López Maroto, Antonio ; Ruiz Cembranos, José Alberto ; Gammaldi, Viviana | IOP publishing ltd | 2013-04We study the main spectral features of the gamma-ray fluxes observed by the High Energy Stereoscopic System (HESS) from the J1745-290 Galactic Center source during the years 2004, 2005 and 2006. In particular, we show that these data are well fi[...]![]()

Bisigello, L. ; Caputi, K.I. ; Colina, L. ; Pérez González, Pablo Guillermo ; Koekemoer, A. ; Le Fèvre, O. ; Grogin, N. ; Norgaard-Nielsen, H.U. ; Van der Werf, P. | IOP publishing ltd | 2019-04Stellar masses in future James Webb Space Telescope (JWST) deep blank fields will be mainly derived by fitting the spectral energy distribution (SED) with theoretical galaxy templates. We investigate the uncertainties and biases of the stellar m[...]![]()

Cornide Castro-Piñeiro, Manuel ; Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Armentia, J. A. ; Reglero, V. | IOP publishing ltd | 1992-04High dispersion spectra have been obtained in order to study the activity level of ten barium stars by means of the Ca II H and K emission flux, looking for a relation between barium intensity index and activity. Absolute magnitudes obtained fro[...]![]()

Llanes Estrada, Felipe José ; Cabrera, Daniel ; Luciano M., Abreu ; Bratkovskaya, Elena ; Ramos, Angels ; Torres Rincón, Juan M. | IOP publishing ltd | 2014We present selected results on the properties of strange and heavy-flavoured mesons in a hot and dense nuclear medium, with emphasis in selfconsistent coupled-channel approaches based on the chiral Lagrangian. In the strangeness sector, we discu[...]![]()

Muñoz San Martín, Sagrario ; Sebastián Franco, José Luis ; Sancho Ruíz, Miguel ; Miranda Pantoja, José Miguel | IOP publishing ltd | 2003-06-07This paper shows the importance of using realistic cell shapes with the proper geometry and orientation to study the mechanisms of direct cellular effects from radiofrequency (RF) exposure. For this purpose, the electric field distribution withi[...]![]()

Mártil de la Plaza, Ignacio ; González Díaz, Germán ; Olea Ariza, Javier ; Prado Millán, Álvaro del | IOP publishing ltd | 2013-12In this work we present the manufacturing processes and results obtained from the characterization of heterojunction with intrinsic thin layer solar cells that include a heavily Ti ion implanted Si absorbing layer. The cells exhibit external cir[...]![]()

Antonov, A. N. ; Gaidarov, M. K. ; Kadrev, D. N. ; Sarriguren, P. ; Moya de Guerra, Elvira | IOP publishing ltd | 2018We derive the volume and surface components of the nuclear symmetry energy (NSE) and their ratio within the coherent density fluctuation model. The estimations use the results of the model for the NSE in finite nuclei based on the Brueckner and [...]![]()
