JCMT BISTRO survey: Magnetic Fields within the Hub-Filament Structure in IC 5146
Jia-Wei Wang, Shih-Ping Lai, Chakali Eswaraiah +130
We present the 850 m polarization observations toward the IC5146 filamentary cloud taken using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) and its associated polar…
Constraining the nature of DG Tau A's thermal and non-thermal radio emission
S. J. D. Purser, R. E. Ainsworth, T. P. Ray +3
DG Tau A, a class-II young stellar object (YSO) displays both thermal, and non-thermal, radio emission associated with its bipolar jet. To investigate the nature of this emission,…
LOFAR MSSS: Flattening low-frequency radio continuum spectra of nearby galaxies
K. T. Chyży, W. Jurusik, J. Piotrowska +35
The shape of low-frequency radio continuum spectra of normal galaxies is not well understood, the key question being the role of physical processes such as thermal absorption in sh…
Interstellar magnetic cannon targeting the Galactic halo : A young bubble at the origin of the Ophiuchus and Lupus molecular complexes
J. -F. Robitaille, A. M. M. Scaife, E. Carretti +5
We report the detection of a new Galactic bubble at the interface between the halo and the Galactic disc. We suggest that the nearby Lupus complex and parts of the Ophiuchus comple…
Magnetic fields towards Ophiuchus-B derived from SCUBA-2 polarization measurements
Archana Soam, Kate Pattle, Derek Ward-Thompson +121
We present the results of dust emission polarization measurements of Ophiuchus-B (Oph-B) carried out using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) camera with its…
The First VLBI Detection of a Spiral DRAGN Core
Minnie Y. Mao, Jay M. Blanchard, Frazer Owen +8
The existence of spiral DRAGNs challenges standard galaxy formation theories. We present the first observation of 0313192, the archetypal spiral DRAGN, at VLBI resolutions. Spir…
A First Look at BISTRO Observations of The Oph-A core
Jungmi Kwon, Yasuo Doi, Motohide Tamura +119
We present 850 m imaging polarimetry data of the Oph-A core taken with the Submillimeter Common-User Bolometer Array-2 (SCUBA-2) and its polarimeter (POL-2), as part of our…
Investigation of the cosmic ray population and magnetic field strength in the halo of NGC 891
D. D. Mulcahy, A. Horneffer, R. Beck +24
Low-frequency radio continuum observations of edge-on galaxies are ideal to study cosmic-ray electrons (CREs) in halos via radio synchrotron emission and to measure magnetic field…
Exploring the making of a galactic wind in the star-bursting dwarf irregular galaxy IC 10 with LOFAR
V. Heesen, D. A. Rafferty, A. Horneffer +16
Low-mass galaxies are subject to strong galactic outflows, in which cosmic rays may play an important role, they can be best traced with low-frequency radio continuum observations,…
