Heath ; Bland-Hawthorn, Joss | EDP Sciencies | 2020-06-25Context. The accurate classification of hundreds of thousands of galaxies observed in modern deep surveys is imperative if we want to understand the universe and its evolution. Aims. Here, we report the use of machine learning techniques to clas[...]texto impreso
Old stellar populations .4. Empirical fitting functions for features in the Spectra of G and K stars
Gorgas García, Francisco Javier ; Faber, S. M. ; Burstein, David ; González, J. Jesús ; Courteau, Stéphane ; Prosser, Charles | University Chicago Press | 1993-05Empirical fitting functions are presented that model the behavior of 11 strong atomic and molecular features in the spectra of Galactic G and K stars. The functions express the strength of spectral features as a function of V - K, surface gravit[...]texto impreso
Ramón-Pérez, Marina ; Bongiovanni, Ángel ; Pérez García, Ana María ; Cepa, Jordi ; Nadolny, Jakup ; Pintos-Castro, Irene ; Lara-López, Maritza A. ; Alfaro, Emilio J. ; Castañeda, Héctor O. ; Cerviño, Miguel ; Diego, José A. ; Fernández-Lorenzo, Mirian ; Gallego Maestro, Jesús ; González, J. Jesús ; González-Serrano, J. Ignacio ; Oteo Gómez, Iván ; Pérez Martínez, Ricardo ; Povic, Mirjana ; Sánchez-Portal, Miguel | EDP Sciencies | 2019-10-14Aims. We take advantage of the capability of the OTELO survey to obtain the H? luminosity function (LF) at z ? 0.40. Because of the deepest coverage of OTELO, we are able to determine the faint end of the LF, and thus better constrain the star f[...]texto impreso

We take advantage of the capabilities of the OSIRIS Tunable Emission Line Object (OTELO) survey to select and study the AGN population in the field. In particular, we aim to perform an analysis of the properties of these objects, including[...]
