The ALHAMBRA survey: Evolution of galaxy clustering since z∼1
(Oxford University Press, 2014-06)
We study the clustering of galaxies as function of luminosity and redshift in the range 0.35< z < 1.25 using data from the Advanced Large Homogeneous Area Medium-Band Redshift Astronomical (ALHAMBRA) survey. The ALHAMBRA ...

A large lunar impact blast on September 11th 2013
(Oxford University Press, 2014)
On 2013 September 11 at 20h07m28 .s 68 ± 0 .s 01 UTC, two telescopes operated in the framework of our lunar impact flashes monitoring project recorded an extraordinary flash produced by the impact on the Moon of a large ...

Disentangling phase transitions and critical points in the proton-neutron interacting boson model by catastrophe theory
(Elsevier, 2014)
We introduce the basic concepts of catastrophe theory needed to derive analytically the phase diagram of the proton–neutron interacting boson model (IBM-2). Previous studies [1–3] were based on numerical solutions. We here ...

Near-earth object 2012XJ112 as a source of bright bolides of achondritic nature
(Blackwell Publishing Ltd, 2014)
We analyse the likely link between the recently discovered near-Earth object 2012XJ112 and a bright fireball observed over the south of Spain on 2012 December 27. The bolide, with an absolute magnitude of -9 ± 1, was ...

Charged-current quasielastic neutrino scattering cross sections on 12 C with realistic spectral and scaling functions
(American Physical Society, 2014)
Charge-current quasielastic (anti)neutrino scattering cross sections on a 12C target are analyzed using a spectral function S(p,E) that gives a scaling function in accordance with the (e,e′) scattering data. The spectral ...

On the kinetic and thermodynamic electron temperatures in non-thermal plasmas
(IOP Publishing Ltd., 2014)
The framework to describe the out-of-equilibrium free electrons in cold plasmas is developed assuming the electron entropy is defined through the Boltzmann H-theorem. Our theory explains why the Saha-Boltzmann relation ...

Astrophysical reaction rate for 9 Be formation within a three-body approach
(American Physical Society, 2014)
The structure of the Borromean nucleus 9Be (α+α+n) is addressed within a three-body approach using the analytical transformed harmonic oscillator method. The three-body formalism provides an accurate description of the ...

Bright fireballs associated with the potentially hazardous asteroid 2007LQ19
(Oxford University Press, 2014)
We analyse here two very bright fireballs produced by the ablation in the atmosphere of two large meteoroids in 2009 and 2010. These slow-moving and deep-penetrating events were observed over Spain in the framework of our ...

The one nucleon transfer operator in the microscopic IBM without NOA
(Elsevier, 2014)
The mapping of the single fermion creation operator (ci†) onto the Interacting Boson-Fermion space (IBFM) is revisited within the Generalized Seniority scheme. In the original work the Number Operator Approximation (NOA) ...
