LOFAR detections of low-frequency radio recombination lines towards Cassiopeia A
Ashish Asgekar, J. B. R. Oonk, S. Yatawatta +89
Cassiopeia A was observed using the Low-Band Antennas of the LOw Frequency ARray (LOFAR) with high spectral resolution. This allowed a search for radio recombination lines (RRLs) a…
An improved map of the Galactic Faraday sky
N. Oppermann, H. Junklewitz, G. Robbers +28
We aim to summarize the current state of knowledge regarding Galactic Faraday rotation in an all-sky map of the Galactic Faraday depth. For this we have assembled the most extensiv…
Faraday caustics: Singularities in the Faraday spectrum and their utility as probes of magnetic field properties
M. R. Bell, H. Junklewitz, T. A. Enßlin
We describe singularities in the distribution of polarized intensity as a function of Faraday depth (i.e. the Faraday spectrum) caused by line-of-sight (LOS) magnetic field reversa…
