El exilio a México de los marinos de la armada de la II República Española

2018

Este artículo es el resultado de un estudio sobre el grupo de marinos de la Armada de la II República que, tras marchar al exilio en 1939, reemigraron a México. El exilio a México es una emigración tradicionalmente vinculada a personalidades intelectuales. Sin embargo, la mayoría fueron exiliados de a pie y constituye un colectivo poco conocido. Los marinos de la Armada se enmarcan en este grupo y su estudio puede contribuir a una aproximación a esta parte casi olvidada del exilio republicano a México.

Search for Neutrinoless Quadruple-β Decay of 150Nd with the NEMO-3 Detector

2017

We report the results of a first experimental search for lepton number violation by four units in the neutrinoless quadruple-β decay of 150Nd using a total exposure of 0.19 kg yr recorded with the NEMO-3 detector at the Modane Underground Laboratory. We find no evidence of this decay and set lower limits on the half-life in the range T1/2>(1.1–3.2)×10^21  yr at the 90% C.L., depending on the model used for the kinematic distributions of the emitted electrons. peerReviewed

Search for sterile neutrinos with one year of IceCube data

2016

The IceCube neutrino telescope at the South Pole has measured the atmospheric muon neutrino spectrum as a function of zenith angle and energy to search for the oscillation signatures of light sterile neutrinos. The primary result of this search derives from the first year of data, taken during 2011, of the full 86-string IceCube configuration.

Neutrino-nucleus scattering off 136Xe

2015

Background: Theoretical estimates of the cross sections for the neutrino-nucleus scattering off relevant nuclei for supernova neutrinos are essential for many applications in neutrino physics and astrophysics. The double- β-decaying nucleus 136Xe nucleus is used by the EXO Collaboration in the search for neutrinoless double-β decay. A ton-scale experiment based on 136Xe could also be used for studies of supernova neutrinos and/or solar neutrinos. Purpose: The purpose of the present work is, thus, to perform a study of the charged-current and neutral-current nuclear responses to supernova neutrinos for 136Xe. Method: The cross sections are computed by using the well-established framework for…

Nuclear structure and neutrino-nucleus reactions at supernova energies

2015

Supernova-(anti-)neutrino–nucleus scattering is discussed with reference to neutral-current (NC) and charged-current (CC) processes in heavy stable nuclei. The Donnelly-Walecka method with the associated multipole expansion of the nucleonic current has been adopted as the basic framework in deriving the neutrino-nucleus scattering cross sections. The needed nuclear wave functions are computed by using the quasiparticle random-phase approximation (QRPA) for the even-even target nuclei in the NC processes and the proton-neutron QRPA (pnQRPA) has been used to compute the CC processes for the mentioned nuclei. The wave functions of the stable odd-mass target nuclei have been obtained by the use…

Solar neutrino spectroscopy in Borexino

2018

International audience; In more than ten years of operation, Borexino has performed a precision measurement of the solar neutrino spectrum, resolving almost all spectral components originating from the proton-proton fusion chain. The presentation will review the results recently released for the second data taking phase 2012–2016 during which the detector excelled by its unprecedentedly low background levels. New results on the rate of pp, 7Be, pep and 8B neutrinos as well as their implications for solar neutrino oscillations and metallicity are discussed.

New orbital ephemerides for the dipping source 4U 1323-619: Constraining the distance to the source

2016

4U 1323-619 is a low mass X-ray binary system that shows type I X-ray bursts and dips. The most accurate estimation of the orbital period is 2.941923(36) hrs and a distance from the source that is lower than 11 kpc has been proposed. We aim to obtain the orbital ephemeris, the orbital period of the system, as well as its derivative to compare the observed luminosity with that predicted by the theory of secular evolution. We took the advantage of about 26 years of X-ray data and grouped the selected observations when close in time. We folded the light curves and used the timing technique, obtaining 12 dip arrival times. We fit the delays of the dip arrival times both with a linear and a quad…
