A Multiple System of Radio Sources at the Core of the L723 Multipolar Outflow
Carlos Carrasco-Gonzalez, Guillem Anglada, Luis F. Rodriguez +3
We present high angular resolution Very Large Array multi-epoch continuum observations at 3.6 cm and 7 mm towards the core of the L723 multipolar outflow revealing a multiple syste…
Dynamical Casimir Effect with Semi-Transparent Mirrors, and Cosmology
Emilio Elizalde
After reviewing some essential features of the Casimir effect and, specifically, of its regularization by zeta function and Hadamard methods, we consider the dynamical Casimir effe…
Zeta Function Methods and Quantum Fluctuations
Emilio Elizalde
A review of some recent advances in zeta function techniques is given, in problems of pure mathematical nature but also as applied to the computation of quantum vacuum fluctuations…
Gravitational settling of 22Ne and white dwarf evolution
E. García--Berro, L. G. Althaus, A. H. Córsico +1
We study the effects of the sedimentation of the trace element 22Ne in the cooling of white dwarfs. In contrast with previous studies, which adopted a simplified treatment of the e…
Perturbations of Schwarzschild Black Holes in Chern-Simons Modified Gravity
Nicolas Yunes, Carlos F. Sopuerta
We study perturbations of a Schwarzschild black hole in Chern-Simons modified gravity. We begin by showing that Birkhoff's theorem holds for a wide family of Chern-Simons coupling…
A Three-Dimensional Picture of the Delayed-Detonation Model of Type Ia Supernovae
Eduardo Bravo, Domingo Garcia-Senz
Deflagration models poorly explain the observed diversity of SNIa. Current multidimensional simulations of SNIa predict a significant amount of, so far unobserved, carbon and oxyge…
Fundamental properties of low-mass stars
I. Ribas, J. Morales, C. Jordi +3
Numerous investigations on the fundamental properties of low-mass stars using eclipsing binaries indicate a strong discrepancy between theory and observations that is still awaitin…
The effect of activity on stellar temperatures and radii
J. C. Morales, I. Ribas, C. Jordi
Recent analyses of low-mass eclipsing binary stars have unveiled a significant disagreement between the observations and the predictions of stellar structure models. Results show t…
Optical flares from the faint mid-dM star 2MASS J00453911+4140396
Zs. Kővári, F. Vilardell, I. Ribas +4
We present and light curves of a large stellar flare obtained with the Wide Field Camera at the Isaac Newton 2.5-m telescope (La Palma). The source object is a faint ($m_V=…
WD0433+270: an old Hyades stream member or an Fe-core white dwarf?
S. Catalan, I. Ribas, J. Isern +1
G39-27/289 is a common proper motion pair formed by a white dwarf (WD0433+270) and a main-sequence star (BD+26 730) that apparently has been classified as a member of the Hyades op…
The initial-final mass relationship from white dwarfs in common proper motion pairs
S. Catalan, J. Isern, E. Garcia-Berro +3
The initial-final mass relationship of white dwarfs, which is poorly constrained, is of paramount importance for different aspects in modern astrophysics. From an observational per…
Detailed Spectral Modeling of a 3-D Pulsating Reverse Detonation Model: Too Much Nickel
E. Baron, David J. Jeffery, David Branch +3
We calculate detailed NLTE synthetic spectra of a Pulsating Reverse Detonation (PRD) model, a novel explosion mechanism for Type Ia supernovae. While the hydro models are calculate…
Thermal diagnostic of the Optical Window on board LISA Pathfinder
M. Nofrarias, A. F. Garcia Marin, A. Lobo +4
Vacuum conditions inside the LTP Gravitational Reference Sensor must comply with rather demanding requirements. The Optical Window (OW) is an interface which seals the vacuum enclo…
Dynamical Casimir Effect and the Black Body Spectrum
Jaume Haro, Emilio Elizalde
Creation of scalar massless particles in two-dimensional Minkowski space-time--as predicted by the dynamical Casimir effect--is studied for the case of a semitransparent mirror ini…
Multiple Sources toward the High-mass Young Star S140 IRS1
M. A. Trinidad, J. M. Torrelles, L. F. Rodriguez +1
S140 IRS1 is a remarkable source where the radio source at the center of the main bipolar molecular outflow in the region is elongated perpendicular to the axis of the outflow, an…
De Sitter cosmology from Gauss-Bonnet dark energy with quantum effects
Emilio Elizalde, John Quiroga Hurtado, Hector Ivan Arcos
A Gauss-Bonnet dark energy model is considered, which is inspired in string/M-theory and takes also into account quantum contributions. Those are introduced from a conformal quantu…
Probing quantum gravity using photons from a flare of the active galactic nucleus Markarian 501 observed by the MAGIC telescope
J. Albert et al., John Ellis, N. E. Mavromatos +3
We analyze the timing of photons observed by the MAGIC telescope during a flare of the active galactic nucleus Mkn 501 for a possible correlation with energy, as suggested by some…
The Sloan Digital Sky Survey Quasar Lens Search. II. Statistical Lens Sample from the Third Data Release
Naohisa Inada, Masamune Oguri, Robert H. Becker +31
We report the first results of our systematic search for strongly lensed quasars using the spectroscopically confirmed quasars in the Sloan Digital Sky Survey (SDSS). Among 46,420…
The Sloan Digital Sky Survey Quasar Lens Search. III. Constraints on Dark Energy from the Third Data Release Quasar Lens Catalog
Masamune Oguri, Naohisa Inada, Michael A. Strauss +31
We present cosmological results from the statistics of lensed quasars in the Sloan Digital Sky Survey (SDSS) Quasar Lens Search. By taking proper account of the selection function,…
The Fifth Data Release of the Sloan Digital Sky Survey
Jennifer K. Adelman-McCarthy
This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through June 2005 and represents the completion…
A comprehensive study of Cepheid variables in the Andromeda galaxy. Period distribution, blending and distance determination
F. Vilardell, C. Jordi, I. Ribas
Extragalactic Cepheids are the basic rungs of the cosmic distance scale. They are excellent standard candles, although their luminosities and corresponding distance estimates can b…
The contribution of Oxygen-Neon white dwarfs to the MACHO content of the Galactic Halo
J. Camacho, S. Torres, J. Isern +2
The interpretation of microlensing results towards the Large Magellanic Cloud (LMC) still remains controversial. White dwarfs have been proposed to explain these results and, hence…
