Dissecting the Main Sequence: AGN Activity and Bulge Growth in the Local
  Universe
  Local galaxies from the Sloan Digital Sky Survey are used to provide
additional support for an evolutionary pathway in which AGN activity is
associated with star-formation quenching. Composite, Seyfert 2 and LINER
galaxies account for $\sim$60\% of all star-formation in massive galaxies
($M_\star > 10^{10.5} M_\odot$). Inclusion of these galaxies results in a
"turnover" in the $SFR - M_\star$ relation for massive galaxies. Our analysis
shows that bulge growth has already occurred in the most massive galaxies
($M_\star > 10^{10.5}$ $M_\odot$), and bulges continue to grow as galaxies
quench and redden, $(g-r)$ = 0.5 $\rightarrow$ 0.75. Significant bulge growth
is also occurring in low mass starburst galaxies ($M_\star < 10^{10.5}
M_\odot$) at 0.5 dex above the "main sequence" (MS), where we find an increase
in $B/T$ from 0.1 $\rightarrow$ 0.3 and bluer colours, $(g-r) < 0.25$ compared
to low-mass galaxies on the MS.
