    • Integral-Field Stellar and Ionized Gas Kinematics of Peculiar Virgo Cluster Spiral Galaxies 
      Cortés López, Juan; Kenney, Jeffrey; Hardy Raskovan, Eduardo (American Astronomical Society, 2015)
      We present the stellar and ionized gas kinematics of 13 bright peculiar Virgo cluster galaxies observed with the DensePak Integral Field Unit at the WIYN 3.5m telescope in order to look for kinematic evidence that ...
    • Multiple chemodynamic stellar populations of the Ursa Minor dwarf spheroidal galaxy 
      Pace, Andrew B.; Kaplinghat, Manoj; Kirby, Evan; Simon, Joshua D.; Tollerud, Erik; Muñoz Vidal, Ricardo Rodrigo; Côte, Patrick; Djorgovski, S. G.; Geha, Marla (Oxford University Press, 2020)
      We present a Bayesian method to identify multiple (chemodynamic) stellar populations in dwarf spheroidal galaxies (dSphs) using velocity, metallicity, and positional stellar data without the assumption of spherical symmetry. ...
    • Near-infrared spectroscopic observations of high redshift C I absorbers 
      Zou, Siwei; Petitjean, Patrick; Noterdaeme, Pasquier; Ledoux, Cédric; Krogager, J. K.; Fathivavsari, H.; Srianand, R.; López, S. (EDP Sciences, 2018)
      We study a sample of 17 $z>1.5$ C~{\sc i} absorbers observed with the ESO-VLT spectrograph X-SHOOTER. We derive metallicities, depletion onto dust, extinction by dust and analyse the absorption from Mg~{\sc ii}, Mg~{\sc ...
    • Warm ionized gas in CALIFA early-type galaxies 2D emission-line patterns and kinematics for 32 galaxies 
      Gomes, J.M.; Papaderos, P.; Kehrig, C.; Vílchez, J. M.; Lehnert, M. D.; Sánchez, S. F.; Ziegler, B.; Breda, I.; dos Reis, S.N.; Iglesias-Páramo, J.; Bland-Hawthorn, J.; Galbany, Lluis; Bomans, D. J.; Rosales-Ortega, F. F.; Cid Fernandes, R.; Walcher, C. J.; Falcón Barroso, J.; García-Benito, R.; Márquez, I.; Olmo, A. del; Masegosa, J.; Mollá, M.; Marino, R. A.; González Delgado, R. M.; López Sánchez, Ángel R. (ESO, 2016-04)
      Context. The morphological, spectroscopic, and kinematical properties of the warm interstellar medium (wim) in early-type galaxies (ETGs) hold key observational constraints to nuclear activity and the buildup history of ...
