The ECLAIRs micro-satellite for multi-wavelength studies of gamma-ray burst prompt emission
S. Schanne, J. -L. Atteia, D. Barret +15
The cosmological revolution of 1997 has established that (at least long duration) gamma-ray bursts (GRB) are among the most energetic events in the Universe and occur at cosmologic…
Probing the time-variation of the fine-structure constant: Results based on Si IV doublets from a UVES sample
Hum Chand, Patrick Petitjean, Raghunathan Srianand +1
We report a new constraint on the variation of the fine-structure constant based on the analysis of 15 Si IV doublets selected from a ESO-UVES sample. We find Δα/α= (+0.15+/-0.43)…
Limits on the time variation of the electromagnetic fine-structure constant in the low energy limit from absorption lines in the spectra of distant quasars
Raghunathan Srianand, Hum Chand, Patrick Petitjean +1
Most of the successful physical theories rely on the constancy of few fundamental quantities (such as the speed of light, , the fine-structure constant, α, the proton to electro…
