These observations will track the likely rapidly fading counterparts to levels a factor 10 fainter than possible from the ground. They will determine the spectral and temporal evolution, evaluate their power sources, ascertain their contribution to the production of heavy elements in the Universe, pinpoint them on their host galaxies, characterise their environments and provide information to hone further searches. These observations will provide a unique and powerful view of a newly discovered, but long awaited class of astronomical object. ------------------------------------------------------------------------------------ Observations Description 15347( 6) - 16-Mar-2020 13:17:40 - [ 2] ------------------------ This is a proposal to obtain HST observations of the first electromagnetic counterparts to gravitational wave sources. It is a disruptive ToO programme, with the first observations taking place after a few days (3-6 after trigger) and subsequent observations at ~1 week intervals, with some later time follow-up Our programme envisages different strategies depending on the nature of the counterpart, and we outline these below. However, as this is a new field, and there is very limited information about the nature of the counterparts it may be necessary to tweak this stragegy at the time of trigger in order to ensure the highest possible scientific return. Rapid follow-up 1) Optical/IR counterpart discovery In this case we will likely trigger IR spectroscopy to search for kilonova emission. This will be through visits G1 and G2 which call for G102 and G141 grism spectroscopy as well as short direct images in F125W and F160W. Our later observations will be imaging in F125W and F160W (visits I1 and I2) to track the lightcurve. If the source is very faint, then we may omit the grism spectroscopy and use the X visits in F140W instead. 2) X-ray only counterpart discovery Here we assume that deep optical observations at the counterpart location have failed to identify a optical counterpart. In this case we will conduct a deep imaging search with HST. This will use visits X1-X4 (1 and 2 orbit visits in F140W) in order to conduct a deep search for any kilonova emission. Slow follow-up Once the initial observations are complete we will map the evolution of the counterpart for as long as it is visible to HST. We will use optical or IR filters for this as appropriate. For these later observations we will use single orbit integrations in each filter (vists I3-I7, possibly repeated as necessary). At very late times we will also characterise the environment of the transient. For this we may use UV observaitons and narrow band observations to search for star formation at the transient location (visits N1-N3 depending on the redshift of the source). ------------------------------------------------------------------------------------ 15347( 6) -
