Star Formation at the Periphery of a Molecular Superbubble: The Case of G12.79+0.43
Arun Seshadri, Veena V. S., Sarita Vig +1
We present a multiwavelength investigation of the molecular cloud complex G12.79+0.43, which extends over on the sky. Several infrared- and radio-bright regions are arran…
Detection of non-thermal radio emission components from the Orion Nebula: stellar jets, cloud collision or feedback from stellar winds?
Md Rashid, Nirupam Roy, Prasun Dutta +5
The Orion Nebula is the closest high-mass star-forming region, making it an ideal laboratory to investigate physical processes in complex star-forming environments. At radio freque…
Particle Acceleration and Depolarization in the Protostellar jet knots HH 80 and HH 81
A. G. Cheriyan, S. Vig, Nirupam Roy +4
Linearly polarized emission is a powerful tracer of magnetic field geometry and particle acceleration in protostellar jets. We present a polarimetric study of the HH objects HH 80…
First detection of Circular Polarization in radio continuum towards a Massive Protostar
A. G. Cheriyan, S. Vig, Nirupam Roy +4
Polarization measurements provide strong constraints on magnetic fields in star-forming systems. While magnetic field estimates of a few kiloGauss (kG) have been obtained near the…
Helical Magnetic Field in a Massive Protostellar Jet
A. RodrÃguez-Kamenetzky, A. Pasetto, C. Carrasco-González +7
Highly collimated outflows (jets) are observed across a wide range of astrophysical systems involving the accretion of material onto central objects, from supermassive black holes…
