S. J. D. Purser, S. L. Lumsden, M. G. Hoare, S. Kurtz

TL;DR
This study presents the largest high-resolution radio survey of jets from massive protostars, revealing scaling relations with luminosity, jet-driving mechanisms, and evolutionary trends in star-forming cores.
Contribution
It provides new high-resolution radio observations of massive protostar jets, demonstrating their similarity to low-mass jets and analyzing their physical properties and evolution.
Findings
Radio luminosity scales with bolometric luminosity.
Jet mass loss rate correlates with luminosity as L_bol^0.9.
Jets can drive observed molecular outflows.
Abstract
In conjunction with a previous southern-hemisphere work, we present the largest radio survey of jets from massive protostars to date with high-resolution, () VLA observations towards two subsamples of massive star-forming regions of different evolutionary statuses: 48 infrared-bright, massive YSOs and 8 IRDCs containing 16 luminous () cores. For of the MYSO sample we detect thermal radio ( whereby ) sources coincident with the protostar, of which (13 jets and 25 candidates) are jet-like. Radio luminosity is found to scale with similarly to the low-mass case supporting a common mechanism for jet production across all masses. Associated radio lobes tracing shocks are seen towards of jet-like objects and are preferentially detected towards jets of…
