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…
A compact Keplerian-like disc and H30 emission towards the radio jet in the massive protostar W75N(B)-VLA3
A. Sanchez-Monge, J. F. Gomez, J. M. Torrelles +13
Studying young, high-mass stellar objects is challenging for testing models of massive star formation due to their great distances, often kiloparsecs away. This requires extremely…
Helical Magnetic Field in a Massive Protostellar Jet
A. Rodríguez-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…
An SiO Toroid and Wide-angle Outflow associated with the Massive Protostar W75N(B)-VLA2
Jose F. Gomez, Jose M. Torrelles, Josep M. Girart +12
We have carried out ALMA observations of the massive star-forming region W75N(B), which contains the massive protostars VLA1, VLA2, and VLA3. Particularly, VLA2 is an enigmatic pro…
AGN candidates in the VVV near-IR galaxy catalogue
Laura D. Baravalle, Eduardo O. Schmidt, M. Victoria Alonso +7
The goal of this work is to search for Active Galactic Nuclei (AGN) in the Galactic disc at very low latitudes with |b| 2. For this, we studied the five sources from th…
Zooming into the Collimation Zone in a Massive Protostellar Jet
Carlos Carrasco-González, Alberto Sanna, Adriana Rodríguez-Kamenetzky +5
Protostellar jets have a fundamental role at the earliest evolution of protostars of all masses. In the case of low-mass (<8 Msun) protostars, strong observational evidence exists…
Characterizing the radio continuum nature of sources in the massive star-forming region W75N (B)
A. Rodríguez-Kamenetzky, C. Carrasco-González, J. M. Torrelles +11
The massive star-forming region W75N~(B) is thought to host a cluster of massive protostars (VLA~1, VLA~2, and VLA~3) undergoing different evolutionary stages. In this work, we pre…
The Highly Collimated Radio Jet of HH 80-81: Structure and Non-Thermal Emission
Adriana Rodríguez-Kamenetzky, Carlos Carrasco-González, Anabella Araudo +7
Radio emission from protostellar jets is usually dominated by free-free emission from thermal electrons. However, in some cases, it has been proposed that non-thermal emission coul…
A comparison of the radio and optical time-evolution of HH~1 and 2
L. F. Rodriguez, A. C. Raga, A. Rodriguez-Kamenetzky +1
We present a comparison between the time-evolution over the past years of the radio continuum and H emission of HH~1 and 2. We find that the radio continuum and the H$…
An extremely high velocity molecular jet surrounded by an ionized cavity in the protostellar source Serpens SMM1
Charles L. H. Hull, Josep M. Girart, Lars E. Kristensen +6
We report ALMA observations of a one-sided, high-velocity (80 km s) CO() jet powered by the intermediate-mass protostellar source Serpens SMM1-a.…
Investigating Particle Acceleration in Protostellar Jets: The Triple Radio Continuum Source in Serpens
Adriana Rodríguez-Kamenetzky, Carlos Carrasco-González, Anabella Araudo +5
While most protostellar jets present free-free emission at radio wavelengths, synchrotron emission has been also proposed to be present in a handful of these objects. The presence…
