    • Dense gas in the Galactic central molecular zone is warm and heated by turbulence 

      Ginsburg, A.; Henkel, C.; Ao, Y.; Riquelme, D.; Kauffmann, J.; Pillai, T.; Mills, E.~A.~C.; Requena-Torres, M.~A.; Immer, K.; Testi, L.; Ott, J.; Bally, J.; Battersby, C.; Darling, J.; Aalto, S.; Stanke, T.; Kendrew, S.; Kruijssen, J.~M.~D.; Longmore, S.; Guesten, R.; Menten, K.~M.; Dale, James (2016-01-26)
      Context. The Galactic center is the closest region where we can study star formation under extreme physical conditions like those in high-redshift galaxies. Aims. We measure the temperature of the dense gas in the central ...

    • Direct measurements of carbon and sulfur isotope ratios in the Milky Way 

      Yan, Y. T.; Henkel, C.; Kobayashi, C.; Menten, K. M.; Gong, Y.; Zhang, J. S.; Yu, H. Z.; Yang, K.; Xie, J. J.; Wang, X.Y. (2023-02-14)
      With the IRAM 30-m telescope, we performed observations of the $J$ = 2-1 transitions of CS, C$^{33}$S, C$^{34}$S, C$^{36}$S, $^{13}$CS, $^{13}$C$^{33}$S, and $^{13}$C$^{34}$S as well as the $J$ = 3-2 transitions of C$^{33}$S, ...

(2016-01-14)
      We are performing a series of observations with ground-based telescopes toward Planck Galactic cold clumps (PGCCs) in the λ Orionis complex in order to systematically investigate the effects of stellar feedback. In the ...
