Title: | Observations of the Ca ii IR Triplet in High Luminosity Quasars: Exploring the Sample | Authors: | Martínez-Aldama, Mary Loli MARZIANI, Paola Dultzin, Deborah Sulentic, Jack W. BRESSAN, Alessandro CHEN, Yang STIRPE, Giovanna Maria |
Issue Date: | 2015 | Journal: | JOURNAL OF ASTROPHYSICS AND ASTRONOMY | Number: | 36 | Issue: | 4 | First Page: | 457 | Abstract: | 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. <P /> | URI: | http://hdl.handle.net/20.500.12386/24200 | URL: | https://link.springer.com/article/10.1007/s12036-015-9354-9 | ISSN: | 0250-6335 | DOI: | 10.1007/s12036-015-9354-9 | Bibcode ADS: | 2015JApA...36..457M | Fulltext: | open |
