The Barbero-Immirzi Parameter as a Scalar Field: K-Inflation from Loop Quantum Gravity?
Victor Taveras, Nicolas Yunes
We consider a loop-quantum gravity inspired modification of general relativity, where the Holst action is generalized by making the Barbero-Immirzi (BI) parameter a scalar field, w…
Chern-Simons Modified Gravity as a Torsion Theory and its Interaction with Fermions
Stephon Alexander, Nicolas Yunes
We study the tetrad formulation of Chern-Simons (CS) modified gravity, which adds a Pontryagin term to the Einstein-Hilbert action with a spacetime-dependent coupling field. We fir…
Perturbations of Schwarzschild Black Holes in Chern-Simons Modified Gravity
Nicolas Yunes, Carlos F. Sopuerta
We study perturbations of a Schwarzschild black hole in Chern-Simons modified gravity. We begin by showing that Birkhoff's theorem holds for a wide family of Chern-Simons coupling…
How do Black Holes Spin in Chern-Simons Modified Gravity?
Daniel Grumiller, Nicolas Yunes
No Kerr-like exact solution has yet been found in Chern-Simons modified gravity. Intrigued by this absence, we study stationary and axisymmetric metrics that could represent the ex…
Upper limits on gravitational wave emission from 78 radio pulsars
The LIGO Scientific Collaboration, B. Abbott, M. Kramer +1
We present upper limits on the gravitational wave emission from 78 radio pulsars based on data from the third and fourth science runs of the LIGO and GEO600 gravitational wave dete…
