TL;DR: In this paper, a color-magnitude diagram of more than 10,000 stars in the halo of the galaxy NGC 5128 (Centaurus A), based on WFPC2 images through V-band and I-band filters, is presented.
Journal ArticleDOI

Luisa Rebull,S. Guieu,John R. Stauffer,Lynne A. Hillenbrand,Alberto Noriega-Crespo,Karl Stapelfeldt,Sean Carey,John M. Carpenter,D. M. Cole,D. Padgett,S. E. Strom,S. C. Wolff +11 more
TL;DR: In this article, the authors presented observations of the North American and Pelican Nebulae region at 24, 70, and 160 μm with the Spitzer Space Telescope Multiband Imaging Photometer for Spitzer (MIPS) and used the MIPS data to identify 1286 young stellar object (YSO) candidates.
