On The Hydrosphere Stability of TESS Targets: Applications to 700 d, 256 b, and 203 b
Paul Bonney, Julia Kennefick
A main determinant of the habitability of exoplanets is the presence of stable liquid surface water. In an era of abundant possible targets, the potential to find a habitable world…
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…
The Halos and Environments of Nearby Galaxies (HERON) I: Imaging, Sample Characteristics, and Envelope Diameters
R. Michael Rich, Aleksandr Mosenkov, Henry Lee-Saunders +16
We use a dedicated 0.7-m telescope to image the halos of 119 galaxies in the Local Volume to mag/arcsec. The sample is primarily from the 2MASS Large Galaxy At…
Infrared Imaging of SDSS Quasars: Implications for the Quasar K correction
Julia Kennefick, Shelly Bursick
We have imaged 45 quasars from the Sloan Digital Sky Survey (SDSS) with redshifts 1.85 < z < 4.26 in JHKs with the KPNO SQIID imager. By combining these data with optical magnitude…
Discovery of a relationship between spiral arm morphology and supermassive black hole mass in disk galaxies
Marc S. Seigar, Daniel Kennefick, Julia Kennefick +1
We present a relationship between spiral arm pitch angle (a measure of the tightness of spiral structure) and the mass of supermassive black holes (BHs) in the nuclei of disk galax…
