title = "GRB 041219A: Its host galaxy and its broad-band prompt optical-to-gamma-ray emission",
abstract = "GRB 041219A is one of the longest and brightest gamma-ray bursts (GRBs) ever observed. It was discovered by the INTEGRAL satellite, and, thanks to a precursor happening about 300 s before the bulk of the burst, ground based telescopes were able to catch the rarely-observed prompt emission in the optical and in the near-infrared bands. Here we present the late-time multi-band near-infrared imaging data, collected at the CFHT, that allowed us to identify the host galaxy of the GRB as an under-luminous, irregular galaxy of ∼ 5 × 109M⊙ at best-fit redshift of z = 0.31 -0.26+0.54. In addition we model the broad-band prompt optical to γ-ray emission of GRB 041219A within the internal shock model, where we were able to reproduce the spectra and light curve invoking the synchrotron emission of relativistic electrons accelerated by a series of propagating shock waves inside a relativistic outflow.",
