A note on wormholes in slightly modified gravitational theories
Peter K. F. Kuhfittig
Wormholes that meet the flare-out condition violate the weak energy condition in classical general relativity. The purpose of this note is to show that even a slight modification o…
Gravitational lensing of wormholes in the galactic halo region
Peter K. F. Kuhfittig
A recent study by Rahaman et al. has shown that the galactic halo possesses the necessary properties for supporting traversable wormholes, based on two observational results, the d…
Possible existence of wormholes in the galactic halo region
Farook Rahaman, P. K. F. Kuhfittig, Saibal Ray +1
Two observational results, the density profile from simulations performed in the CDM scenario and the observed flat galactic rotation curves, are taken as input with the aim of…
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…
Nonommutative wormholes in gravity
Mubasher Jamil, Farook Rahaman, Ratbay Myrzakulov +3
This paper discusses several new exact solutions of static wormholes in gravity with a noncommutative-geometry background, which replaces point-like structures by smeared ob…
Macroscopic wormholes in noncommutative geometry
Peter K. F. Kuhfittig
The purpose of this paper is to show that wormholes in noncommutative geometry can be macroscopic, based in part on an earlier study. The necessary violation of the weak energy con…
