    • Outer-disk reddening and gas-phase metallicities: The CALIFA connection 
      Marino, R.; Gil de Paz, A.; Sánchez, S.; Sánchez Blázquez, P.; Cardiel, N.; Castillo Morales, A.; Pascual, S.; Vilchez, J.; Kehrig, C.; Molla, M.; Méndez Abreu, J.; Catalán Torrecilla, C.; Florido, E.; Pérez, I.; Ruiz Lara, T.; Ellis, S.; López Sánchez, Ángel R.; González Delgado, R. M.; Lorenzo Cáceres, A. de; García Benito, R.; Galbany, Lluis; Zibett, S.; Cortijo, C.; Kalinova, V.; Mast, D.; Iglesias Paramo, J.; Papaderos, P.; Walcher, C.; Bland Hawthorn, J. (EDP SCIENCES, 2016)
      We study, for the first time in a statistically significant and well-defined sample, the relation between the outer-disk ionized-gas metallicity gradients and the presence of breaks in the surface brightness profiles of ...
    • Spectroscopic aperture biases in inside-out evolving early-type galaxies from CALIFA 
      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.; Garcia Benito, R.; Marquez, I.; Olmo, A. del; Molla, M.; Marino, R.; Catalán Torrecilla, C.; González Delgado, R.; López Sánchez, Ángel R. (EDP SCIENCES, 2016)
      Integral field spectroscopy (IFS) studies based on CALIFA survey data have recently revealed ongoing low-level star formation (SF) in the periphery of a small fraction (similar to 10%) of local early-type galaxies (ETGs), ...
    • 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.; Olmo, A. del; 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 ...
