Anderson et al. (2014) present parsec-scale
interferometric maps of HCN(1-0) and HCO+(1-0) emission from dense
gas in the star-forming region 30 Doradus, obtained using the Australia
Telescope Compact Array (ATCA). This extreme star-forming region, located in
the Large Magellanic Cloud (LMC), is characterized by a very intense
ultraviolet ionizing radiation field and sub-solar metallicity, both of which
are expected to impact molecular cloud structure. They detect 13 bright, dense
clumps within the 30 Doradus-10 giant molecular cloud. - The multi-wavelength
image shows Spitzer 8 micron (red), MCELS Halpha (green), Chandra X-rays (blue)
and MAGMA CO(1-0) contours (gray). Blue circles indicate the location of YSOs.
Magenta marks the locations of the H2O masers. YSO and maser
locations lie along a possible filamentary structure represented by the dashed
line. White contours represent the ATCA HCO+ integrated intensity
map.
