Constraints on the Parameters of the Unseen Pulsar in the PWN G0.9+0.1   from Radio, X-Ray, and VHE Gamma-Ray Observations
  Radio, X-ray, and HESS gamma-ray observations of the Galactic Center (GC) composite supernova remnant SNR G0.9+0.1 are used to constrain a time-dependent injection model of the downstream electron spectrum responsible for the total multiwavelength spectrum. The effect of spindown power evolution aswell as nebular field evolution is employed to reproduce the present-day multiwavelength spectrum. Assuming a nebular magnetic field decay model of typical HESS-type pulsar wind nebulae (PWN), ending with a present-day field strength of 6muG, we obtain an initial spindown power of ~ 10E+38 ergs/s if we assume a birth period and age of 43ms and 6,500 yr respectively to reproduce the properties of the SNR shell. This gives a present-day spindown power of ~ 10E+37 ergs/s, which agrees well with the present-day spindown power derived from X-ray observations.
