Multi-probe analysis of strong-field effects in gravity
Mohsen Khodadi, Behnam Pourhassan, Emmanuel N. Saridakis
Covariant gravity is a viable extension of General Relativity, however its strong-field predictions remain largely untested. Using the static, spherically symmetric black-ho…
Can quantum gravity be both consistent and complete?
Mir Faizal, Lawrence M. Krauss, Arshid Shabir +2
General relativity, despite its profound successes, fails as a complete theory due to presence of singularities. While it is widely believed that quantum gravity has the potential…
Warm Inflation in gravity
Tuhina Ghorui, Prabir Rudra, Farook Rahaman +1
We investigate warm inflation in the framework of gravity within a Friedmann-Robertson-Walker spacetime. Unlike cold inflation, where the inflaton evolves in isolation, warm…

Salvatore Capozziello, Mir Faizal, Mir Hameeda +2
Effects from nonstandard corrections to Newtonian gravity, at large scale, can be investigated using the cosmological structure formation. In particular, it is possible to show if…
