We report the detection of 10 new X-ray filaments using the data from the Chandra X-ray satellite for the inner 60 ( 15 pc) around the Galactic center (GC). All these X-ray filaments are characterized by nonthermal energy spectra, and most of them have pointlike features at their heads that point inward. Fitted with the simple absorbed power-law model, the measured X-ray flux from an individual filament in the 2–10 keV band is 2:8 ; 10 14 to 10 13 ergs cm 2 s 1, and the absorption-corrected X-ray luminosity  is 1032–1033 ergs s 1 at a presumed distance of 8 kpc to the GC. 
We speculate the origin(s) of these filaments by morphologies and by comparing their X-ray images with the corresponding radio and infrared images. On the basis of the combined information available, we suspect that these X-ray filaments might be pulsar wind nebulae associated with pulsars of ages 103 to 3 ; 105 yr. The fact that most of the filament tails point outward may further suggest a high-velocity wind blowing away from the GC
