Possible existence of wormholes in the central regions of halos

• Earlier we showed possible existence of wormholes in the outer regions of halo.
• We obtain here analogous results for the central parts of the galactic halo.
• Our result is an important compliment to the earlier result.
• This confirms possible existence of wormholes in most of the spiral galaxies.

An earlier study (Rahaman, et al., 2014 and Kuhfittig, 2014) has demonstrated the possible existence of wormholes in the outer regions of the galactic halo, based on the Navarro–Frenk–White (NFW) density profile. This paper uses the Universal Rotation Curve (URC) dark matter model to obtain analogous results for the central parts of the halo. This result is an important compliment to the earlier result, thereby confirming the possible existence of wormholes in most of the spiral galaxies.
