Limits on the cosmological abundance of supermassive compact objects from a millilensing search in gamma-ray burst data
Robert J. Nemiroff, Gabriela F. Marani, Jay P. Norris +1
A new search for the gravitational lens effects of a significant cosmological density of supermassive compact objects (SCOs) on gamma-ray bursts has yielded a null result. We inspe…
GLAST, GRBs, and Quantum Gravity
J. P. Norris, J. T. Bonnell, G. F. Marani +1
The fast temporal structures and cosmological distances of gamma-ray bursts (GRBs) afford a natural laboratory for testing theories of frequency-dependent propagation of high-energ…
Connection Between Energy-dependent Lags And Peak Luminosity In Gamma-ray Bursts
J. P. Norris, G. F. Marani, J. T. Bonnell
We suggest a connection between the pulse paradigm at gamma-ray energies and the recently demonstrated luminosity distribution in gamma-ray bursts: the spectral evolution timescale…
Gravitationally Lensed Gamma-Ray Bursts as Probes of Dark Compact Objects
G. F. Marani, R. J. Nemiroff, J. P. Norris +2
If dark matter in the form of compact objects comprises a large fraction of the mass of the universe, then gravitational lensing effects on gamma-ray bursts are expected. We utiliz…
GRB Spikes Could Resolve Stars
Robert J. Nemiroff, Jay P. Norris, Jerry T. Bonnell +1
GRBs vary more rapidly than any other known cosmological phenomena. The lower limits of this variability have not yet been explored. Improvements in detectors would reveal or limit…
