1.28GHz filaments in the central molecular zone
Listed in IVOA Registry (Virtual Observatory)
We present a catalog of 1.28GHz radio filaments observed by MeerKAT over the innermost 200pc of the Galaxy (roughly +/-1:5), which includes the central molecular zone.
Description
The catalog is generated by repurposing software developed for the automated detection of filaments in solar coronal loops. There are two parts to the catalog.
The first part, the main catalog, provides a point-by-point listing of locations and basic observational properties along each detected filament. The second part is a summary catalog that provides a listing of mean, median, or total values of various properties for each filament. Tabulated quantities include position, length, curvature, brightness, and spectral index.

The catalogs contain a heterogeneous mix of filamentary structures, including nonthermal radio filaments, and parts of supernova remnants and thermally emitting regions (e.g., HII regions). We discuss criteria for selecting useful subsamples of filaments from the catalogs, and some of the details encountered in examining filaments or selections of filaments from the catalogs.
