Abstract
We present a comprehensive multiwavelength analysis of the bright, long duration gamma‐ray burst GRB 070125, comprised of observations in γ‐ray, X‐ray, optical, millimeter and centimeter wavebands. Radio light curves show rapid flux variations, which are interpreted as due to interstellar scintillation, and are used to derive an upper limit of 2.4×1017 cm on the radius of the fireball. Radio light curves and spectra suggest that the afterglow shock wave is moving in a dense medium. Our broadband modeling favors a constant density profile for the circumburst medium over a wind‐like profile (R−2). GRB 070125 is a burst with high radiative efficiency (>60%).
