One possible way for spiral galaxies to internally evolve would be for gas to flow to the center and form stars in a central disk (pseudo-bulge). ... In this paper we present radial profiles of stellar and 8 ЮМm emission from polycyclic aromatic hydrocarbons (PAHs) for 11 spiral galaxies to investigate whether the interstellar medium in these galaxies contains a central concentration above that expected from the exponential disk. ...

. The relation between ellipticity and size. Red data points are the observed data; most of them have elongated shapes, and larger galaxies tend to have larger ellipticities. Gray-colored regions represent the probability distributions calculated with the computer simulations, in which two galaxies are located at so close distance that they are blended as an elongated galaxy, as shown in the right pictures schematically.
