Going the Distance: Mapping Host Galaxies of LIGO Sources in Three Dimensions Using Local Cosmography and Targeted Follow-up and the accompanying Supplement paper.
The paper explores three-dimensional reconstruction positions of gravitational-wave transients that are detectable by LIGO and Virgo. It builds upon an earlier pair of papers on sky localization with gravitational-wave detectors, but adds directionally resolved LIGO distance estimates in order to facilitate deep searches of potential host galaxies for electromagnetic counterparts of LIGO sources.
The table below shows thumbnail images of 500 simulated Advanced LIGO volume reconstructions. Each image is a volume rendering of the probability distribution for a given event, projected in the plane of the distribution's two most significant principal axes.

Sort by buttons to reorder the thumbnails by detector network, enclosed volume, enclosed area, network signal-to-noise ratio, or signal-to-noise ratio in LIGO Hanford (H) or LIGO Livingston (L).
Touch any thumbnail to show more detail about the simulated event or to download the FITS/HEALPix sky localization file.
Alternatively, you can download a
.tar archive of all of the sky maps for O1 (9.7GB) or O2 (9.6GB).
The 3D localization files are easy to use in Python using the Healpy package. See sample code for usage details or the Supplement paper for detailed usage and file format details.
