Microscopic fluctuations inherent to the fuzziness of spacetime at the Planck scale might accumulate in wavefronts propagating a cosmological distance and lead to noticeable blurring in an image of a pointlike source. Distant quasars viewed in the optical and ultraviolet with Hubble Space Telescope (HST) may show this weakly, and if real suggests a stronger effect should be seen for gamma-ray bursts (GRBs) in X-rays and γ-rays. Those telescopes, however, operate far from their diffraction… Expand

If spacetime is “foamy” travel along a lightpath must be subject to continual, random distance fluctuations ± δ l proportional to Planck length l P ~ 10−35 m (Lieu & Hillman 2003). Although eachExpand
New constraints on quantum foam models from X-ray and gamma-ray observations of distant quasars
Astronomical observations of distant quasars may be important to test models for quantum gravity, which posit Planck-scale spatial uncertainties (’spacetime foam’) that would produce phaseExpand
A limit on Planck-scale froth with ESPRESSO
Some models of quantum gravity predict that the very structure of space–time is ‘frothy’ due to quantum fluctuations. Although the effect is expected to be tiny, if these space–time fluctuations growExpand


Potential Sensitivity of Gamma-Ray Burster Observations to Wave Dispersion in Vacuo
The recent confirmation that at least some gamma-ray bursters (GRBs) are indeed at cosmological distances raises the possibility that observations of these could provide interesting constraints onExpand
Evidence for Gamma-ray Halos Around Active Galactic Nuclei and the First Measurement of Intergalactic Magnetic Fields
Intergalactic magnetic fields (IGMFs) can cause the appearance of halos around the gamma-ray images of distant objects because an electromagnetic cascade initiated by a high-energy gamma-rayExpand
Limits on Spacetime Foam
Plausibly spacetime is foamy on small distance scales, due to quantum fluctuations. We elaborate on the proposal to detect spacetime foam by looking for seeing disks in the images of distant quasarsExpand
Are high-redshift quasars blurry?
It has been suggested that the fuzzy nature of spacetime at the Planck scale may cause light waves to lose phase coherence, and if severe enough this could blur images of distant pointlike sourcesExpand
Probing early cosmic magnetic fields through pair echoes from high‐redshift GRBs
We discuss the expected properties of pair echo emission from gamma-ray bursts (GRBs) at high redshifts (z ≳ 5), their detectability, and the consequent implications for probing intergalacticExpand
Tests of quantum gravity from observations of γ-ray bursts
The recent confirmation that at least some γ-ray bursts originate at cosmological distances suggests that the radiation from them could be used to probe some of the fundamental laws of physics. HereExpand
Using Observations of Distant Quasars to Constrain Quantum Gravity
Aims. The small-scale nature of spacetime can be tested with observations of distant quasars. We comment on a recent paper by Tamburini et al. (A&A, 533, 71) which claims that Hubble Space TelescopeExpand
Fermi-LAT Observations of the Gamma-Ray Burst GRB 130427A
Temporal and spectral analyses of GRB 130427A challenge the widely accepted model that the nonthermal high-energy emission in the afterglow phase of GRBs is synchrotron emission radiated by electrons accelerated at an external shock. Expand
A limit on the variation of the speed of light arising from quantum gravity effects
The detection of emission up to ∼31 GeV from the distant and short GRB, and no evidence for the violation of Lorentz invariance is found, which disfavour quantum-gravity theories in which the quantum nature of space–time on a very small scale linearly alters the speed of light. Expand
Determination of the Point-spread Function for the Fermi Large Area Telescope from On-orbit Data and Limits on Pair Halos of Active Galactic Nuclei
The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope is a pair-conversion telescope designed to detect photons with energies from ≈20 MeV to >300 GeV. The pre-launch responseExpand
