Description
The LOw-Frequency ARray (LOFAR) offers an unprecedented opportunity to study the magneto-ionised medium of the Milky Way. In this talk, I will present two mosaics constructed from the second data release of the LOFAR Two-Metre Sky Survey (LoTSS-DR2), which trace polarised synchrotron emission in the high-latitude inner and outer Galaxy. We associate the dominant observed structures with Loop III and the Local Bubble, providing new insight into the local interstellar environment.
We estimate the minimum distance to the Faraday structures associated with the Local Bubble to be 40–80 pc. The observed Faraday depth gradient suggests a connection to the curvature of the Local Bubble boundary. By comparing our results with existing models, we propose that, in addition to the shell, we may also be detecting contributions from the complex of local interstellar clouds (CLIC) residing within the cavity.
