Title: ChaMPlane II: Optical spectra and IR imaging identification of ChaMPlane X-ray sources
Abstract: We propose to conduct Phase II of our Chandra Multiwavelength Plane (ChaMPlane) Survey to complete our study of the nature and distributions of low luminosity accretion sources in the Galaxy. Phase II is the optical spectroscopic and IR imaging follow-up of the ChaMPlane X-ray sources identified in Phase I under a NOAO long term survey project (2000 - 2005). We obtained 65 Mosaic fields (V,R,I,Ha) covering ~23 square degrees and 154 ACIS observations on 105 distinct Chandra fields. The optical spectroscopic follow-up for ChaMPlane object classification and IR imaging follow-up for severely reddened ChaMPlane fields are the final, crucial steps for completing the survey. We propose to use CTIO-4m-Hydra for spectroscopy on Chandra IDs as faint as R~21, and CTIO-4m-ISPI for J,H,K photometry of ChaMPlane sources in Bulge fields obscured by interstellar dust. We have successfully observed with both of these instruments over the past 3 years to begin Phase II and already obtained significant results. This proposal is to transform our annual effort into a three-year project, as required to complete the ChaMPlane Survey. The complete survey results, Phase I+II, will be available to the public via the NOAO archive and our ChaMPlane website - http://hea-www.harvard.edu/ChaMPlane
