The galaxies are selected from SAGA, an ongoing survey to characterize the low-luminosity dwarf galaxy satellites around Milky Way analogs. We have identified a set of QSO sightlines to study the gaseous halos of these Milky Way-like hosts and their satellites. The proposed FUV-bright QSOs are within the virial radius (~300 kpc) of each system. Armed with the combination of a complete satellite luminosity function for these hosts (M_V < -12) and the corresponding satellites' velocities, we will be in the unique position to directly compare CGM kinematics to that of the host halo. This is only possible because the satellite systems are fully characterized and matched simulations are available as a part of the SAGA project. This proposal's observations will be the first to compare halo gas kinematics with those of the dwarf satellite populations, which will allow assessments of how much of the absorption seen in more distant halos could arise in satellites. The relative kinematics of stars and gas will also constrain models of halo formation from numerical simulations. Hence, this proposal will open a new window on our understanding of the CGM by combining a large ground-based effort with the unique FUV capabilities of HST/COS. ------------------------------------------------------------------------------------ Observations Description ------------------------ 7 QSOs are to be observed for use as tracers of the CGM around several local MW-like galaxies. 3 of the QSOs have some extended redder galaxies they are embedded in, but all are brighter in the UV, so in COS they should be effectively point-sources. G130M with cenwave 1291 is used to hit most of the low-z CGM lines, with only FP-POS 3/4 being used because several of the critical CGM lines at low-z are on the B segment. ------------------------------------------------------------------------------------ 15826( 3) - 11-Oct-2019 14:49:44 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 FBQSJ095820.
