We have searched for off-center nuclei in 78 ``nucleated'' dwarf elliptical (dE,N) galaxies, drawing on digitized photographic images from a previous study of Virgo cluster dwarfs. The search is based on a simple algorithm which compares the center coordinates of a series of outer elliptical ...
(b) the azimuthal pro,le of the opti-cal light of the galaxy.For the latter we created a sample of “optical sources” based on the star-light distribution in the DSS2 R-band image, by randomly drawing posi-tion angles in 2◦ sectors from a,at parent distribution (equivalent to ...
This thesis presents results drawing from three phases in the formation of a typical elliptical: 1) I evaluate how to disentangle AGN from star formation signatures in mid-infrared spectra during a dust-enshrouded starburst, making testable predictions for robustly tracing SMBH growth with the James...
However, it is not clear the extent to which SMBH growth is fueled by these events nor how important is their energy input at setting the appearance of the remnant.;This thesis presents results drawing from three phases in the formation of a typical elliptical: 1) I evaluate how to ...
