Analysis of radial and quasiradial oscillations in quark stars for different equations of state

Nivamani Rajbongshi, Umananda Dev Goswami

We investigate quark stars (QSs) described by three quark matter (QM)equations of state (EoSs) and analyse their radial and quasiradial oscillation modes within the slowly rotating…

Lensing Signatures of a Primary Hair Black Hole Solution

Rahul Das, Umananda Dev Goswami

We investigate the weak and strong field gravitational lensing of light by a primary hair black hole (BH) solution obtained within the framework of the gravitational decoupling (GD…

Five-Dimensional Traversable Wormholes in Einstein-Gauss-Bonnet Gravity with a Cloud of Strings

Jaydeep Goswami, Umananda Dev Goswami

We present an exact static and spherically symmetric traversable wormhole solution in 5D Einstein-Gauss-Bonnet (EGB) gravity supported by a Letelier cloud of strings. The physicall…

Strong field lensing and shadows of gravity black holes

Rahul Das, Umananda Dev Goswami

We investigate the strong field lensing of light by black holes (BHs)emerging in theory of gravity, which is an extension of gravity theory by including…

Probing CDM-mimicking gravity model using gravitational waves from compact binary coalescences

Sikha Gogoi, Umananda Dev Goswami

The direct detection of gravitational waves (GWs) is a very significant achievement in the history of physics and has opened a new window to probe the possible deviations of physic…

Traversable wormholes in gravity: Energy conditions, stability and quasinormal modes

Jaydeep Goswami, Rupam Jyoti Borah, Umananda Dev Goswami

We investigate static and spherically symmetric traversable wormhole solutions in the framework of gravity by considering a power-law model of the form . By ad…
