LIGO A: Detector Design and Science Prospects Beyond A+
L. Sun, K. Kuns, B. J. J. Slagmolen +1153
We present the LIGO A detector concept, an upgrade for the LIGO observatories based on room-temperature interferometers beyond the fifth observing run (O5). Building on th…
A Foundation for Gravitational-Wave Population Inference within the LISA Global Fit
Alexander W. Criswell, Sharan Banagiri, Vera Delfavero +3
Population inference in gravitational-wave astronomy allows us to connect individual detections to the astrophysics of compact objects and their environments. Current approaches em…
Flexible Spectral Separation of Multiple Isotropic and Anisotropic Stochastic Gravitational Wave Backgrounds in LISA
Alexander W. Criswell, Sharan Banagiri, Jessica Lawrence +4
The Laser Interferometer Space Antenna (LISA) will observe mHz gravitational waves from a wide variety of astrophysical sources. Of these, some will be characterizable as individua…
A Unified for Gravitational Waves: Consistently Combining Information from Multiple Search Pipelines
Sharan Banagiri, Christopher P. L. Berry, Gareth S. Cabourn Davies +2
Recent gravitational-wave transient catalogs have used \pastro{}, the probability that a gravitational-wave candidate is astrophysical, to select interesting candidates for further…
Mapping the Gravitational-wave Sky with LISA: A Bayesian Spherical Harmonic Approach
Sharan Banagiri, Alexander Criswell, Tommy Kuan +3
The millihertz gravitational-wave frequency band is expected to contain a rich symphony of signals with sources ranging from galactic white dwarf binaries to extreme mass ratio ins…
LIGO Detector Characterization in the Second and Third Observing Runs
D. Davis, J. S. Areeda, B. K. Berger +284
The characterization of the Advanced LIGO detectors in the second and third observing runs has increased the sensitivity of the instruments, allowing for a higher number of detecta…
Environmental Noise in Advanced LIGO Detectors
P. Nguyen, R. M. S. Schofield, A. Effler +215
The sensitivity of the Advanced LIGO detectors to gravitational waves can be affected by environmental disturbances external to the detectors themselves. Since the transition from…
Sensitivity and Performance of the Advanced LIGO Detectors in the Third Observing Run
LIGO Instrument Science List, :, A. Buikema +197
On April 1st, 2019, the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO), joined by the Advanced Virgo detector, began the third observing run, a year-long dedi…
Reducing Scattered Light in LIGO's Third Observing Run
S Soni, C Austin, A Effler +195
Noise due to scattered light has been a frequent disturbance in the Advanced LIGO gravitational wave detectors, hindering the detection of gravitational waves. The non stationary s…
Bayesian inference for compact binary coalescences with BILBY: Validation and application to the first LIGO--Virgo gravitational-wave transient catalogue
I. M. Romero-Shaw, C. Talbot, S. Biscoveanu +56
Gravitational waves provide a unique tool for observational astronomy. While the first LIGO--Virgo catalogue of gravitational-wave transients (GWTC-1) contains eleven signals from…
Constraining the Gravitational-Wave Afterglow From a Binary Neutron Star Coalescence
Sharan Banagiri, Michael W. Coughlin, James Clark +5
Binary neutron star mergers are rich laboratories for physics, accessible with ground-based interferometric gravitational-wave detectors such as the Advanced LIGO and Advanced Virg…
Search strategies for long gravitational-wave transients: hidden Markov model tracking and seedless clustering
Sharan Banagiri, Ling Sun, Michael W. Coughlin +1
A number of detections have been made in the past few years of gravitational waves from compact binary coalescences. While there exist well-understood waveform models for signals f…
Multi-wavelength observations of cosmological phase transitions using LISA and Cosmic Explorer
Margot Fitz Axen, Sharan Banagiri, Andrew Matas +2
We reanalyze the detection possibilities for gravitational waves arising from cosmological first order phase transitions. We discuss the stochastic gravitational wave background co…
