Implications of axionic hair on shadow of M87*
Indrani Banerjee, Subhadip Sau, Soumitra SenGupta
Detection of axion field can unfold intriguing facets of our universe in several astrophysical and cosmological scenarios. In four dimensions, such a field owes its origin to the c…
Silhouette of M87*: A new window to peek into the world of hidden dimensions
Indrani Banerjee, Sumanta Chakraborty, Soumitra SenGupta
The recent observation of the shadow of the supermassive black hole M87*, located at the centre of the M87 galaxy, by the Event Horizon Telescope collaboration has opened up a new…
Does black hole continuum spectrum signal f(R) gravity in higher dimensions?
Indrani Banerjee, Bhaswati Mandal, Soumitra SenGupta
Extra dimensions, which led to the foundation and inception of string theory, provide an elegant approach to force-unification. With bulk curvature as high as the Planck scale, hig…
Decoding signatures of extra dimensions and estimating spin of quasars from the continuum spectrum
Indrani Banerjee, Sumanta Chakraborty, Soumitra SenGupta
Continuum spectrum emitted by the accretion disk around quasars hold a wealth of information regarding the strong gravitational field produced by the massive central object. Such s…
Constraining extra-spatial dimensions with observations of GW170817
Kabir Chakravarti, Sumanta Chakraborty, Khun Sang Phukon +2
We derive the modifications introduced by extra-spatial dimensions beyond the four dimensional spacetime on the macroscopic properties of neutron stars, which in turn affect the gr…
