THE ASTROPHYSICAL GRAVITATIONAL WAVE BACKGROUND: IMPACTS OF PRIMARY AND SECONDARY ANISOTROPIES ON THE GW-LSS CROSS-CORRELATION
… of GWs of either astrophysical (Astrophysical Gravitational Wave Background-AGWB) or cosmological origin create a Stochastic Gravitational Wave Background (SGWB). In this work we focus on AGWB energy density anisotropies. Major contribution to such anisotropies come come from the inhomogeneous …

Gravitational Waves in String Cosmology
We study the production of cosmological backgrounds of gravitational waves in string theory models of the early universe. After a discussion of stochastic gravitational wave backgrounds, we describe the Cosmic Gravitational Wave Background (CGWB), its sensitivity to ultra-violet physics, and …

From Black Holes to the Big Bang: Astrophysics and Cosmology with Gravitational Waves and their Electromagnetic Counterparts
The growing catalog of gravitational-wave signals from compact object mergers has allowed us to study the properties of black holes and neutron stars more precisely than ever before and has opened a new window through which to probe the earliest moments in our universe’s history. Population-level …

LIGO interferometer operating at design sensitivity with application to gravitational radiometry
… interferometers of the Laser Interferometer Gravitational Wave Observatory (LIGO) were built and commissioned. In fall 2005 design sensitivity was achieved, corresponding to a strain sensitivity of 2.5 x 10-23 Hz-1/2 at 150 Hz. All three interferometers are now in an extended science run. One …

Searching for stochastic gravitational waves using co-located interferometric detectors
… co-location, the two LIGO (Laser Interferometer Gravitational Wave Observatory) Hanford interferometers have not been used in the search for the stochastic gravitational wave background due to their coupling to a shared environment, which may be comparable to or exceed any gravitational signal. …

Exploring Non-Minimality in New Physics Beyond the Standard Model
… unique, identifiable signals at near future gravitational wave observatories sensitive to sub-Hz frequencies. We show that studying the gravitational wave background generated by the mergers of such objects may not only provide an indication of their existence but offer a unique opportunity …

Gravitational waves as direct probes of binary evolution and astrophysical environments
The field of gravitational-wave astronomy began with the detection of a merging heavy stellar-mass black-hole binary. Many such compact binaries have been detected since then and more massive black-hole mergers are expected to be detected as the rest of the gravitational-wave spectrum is opened up …
