2MASS wide field extinction maps. II. The Ophiuchus and the Lupus cloud complexes.

LOMBARDI M., LADA C.J. and ALVES J.

Abstract (from CDS):

We present an extinction map of a ∼1700 deg sq region that encloses the Ophiuchus, the Lupus, and the Pipe dark complexes using 42 million stars from the Two Micron All Sky Survey (2MASS) point source catalog. The use of a robust and optimal near-infrared method to map dust column density (nicer, described in Lombardi & Alves, 2001A&A...377.1023L) allow us to detect extinction as low as AK=0.05mag with a 2-σ significance, and still to have a resolution of 3arcmin on our map. We also present a novel, statistically sound method to characterize the small-scale inhomogeneities in molecular clouds. Finally, we investigate the cloud structure function, and show that significant deviations from the results predicted by turbulent models are observed.
