Refining the mass estimate for the intermediate-mass black hole candidate in NGC 3319
Benjamin L. Davis, Alister W. Graham
Recent X-ray observations by Jiang et al. have identified an active galactic nucleus (AGN) in the bulgeless spiral galaxy NGC 3319, located just Mpc away, and suggest…
Defining the (Black Hole)-Spheroid Connection with the Discovery of Morphology-Dependent Substructure in the -- and -- Diagrams: New Tests for Advanced Theories and Realistic Simulations
Nandini Sahu, Alister W. Graham, Benjamin L. Davis
For 123 local galaxies with directly-measured black hole masses (), we provide the host spheroid's Sérsic index (), effective half-light radius ($\rm R_{e,…
Revealing Hidden Substructures in the - Diagram, and Refining the Bend in the - Relation
Nandini Sahu, Alister W. Graham, Benjamin L. Davis
Using 145 early- and late-type galaxies (ETGs and LTGs) with directly-measured super-massive black hole masses, , we build upon our previous discoveries that: (i) LTGs, mos…
Investigating the Origins of Spiral Structure in Disk Galaxies through a Multiwavelength Study
Ryan Miller, Daniel Kennefick, Julia Kennefick +5
The density-wave theory of spiral structure proposes that star formation occurs in or near a spiral-shaped region of higher density that rotates rigidly within the galactic disk at…
Black Hole Mass Scaling Relations for Early-Type Galaxies: - and -
Nandini Sahu, Alister W. Graham, Benjamin L. Davis
Analyzing a sample of 84 early-type galaxies with directly-measured super-massive black hole masses---nearly doubling the sample size of such galaxies with multi-component decompos…
A Consistent Set of Empirical Scaling Relations for Spiral Galaxies: The - Relations
Benjamin L. Davis, Alister W. Graham, Françoise Combes
Using the latest sample of 48 spiral galaxies having a directly measured supermassive black hole mass, , we determine how the maximum disk rotational velocity, (a…
