The GALANTE Photometric System
This paper describes the characterization of the GALANTE photometric system,
a seven intermediate- and narrow-band filter system with a wavelength coverage
from 3000 to 9000 . We describe the photometric system
presenting the full sensitivity curve as a product of the filter sensitivity,
CCD, telescope mirror, and atmospheric transmission curves, as well as some
first- and second-order moments of this sensitivity function. The GALANTE
photometric system is composed of four filters from the J-PLUS photometric
system, a twelve broad-to-narrow filter system, and three exclusive filters,
specifically designed to measure the physical parameters of stars such as
effective temperature , , metallicity, colour excess
, and extinction type . Two libraries, the Next
Generation Spectral Library (NGSL) and the one presented in Ma\'iz Apell\'aniz
& Weiler (2018), have been used to determine the transformation equations
between the Sloan Digital Sky Survey ()
photometry and the GALANTE photometric system. We will use this transformation
to calibrate the zero points of GALANTE images. To this end, a preliminary
photometric calibration of GALANTE has been made based on two different
libraries ( DR12 and ATLAS All-Sky Stellar
Reference Catalog, hereinafter ). A comparison between both
zero points is performed leading us to the choice of as the
base catalogue for this calibration, and applied to a field in the Cyg OB2
association.Comment: Accepted in MNRA
Investigating Yang-Mills theory and Confinement as a function of the spatial volume
We study the volume dependence of electric flux energies for SU(2) gauge
theory with twisted boundary conditions. The curves interpolate smoothly
between the perturbative semiclassicalresults and the Confinement regime. On
the basis of our results, we propose that the Confinement property might be
caused by a class of non-dilute multi-instanton configurations.Comment: Postscript - paper.ps and sig_lt3c.eps (Fig 1). 25 pages of text and

The GALANTE photometric survey of the northern Galactic plane: Project description and pipeline
The GALANTE optical photometric survey is observing the northern Galactic
plane and some adjacent regions using seven narrow- and intermediate-filters,
covering a total of 1618 square degrees. The survey has been designed with
multiple exposure times and at least two different air masses per field to
maximize its photometric dynamic range, comparable to that of Gaia, and ensure
the accuracy of its photometric calibration. The goal is to reach at least 1%
accuracy and precision in the seven bands for all stars brighter than AB
magnitude 17 while detecting fainter stars with lower values of the
signal-to-noise ratio.The main purposes of GALANTE are the identification and
study of extinguished O+B+WR stars, the derivation of their extinction
characteristics, and the cataloguing of F and G stars in the solar
neighbourhood. Its data will be also used for a variety of other stellar
studies and to generate a high-resolution continuum-free map of the H{\alpha}
emission in the Galactic plane. We describe the techniques and the pipeline
that are being used to process the data, including the basis of an innovative
calibration system based on Gaia DR2 and 2MASS photometry.Comment: 18 pages, accepted for publication in MNRA

La falla de Tíscar: su significado en la terminación sudoeste del arco Prebético
10 páginas, 11 figuras, 1 tabla.[EN] The Tíscar fault, located towards the SW end of the Prebetic arc, is an important feature
within the Betic External Zone which contributed to the separation of two different geologic domains.
This fault affected the Mesozoic and Tertiary cover detached from the Palaeozoic basement and was
developed as consequence of the blockage of the thrust sheets of the western border of the arc, because
they could not advance farther over the basement situated progressively in a shallower position.
Hence, this fault encouraged the continuation of the NW displacements in the western block, formed
by Subbetic olistostromic masses and part of the Prebetic situated in the end of the arc. Although the
Tíscar fault has been defined by one main line, there are in fact other parallel faults that form a broad
fault zone. Its displacement began during the late Miocene and continued till Pliocene, within a near
N-S compressive setting with a perpendicular extension.[ES] La falla de Tíscar, localizada en la terminación SO del arco Prebético, es un rasgo importante
dentro de la Zona Externa Bética, donde ha contribuido a la separación de dos dominios geológicos
diferentes. Esta falla afectó a la cobertera mesozoica y terciaria despegada del basamento paleozoico
y se formó como consecuencia de que los cabalgamientos del borde occidental del arco quedaron
bloqueados al no poder avanzar más sobre el basamento cada vez menos profundo. Entonces la falla
permitió la continuación de los movimientos hacia el NO de su bloque occidental formado por
materiales del Subbético, dispuesto en masas olistostrómicas, e incluso parte del propio Prebético del
extremo del arco. Aunque la falla de Tíscar se ha definido por su traza principal, existen otras paralelas
que en conjunto forman una amplia zona. Sus movimientos iniciados en el Mioceno superior
continuaron hasta el Plioceno, en un contexto de compresión N-S y extensión perpendicular.Este estudio se ha financiado a través de los proyectos

Compilation of parameterized seismogenic sources in Iberia for the SHARE European-scale seismic source model.
Abstract: SHARE (Seismic Hazard Harmonization in Europe) is an EC-funded project (FP7) that aims to evaluate European seismic hazards using an integrated, standardized approach. In the context of SHARE, we are compiling a fully-parameterized active fault database for Iberia and the nearby offshore region. The principal goal of this initiative is for fault sources in the Iberian region to be represented in SHARE and incorporated into the source model that will be used to produce seismic hazard maps at the European scale. The SHARE project relies heavily on input from many regional experts throughout the Euro-Mediterranean region. At the SHARE regional meeting for Iberia, the 2010 Working Group on Iberian Seismogenic Sources (WGISS) was established; these researchers are contributing to this large effort by providing their data to the Iberian regional integrators in a standardized format. The development of the SHARE Iberian active fault database is occurring in parallel with IBERFAULT, another ongoing effort to compile a database of active faults in the Iberian region.
The SHARE Iberian active fault database synthesizes a wide range of geological and geophysical observations on active seismogenic sources, and incorporates existing compilations (e.g., Cabral, 1995; Silva et al., 2008), original data contributed directly from researchers, data compiled from the literature, parameters estimated using empirical and analytical relationships, and, where necessary, parameters derived using expert judgment. The Iberian seismogenic source model derived for SHARE will be the first regional-scale source model for Iberia that includes fault data and follows an internationally standardized approach (Basili et al., 2008; 2009). This model can be used in both seismic hazard and risk analyses and will be appropriate for use in Iberian- and European-scale assessments

Principales fallas activas de las Cuencas de Granada y Guadix-Baza (Cordillera Bética)
The Granada and Guadix-Baza Basins, the largest Neogene-Quaternary intramontane basins of the Betic Cordillera (southern Spain), undergo active deformation with an associated moderate level of seismic activity. This deformation is controlled by a NNWSSE compressive regime and an approximate orthogonal tensional regime. The compression produced N70ºE to E-W folds of several scales, the Sierra Nevada antiform being the largest one. The tension is accommodated mainly by NW-SE active normal faults, the most notable being the Baza Fault, in the Guadix-Baza Basin, and the Granada, Sierra Elvira-Dílar and Padul-Dúrcal Faults, in the Granada Basin. In addition, other active faults with different orientations also exist, such as the Alfahuara-Botardo and the Galera faults in the Guadix-Baza Basin, and the Huenes, Obéilar-Pinos Puente and N of Sierra Tejeda Faults in the Granada Basin. Moreover, in several sectors, the presence of orthogonal normal fault sets suggests alternating trends or even radial extension. Slip rates of these active faults, based on geologic markers, vary between 0.06 and 0.5 mm/year. Estimates for the maximum expected magnitude of earthquakes caused by these faults vary between MW 6.0 and 7.0. The N of Sierra Tejeda and the Baza Faults, the largest faults in the Granada and Guadix-Baza Basins, respectively, have the greatest seismic potential. They could cause events up to a magnitude of MW 6.5-7.0, although their reference earthquakes, computed for a return period of 475 years, are on the order of MW 5.0-5.5.Las Cuencas de Granada y Guadix-Baza, las mayores cuencas intramontañosas del Neógeno y Cuaternario de la Cordillera Bética (sur de España), experimentan una deformación activa y tienen asociada una actividad sísmica moderada. La deformación está controlada por una compresión NNO-SSE y una tensión aproximadamente perpendicular. La compresión ha formado pliegues de dirección N70ºE a E-O de muy diferentes tamaños, siendo el antiforme de Sierra Nevada el mayor. La tensión se acomoda sobre todo por fallas normales NO-SE, siendo las más notables de ellas la falla de Baza, en la cuenca de Guadix-Baza, y las de Granada, Sierra Elvira-Dílar y Padul-Dúrcal, en la cuenca de Granada. Además, existen otras fallas activas con diferentes orientaciones, tales como la de Alfahuara-Botardo y la de Galera en la cuenca de Guadix-Baza y las de Huenes, Obéilar-Pinos Puente y norte de Sierra Tejeda en la cuenca de Granada. Además, en varios sectores, la presencia de juegos de fallas ortogonales sugiere cambios en el elipsoide de esfuerzos e incluso una extensión radial. Las tasas de desplazamiento de estas fallas activas, calculadas a partir de marcadores geológicos, varían entre 0,06 y 0,5 mm/año. La estimación del potencial sísmico indica que la máxima magnitud esperable de los terremotos producidos por estas fallas varía entre MW 6,0 y 7,0. La falla del N de Sierra Tejeda y la de Baza, las mayores respectivamente en las Cuencas de Granada y Guadix-Baza, tienen el mayor potencial sísmico. Podrían causar eventos con magnitudes del orden de MW 6,5-7,0, aunque sus terremotos de referencia para un periodo de retorno de 475 años son del orden de MW 5,0-5,5
