GrailQuest (Gamma Ray Astronomy International Laboratory for QUantum Exploration of Space-Time) is a mission concept based on a constellation (hundreds/thousands) of nano/micro/small-satellites in low (or near) Earth orbits. Each satellite hosts a non-collimated array of scintillator crystals coupled with Silicon Drift Detectors with broad energy band coverage (keV-MeV range) and excellent temporal resolution (≤ 100 nanoseconds) each with effective area $\sim 100 \text {cm}^{2}$ ∼ 100 cm… 

Studying the variation of fundamental constants at the Cosmic Ray Extremely Distributed Observatory

The study of the variation of fundamental constants through time or in localized regions of space is one of the goals of the Cosmic Ray Extremely Distributed Observatory which consists of multiple

Key Space and Ground Facilities in GRB Science

Gamma-ray bursts (GRBs) are short and intense flashes of γ-rays coming from deep space. GRBs were discovered more than a half century ago and now are observed across the whole electromagnetic

Covariant Space-Time Line Elements in the Friedmann-Lemaitre-Robertson-Walker Geometry

Most quantum gravity theories endow space-time with a discreet nature by space quantization on the order of Planck length (lp ). This discreetness could be demonstrated by confirmation of Lorentz

Testing fundamental physics with astrophysical transients

Explosive astrophysical transients at cosmological distances can be used to place precision tests of the basic assumptions of relativity theory, such as Lorentz invariance, the photon zero-mass

GrailQuest and HERMES: hunting for gravitational wave electromagnetic counterparts and probing space-time quantum foam

Within Quantum Gravity theories, different models for space-time quantisation predict an energy dependent speed for photons. Although the predicted discrepancies are minuscule, GRB, occurring at

Timing techniques applied to distributed modular high-energy astronomy: the H.E.R.M.E.S. project

TLDR
Here the authors discuss in detail dedicated timing techniques that allow to precisely locate an astronomical event in the sky taking advantage of the spatial distribution of a swarm of detectors orbiting Earth.

The HERMES-technologic and scientific pathfinder

HERMES-TP/SP is a constellation of six 3U nano-satellites hosting simple but innovative X-ray detectors for the monitoring of Cosmic High Energy transients such as Gamma Ray Bursts and the

The future of astronomy with small satellites

TLDR
The potential for small satellites to explore new parameter spaces in astrophysics is discussed, drawing on examples from current and proposed missions, and spanning a wide range of science goals from binary stars, exoplanets and solar system science to the early Universe and fundamental physics.

Stars whose masses are of the same order as that of the sun (M ) can find a final equilibrium state either as a white dwarf or, apparently, (after collapse and ejection of material) as a neutron

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. Here

Gamma-Ray Bursts Have Millisecond Variability

We have performed searches for isolated flares and for steady flickering in the initial ~1 s of gamma-ray burst light curves on the microsecond to millisecond timescales. Two bursts among our sample

A limit on the variation of the speed of light arising from quantum gravity effects

TLDR
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.

For the first time, the nature of gravitational-wave polarizations from the antenna response of the LIGO-Virgo network is tested, thus enabling a new class of phenomenological tests of gravity.
