Gas Disks and Supermassive Black Holes in Nearby Radio Galaxies

NGC 7052 (UGC 11718) This elliptical galaxy has a nuclear dust disk (b/a =
0.30). It has a twin-jet radio morphology on VLBA scales and a core-jet morphology
on VLA scales. The STIS slits were aligned parallel to the galaxy major axis. The
central kinematic and flux properties are listed in Table 3.23; the gas exhibits a regular
rotation profile. The fit to the central spectrum is not significantly improved by the
addition of a broad component. Data for this galaxy are shown in Figure 3.20 (see
key in Figure 3.1 for an explanation of these plots).
UGC 12064 This S0 galaxy has a nuclear dust disk (b/a = 0.54). It has a twin-jet
radio morphology on VLA scales. The STIS slits were aligned parallel to the dust
disk major axis. The central kinematic and flux properties are listed in Table 3.24;
the gas exhibits a regular rotation profile. The fit to the central spectrum is improved
by the addition of a broad component. Data for this galaxy are shown in Figure 3.21
(see key in Figure 3.1 for an explanation of these plots).
NGC 7626 (UGC 12531) This elliptical peculiar galaxy has a nuclear dust lane
(width : length = 0.17). It has a core-jet radio morphology on VLBA scales and
a twin-jet morphology on VLA scales. The STIS slits were aligned parallel to the
galaxy major axis. The central kinematic and flux properties are listed in Table 3.25;
