Probing the Low-mass End of the Black Hole Mass Function via a Study of Faint Local Spiral Galaxies
Michael S. Fusco, Benjamin L. Davis, Julia Kennefick +2
We present an analysis of the pitch angle distribution function (PADF) for nearby galaxies and its resulting black hole mass function (BHMF) via the well-known relationship between…
Evidence in favour of density wave theory through star formation history maps and spatially resolved stellar clusters
Shameer Abdeen, Daniel Kennefick, Julia Kennefick +7
Stationary Density Wave Theory predicts the existence of an age gradient across the spiral arms with a phase crossing at the co-rotation radius. Using star formation history (SFH)…
Determining the Co-Rotation Radii of Spiral Galaxies Using Spiral Arm Pitch Angle Measurements at Multiple Wavelengths
Shameer Abdeen, Daniel Kennefick, Julia Kennefick +4
The spiral arms spanning disk galaxies are believed to be created by density waves that propagate through galactic disks. We present a novel method of finding the co-rotation radiu…
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…
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…
Spirality: A Novel Way to Measure Spiral Arm Pitch Angle
Douglas W. Shields, Benjamin Boe, Casey Pfountz +6
We present the MATLAB code Spirality, a novel method for measuring spiral arm pitch angles by fitting galaxy images to spiral templates of known pitch. Computation time is typicall…
