Powerful H$_2$ Line-cooling in Stephan's Quintet : I - Mapping the Significant Cooling Pathways in Group-wide Shocks,
intergalactic medium shock waves
2014/12/22
We present results from the mid-infrared spectral mapping of Stephan's Quintet using the Spitzer Space Telescope. A 1000 km/s collision has produced a group-wide shock and for the first time the large...
Evidence for Multiple Pathways to Deuterium Enhancements in Protoplanetary Disks
Evidence Multiple Pathways Deuterium Enhancements Protoplanetary Disks
2012/2/23
The distributions of deuterated molecules in protoplanetary disks are expected to depend on the molecular formation pathways. We use observations of spatially resolved DCN emission from the disk aroun...
