Loop Quantum Cosmology and Boundary Proposals
Martin Bojowald, Kevin Vandersloot
For many years, the most active area of quantum cosmology has been the issue of choosing boundary conditions for the wave function of a universe. Recently, loop quantum cosmology,…
Constraints Algebra and Equations of Motion in Bohmian Interpretation of Quantum Gravity
Ali Shojai, Fatimah Shojai
It is shown that introducing the quantum effects using deBroglie--Bohm theory in the canonical formulation of gravity would change the constraints algebra. The new algebra is deriv…
Quantum suppression of the generic chaotic behavior close to cosmological singularities
Martin Bojowald, Ghanashyam Date
In classical general relativity, the generic approach to the initial singularity is very complicated as exemplified by the chaos of the Bianchi IX model which displays the generic…
Global existence problem in -Gowdy symmetric IIB superstring cosmology
Makoto Narita
We show global existence theorems for Gowdy symmetric spacetimes with type IIB stringy matter. The areal and constant mean curvature time coordinates are used. Before coming to tha…
LISA Capture Sources: Approximate Waveforms, Signal-to-Noise Ratios, and Parameter Estimation Accuracy
Leor Barack, Curt Cutler
Captures of stellar-mass compact objects (COs) by massive () black holes (MBHs) are potentially an important source for LISA, the proposed space-based gravitatio…
A physical template family for gravitational waves from precessing binaries of spinning compact objects: Application to single-spin binaries
Yi Pan, Alessandra Buonanno, Yanbei Chen +1
The detection of the gravitational waves (GWs) emitted by precessing binaries of spinning compact objects is complicated by the large number of parameters (such as the magnitudes a…
