A Universal Smarr Formula via Coupling Constants
Kamal Hajian, Bayram Tekin, Onur Ucanok
In gravitational theories containing matter fields and higher-derivative corrections, the standard Smarr formula often fails unless all dimensionful couplings are incorporated cons…
Can Fractional Time Operators Reproduce Gravitational-Wave Memory? A No-Go Result
Sercan Kaya, Bayram Tekin
We initiate an investigation into whether fractional calculus, with its intrinsic long-tailed memory and nonlocal features, can provide a viable model for gravitational-wave memory…
Perturbative Analytical Construction of Bowen-York Initial Data for Binary Black Holes up to Third Order in Spin and Linear Momentum
Leyla Ogurol, Tore Boybeyi, Bayram Tekin
We analytically construct initial data for binary black hole systems by solving the Einstein constraint equations within the Bowen-York framework. Allowing for arbitrarily oriented…
Instability and Information Production Around Kerr Black Holes: Effects on Entropy and the Shadow
Aydin Tavlayan, Bayram Tekin
Massless or massive particles in unstable orbits around a Kerr black hole exhibit exponentially unstable motion when perturbed. They either plunge into the black hole or escape to…
Physical Interpretations of Integration Constants and Large Gauge Effects in Flat and AdS Spacetimes
Leyla Ogurol, Bayram Tekin
As in other partial differential equations, one ends up with some arbitrary constants or arbitrary functions when one integrates Einstein's equations, or more generally field equat…
Consistency Problems of Conformal Killing Gravity
Emel Altas, Bayram Tekin
We show that gravity field equations based on a tensor with rank greater than 2 have consistency problems in the sense that integration constants in the solutions, such as the para…
