The massive comma compact galaxy Makani hosts one of the largest CORCHETE_OPENOIICORCHETE_CLOSE nebulae comma and perhaps the largest starburst-driven galactic wind comma yet detected. This wind extends well into the CGM of its host (r_wind > 20r_stars) and is a snapshot of the CGM-in-formation. The cool comma dense medium of the wind-CGM interface in Makani (traced in emission by CORCHETE_OPENOIICORCHETE_CLOSE comma MgII comma and CO emission) on scales of 100 kpc show an outflow forming the cool CGM in real time. Much of our knowledge of the CGM in other galaxies is derived from statistical studies of the warm-hot (10elev5-10elev6 K) phase. The enormous and lumionus oxygen nebula in Makani is the ideal target to *image* the warm-hot CGM comma which is difficult in most other sources. We propose to make the first d_commarebirth picture.. of the warm-hot CGM as it is being formed anew by the giant wind in Makani. We will image Makani in OVI 1032 comma 1038 A with ACS-SBC comma a technique that recently yielded the first OVI image of the halo of a starburst galaxy (Hayes et al. 2016). We will apply the same synthetic narrowband technique which is perfectly suited for Makani comma whose observed-frame OVI line (at z=0.459) lies at the peak of the F150LP filter. These observations are optimally-timed to meet simulated images of OVI that are emerging from the latest simulations. The morphology of the OVI image and line flux ratios with CORCHETE_OPENOIICORCHETE_CLOSE will constrain the physical state of the gas in the nebula through comparison with models and simulations of the wind-CGM interaction and shock+photoionization models.
