Image Segmentation to Distinguish Between Overlapping Human Chromosomes
R. Lily Hu, Jeremy Karnowski, Ross Fadely +1
In medicine, visualizing chromosomes is important for medical diagnostics, drug development, and biomedical research. Unfortunately, chromosomes often overlap and it is necessary t…
A Search for RR Lyrae Stars in Segue 2 and Segue 3
Erin Boettcher, Beth Willman, Ross Fadely +9
We present an extensive search for RR Lyrae stars in and around the ultra-faint Milky Way companions Segue 2 and Segue 3. The former (M_V = -2.5, Belokurov et al. 2009) appears to…
Star-Galaxy Classification in Multi-Band Optical Imaging
Ross Fadely, David W. Hogg, Beth Willman
Ground-based optical surveys such as PanSTARRS, DES, and LSST, will produce large catalogs to limiting magnitudes of r > 24. Star-galaxy separation poses a major challenge to such…
Substructure in the lens HE 0435-1223
Ross Fadely, Charles R. Keeton
We investigate the properties of dark matter substructure in the gravitational lens HE 0435-1223 (z_l=0.455) via its effects on the positions and flux ratios of the quadruply-image…
Segue 3: An Old, Extremely Low luminosity Star Cluster in the Milky Way's Halo
Ross Fadely, Beth Willman, Marla Geha +6
We investigate the kinematic and photometric properties of the Segue 3 Milky Way companion using Keck/DEIMOS spectroscopy and Magellan/IMACS g and r-band imaging. Using maximum lik…
A New Microlensing Event in the Doubly-Imaged Quasar Q0957+561
Laura J. Hainline, Christopher W. Morgan, J. N. Beach +6
We present evidence for ultraviolet/optical microlensing in the gravitationally lensed quasar Q0957+561. We combine new measurements from our optical monitoring campaign at the Uni…
