Non-thermal emitters in Orion A

Abstract

cOrion A is the nearest star-forming complex containing a broad range of environments populated by protostars and Young Stellar Objects (YSOs) with different masses and evolutionary stages, representing a testbed for star formation theories. The VLA Orion A Large Survey (VOLS, PI: G. Busquet; see https://vols.fqa.ub.edu) large project has been granted with 306 hours of observing time with the Karl G. Jansky Very Large Array to perform the deepest survey at subarcsecond resolution of the Orion A molecular cloud. VOLS will observe at two frequency bands (8-12 GHz or 6 cm and 12-18 GHz or 2 cm) the northern part of the Orion A molecular cloud covering an area of ~0.5 deg2. The aim of the Master Thesis is identify non-thermal emitters in the VOLS field of view and investigate the origin of this emission. Non-thermal emission is characterised by a negative spectral index and it can be associated to shocked spots in the radio jets or stellar winds due to synchrotron emission or to very active magnetospheres in Class II/Class III YSOs.
