Electron temperature fluctuations in NGC 346
V. A. Oliveira, M. V. F. Copetti, A. C. Krabbe
The existence and origin of large spatial temperature fluctuations in HII regions and planetary nebulae are assumed to explain the differences between the heavy element abundances…
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…
Elusive Active Galactic Nuclei
R. Maiolino, A. Comastri, R. Gilli +8
A fraction of active galactic nuclei do not show the classical Seyfert-type signatures in their optical spectra, i.e. they are optically "elusive". X-ray observations are an optima…
