2MASS wide field extinction maps: II. The Ophiuchus and the Lupus cloud complexe
Marco Lombardi, Charles J. Lada, Joao Alves
We present an extinction map of a ~1,700 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…
The Embedded Massive Star Forming Region RCW 38
Scott J. Wolk, Tyler L. Bourke, Miquela Vigil
RCW~38 is a uniquely young (1 Myr), embedded () stellar cluster surrounding a pair of early O stars (O5.5) and is one of the few regions within 2 kpc other th…
Near-infrared reddening of extra-galactic GMCs in a face-on geometry
Jouni Kainulainen, Mika Juvela, Joao Alves
[Abridged] We describe the near-infrared reddening signature of giant molecular clouds (GMCs) in external galaxies. In particular, we examine the E(J-H) and E(H-K) color-excesses,…
Hunting Galaxies to (and for) Extinction
Jonathan B. Foster, Carlos Román-Zúñiga, Alyssa A. Goodman +2
In studies of star-forming regions, near-infrared excess (NIRX) sources--objects with intrinsic colors redder than normal stars--constitute both signal (young stars) and noise (e.g…
The nature of the dense core population in the Pipe Nebula: A survey of NH3, CCS, and HC5N molecular line emission
J. M. Rathborne, C. J. Lada, A. A. Muench +2
Recent extinction studies of the Pipe Nebula (d=130 pc) reveal many cores spanning a range in mass from 0.2 to 20.4 Msun. These dense cores were identified via their high extinctio…
The Dynamical State of the Starless Dense Core FeSt 1-457: A Pulsating Globule?
E. D. Aguti, C. J. Lada, E. A. Bergin +2
High resolution molecular line observations of CS, HCO+, C18O and N2H+ were obtained toward the starless globule FeSt 1-457 in order to investigate its kinematics and chemistry. Th…
