A Generalized Class of Taub-NUT-Scalar Metrics
Fataneh Bakherad, Behrouz Mirza, Reza Bahani +2
We consider a class of three-parameter metrics that was introduced in \cite{azizallahi2024three}. The class of metrics contain Zipoy-Voorhees (ZV) and Fisher-Janis-Newman- Winicour…
Accelerating FJNW Metric
Homayon Anjomshoa, Behrouz Mirza, Alireza Azizallahi
We derive exact form of accelerating Fisher-Janis-Newman-Winicour (FJNW) metric by a simple perturbative method. We also argue that by using Buchdahl transformations one can obtain…
A class of charged and charged-Taub-NUT metrics in the presence of a massless scalar field and some of their astrophysical aspects
Fatemeh Sadeghi, Behrouz Mirza, Marzieh Moradzadeh
We consider a class of exact solutions to the Einstein equations in the presence of a scalar field, recently introduced in [arXiv:2307.09328, arXiv:2307.13588], and derive their ge…
A class of charged-Taub-NUT-scalar metrics via Harison and Ehlers Transformations
Mahnaz Tavakoli Kachi, Behrouz Mirza, Fatemeh Sadeghi
We consider a class of axially symmetric solutions to Einstein's equations incorporating a -dependent scalar field and extend these solutions by introducing electric and magneti…
Modelling the Sgr A and M87 shadows by using the Kerr-Taub-NUT metrics in the presence of a scalar field
khadije Jafarzade, Masoumeh Ghasemi-Nodehi, Fatemeh Sadeghi +1
The recent unveiling of the images of Sgr A* and M87* has significantly advanced our understanding of gravitational physics. In this study, we derive a class of Kerr-Taub-NUT metri…
A class of Taub-NUT-scalar metrics via Ehlers transformations
Ali Derekeh, Behrouz Mirza, Pouya Heidari +2
We derive a class of Taub-NUT metrics in the presence of a scalar field (TNS) by using Ernst equations and potential, as well as using Ehlers transformations on the exact solutions…
Nonperturbative thermodynamic extrinsic curvature of the anyon gas
Mahnaz Tavakoli Kachi, Behrouz Mirza, Fatemeh Sadat Hashemi
Thermodynamic extrinsic curvature is a new mathematical tool in thermodynamic geometry. By using the thermodynamic extrinsic curvature, one may obtain a more complete geometric rep…
