Faster rate of Hawking radiation in modified gravity constraining dark matter
Panchajanya Dey, Banibrata Mukhopadhyay
The exact theory of gravity in the strong field regime is still under debate. There are observations implying the need for modification to Einstein's gravity. On the other hand, th…
