Early Stages of Ionization
VLA Survey
Weak and Compact Radio Emission in Early High-Mass Star Forming Regions.
Example of our VLA observations towards high-mass star forming regions with radio detections that have morphologies and other observational parameters that resemble collimated ionized jets (Rosero et al. 2016).
Massive Outflows
The Evolution of Outflows towards High-mass Stars
ALMA observations of molecular transitions to study ejection and accretion phenomena and use the kinematics to determine if the cm-wave detections are tracing a jet or a photoionized disk.
Example of our observations showing the molecular outflows (ALMA: blue and red) and the ionized jet (VLA: green) for three type of cores (Rosero et al. in prep).
