Probing the near infrared stellar population of Seyfert galaxies
R. Riffel, M. G. Pastoriza, A. Rodriguez-Ardila +1
We employ IRTF SpeX NIR (0.8-2.4 microns) spectra to investigate the stellar population (SP), active galactic nuclei (AGN) featureless continuum (FC) and hot dust properties in 9 S…
The Stellar Populations of Starburst Galaxies Through near infrared spectroscopy
R. Riffel, M. G. Pastoriza, A. Rodriguez-Ardila +1
We study the central (inner few hundred parsecs) stellar populations of four starburst galaxies (NGC34, NGC1614, NGC3310 and NGC7714) in the near-infrared (NIR), from 0.8 to 2.4mic…
The first detection of near-infrared CN bands in active galactic nuclei: signature of star formation
R. Riffel, M. G. Pastoriza, A. Rodriguez-Ardila +1
We present the first detection of the near-infrared CN absorption band in the nuclear spectra of active galactic nuclei (AGN). This feature is a recent star formation tracer, being…
Outflows of very ionized gas in the center of Seyfert galaxies: kinematics and physical conditions
Alberto Rodriguez-Ardila, M. A. Prieto, S. Viegas +1
Mid-resolution spectra are used to deduce the size and kinematics of the coronal gas in a sample of Seyfert galaxies by means of observations of the [FeXI], [FeX], [FeVII], [SiVI]…
A 0.8-2.4 microns spectral atlas of Active Galactic Nuclei
R. Riffel, A. Rodriguez-Ardila, M. G. Pastoriza
Aims: We present a near-infrared spectral atlas of 47 active galactic nuclei (AGN), of all degrees of activity, in the wavelength interval of 0.8-2.4 microns, including the fluxes…
The near-infrared spectrum of Mrk 1239: direct evidence of the dusty torus?
A. Rodriguez-Ardila, X. Mazzalay
We report 0.8-4.5 micron SpeX spectroscopy of the narrow-line Seyfert 1 galaxy Mrk1239. The spectrum is outstanding because the nuclear continuum emission in the near-infrared is d…
