Title: The peculiar(?) case of [BHF2008] 19  -  an extremely compact and 
massive elliptical galaxy

Abstract:
We investigate the case of the allegedly peculiar galaxy [BHF2008] 19 (short 
b19). It is very compact elliptical galaxy with an outstandingly high central 
velocity dispersion. This galaxy is believed to have either an extraordinarily 
massive central black hole or an unusual initial mass function (IMF). We try to 
find more galaxies with similar overall properties to provide a large sample 
for further studies. Therefore, we select define a sample of about 50 galaxies 
consisting the most compact and most massive (highest central velocity 
dispersion) of more than 100000 SDSS galaxies which were classified by 
GalaxyZoo to be early type. We study how well these galaxies fit on well-known 
relations of elliptical galaxies such as the fundamental plane or the red 
sequence. We also use Sersic fits in addition to the de Vaucouleurs fits 
provided by SDSS in order to better understand possible peculiarities of the 
global parameters of these galaxies. Our investigation yields that b19 is not 
unique and that b19-like objects just form the most massive and most compact 
tail of the general distribution of elliptical galaxies and that they are that 
distinct after all. The main objective of this work is to establish the correct 
framework for understanding b19 and similar galaxies.
