Scalar Emission in the Bulk in a Rotating Black Hole Background
S. Creek, O. Efthimiou, P. Kanti +1
We study the emission of scalars into the bulk from a higher-dimensional rotating black hole. We obtain an analytic solution to the field equation by employing matching techniques…
Pseudo-3-Branes in a Curved 6D Bulk
C. Bogdanos, A. Kehagias, K. Tamvakis
We consider a model involving a 4-brane in a 6D bulk which carries sigma model fields. An axion field on the 4-brane cancels the pressure along one direction leading to an effectiv…
Greybody factors in a rotating black-hole background-II : fermions and gauge bosons
S. Creek, O. Efthimiou, P. Kanti +1
We study the emission of fermion and gauge boson degrees of freedom on the brane by a rotating higher-dimensional black hole. Using matching techniques, for the near-horizon and fa…
Synergistic Gravity and the Role of Resonances in GRS-Inspired Braneworlds
C. Bogdanos, A. Dimitriadis, K. Tamvakis
We consider 5D braneworld models of quasi-localized gravity in which 4D gravity is reproduced at intermediate scales while the extra dimension opens up at both the very short and t…
Cosmic Acceleration Data and Bulk-Brane Energy Exchange
C. Bogdanos, S. Nesseris, L. Perivolaropoulos +1
We consider a braneworld model with bulk-brane energy exchange. This allows for crossing of the w=-1 phantom divide line without introducing phantom energy with quantum instabiliti…
Greybody Factors for Brane Scalar Fields in a Rotating Black-Hole Background
S. Creek, O. Efthimiou, P. Kanti +1
We study the evaporation of (4+n)-dimensional rotating black holes into scalar degrees of freedom on the brane. We calculate the corresponding absorption probabilities and cross-se…
