      The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey has obtained high-resolution spectra for thousands of red giant stars distributed among the massive satellite galaxies of the Milky Way ...
    • Galaxy clusters in the line of sight to background quasars – II. Environmental effects on the sizes of ... 
      Padilla, Nelson; Lacerna, Iván; López Morales, Sebastián; Barrientos, L. Felipe; Lira Teillery, Paulina; Andrews, Heather; Tejos, Nicolás (2009)
      Based on recent results on the frequency of Mg II absorption-line systems in the spectra of QSO behind RCS clusters (QbC), we analyse the effects of the cluster environment on the sizes of baryonic haloes around galaxies. ...
    • GALAXY CLUSTERS IN THE LINE OF SIGHT TO BACKGROUND QUASARS. III. MULTI-OBJECT SPECTROSCOPY∗ 
      Andrews, H.; Barrientos, L. Felipe; López Morales, Sebastián; Lira Teillery, Paulina; Padilla, N.; Gilbank, D. G.; Lacerna, Iván; Maureira, M. J.; Ellingson, E.; Gladders, M. D.; Yee, H. K. C. (The American Astronomical Society. All rights reserved. Printed in the U.S.A., 2013-09-01)
      We present Gemini/GMOS-S multi-object spectroscopy of 31 galaxy cluster candidates at redshifts between 0.2 and 1.0 and centered on QSO sight lines taken from L´opez et al. The targets were selected based on the presence of ...
