Fecha de publicación: | 2015 | Editor: | Indian Academy of Sciences | Citación: | Journal of Astrophysics and Astronomy 36: 457- 465 (2015) | Resumen: | We present a new spectroscopic sample of 11 quasars at intermediate redshift observed with the Infrared Spectrometer and Array Camera (ISAAC) on the ESO Very Large Telescope (VLT), covering O i λ8446 and the Ca ii triplet 8498, 8542, 8662. The new observations – that supplement the sample presented by Martínez-Aldama et al. (2015) – allow us to confirm the constraints on physical conditions and location of the region emitting the low ionization lines, as well as the relation between Ca ii and Fe ii. | Versión del editor: | http://dx.doi.org/10.1007/s12036-015-9354-9 | URI: | http://hdl.handle.net/10261/133336 | DOI: | 10.1007/s12036-015-9354-9 | ISSN: | 0973-7758 |
