Millimeter and far-IR study of the IRDC SDC341.232-0.268
We analyze the molecular gas and dust associated with the infrared dark cloud SDC341.232-0.268 in order to investigate the characteristics and parameters of the gas, determine the evolutionary status of four embedded EGO candidates, and es- tablish possible infall or outflow gas motions. We base our...

| description |
We analyze the molecular gas and dust associated with the infrared dark cloud SDC341.232-0.268 in order to investigate the characteristics and parameters of the gas, determine the evolutionary status of four embedded EGO candidates, and es- tablish possible infall or outflow gas motions. We base our study on <sup>12</sup>CO(2-1), <sup>13</sup>CO(2-1), and C<sup>18</sup>O(2-1) data obtained with the APEX telescope, molecular data of high density tracers from the MALT90 survey and IR images from Spitzer, Herschel and ATLASGAL. The study reveals two clumps at −44 km s<sup>−1</sup> towards the IRDC, with densities of > 10<sup>4</sup>cm<sup>−3</sup>, typical of IRDCs, while high density tracers show H<sub>2</sub> densities > 10<sup>5</sup>. FIR images reveals the presence of cold dust linked to the molecular clumps and EGOs. A comparison of the spectra of the optically thin and optically thick molecular lines towards the EGOs suggests the existence of infall and outflow motions. |
