L.; Liu, Daizhong; Matsushita, Satoki; Shi, Yong; Imanishi, Masatoshi; Rawlings, Mark G.; Zhu, Ming; Eden, David; Davis, Timothy A.; Li, Xiaohu (2020-03-24)
      To study the high-transition dense-gas tracers and their relationships to the star formation of the inner $\sim$ 2 kpc circumnuclear region of NGC253, we present HCN $J=4-3$ and HCO$^+ J=4-3$ maps obtained with the James ...

R.; Oteo, I.; Scholtz, J.; Sawicki, M.; Smith, D. (2019-11-20)
      We identify multi-wavelength counterparts to 1,147 submillimeter sources from the S2COSMOS SCUBA-2 survey of the COSMOS field by employing a recently developed radio$+$machine-learning method trained on a large sample of ...
