Differences between CO- and calcium triplet-derived velocity dispersions in spiral galaxies: evidence for central star formation?
Rogemar A. Riffel, Luis C. Ho, Rachel Mason +16
We examine the stellar velocity dispersions (sigma) of a sample of 48 galaxies, 35 of which are spirals, from the Palomar nearby galaxy survey. It is known that for ultra-luminous…
Modeling the [Fe II]λ1.644μm outflow and comparison with H and H kinematics in the inner 200 pc of NGC 1068
F. K. B. Barbosa, T. Storchi-Bergmann, P. McGregor +1
We map the kinematics of the inner (200 pc) narrow-line region (NLR) of the Seyfert 2 galaxy NGC 1068 using the instrument NIFS and adaptative optics at the Gemini North Telescope.…
Probing the Circumnuclear Stellar Populations of Starburst Galaxies in the Near-infrared
N. Z. Dametto, R. Riffel, M. G. Pastoriza +3
We employ the NASA Infrared Telescope Facility's near-infrared spectrograph SpeX at 0.8-2.4m to investigate the spatial distribution of the stellar populations (SPs) in four wel…
HCO+ and radio continuum emission from the star forming region G75.78+0.34
Rogemar A. Riffel, Everton Ludke
We present 1.3 and 3.6cm radio continuum images and a HCO+ spectrum of the massive star forming region G75.78+0.34 obtained with the Very Large Array (VLA) and with the Berkley Ill…
Spectral Synthesis of Star-forming Galaxies in the Near-Infrared
Lucimara Martins, Alberto Rodríguez-Ardila, Suzi Diniz +2
The near-infrared spectral region is becoming a very useful wavelength range to detect and quantify the stellar population of galaxies. Models are developing to predict the contrib…
Optical and mid-infrared neon abundance determinations in star-forming regions
Oli L. Dors, Guillermo F. Hagele, Monica V. Cardaci +6
We employed observational spectroscopic data of star-forming regions compiled from the literature and photoionization models to analyse the neon ionic abundances obtained using bot…
