This Corona shields the LMC from the effects of ram pressure stripping by the Milky Way (MW), but to date, all observations of the Corona have been on the back-side of the LMC CGM. Here we propose 29 orbits of HST/COS G130M/G160M spectroscopic observations of 5 recently-discovered low-latitude (|b|<30 degrees) UV-bright quasars to observe the front-side of the LMC CGM. Aiming to explore both warm-hot and cool phases of the LMC CGM through high and low ion UV metal absorption lines, our goals are to: (1) Detect and characterize the LMC CGM on the uncharted front-side. (2) Compare the LMC CGM between its backand front-sides, providing novel insights into the dynamics of interacting galaxies. (3) Combine these observations with hydrodynamical simulations to constrain the properties of MW CGM, Megellanic CGM, and bow shock region. This research promises to advance our understanding on the ongoing evolution of the interacting galaxies within the Local Group. ------------------------------------------------------------------------------------ Observations Description ------------------------ This is a COS FUV program to observe five QSO targets behind the LMC using G130M and G160M. The science goal is detecting the LMC halo in absorption in a range of UV metal lines. Each target will be acquired with a NUV ACQ/IMAGE with the PSA and MIRRORB, followed by science observations with the G130M/1291 and G160M/1577 settings. For the G160M observations, the four FP-POS positions will be obtained either in one visit or spread across two visits. All visits are up to 3 orbits in length, following the guidance from the PC. ------------------------------------------------------------------------------------ 17757( 5) - 14-Jan-2026 16:33:12 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 PQSJ063403.5 ISM, ABSORPTION LINE RA=06H34M3.5962S +/- 0.1", J2000 Z = V = 16.2 16.37 FUV-mag 9-744637.8 SYSTEM, ABSORPTION LINE DEC=-74D46'37.85" +/- 0.1" 0.112000 SYSTEM - EXTRAGALACTIC, ABSORPTION LINE SYSTEM - GALACTIC, CORONA, CORONAL GAS Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the GALEX database.
