longhetti +4
We have derived star formation rates (SFRs), gas-phase oxygen abundances and effective dust absorption optical depths for a sample of galaxies drawn from the Stromlo-APM redshift s…
Constraints on Omega_B from the nucleosynthesis of 7Li in the standard Big Bang
Alain Coc, Elisabeth Vangioni-Flam, Michel Cass'e +1
We update Standard Big Bang Nucleosynthesis (SBBN) calculations on the basis of recent nuclear physics compilations (NACRE in particular), experimental and theoretical works. By a…
Radio AGN Surveys
Carlos De Breuck, Wil van Breugel, Huub Rottgering +1
We present a short overview of radio surveys for AGN, including the `complete' flux limited surveys and `filtered' surveys. We also describe our ultra-steep spectrum search for the…
Dust Polarization From Starlight Data
Pablo Fosalba, Alex Lazarian, Simon Prunet +1
We present a statistical analysis of the interstellar medium (ISM) polarization from the largest compilation available of starlight data, which comprises ~ 5500 stars. The measured…
Polarized Microwave Emission from Dust
A. Lazarian, S. Prunet
Polarized emission from dust is an important foreground that can hinder the progress in polarized CMB studies unless carefully accounted for. We discuss potential difficulties asso…
FUSE Observations of Possible Infalling Planetesimals in the 51 Ophiuchi Circumstellar Disk
A. Roberge, P. D. Feldman, A. Lecavelier des Etangs +5
We present the first observations of the circumstellar (CS) disk system 51 Ophiuchi with the Far Ultraviolet Spectroscopic Explorer. We detect several absorption lines arising from…
Tracing Matter with Weak Lensing Surveys
Y. Mellier, L. van Waerbeke
Gravitational weak lensing maps the location of (dark) matter at all scales. The lens-induced distortion field traces gravity fields and can be used to reconstruct the mass distrib…
Conservation laws for collisions of branes (or shells) in general relativity
David Langlois, Kei-ichi Maeda, David Wands
We consider the collision of self-gravitating n-branes in a (n+2)-dimensional spacetime. We show that there is a geometrical constraint which can be expressed as a simple sum rule…
