... Spectra of gamma-ray burst afterglow are modeled taking into account conversion of hard photons (soft X-ray, hard UV) to soft UV and optics photons.. ...
... multiwavelength monitoring campaign on NGC7469 showed optical continuum variations lagging behind those in the UV by about 1d at 4800A and about 2d at 7500A. These UV/optical continuum lags imply a radial temperature structure T ~ R -3/4 , consistent with ...
