Quantum inflaton, primordial metric perturbations and CMB fluctuations
F. J. Cao
We compute the primordial scalar, vector and tensor metric perturbations arising from quantum field inflation. Quantum field inflation takes into account the nonperturbative quantu…
A maximally superintegrable system on an n-dimensional space of nonconstant curvature
Angel Ballesteros, Alberto Enciso, Francisco J. Herranz +1
A novel Hamiltonian system in n dimensions which admits the maximal number 2n-1 of functionally independent, quadratic first integrals is presented. This system turns out to be the…
The noncommutative U(1) Higgs-Kibble model in the enveloping-algebra formalism and its renormalizability
C. P. Martin, D. Sanchez-Ruiz, C. Tamarit
We discuss the renormalizability of the noncommutative U(1)Higgs-Kibble model formulated within the enveloping-algebra approach. We consider both the phase of the model with unbrok…
Final-state interactions and superscaling in the semi-relativistic approach to quasielastic electron and neutrino scattering
J. E. Amaro, M. B. Barbaro, J. A. Caballero +2
The semi-relativistic approach to electron and neutrino quasielastic scattering from nuclei is extended to include final-state interactions. Starting with the usual non-relativisti…
Detecting Obscured AGN in the Distant Universe with Spitzer
J. L. Donley, G. H. Rieke, P. G. Perez-Gonzalez +2
We present the results of a Spitzer search for obscured AGN in the Chandra Deep Field-North, using both radio-excess and mid-infrared power-law selection. AGN selected via the form…
Equisingularity at the Normalisation
Javier Fernandez de Bobadilla, Maria Pe Pereira
We look at topological equisingularity of a holomorphic family of reduced mapping germs f_t:(C^3,O)->C over a contractible base T having non-isolated singularities, by means of the…
Dispersive chiral approach to Meson-meson dynamics: Spectroscopy results for light scalars and precision studies
J. R. Pelaez
Dispersive approaches provide model independent description of meson-meson scattering. We first review here the use of dispersion relations to obtain a model independent unitarizat…
The quest for obscured AGN at cosmological distances: Infrared Power-Law Galaxies
Almudena Alonso-Herrero, Jennifer L. Donley, George H. Rieke +2
We summarize multiwavelength properties of a sample of galaxies in the CDF-N and CDF-S whose Spectral Energy Distributions (SEDs) exhibit the characteristic power-law behavior expe…
Viscosity solutions to second order partial differential equations on Riemannian manifolds
Daniel Azagra, Juan Ferrera, Beatriz Sanz
We prove comparison, uniqueness and existence results for viscosity solutions to a wide class of fully nonlinear second order partial differential equations …
Flags in zero dimensional complete intersections and indices of real vector fields
L. Giraldo, X. Gomez-Mont, P. Mardesic
We introduce bilinear forms in a flag in a complete intersection local -algebra of dimension 0, related to the Eisenbud-Levine, Khimshiashvili bilinear form. We give a v…
On the real linear polarization constant problem
Máté Matolcsi, Gustavo A. Muñoz
The present paper deals with lower bounds for the norm of products of linear forms. It has been proved by J. Arias-de-Reyna \cite{ARIAS}, that %for , the so-called $…
Out of equilibrium quantum field dynamics in external fields
F. J. Cao
The quantum dynamics of the symmetry broken λ(Φ^2)^2 scalar field theory in the presence of an homogeneous external field is investigated in the large N limit. We consider an initi…
The Higgs effective potential in the Littlest Higgs model at the one-loop level
Antonio Dobado, Lourdes Tabares-Cheluci, Siannah Penaranda
In this work we compute the contributions to the Higgs effective potential coming from the fermion and gauge boson sectors at the one-loop level in the context of the SU(5)/SO(5) L…
MAGIC upper limits on the very high energy emission from GRBs
J. Albert, E. Aliu, H. Anderhub +57
The fast repositioning system of the MAGIC Telescope has allowed during its first data cycle, between 2005 and the beginning of year 2006, observing nine different GRBs as possible…
Signal Reconstruction for the MAGIC Telescope
J. Albert
Until April 2007 the MAGIC telescope used a 300 MSamples/s FADC system to sample the shaped PMT signals produced by the captured Cherenkov photons of air showers. Different algorit…
Observation of very high energy gamma-rays from the AGN 1ES 2344+514 in a low emission state with the MAGIC telescope
J. Albert et al.
The MAGIC collaboration has observed very high energy gamma ray emission from the AGN 1ES 2344+514. A gamma-ray signal corresponding to an 11 sigma excess and an integral flux of (…
Specific SFR profiles in nearby spiral galaxies: quantifying the inside-out formation of disks
J. C. Muñoz-Mateos, A. Gil de Paz, S. Boissier +4
We present specific Star Formation Rate (sSFR) radial profiles for a sample of 161 relatively face-on spiral galaxies from the GALEX Atlas of Nearby Galaxies. The sSFR profiles are…
Statistical Properties of the GALEX/SDSS matched source catalogs, and classification of the UV sources
Luciana Bianchi, Lino Rodriguez-Merino, Maurice Viton +30
We use the Galaxy Evolution Explorer (GALEX) Medium and All-Sky-Imaging Survey (MIS & AIS) data from the first public data release (GR1), matched to the Sloan Digital Sky Survey (S…
First bounds on the very high energy gamma-ray emission from Arp 220
J. Albert et al.
Using the Major Atmospheric Gamma Imaging Cherenkov Telescope (MAGIC), we have observed the nearest ultra-luminous infrared galaxy Arp 220 for about 15 hours. No significant signal…

Microcanonical Approach to the Simulation of First-Order Phase Transitions
V. Martin-Mayor
A generalization of the microcanonical ensemble suggests a simple strategy for the simulation of first order phase transitions. At variance with flat-histogram methods, there is no…
