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 ... -
The dynamical evolution of molecular clouds near the Galactic Centre - I. Orbital structure and evolutionary timeline
Kruijssen, J.~M.~D.; Dale, James; Longmore, S.~N. (2015-02-21)We recently proposed that the star-forming potential of dense molecular clouds in the Central Molecular Zone (CMZ, i.e. the central few 100 pc) of the Milky Way is intimately linked to their orbital dynamics, potentially ... -
Molecular gas kinematics within the central 250 pc of the Milky Way
Henshaw, J.~D.; Longmore, S.~N.; Kruijssen, J.~M.~D.; Davies, B.; Bally, J.; Barnes, A.; Battersby, C.; Cunningham, M.~R.; Ginsburg, A.; Immer, K.; Jones, P.~A.; Kendrew, S.; Mills, E.~A.~C.; Molinari, S.; Moore, T.~J.~T.; Ott, J.; Pillai, T.; Rathborne, J.; Schilke, P.; Schmiedeke, A.; Testi, L.; Walker, D.; Walsh, A.; Zhang, Q.; Dale, James (2016-02-12)Using spectral line observations of HNCO, N2H+, and HNC, we investigate the kinematics of dense gas in the central ∼250 pc of the Galaxy. We present SCOUSE (Semi-automated multi-COmponent Universal Spectral-line fitting ... -
Protoplanetary disc evolution affected by star-disc interactions in young stellar clusters
Rosotti, G.~P.; de Juan Ovelar, M.; Hubber, D.~A.; Kruijssen, J.~M.~D.; Ercolano, B.; Walch, S.; Dale, James (2014-07-01)Most stars form in a clustered environment. Therefore, it is important to assess how this environment influences the evolution of protoplanetary discs around young stars. In turn, this affects their ability to produce ... -
Toward gas exhaustion in the W51 high-mass protoclusters
Ginsburg, A.; Goss, W.~M.; Goddi, C.; Galván-Madrid, R.; Dale, James; Bally, J.; Battersby, C.~D.; Youngblood, A.; Sankrit, R.; Darling, J.; Kruijssen, J.~M.~D.; Liu, H.~B.; Smith, R (2016-10-25)We present new JVLA observations of the high-mass cluster-forming region W51A from 2 to 16 GHz with resolution θfwhm ≈ 0.3−0.5″. The data reveal a wealth of observational results: (1) Currently forming, very massive (proto-O) ...
