The nature and origin of Narrow Line AGN activity in a sample of isolated SDSS galaxies
R. Coziol, J. P. Torres-Papaqui, I. Plauchu-Frayn +4
We discuss the nature and origin of the nuclear activity observed in a sample of 292 SDSS narrow-emission-line galaxies, considered to have formed and evolved in isolation. All the…
Narrow-Line AGNs: confirming the relationship between metallicity and accretion rate
D. M. Neri-Larios, R. Coziol, J. P. Torres-Papaqui +4
We have selected a sample of 292 SDSS Narrow-Emission-Line galaxies known to have formed and evolved in relative isolation to study the nature and origin of the AGN phenomenon. The…
Relation between activity, morphology and environment for a large sample of SDSS galaxies
R. A. Ortega-Minakata, J. P. Torres-Papaqui, H. Andernach +2
We apply a stellar population synthesis code to the spectra of a large sample of SDSS galaxies to classify these according to their activity (using emission-line diagnostic diagram…
Low Luminosity AGN candidates in SDSS
J. P. Torres-Papaqui, R. Coziol, J. M. Islas-Islas +2
In a sample of 476931 NELGs obtained from the SDSS DR5 data we find that in 22% of the galaxies the emission line [OIII]5007, H, or both, are missing. The nature of the activ…
Galaxy activity influenced by the environment in the cluster of galaxies Abell 85
C. A. Caretta, J. M. Islas-Islas, J. P. Torres-Papaqui +3
We analyse the relation between the dynamical state of a cluster of galaxies and the activity (star formation and AGN) of its members. For the case of Abell 85 we find some evidenc…
The HI Parkes Zone of Avoidance Survey: the Northern Extension
J. L. Donley, L. Staveley-Smith, R. C. Kraan-Korteweg +6
We present the results of the northern extension of the HI Parkes Zone of Avoidance Survey, a blind HI survey utilizing the multibeam receiver on the Parkes 64-m telescope. In the…
