ALMA Spatially Resolved Dense Molecular Gas Survey of Nearby Ultraluminous Infrared Galaxies
Imanishi, Masatoshi; Izumi, Takuma; Nakanishi, Kouichiro
We present the results of our Atacama Large Millimeter Array HCN J = 3-2 and HCO+ J = 3-2 line observations of a uniformly selected sample (>25) of nearby ultraluminous infrared galaxies (ULIRGs) at z < 0.15. The emission of these dense molecular gas tracers and continuum are spatially resolved in the majority of observed ULIRGs f…
Identifying Young Stellar Objects in the Outer Galaxy: l = 224° Region in Canis Major
Boyer, Martha L.; Szczerba, Ryszard; Elia, Davide +14 more
We study a very young star-forming region in the outer Galaxy that is the most concentrated source of outflows in the Spitzer Space Telescope GLIMPSE360 survey. This region, dubbed CMa-l224, is located in the Canis Major OB1 association. CMa-l224 is relatively faint in the mid-infrared, but it shines brightly at the far-infrared wavelengths as rev…
