But the pomp will belie nagging problems that are likely to keep Virgo from joining its U.S. counterpart, the Laser Interferometer Gravitational - Wave Observatory (LIGO), in a hunt
for gravitational wave sources that was meant to start next month.
For the first time, theoretical physicists from the University of Basel have calculated the signal of
specific gravitational wave sources that emerged fractions of a second after the Big Bang.
Nature seems to behave as we would have expected, which is that it has produced not only a very
powerful gravitational wave source like what we have detected and are talking about now, but also a not - so - powerful one of the same kind.
Swope Supernova Survey 2017a (SSS17a), the optical counterpart to
a gravitational wave source.
A kilonova as the electromagnetic counterpart to
a gravitational wave source.
Early spectra of
the gravitational wave source GW170817: Evolution of a neutron star merger.
The Hubble Space Telescope has made at least three sets of observations in that vicinity, including one on August 22 seeking «observations of the first electromagnetic counterparts to
gravitational wave sources.»
«It ties this object to
the gravitational wave source beyond all reasonable doubt.»

Another of his recent work, on how to strategically point telescopes to find electromagnetic counterparts to
gravitational wave sources, was adapted for observations by the Very Large Array radio telescope in New Mexico, which successfully observed radio emission from the merger.
