BATSE Evidence for GRB Spectral Features
arXiv:astro-ph/9712096 · doi:10.1063/1.55338
Abstract
We have developed an automatic search procedure to identify low-energy spectral features in GRBs. We have searched 133,000 spectra from 117 bright bursts and have identified 12 candidate features with significances ranging from our threshold of P = 5E-5 to P = 1E-7. Several of the candidates have been examined in detail, including some with data from more than one BATSE spectroscopy detector. The evidence for spectral features appears good; however, the features have not conclusively been shown to be narrow lines.
