The Gravitationally-lensed Gravitational Wave Hunters collaboration
report observations of strong-lensing galaxy clusters located within the
sky localisation of the LIGO/Virgo trigger G296853 (LVC GCN Circ. 21413).
Following Smith et al. (arXiv:1707.03412) we searched the skymap for
strong-lensing galaxy clusters that lie within the 90% credible sky
localisation. Abell 2895 was the closest strong-lensing galaxy cluster
to the peak probability in the skymap. We observed this cluster with
MUSE on VLT on the nights of August 9, 14, and 16. MUSE spans a 1x1
arcminute field of view with a wavelength range of 4650-9300 Angstroms.
Analysis of these data is ongoing. Colleagues with complementary data
are welcome to contact us with a view to collaboration.
We thank the staff at ESO for their outstanding support of our observing
programmes.
