Barrio Uña, Juan Abel ; Bonnefoy, Simon Francois Albert ; Contreras González, José Luis ; Dominguez, A. ; Fidalgo, D. ; Fonseca González, Mª Victoria ; López, M. ; Rosillo Nievas, Mirella ; otros, ... | IOP publishing ltd | 2017-01-01Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars simultaneously at different wavelengths, especially in the X-ray and gamma-ray bands,[...]![]()

Aranda, V. M. ; Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado, J. ; Vázquez Peñas, José Ramón | IOP publishing ltd | 2015-05-01We analyze the distribution of arrival directions of ultra-high-energy cosmic rays recorded at the Pierre Auger Observatory in 10 years of operation. The data set, about three times larger than that used in earlier studies, includes arrival dire[...]![]()

Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Scapin, Valeria | IOP publishing ltd | 2011-06We report the results of the observation of the nearly satellite galaxy Segue 1 performed by the MAGIC-I ground-based gamma-ray telescope between November 2008 and March 2009 for a total of 43.2 hours. No significant gamma-ray emission was found[...]![]()

Piqueras de Noriega, Javier ; Fernández Sánchez, Paloma ; Ortega Villafuerte, Yanicet | IOP publishing ltd | 2011-08Al-doped ZnO nanorod networks and other microstructures have been grown by a thermal evaporation–deposition method with a mixture of ZnS and Al_2O_3 powders as precursor. Some of the grown structures consist of star-like arrays of nanorods arran[...]![]()

An iterative algorithm for determining a class of solutions of the dispersionful 2-Toda hierarchy characterized by string equations is developed. This class includes the solution which underlies the large N-limit of the Hermitian matrix model in[...]![]()

Gómez Gómez, José María ; Faleiro, E. ; Muñoz, L. ; Molina, R. A. ; Relaño Pérez, Armando | IOP publishing ltd | 2015Shell-model calculations with realistic empirical interactions constitute an excellent tool to study statistical properties of nuclei. Using large-scale shell-model calculations in pf-shell nuclei, we study how the onset of chaos depends on diff[...]![]()

A discretized form of the one-dimensional Dirac equation is solved to study relativistic band structures. Properties of periodic continued fractions are used to find the dispersion relation inside allowed bands. The Mathieu potential is consider[...]![]()

Ivanov, Peter A. ; Porras Torres, Diego ; Ivanov, Svetoslav S. ; Schmidt-Kaler, Ferdinand | IOP publishing ltd | 2013-05-28We study theoretically the collective E circle times e Jahn-Teller-Dicke distortion in a system of trapped ions. In a previous work (Porras et al 2012 Phys. Rev. Lett. 108 235701) we have focused on cooperative Jahn-Teller models consisting of a[...]![]()

Cassatella-Contra, Giovanni A ; Mañas Baena, Manuel ; Tempesta, Piergiulio | IOP publishing ltd | 2014-09We study the analytic properties of a matrix discrete system introduced by Cassatella and Manas (2012 Stud. Appl. Math. 128 252-74). The singularity confinement for this system is shown to hold generically, i.e. in the whole space of parameters [...]![]()

Hidalgo Alcalde, Pedro ; Méndez Martín, Bianchi ; Piqueras de Noriega, Javier | IOP publishing ltd | 2008-11-12Sn doped GeO_2 nanowires and microwires have been grown by an evaporation-deposition method, using a mixture of Ge and SnO_2 powders as precursors. Comparison with undoped GeO_2 nanowires grown by the same method shows that the presence of Sn pr[...]![]()

The class of solvable Lie algebras with an N-graded nilradical of maximal nilpotency index is classified. It is shown that such solvable extensions are unique up to isomorphism. The generalized Casimir invariants for the N-graded nilradicals and[...]![]()

Ruiz Cembranos, José Alberto ; Dobado González, Antonio ; López Maroto, Antonio | IOP publishing ltd | 2007-06-22In this work, we will review the main properties of braneworld models with low tension. Starting from very general principles, it is possible to obtain an effective action for the relevant degrees of freedom at low energies (branons). Using the [...]![]()
