Generalized Vaidya Spacetime in Cotton and Conformal Killing Theories
Metin Gürses, Yaghoub Heydarzade, Çetin Şentürk
We demonstrate that the non-vacuum field equations of Cotton gravity and Conformal Killing gravity admit a generalized class of Vaidya-type solutions. In particular, beyond the sta…
Generalized Misner-Sharp energy in gravity
Amin Rezaei Akbarieh, Navid Safarzadeh Ilkhchi, Yaghoub Heydarzade
In this work, we explore the formulation of the Misner-Sharp energy within the framework of gravity, a modified theory incorporating the Ricci scalar and th…
Cosmological Singularities in Brane Gravity
R. Jalalzadeh, S. Jalalzadeh, Y. Heydarzade
We present a comprehensive study of cosmological singularities within the framework of Covariant Extrinsic Gravity (CEG), addressing both the initial Big Bang singularity and poten…
Dynamical Wormhole Solutions in Gravity
Yaghoub Heydarzade, Maryam Ranjbar
A class of theories extends the Einstein-Hilbert action by incorporating a general function of and , the Ricci scalar and the trace of the ordinary energy-momentum…
