Title: CTIO REU/PIA Observations: Lyman-Alpha Blob Candidates and RR Lyrae Variables

Abstract: We request 8 nights on the CTIO 1.0-m as part of the upcoming 2012 CTIO REU/PIA program. The main focus of this proposal will be to provide direct, hands-on observational experience to 8 undergraduate students in observational techniques, astronomical data reduction, and multi-wavelength photometry. In order to expose the students to a variety of astronomical observations, we will observe RR Lyrae variable stars and Lyman Alpha Blob (LAB) candidates. The RR Lyrae variable star observations are in collaboration with the Bowling Green State University Variable Star Project (BGSUVSP). The variable stars will be observed in several colors to refine their calibration as distance indicators, determine extinction and place constraints on stellar models. LAB candidates were chosen from space-based UV data from Swift/UVOT of 50 fields of quasi-stellar objects (QSOs) in the redshift range 0.556<z<0.565. Observations in the near-UV and optical are needed to rule out any other sources of diffuse Lyman-alpha emission. Additionally, a small fraction of the time will be allocated to observe scientifically interesting targets of the students own choosing.
