HCN/HNC intensity ratio: a new chemical thermometer for the molecular ISM
A. Hacar, A. D. Bosman, E. F. van Dishoeck
Context. The gas kinetic temperature (TK) determines the physical and chemical evolution of the Interestellar Medium (ISM). However, obtaining reliable TK estimates usually require…
A solution to the proplyd lifetime problem
Andrew J. Winter, Cathie J. Clarke, Giovanni P. Rosotti +2
Protoplanetary discs (PPDs) in the Orion Nebula Cluster (ONC) are irradiated by UV fields from the massive star C. This drives thermal winds, inducing mass loss rates of up to…
Disk masses in the Orion Molecular Cloud-2: distinguishing time and environment
Sierk. E. van Terwisga, Alvaro Hacar, Ewine F. van Dishoeck
The mass evolution of protoplanetary disks is driven by both internal processes and external factors, such as photoevaporation. Disentangling these two effects, however, has remain…
The warm and dense Galaxy - tracing the formation of dense cloud structures out to the Galactic Center
Thomas Stanke, Henrik Beuther, Jens Kauffmann +11
The past two decades have seen extensive surveys of the far-infrared to submillimeter continuum emission in the plane of our Galaxy. We line out prospects for the coming decade for…
Does radiative feedback make faint z>6 galaxies look small?
Sylvia Ploeckinger, Joop Schaye, Alvaro Hacar +3
Recent observations of lensed sources have shown that the faintest () galaxies observed at z=6-8 appear to be extremely compact. Some of…
