GRBs in the Era of Rapid Response Telescopes
NASA's Swift and Fermi satellites continue to chase gamma-ray bursts (GRBs) and make ground-breaking discoveries. The resulting science has been greatly enhanced by follow-up studies and coincident event searches from a variety of observatories, including RAPTOR, Watcher, REM, Pi of the Sky, MASTER, iPTF, GROND, GTC, RATIR, DCT, Asiago, Nanshan, Liverpool Robotic Telescope, KAIT, NOT, Gemini, Magellan, Keck, VLT, VLA, ACTA, ALMA, AMI, WSRT, GMRT, CARMA, LOFAR, HAWC, VERITAS, MAGIC, HESS, IceCube, ANTARES, LIGO, HST, Chandra, Spitzer, Fermi, AGILE, INTEGRAL, NuSTAR, IPN, MAXI, CALET, and AstroSAT. These observatories have added to our knowledge of the early-time behavior of GRBs, such as the short-lived reverse-shock which has been seen now in a small handful of the brightest bursts. The emphasis on longer term optical observations, days to weeks after the burst, has increased with the prospects in a few years for multiple active gravitational wave observatories providing good localizations for compact object mergers, and the potential for seeing the isotropic kilonova emission if one of the objects is a neutron star.

Challenging the Forward Shock Model with the 80 Ms Follow up of the X-ray Afterglow of Gamma-Ray Burst 130427A
GRB 130427A was the most luminous gamma-ray burst detected in the last 30 years. With an isotropic energy output of erg and redshift of 0.34, it combined very high energetics with a relative proximity to Earth in an unprecedented way. Sensitive X-ray observatories such as XMM-Newton and Chandra have detected the afterglow of this event for a record-breaking baseline longer than 80 million seconds. The light curve displays a simple power-law over more than three decades in time. In this presentation, we explore the consequences of this result for a few models put forward so far to interpret GRB 130427A, and more in general the implication of this outcome in the context of the standard forward shock model.Open AccessChallenging the Forward Shock Model with the 80 Ms Follow up of the X-ray Afterglow of Gamma-Ray Burst 130427A

Perspectives on Gamma-Ray Burst Physics and Cosmology with Next Generation Facilities
High-redshift Gamma-Ray Bursts (GRBs) beyond redshift $\sim6$ are potentially powerful tools to probe the distant early Universe. Their detections in large numbers and at truly high redshifts call for the next generation of high-energy wide-field instruments with unprecedented sensitivity at least one order of magnitude higher than the ones currently in orbit. On the other hand, follow-up observations of the afterglows of high-redshift GRBs and identification of their host galaxies, which would be difficult for the currently operating telescopes, require new, extremely large facilities of at multi-wavelengths. This chapter describes future experiments that are expected to advance this exciting field, both being currently built and being proposed. The legacy of Swift will be continued by SVOM, which is equipped with a set of space-based multi-wavelength instruments as well as and a ground segment including a wide angle camera and two follow-up telescopes. The established Lobster-eye X-ray focusing optics provides a promising technology for the detection of faint GRBs at very large distances, based on which the {THESEUS}, {Einstein Probe} and other mission concepts have been proposed. Follow-up observations and exploration of the reionization era will be enabled by large facilities such as {SKA} in the radio, the 30m class telescopes in the optical/near-IR, and the space-borne {WFIRST} and {JWST} in the optical/near-IR/mid-IR. In addition, the X-ray and $\gamma$-ray polarization experiment POLAR is also introduced.Open AccessPerspectives on Gamma-Ray Burst Physics and Cosmology with Next Generation Facilities

Wide-Field InfraRed Survey Telescope (WFIRST) Mission and Synergies with LISA and LIGO-Virgo
The Wide-Field InfraRed Survey Telescope (WFIRST) is a NASA space mission in study for launch in 2024. It has a 2.4 m telescope, wide-field IR instrument operating in the 0.7 - 2.0 micron range and an exoplanet imaging coronagraph instrument operating in the 400 - 1000 nm range. The observatory will perform galaxy surveys over thousands of square degrees to J=27 AB for dark energy weak lensing and baryon acoustic oscillation measurements and will monitor a few square degrees for dark energy SN Ia studies. It will perform microlensing observations of the galactic bulge for an exoplanet census and direct imaging observations of nearby exoplanets with a pathfinder coronagraph. The mission will have a robust and well-funded guest observer program for 25% of the observing time. WFIRST will be a powerful tool for time domain astronomy and for coordinated observations with gravitational wave experiments. Gravitational wave events produced by mergers of nearby binary neutron stars (LIGO-Virgo) or extragalactic supermassive black hole binaries (LISA) will produce electromagnetic radiation that WFIRST can observe.

Gamma-ray bursts in the swift-Fermi era
Gamma-ray bursts (GRBs) are among the most violent occurrences in the universe. They are powerful explosions, visible to high redshift, and thought to be the signature of black hole birth. They are highly luminous events and provide excellent probes of the distant universe. GRB research has greatly advanced over the past 10 years with the results from Swift, Fermi and an active followup community. In this review we survey the interplay between these recent observations and the theoretical models of the prompt GRB emission and the subsequent afterglows.
