A Short Scale Length for the α-Enhanced Thick Disk of the Milky Way: Evidence from Low-Latitude SEGUE Data
Judy Y. Cheng, Constance M. Rockosi, Heather L. Morrison +12
We examine the α-element abundance ratio, [α/Fe], of 5620 stars, observed by the Sloan Extension for Galactic Understanding and Exploration survey in the region 6 kpc < R < 16 kpc,…
Metallicity Gradients in the Milky Way Disk as Observed by the SEGUE Survey
Judy Y. Cheng, Constance M. Rockosi, Heather L. Morrison +6
The observed radial and vertical metallicity distribution of old stars in the Milky Way disk provides a powerful constraint on the chemical enrichment and dynamical history of the…

Nicole M. Putnam, Judy Y. Cheng, Elizabeth J. McGrath +2
We describe a three hour inquiry activity involving converging lenses and telescopes as part of a semester-long astronomy lab course for non-science majors at Hartnell Community Co…
Automated Morphological Classification of SDSS Red Sequence Galaxies
Judy Y. Cheng, S. M. Faber, Luc Simard +4
(abridged) In the last decade, the advent of enormous galaxy surveys has motivated the development of automated morphological classification schemes to deal with large data volumes…
