You may already have heard on the news that a new gravitational wave
detection was made, this time not only by the two LIGO detectors but
also by the VIRGO detector in Italy; this allowed it to be roughly
triangulated to a position on the sky where the event was then found by
telescopes. As a result the same event (termed a "kilo-nova", the first
ever observed) has been detected as electromagnetic radiation at
wavelengths all the way from microwaves to gamma rays. This is
summarized in the following lengthy press release from the LIGO
gravitational wave observatory:

Nobel prizes were recently awarded to scientists responsible for the
detection of gravitational waves, predicted by Einstein a hundred years
ago. But the following concerns more the detection of the same event by
telescopes and includes full-text links to the resulting astronomy
papers that are being published in Nature etc.:

ESO Telescopes Observe First Light from Gravitational Wave Source
Merging neutron stars scatter gold and platinum into space
16 October 2017
ESO’s fleet of telescopes in Chile have detected the first visible
counterpart to a gravitational wave source. These historic observations
suggest that this unique object is the result of the merger of two
neutron stars. The cataclysmic aftermaths of this kind of merger —
long-predicted events called kilonovae — disperse heavy elements such as
gold and platinum throughout the Universe. This discovery, published in
several papers in the journal Nature and elsewhere, also provides the
strongest evidence yet that short-duration gamma-ray bursts are caused
by mergers of neutron stars.....
