GROWTH observations of GW170817 The gravitational wave event GW170817 was caused by the merger of two neutron stars (see the Introduction by Smith). In three papers, teams associated with the GROWTH (Global Relay of Observatories Watching Transients Happen) project present their observations of the event at wavelengths from x-rays to radio waves. Evans et al. used space telescopes to detect GW170817 in the ultraviolet and place limits on its x-ray flux, showing that the merger generated a hot… 
A radio counterpart to a neutron star merger
TLDR
Radio observations constrain the energy and geometry of relativistic material ejected from a binary neutron star merger, and the detection of a counterpart radio source that appears 16 days after the event is reported, allowing us to diagnose the energetics and environment of the merger.
Illuminating gravitational waves: A concordant picture of photons from a neutron star merger
TLDR
It is demonstrated that merging neutron stars are a long-sought production site forging heavy elements by r-process nucleosynthesis, which is dissimilar to classical short gamma-ray bursts with ultrarelativistic jets.

TLDR
The reported observations, connecting GWs to both gamma-ray bursts (GRBs) and a long-theorized—but hitherto undetected—short-lived EM transient represents a watershed moment in astrophysics.

Swope Supernova Survey 2017a (SSS17a), the optical counterpart to a gravitational wave source
TLDR
A rapid astronomical search located the optical counterpart of the neutron star merger GW170817 and shows how these observations can be explained by an explosion known as a kilonova, which produces large quantities of heavy elements in nuclear reactions.
The X-ray counterpart to the gravitational-wave event GW170817
TLDR
The detection of X-ray emission at a location coincident with the kilonova transient provides the missing observational link between short γ-ray bursts and gravitational waves from neutron-star mergers, and gives independent confirmation of the collimated nature of the γ,ray-burst emission.

A kilonova as the electromagnetic counterpart to a gravitational-wave source
TLDR
Observations and physical modelling of a rapidly fading electromagnetic transient in the galaxy NGC 4993, which is spatially coincident with GW170817, indicate that neutron-star mergers produce gravitational waves and radioactively powered kilonovae, and are a nucleosynthetic source of the r-process elements.

TLDR
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.
