A study of the neglected Galactic HII region NGC 2579 and its companion ESO 370-9
M. V. F. Copetti, V. A. Oliveira, R. Riffel +2
The Galactic HII region NGC 2579 has stayed undeservedly unexplored due to identification problems which persisted until recently. Both NGC 2579 and its companion ESO 370-9 have be…
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…
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…
