The Dark Matter Halo Density Profile, Spiral Arm Morphology, and Supermassive Black Hole Mass of M33
Table 3
Spiral arm pitch angles, NFW concentration parameters, and central supermassive black hole mass for 5 galaxies. For the Malin 1 the spiral arm pitch angle is taken from Moore and Parker [65]. For M31, the pitch angle is the average of values taken from Arp [66] and Braun [67]. The NFW concentration value is taken from (1) Seigar [64], (2) Klypin et al. [68], (3) Seigar et al. [34], and (4) Seigar et al. [28]. The black hole mass estimates are taken from (5) Ghez et al. [69], (6) Bender et al. [54], and (7) Gebhardt et al. [18].
