Gravitational Radiation Sources and Signatures

چکیده

The goal of these lecture notes is to introduce the developing research area of gravitational-wave phenomenology. In more concrete terms, they are meant to provide an overview of gravitational-wave sources and an introduction to the interpretation of real gravitational wave detector data. They are, of course, limited in both regards. Either topic could be the subject of one or more books, and certainly more than the few lectures possible in a summer school. Nevertheless, it is possible to talk about the problems of data analysis and give something of their avor, and do the same for gravitational wave sources that might be observed in the upcoming generation of sensitive detectors. These notes are an attempt to do just that. Despite an 83 year history, our best theory explaining the workings of gravity | Einstein's theory of general relativity | is relatively untested compared to other physical theories. This owes principally to the fundamental weakness of the gravitational force: the precision measurements required to test the theory were not possible when Einstein rst described it, or for many years thereafter. The direct detection of gravitational-waves is a central component of our rst investigations into the dynamics of the weakest of the known fundamental forces: gravity. It is only in the last 35 years that general relativity has been put to signi cant test. Today, the rst e ects of static relativistic gravity beyond those described by Newton have been well-studied using precision measurements of the motion of the planets, their satellites and the principal asteroids.

Gravitational Waves from a Cosmological Distribution of Sources

The advent of gravitational wave detectors such as the Laser Interferometer Space Antenna and the Advanced-Laser Interferometer Gravitational wave Observatory will make it possible to observe many gravitational wave emission phenomena that may or may not have electromagnetic counterparts. In many cases, gravitational waves serve as probes of length and time scales that range many orders of magn...

Gravitational Wave Sources from New Physics

Forthcoming advances in direct gravitational wave detection from kilohertz to nanohertz frequencies have unique capabilities to detect signatures from or set meaningful constraints on a wide range of new cosmological phenomena and new fundamental physics. A brief survey is presented of the post-inflationary gravitational radiation backgrounds predicted in cosmologies that include intense new cl...

Cosmic String Loops and Gravitational Radiation

Understanding of the signatures of cosmic string networks is limited by a large uncertainty in the sizes at which cosmic string loops form. We review cosmic string network evolution, and the gravitational signatures, with emphasis on this uncertainty. We then review a recent analytic model of cosmic string networks. In combination with recent simulations, this suggests that 90% of the string go...

Three-Body Encounters of Black Holes in Globular Clusters

Evidence has been mounting for the existence of black holes with masses from 102 to 104 M⊙ associated with stellar clusters. Such intermediate-mass black holes (IMBHs) will encounter other black holes in the dense cores of these clusters. The binaries produced in these interactions will be perturbed by other objects as well thus changing the orbital characteristics of the binaries. These binari...

LIGO at the threshold of science operations

LIGO held its first science run during the two and one-half week period from 23 August to 09 September 2002. The strain sensitivity of the interferometers during this observational period was h(f) ∼ 10−20 Hz− 1 2 at f ∼ 300Hz. The useful instrumental bandwidth spanned the decade 100Hz ∼< f ∼< 1000Hz. During the 17-day period, the three km-scale LIGO interferometers (4km and 2km in WA and 4km in...

Thermal Gravitational Waves

There is a lot of current interest in sources of gravitational waves and active ongoing projects to detect such radiation, such as the LIGO project. These are long wavelength, low frequency gravitational waves. LISA would be sensitive to much longer wavelengths and lower fluxes. However compact stellar objects can generate high frequency (10 16 -10 21 Hz) thermal gravitational radiation, which ...
