0 Assigned ID: 630 ----- Attempting Submission 1 (Wed Jan 16 22:47:53 GMT 2019) ----- HST Phase I Proposal 630 (190114C.apt) successfully submitted. Receipt: # 630-1 Dear All, Please find attached an updated phaseII with a 1 orbit repeat of observations in F606W and F775W to replace those lost in visit 03. Ideally these observations will take place in the short window in mid June (12/13). However, if necessary later June will also suffice. Best Wishes, Andrew extended before to Jul 1. 2082838949 ----- Attempting Submission 1 (Fri Jan 25 21:17:34 GMT 2019) ----- ----- Attempting Submission 2 (Thu Feb 21 14:04:44 GMT 2019) ----- ----- Attempting Submission 3 (Tue Apr 09 20:38:46 GMT 2019) ----- ----- Attempting Submission 4 (Thu Apr 25 15:45:22 GMT 2019) ----- The progenitor and physics of the first TeV gamma-ray burst The detection by the MAGIC telescope of GRB 190114C, with photons approaching TeV energies, marks it as the first GRB to create luminous emission in this extreme energy range. 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. 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.
