چکیده
We explore the relation between dust and several fundamental properties of simulated galaxies using Dusty SAGE semi-analytic model. In addition to tracing standard galaxy properties, also tracks cold mass in interstellar medium (ISM), hot halo ejected by feedback activity. Based on their ISM content, we divide our into two categories: dust-poor dust-rich. split group subgroups: dust-rich (the latter contains that lack both halo). Halo have high outflow rates heated gas are more massive. based specific star formation rate (sSFR) star-forming quenched subgroups. At redshift z=0, find a relatively sSFR, low bulge-to-total (BTT) ratio, metallicity. The sSFR allows them produce stellar ejecta. Their metal-rich enables growth via grain accretion. opposite is seen group. Furthermore, typically late-types, while resemble early-type population, show how content evolves from being dust-poor. Finally, investigate production z=3 z=0 all groups evolve similarly, except for

The black hole mass – galaxy age relation
We present evidence that there is a significant correlation between the fraction of a galaxy’s mass that lies in its central black hole and the age of the galaxy’s stellar population. Since the absorption line indices that are used to estimate the age are luminosity weighted, they essentially measure the time since the last significant episode of star formation in the galaxy. The existence of t...
