Implications of Einstein-Maxwell dilaton-axion gravity from the black hole continuum spectrum
Indrani Banerjee, Bhaswati Mandal, Soumitra SenGupta
String inspired models can serve as potential candidates to replace GR in the high energy regime where quantum gravity is expected to play a vital role. Such models not only subsum…

Signatures of Einstein-Maxwell dilaton-axion gravity from the observed jet power and the radiative efficiency
Indrani Banerjee, Bhaswati Mandal, Soumitra SenGupta
The Einstein-Maxwell dilaton-axion (EMDA) gravity arises in the low energy effective action of the heterotic string theory and provides a simple framework to explore the signatures…

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…
