A limit on the variation of the speed of light arising from quantum gravity effects
- A. Abdo, M. Ackermann, +205 authors M. Ziegler

- Nature
- 19 November 2009
A cornerstone of Einstein’s special relativity is Lorentz invariance—the postulate that all observers measure exactly the same speed of light in vacuum, independent of photon-energy. While special… Expand
The X-ray counterpart to the gravitational-wave event GW170817
A long-standing paradigm in astrophysics is that collisions—or mergers—of two neutron stars form highly relativistic and collimated outflows (jets) that power γ-ray bursts of short (less than two… Expand
The outflow structure of GW170817 from late-time broad-band observations
We present our broad-band study of GW170817 from radio to hard X-rays, including NuSTAR and Chandra observations up to 165 d after the merger, and a multimessenger analysis including LIGO… Expand
The Third Swift Burst Alert Telescope Gamma-Ray Burst Catalog
- A. Lien, T. Sakamoto, +12 authors T. Ukwatta
- Physics
- 6 June 2016
To date, the Burst Alert Telescope (BAT) onboard Swift has detected ~ 1000 gamma-ray bursts (GRBs), of which ~ 360 GRBs have redshift measurements, ranging from z = 0.03 to z = 9.38. We present the… Expand
Localization and broadband follow-up of the gravitational-wave transient GW150914
- B. Abbott, R. Abbott, +1,514 authors S. Rosswog
- Physics
- 26 February 2016
A gravitational-wave (GW) transient was identified in data recorded by the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) detectors on 2015 September 14. The event, initially… Expand
XMM-Newton observations of the supernova remnant IC 443: II. evidence of stellar ejecta in the inner regions.
- E. Troja, F. Bocchino, M. Miceli, F. Reale
- Physics
- 7 April 2008
Aims. We investigate the spatial distribution of the physical and chemical properties of the hot X-ray emitting plasma of the supernova remnant IC 443, in order to get important constraints on its… Expand
PRECURSORS OF SHORT GAMMA-RAY BURSTS
- E. Troja, S. Rosswog, N. Gehrels
- Physics
- 7 September 2010
We carried out a systematic search of precursors on the sample of short gamma-ray bursts (GRBs) observed by Swift. We found that ~8%-10% of short GRBs display such early episodes of emission. One… Expand
A luminous blue kilonova and an off-axis jet from a compact binary merger at z = 0.1341
- E. Troja, G. Ryan, +9 authors S. Veilleux
- Physics, Medicine
- Nature Communications
- 27 June 2018
The recent discovery of a gamma-ray burst (GRB) coincident with the gravitational-wave (GW) event GW170817 revealed the existence of a population of low-luminosity short duration gamma-ray transients… Expand
A Jet Break in the X-Ray Light Curve of Short Grb 111020a: Implications for Energetics and Rates
- W. Fong, E. Berger, +8 authors P. Podsiadlowski
- Physics
- 24 April 2012
We present broadband observations of the afterglow and environment of the short GRB 111020A. An extensive X-ray light curve from Swift/XRT, XMM-Newton, and Chandra, spanning {approx}100 s to 10 days… Expand
The fast, luminous ultraviolet transient AT2018cow: extreme supernova, or disruption of a star by an intermediate-mass black hole?
- D. Perley, P. Mazzali, +60 authors Jerrick Wee
- Physics
- 2 August 2018
Wide-field optical surveys have begun to uncover large samples of fast (t_rise 10 days. The spectrum remains extremely hot throughout its evolution, and the photospheric radius contracts with time… Expand
