Evidence of Supermassive Black Holes in Narrow Emission Line Galaxies
J. P. Torres-Papaqui, R. Coziol, H. Andernach +3
A sample of 229618 narrow emission-line galaxies is used to establish two new unambiguous type of evidence for supermassive black holes at the center of their nuclei: 1) the Seyfer…
The star formation history and chemical evolution of star forming galaxies in the nearby universe
J. P. Torres-Papaqui, R. Coziol, R. A. Ortega-Minakata +1
We have determined the O/H and N/O of a sample of 122751 SFGs from the DR7 of the SDSS. For all these galaxies we have also determined their morphology and their SFH using the code…
What makes a galaxy radio-loud?
R. A. Ortega-Minakata, J. P. Torres-Papaqui, H. Andernach +5
We compare the Spectral Energy Distribution (SED) of radio-loud and radio-quiet AGNs in three different samples observed with SDSS: radio-loud AGNs (RLAGNs), Low Luminosity AGNs (L…
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…
