GRB 990123: The Case for Saturated Comptonization
Liang, E. P., Crider, A., Bottcher, M., and Smith, I. A.
We find that the optical magnitudes of GRB990123 observed by ROTSE move
in-tandem with the magnitudes extrapolated from the simultaneous BATSE
spectra, strongly suggesting that the optical, X-ray and gamma-ray
photons originate from a single source.
We show that the broadband optical-gamma-ray spectra can be naturally
modeled by the saturated Comptonization model and derive the parameters
of the Compton emitting shell from first principles.
