The Connection between Star-forming Galaxies, Agn Host Galaxies and Early-type Galaxies in the Sdss
We present a study of the connection between star-forming galaxies, AGN host galaxies, and normal early-type galaxies in the Sloan Digital Sky Survey (SDSS). Using the SDSS DR5 and DR4plus data, we select our early-type galaxy sample in the color versus color-gradient space, and we classify the spectral types of the selected early-type galaxies into normal, star-forming, Seyfert, and LINER clas...

We present a study of the connection of star-forming galaxies, AGN host galaxies, and normal earlytype galaxies in the Sloan Digital Sky Survey (SDSS). Using the SDSS DR5 and DR4plus data, we select our early-type galaxy sample in the color vs. color-gradient space, and classify the spectral types of the selected early-type galaxies into normal, star-forming, Seyfert and LINER classes, using se...
متن کاملThe host galaxy / AGN connection in nearby early - type galaxies ⋆ . Is there a miniature radio - galaxy in every “ core ” galaxy ?
This is the second of a series of three papers exploring the connection between the multiwavelength properties of AGN in nearby early-type galaxies and the characteristics of their hosts. We selected two samples with 5 GHz VLA radio flux measurements down to 1 mJy, reaching levels of radio luminosity as low as 10 erg s. In Paper I we presented a study of the surface brightness profiles for the ...
متن کاملThe Σ − L Correlation in Nearby Early-type Galaxies
Early-type galaxy velocity dispersions and luminosities are correlated. The correlation estimated in local samples (≤ 100 Mpc) differs from that measured more recently in the SDSS. We show that this is also true for the ENEAR sample if galaxy luminosities are estimated using distances which have been corrected for peculiar motions. We then show that, because the estimate of the ‘true’ distance ...
متن کاملRecent Star Formation in Nearby Early-type Galaxies
Motivated by recent progress in the study of early-type galaxies owing to technological advances, the launch of new space telescopes and large ground-based surveys, we attempt a short review of our current understanding of the recent star-formation activity in such intriguing galactic systems.
