At a redshift of z=0.41, scattering off the extragalactic background light (EBL) should greatly diminish the luminosity at this energy, and its detection is either implying something about fundamental physics, or suggesting an event which can create a truly exceptional high energy component. Here we propose a programme of HST observations that will dissect the details of this explosion; we will track the source as it fades into its host, determine the true energy (through the detection of any so-called jet-break) and disentangle the afterglow from any associated supernova. These observations will constrain the physics of the GRB emission and compare the properties of the progenitor star - through its supernova -- with those of other GRBs. Together this will enable us to test the origin of this extreme burst. Hot on the heels of the detection of gravitational waves and high energy neutrinos this detection of TeV photons from a GRB further highlights how new technologies enable insights into hitherto inaccessible areas of science. ------------------------------------------------------------------------------------ Observations Description ------------------------ Our aim is to characterise the afterglow, supernova and host galaxy of GRB 190114C, the first GRB to be detected at GeV energies. We will do this via imaging and grism spectroscopy. Our first epoch will consist of two orbits of grism spectroscopy using a 4-point dither (and also obtaining two direct images in F606W). A second visit will contain imaging observations in F475W/F775W and F850LP. Combined these will allow us to measure the properties of any associated supernova as well as obtaining a blue point which will provide a better measurement of the afterglow light. These images will also charaterize the morphology of the host galaxy. Beyond this we intend to obtain two further epochs of imaging (1 orbit each), with the precise strategy dictacted by the outcome of earlier observations (both on the ground and with HST). These will be requested with a >3 week turnaround. ------------------------------------------------------------------------------------ 15684( 5) - 25-Apr-2019 15:51:45 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 GRB190114C EXT-STAR, GAMMA RAY RA=03H38M1.1600S, J2000 V = 22 +/- 2 BURSTER DEC=-26D56'46.90" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 15684( 5) -
