A Case Study of On-the-Fly Wide-Field Radio Imaging Applied to the Gravitational-wave Event GW 151226
We apply a newly-developed On-the-Fly mosaicing technique on the NSF's Karl G. Jansky Very Large Array (VLA) at 3 GHz in order to carry out a sensitive search for an afterglow from the Advanced LIGO

Swift and NuSTAR observations of GW170817: Detection of a blue kilonova
Ultraviolet and x-ray observations of a binary neutron star merger show a hot kilonova but no jet along the line of sight, which avoids both obscuration from the heaviest elements in the orbital plane and a direct view of any ultrarelativistic, highly collimated ejecta.
Radio follow-up of gravitational wave triggers during Advanced LIGO O1
We present radio follow-up observations carried out with the Karl G. Jansky Very Large Array during the first observing run (O1) of the Advanced Laser Interferometer Gravitational-wave Observatory
2SXPS: An Improved and Expanded Swift X-Ray Telescope Point-source Catalog
We present the 2SXPS (Swift-XRT Point Source) catalog, containing 206,335 point sources detected by the Swift X-ray Telescope (XRT) in the 0.3--10 keV energy range. This catalog represents a
GW170817: Swift UV detection of a blue kilonova, and improving the search in O3
Abstract Swift’s rapid slewing, flexible planning, and multi-wavelength instruments make it the most capable space-based follow-up engine for finding poorly localized sources. During O1 and O2 Swift
An optimised gravitational wave follow-up strategy with the Australian Square Kilometre Array Pathfinder
Possibility for detecting both prompt and long-term radio emission from neutron star mergers with Australian Square Kilometre Array Pathfinder are explored and an observing strategy that optimises the use of telescope time is determined.
Where and when: optimal scheduling of the electromagnetic follow-up of gravitational-wave events based on counterpart lightcurve models
The electromagnetic (EM) follow-up of a gravitational wave (GW) event requires to scan a wide sky region, defined by the so called "skymap", for the detection and identification of a transient


Optimization of the Swift X-ray follow-up of Advanced LIGO and Virgo gravitational wave triggers in 2015-16
One of the most exciting near-term prospects in physics is the potential discovery of gravitational waves by the advanced LIGO and Virgo detectors. To maximise both the confidence of the detection

The Swift gamma-ray burst mission
The Swift mission will determine the origin of GRB, classify GRBs and search for new types, study the interaction of the ultrarelativistic outflows of GRBs with their surrounding medium, and use GRBs to study the early universe out to z >10.
We anticipate the first direct detections of gravitational waves (GWs) with Advanced LIGO and Virgo later this decade. Though this groundbreaking technical achievement will be its own reward, a still
Using the 2-MASS photometric redshift survey to optimize LIGO follow-up observations
The initial discovery of LIGO on 14 September 2015 was the inspiral merger and ring-down of the black hole binary at a distance of about 500~Mpc or a redshift of about 0.1. The search for
Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO and Advanced Virgo
A possible observing scenario for the Advanced LIGO and Advanced Virgo gravitational-wave detectors over the next decade is presented, and the expected sensitivity of the network to transient gravitational- wave signals is determined, and its capability to determine the sky location of the source is studied.
