Wormholes with low energy density
Peter K. F. Kuhfittig
In spite of their speculative nature, traversable wormholes are a topic of interest that started with the Einstein-Rosen bridge in 1935 and became a major research area with the in…
Possible formation of wormholes from dark matter in an isothermal galactic halo and void
Nayan Sarkar, Susmita Sarkar, Farook Rahaman +2
It is well known that traversable wormholes are valid solutions of the Einstein field equations, but these structures can only be maintained by violating the null energy condition.…
Compact stars: a generalized model
S. K. Maurya, Debabrata Deb, Saibal Ray +1
This paper discusses a generalized model for compact stars, assumed to be anisotropic in nature due to the spherical symmetry and high density. After embedding the four-dimensional…
Possible existence of wormholes in the central regions of halos
Farook Rahaman, P. Salucci, P. K. F. Kuhfittig +2
An earlier study [Rahaman et al. (2014) & Kuhfittig (2014)] has demonstrated the possible existence of wormholes in the outer regions of the galactic halo, based on the Navarro-Fre…
Noncommutative geometry inspired wormholes with conformal motion
Farook Rahaman, Saibal Ray, G. S. Khadekar +2
This paper discusses a new wormhole solution that admits conformal motion, given a noncommutative-geometry background. After a discussion of the wormhole geometry and the energy co…
