'macronova') driven by the radioactive decay of newly-synthesised r-process elements. This directly supports the compact object merger hypothesis for short-duration GRBs, in which dynamically ejected neutron star material powers a radioactive transient. If confirmed in future events, this discovery also provides empirical evidence for a quasi-isotropic, electromagnetic signature of a prime target for gravitational wave (GW) detection by aLIGO/AdV, and suggests that kilonovae of this sort are likely sites of substantial (perhaps dominant) production of r-process elements in the universe. However, the ubiquity and range of behaviour of these events is entirely unknown; the kilonova luminosity is expected to depend on the ejecta mass and velocity, and also may be enhanced by ongoing energy input from the compact remnant. We need to establish their properties to inform searches of GW error boxes and quantify their contribution to the heavy element nucleosynthesis budget. Suitable SGRBs targets are rare, so intensive follow-up of any that occur is critical. Here we propose ToO observations (continuing our c23 campaign) of a low-redshift (z<~0.35) SGRB localised during cycle 24 to search for and characterise more fully any accompanying kilonova signal. ------------------------------------------------------------------------------------ Observations Description ------------------------ The aim of this proposal is to search for and characterise the nature of 14771( 9) - 21-Jun-2018 20:12:39 - [ 2] r-process kilonova in the afterglows of short duration GRBs. To do this we wish to search for IR re-brightenings indicative of heavily absorbed r-process production. Such a search requires that the source reddens and then rebrightens in the IR. Since these objects remain poorly studied (only a single example with little coverage) we have specified a range of observations. The choice of which observation to trigger will be based on the redshift of the burst (in particular to distinguish observations where grism observations are possible), any knowledge of the burst location within the host galaxy, foreground extinction etc. In general we will trigger two IR and one optical observation for monitoring. We have specified two sets of observations so that observations can be repeated later for subtraction of the light. Below we list the observations that have been specified. Please note that this is a superset of those we will actually perform, and that our total useage will not exceed 12 orbits. Note: That in our formal phase I proposal we did ask for the filters below, although not all were included in the dummy observations at the front of phase 1.
