A Hunt for Massive Starless Cores
Shuo Kong, Jonathan C. Tan, Paola Caselli +3
We carry out an ALMA (3-2) and 1.3~mm continuum survey towards 32 high mass surface density regions in seven Infrared Dark Clouds with the aim of finding massive starle…
Kiloparsec-Scale Simulations of Star Formation in Disk Galaxies III. Structure and Dynamics of Filaments and Clumps in Giant Molecular Clouds
Michael J. Butler, Jonathan C. Tan, Sven Van Loo
We present hydrodynamic simulations of self-gravitating dense gas in a galactic disk, exploring scales ranging from 1 kpc down to ~pc. Our primary goal is to understand h…
The Darkest Shadows: Deep Mid-Infrared Extinction Mapping of a Massive Protocluster
Michael J. Butler, Jonathan C. Tan, Jouni Kainulainen
We use deep Spitzer-IRAC imaging of a massive Infrared Dark Cloud (IRDC) G028.37+00.07 to construct a Mid-Infrared (MIR) extinction map that probes mass surface densities u…
Mid-Infrared Extinction Mapping of Infrared Dark Clouds II. The Structure of Massive Starless Cores and Clumps
Michael J. Butler, Jonathan C. Tan
(abridged) We develop the mid-infrared extinction (MIREX) mapping technique of Butler & Tan (2009, Paper I), presenting a new method to correct for the Galactic foreground emission…
Deuteration as an evolutionary tracer in massive-star formation
F. Fontani, Aina Palau, P. Caselli +7
Theory predicts, and observations confirm, that the column density ratio of a molecule containing D to its counterpart containing H can be used as an evolutionary tracer in the low…
Parsec-scale SiO Emission in an Infrared Dark Cloud
I. Jimenez-Serra, P. Caselli, J. C. Tan +4
We present high-sensitivity 2'x4' maps of the J=2-1 rotational lines of SiO, CO, 13CO and C18O, observed toward the filamentary Infrared Dark Cloud (IRDC) G035.39-00.33. Single-poi…
