    • 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, ...
    • Spectroscopy of the nuclear emission-line regions of the two newly detected Seyfert 1 galaxies F10.01 and A08.12 
      Rodríguez Ardila, Alberto; Pastoriza, Miriani G.; Maza Sancho, José (1998-02-10)
      Long-slit medium-resolution spectra are used to study the continuum and ionization properties of the gas in the Seyfert 1 galaxies F10.01 and A08.12. We Ðnd that the nuclear underlying continuum can be described by a ...
    • The stellar spectral features of nearby galaxies in the near infrared: tracers of thermally pulsing asymptotic ... 
      Riffel, Rogerio; Mason, Rachel; Martins, Lucimara; Rodríguez Ardila, Alberto; Ho, Luis C.; Riffel, Rogemar A.; Lira Teillery, Paulina; González Martín, Omaira; Ruschel Dutra, Daniel; Alonso Herrero, Almudena; Helene, Flohic; McDermid, Richard; Ramos Almeida, Cristina; Thanjavur, Karun; Winge, Claudia (2015)
      We analyse the stellar absorption features in high signal-to-noise ratio (S/N) near-infrared (NIR) spectra of the nuclear region of 12 nearby galaxies, mostly spirals. The features detected in some or all of the galaxies ...
