We examine a method to detect the light speed variation from gamma ray burst data observed by the Fermi Gamma-ray Space Telescope (FGST). We suggest new criteria to determine the characteristic time for low energy photons by the energy curve and the average energy curve, and obtain similar results compared with those from the light curve. We offer a new criterion with both the light curve and the average energy curve to determine the characteristic time for low energy photons. We then apply the new criteria to the GBM NaI data, the GBM BGO data, and the LAT LLE data, and obtain consistent results for three different sets of low energy photons from different FERMI detectors.

  1. New analysis of SNeIa Pantheon Catalog: Variable speed of light as an alternative to dark energy

    astro-ph.CO 2024-12 reject novelty 6.0 of 10

    A variable-speed-of-light model with a modified Lemaître redshift formula fits the Pantheon supernova catalog with H0 ≈ 47 and no dark energy.

    A combined model with both Lorentz-violation and energy-dependent intrinsic delays recovers simulated parameters across all mock datasets and fits multi-GeV and TeV GRB photons, yielding a subluminal LV scale of about...

  3. Examining Lorentz invariance violation with three remarkable GRB photons

    astro-ph.HE 2025-04 conditional novelty 4.0 of 10

    Adding three extreme GRB photons preserves the fitted Lorentz-violation scale E_LV ~ 3e17 GeV, but only when an energy-dependent intrinsic delay term, itself a fitting construct, absorbs the new TeV photons.
