Revisiting a family of wormholes: geometry, matter, scalar quasinormal modes and echoes
Poulami Dutta Roy, S. Aneesh, Sayan Kar
We revisit a family of ultra-static Lorentzian wormholes which includes Ellis-Bronnikov spacetime as a special case. We first show how the required total matter stress energy (whic…

Gravitational waves from quasinormal modes of a class of Lorentzian wormholes
S. Aneesh, Sukanta Bose, Sayan Kar
Quasinormal modes of a two-parameter family of Lorentzian wormhole spacetimes, which arise as solutions in a specific scalar-tensor theory associated with braneworld gravity, are o…
