Chemical abundances of Seyfert 2 AGNs I. Comparing oxygen abundances from distinct methods using SDSS
O. L. Dors, P. Freitas-Lemes, E. B. Amores +6
We compare the oxygen abundance (O/H) of the Narrow Line Regions (NLRs) of Seyfert 2 AGNs obtained through strong-line methods and from direct measurements of the electron temperat…
2D kinematic study of the central region of NGC 4501
P. Repetto, M. Faundez-Abans, P. Freitas-Lemes +2
GMOS-IFU observational data were used to study the detailed two dimensional gas kinematics and morphological structures within the ~500x421 pc^2 of the active Seyfert 2 galaxy NGC…
FM 047-02: a collisional pair of galaxies with a ring
M. Faundez-Abans, M. de Oliveira-Abans, A. C. Krabbe +3
Aims. We investigate the nature of the galaxy pair FM 047-02, which has been proposed as an archetype of the Solitaire types of peculiar (collisional) ring galaxies. Methods. The s…
A first study of the galaxy HRG 2304 and its companion AM 1646-795 (NED01)
E. Wenderoth, M. Faundez-Abans, A. C. Krabbe +2
Aims. We report the first study of the peculiar ring-like galaxy HRG 2304 (NED02),which was previously classified as a ring galaxy with an elliptical smooth ring. This object was s…
Testing the Newton second law in the regime of small accelerations
V. A. De Lorenci, M. Faundez-Abans, J. P. Pereira
It has been pointed out that the Newtonian second law can be tested in the very small acceleration regime by using the combined movement of the Earth and Sun around the Galactic ce…
UGC 7388: a galaxy with two tidal loops
M. Faundez-Abans, V. P. Reshetnikov, M. de Oliveira-Abans +1
We present the results of spectroscopic and morphological studies of the galaxy UGC7388 with the 8.1-m Gemini North telescope. Judging by its observed characteristics, UGC7388 is a…
