Specific Angular Momentum of Extrasolar Planetary Systems
John C. Armstrong, Shane L. Larson, Rhett R. Zollinger
As the number of known planetary systems increases, the ability to follow-up and characterize the extent of any system becomes limited. This paper considers the use of specific ang…
The LISA Gravitational Wave Foreground: A Study of Double White Dwarfs
A. J. Ruiter, K. Belczynski, M. Benacquista +2
Double white dwarfs are expected to be a source of confusion-limited noise for the future gravitational wave observatory LISA. In a specific frequency range, this 'foreground noise…
Selection effects in resolving Galactic binaries with LISA
M. J. Benacquista, S. L. Larson, B. E. Taylor
Using several realisations of the Galactic population of close white dwarf binaries, we have explored the selection bias for resolved binaries in the LISA data stream. We have assu…
Gravitational wave bursts from the Galactic massive black hole
Clovis Hopman, Marc Freitag, Shane L. Larson
The Galactic massive black hole (MBH), with a mass of Mbh=3.6\times10^6 Solar masses, is the closest known MBH, at a distance of only 8 kpc. The proximity of this MBH makes it poss…
Observing IMBH-IMBH Binary Coalescences via Gravitational Radiation
John M. Fregeau, Shane L. Larson, M. Coleman Miller +2
Recent numerical simulations have suggested the possibility of forming double intermediate mass black holes (IMBHs) via the collisional runaway scenario in young dense star cluster…
Contribution of Compact Mass Transferring Systems to the Galactic Gravitational Wave Background
Krzysztof Belczynski, Matthew Benacquista, Shane L. Larson +1
Compact object binaries, mostly double with dwarfs, are believed to be a potential source of confusion-limited noise for the Laser Interferometer Space Antenna (LISA). In a specifi…
Gravitational radiation timescales for extreme mass ratio inspirals
Jonathan R Gair, Daniel J Kennefick, Shane L Larson
The capture and inspiral of compact stellar masses into massive black holes is an important source of low-frequency gravitational waves (with frequencies of ~1-100mHz), such as tho…
Constraining the properties of the proposed supermassive black hole system in 3c66b: Limits from pulsar timing
Fredrick A. Jenet, Andrea Lommen, Shane L. Larson +1
Data from long term timing observations of the radio pulsar PSR B1855+09 have been searched for the signature of Gravitational waves (G-waves) emitted by the proposed supermassive…
LISA data analysis: Source identification and subtraction
Neil J. Cornish, Shane L. Larson
The Laser Interferometer Space Antenna (LISA) will operate as an AM/FM receiver for gravitational waves. For binary systems, the source location, orientation and orbital phase are…
Can gravitational waves be detected in quasar microlensing?
Shane L. Larson, Rudolph Schild
Studies of the lensed quasar have shown evidence for microlensing in the brightness history of the quasar images. It had been suggested that a frequency…
