What do the Star Formation Histories of Galaxies tell us about the Starburst-AGN connection?
J. P. Torres-Papaqui, R. Coziol, I. Plauchu-Frayn +2
Using a sample of 229618 narrow emission-line galaxies, we have determined the normal star formation histories (SFHs) for galaxies with different activity types: star forming galax…
The star formation histories of Hickson compact group galaxies
I. Plauchu-Frayn, A. del Olmo, R. Coziol +1
ABRIDGED: We study the Star Formation History (SFH) of 210 galaxies members of 55 Hickson Compact Groups (HCG) and 309 galaxies from the Catalog of Isolated Galaxies (CIG). The SFH…
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…
Mass of the black hole in the Seyfert 1.5 galaxy H 0507+164 from reverberation mapping
C. S. Stalin, S. Jeyakumar, R. Coziol +2
We present the results of our optical monitoring campaign of the X-ray source H 0507+164, a low luminosity Seyfert 1.5 galaxy at a redshift z = 0.018. Spectroscopic observations we…
The signature of LLAGNs in the nearby universe
D. M. Neri-Larios, J. P. Torres-Papaqui, R. Coziol +2
We have used the diagnostic diagram that compares the ratio of emission lines [NII]\lambda6584/Hαwith the equivalent width of [NII]6584, as proposed by Coziol et al. (1998), to…
