We present observations of the Cygnus OB2 region obtained with the Giant Metrewave Radio Telescope (GMRT) at the frequencies of 325 MHz and 610 MHz. In this contribution we focus o…
G5.89: An Explosive Outflow Powered by a Proto-Stellar Merger?
Luis A. Zapata, Paul T. P. Ho, Estrella Guzman-Ccolque +6
The explosive outflows are a newly-discovered family of molecular outflows associated with high-mass star forming regions. Such energetic events are possibly powered by the release…
An Asymmetric Keplerian Disk Surrounding the O-type Protostar IRAS165474247

Episodic molecular outflow in the very young protostellar cluster Serpens South
Adele L. Plunkett, Hector G. Arce, Diego Mardones +5
The loss of mass from protostars, in the form of a jet or outflow, is a necessary counterpart to protostellar mass accretion. Outflow ejection events probably vary in their velocit…
