Cosmological Black hole Candidates: A Detailed Analysis of McVittie, Culetu, Sultana-Dyer, and Glass-Mashhoon Spacetimes
M. Esfandiar, F. Shojai, O. Zamani Jamshidi +1
This paper investigates the existence of cosmological black holes by analyzing the properties of trapping horizons in detail, based on Hayward's formalism of future outer and past…
Gravitational Collapse: Generalizing Oppenheimer-Snyder and a Conjecture on Horizon Formation Time
H. Khodabakhshi, H. Lu, F. Shojai
We generalize the Oppenheimer-Snyder model of gravitational collapse by considering a broader class of static, spherically symmetric exterior spacetimes, with an interior geometry…
Gravitational Landscapes: black holes with linear equations of state in asymptotically safe gravity
Ramin Hassannejad, Fatimah Shojai, Kazuharu Bamba
We study black holes with linear equation of state within the framework of asymptotically safe gravity. This study extends previous work on gravitational collapse in asymptotically…
Gravitational Collapse in Scale-Dependent Gravity
Ramin Hassannejad, Gaetano Lambiase, Fabio Scardigli +1
In this paper we study an Oppenheimer-Snyder (OS)-like gravitational collapse in the general framework of scale-dependent gravity. We explore the collapse in spherically symmetric…
Weak Energy Condition, Trapped Surfaces and Black hole Third Law
F. Bahmani, F. Shojai, Sh. Anjomshoaa
We consider the third law of thermodynamics for families of 4- and n-dimensional Vaidya black holes, including many of interest. Since there are several versions of the definition…
Generalized Oppenheimer-Snyder Gravitational Collapse into Regular Black holes
F. Shojai, A. Sadeghi, R. Hassannejad
We shall study the formation of a particular class of regular black holes from the gravitational collapse of a massive star. The inside geometry is described by spatially flat Frie…
