Non-stationary Energy of Perfect Fluid Sources in General Relativity
Emel Altas, Bayram Tekin
The ADM energy for asymptotically flat spacetimes or its generalizations to asymptotically non-flat spacetimes measure the energy content of a stationary spacetime, such as a singl…
Kerr-Vaidya type radiating black holes in semi-classical gravity with conformal anomaly
Metin Gurses, Bayram Tekin
Static black holes in the conformal anomaly-sourced semi-classical General Relativity in four dimensions were extended to rotating, stationary solutions, recently. These quantum-co…
A search for Planet Nine with small spacecraft:Three-body, post-Newtonian, non-gravitational, planetary and Kuiper Belt effects
Sahin Ulas Koprucu, Bayram Tekin
A hypothetical gravitating body in the outer Solar System, the so-called Planet Nine, was proposed to explain the unexpected clustering of the Kuiper Belt Objects. As it has not be…
Coupling Constants as Conserved Charges in Black Hole Thermodynamics
Kamal Hajian, Bayram Tekin
In a generic theory of gravity coupled to matter fields, the Smarr formula for black holes does not work properly if the contributions of the coupling constants defining the theory…
Partition Function of a Volume of Space in a Higher Curvature Theory
Aydin Tavlayan, Bayram Tekin
Recently, [Phys. Rev. Lett. 130, 221501 (2023)] Jacobson and Visser calculated the quantum partition function of a fixed, finite volume of a region with the topology of a ball in t…
A Tribute to S. Deser: Conserved Quantities in Generic Gravity Theories
Bayram Tekin
I describe parts of my joint work with S. Deser [March 19, 1931 - April 21, 2023] which started when I was working as a post-doc at Brandeis University in 2001. Our work was mostly…
