Central X-ray point-sources found to be abundant in low-mass, late-type galaxies predicted to contain an intermediate-mass black hole
Alister W. Graham, Roberto Soria, Benjamin L. Davis +5
Building upon three late-type galaxies in the Virgo cluster with both a predicted black hole mass of less than 10 M and a centrally-located X-ray point-source,…
Potential Black Hole Seeding of the Spiral Galaxy NGC 4424 via an Infalling Star Cluster
Alister W. Graham, Roberto Soria, Bogdan C. Ciambur +2
Galaxies can grow through their mutual gravitational attraction and subsequent union. While orbiting a regular high-surface-brightness galaxy, the body of a low-mass galaxy can be…
Strong Evidence for the Density-wave Theory of Spiral Structure in Disk Galaxies
Hamed Pour-Imani, Daniel Kennefick, Julia Kennefick +3
The density-wave theory of galactic spiral-arm structure makes a striking prediction that the pitch angle of spiral arms should vary with the wavelength of the galaxy's image. The…
The local black hole mass function derived from the M_{BH}-P and the M_{BH}-n relations
Burcin Mutlu Pakdil, Marc S. Seigar, Benjamin L. Davis
We present a determination of the supermassive black hole (SMBH) mass function for early- and late-type galaxies in the nearby universe (z<0.0057), established from a volume-limite…
Constraining dark matter halo profiles and galaxy formation models using spiral arm morphology. II. Dark and stellar mass concentrations for 13 nearby face-on galaxies
Marc S. Seigar, Benjamin L. Davis, Joel Berrier +1
We investigate the use of spiral arm pitch angles as a probe of disk galaxy mass profiles. We confirm our previous result that spiral arm pitch angles (P) are well correlated with…
