    • Differences between CO- and calcium triplet-derived velocity dispersions in spiral galaxies: evidence for ... 
      Riffel, Rogemar A.; Ho, Luis; Mason, Rachel; Rodríguez Ardila, Alberto; Martins, Lucimara; Riffel, Rogerio; Diaz, Ruben; Colina, Luis; Alonso-Herrero, Almudena; Flohic, Helene; González, Omaira; Lira Teillery, Paulina; McDermid, Richard; Ramos Almeida, Cristina; Schiavon, Ricardo; Thanjavur, Karun; Ruschel-Dutra, Daniel; Winge, Claudia; Perlman, Eric (Royal Astronomical Society, 2015)
      We examine the stellar velocity dispersions (σ) of a sample of 48 galaxies, 35 of which are spirals, from the Palomar nearby galaxy survey. It is known that for ultra-luminous infrared galaxies (ULIRGs) and merger remnants, ...
    • Spiral-like star-forming patterns in CALIFA early-type galaxies 
      Gomes, J.; Papaderos, P.; Vilchez, J.; Kehrig, C.; Iglesias Paramo, J.; Breda, I.; Lehnert, M.; Sánchez, S.; Ziegler, B.; dos Reis, S.; Bland Hawthorn, J.; Galbany, Lluis; Bomans, D.; Rosales Ortega, F.; Walcher, C.; García Benito, R.; Marquez, I.; del Olmo, A.; Molla, M.; Marino, R.; Catalan Torrecilla, C.; González Delgado, R. M.; López Sánchez, Ángel R. (EDP SCIENCES, 2016)
      Based on a combined analysis of SDSS imaging and CALIFA integral field spectroscopy data, we report on the detection of faint (24 < mu(r) mag/square" < 26) star-forming spiral-arm-like features in the periphery of three ...
    • Stellar kinematics of the Andromeda II dwarf spheroidal galaxy 
      Ho, Nhung; Geha, M.; Munoz, R. R.; Guhathakurta, P.; Kalirai, J.; Gilbert, K. M.; Tollerud, E.; Bullock, J.; Beaton, R. L.; Majewski, S. R. (Institute of Physics Publishing, 2012)
      We present kinematical profiles and metallicity for the M31 dwarf spheroidal (dSph) satellite galaxy AndromedaII (AndII) based on Keck DEIMOS spectroscopy of 531 red giant branch stars. Our kinematical sample is among the ...
