Kinematics and physical properties of Southern interacting galaxies: the minor merger AM 2306-721
A. C. Krabbe, M. G. Pastoriza, Claudia Winge +2
We present an observational study about the effects of the interactions in the kinematics, stellar population and abundances of the components of the galaxy pair AM2306-721. Rotati…
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…
Star formation, metallicity gradient and ionized gas: clues to the formation of the elliptical galaxies NGC6868 and NGC5903
Mauro G. Rickes, Miriani G. Pastoriza, Charles Bonatto
The stellar population, metallicity distribution and ionized gas in the elliptical galaxies NGC 6868 and NGC 5903 are investigated in this paper by means of long-slit spectroscopy…
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…
High resolution imaging of the early-type galaxy NGC 1380: an insight into the nature of extended extragalactic star clusters
A. L. Chies-Santos, B. X. Santiago, M. G. Pastoriza
NGC 1380 is a lenticular galaxy located near the centre of the Fornax Cluster northeast of NGC 1399. The globular cluster system of this galaxy was previously studied only from the…
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…
