Abstract

It has been more than 40 years since magnetized radio filaments were first discovered toward the Galactic Center (GC), providing some of the earliest evidence of energetic activity in this region. Since then, a large population of synchrotron‑emitting filaments has been identified. In particular, the recent MeerKAT survey has become an invaluable resource for probing the extreme environment of the GC, increasing the known filament population by an order of magnitude. In this talk, I will discuss the statistical properties of the GC filaments, compare them with similar structures recently found in the intracluster medium (ICM), and examine whether the GC filaments trace past activity of Sgr A*.
