  The non-thermal filament (NTF) radio structures clustered within a few
hundred parsecs of the Galactic Center (GC) are apparently unique to this
region of the Galaxy. Recent radio images of the GC using MeerKAT at 1 GHz have
revealed a multitude of faint, previously unknown NTF bundles (NTFBs), some of
which are comprised of as many as 10 or more individual filaments. In this work
we present Very Large Array (VLA) observations at C- and X-bands (4 - 12 GHz)
at arcsecond-scale resolutions of three of these newly-discovered NTFBs, all
located at southern Galactic latitudes. These observations allow us to compare
their total-intensity properties with those of the larger NTF population. We
find that these targets generally possess properties similar to what is
observed in the larger NTF population. However, the larger NTF population
generally has steeper spectral index values than what we observe for our chosen
targets. The results presented here based on the total-intensity properties of
these structures indicate that the NTFs are likely all formed from Cosmic Rays
(CRs). These CRs are either generated by a nearby compact source and then
diffuse along the NTF lengths or are generated by extended, magnetized
structures whose magnetic field undergoes reconnection with the NTF magnetic
field.
