Abstract:

LALinference sky localizations of three O1 and two O2 binary black hole signals: GW150914, LVT151012, GW151226, GW170104, GW170814. Note the considerably smaller location uncertainty for GW170814 because it was the first signal that was also detected by Advanced Virgo. The background is Mellinger's optical image of the Milky Way, shown at the time of GW151226 (in other words, all three sky localizations are shifted to the sidereal time of GW151226). Note that the localizations of GW150914, LVT151012, and GW170104 wrap around the celestial sphere, so the sky map is shown with a translucent sky dome.

The font is Source Sans Pro Light.
