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…
An Interface for the Virtual Observatory of the University of Guanajuato
René A. Ortega-Minakata, Juan P. Torres-Papaqui, Heinz Andernach +1
We present the first attempts to build a user-friendly interface for the Virtual Observatory of the University of Guanajuato. The data tables will be accessible to the public throu…
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…
