We will do this by obtaining bulk PMs of the three most massive central galaxies of the M81 group at 3.6 Mpc: M81, M82 and NGC 3077. These galaxies are some of the most studied objects in astronomy, with M81 being a canonical grand-design spiral galaxy and M82 the prototype for starburst-driven outflows. These features are driven by an ongoing major merger between these galaxies. We will reimage archival HST fields with a 20-year baseline. Combined with the existing position, distance and radial velocity this will yield 6D position-velocity information. This will allow us to precisely determine the galaxy orbits, shedding light on their past interactions during the ongoing major merger as well as their future trajectories. This will allow us to answer key questions, not only for the M81 Group but also broader universe: (1) how can the observed tidal features be understood dynamically? (2) What is the future of the group, and will either M82 or NGC 3077 be ejected by the three body interaction? (3) What is the mass of the dark matter halos of M81 and M82? (4) What is the transverse velocity of the M81 group, relative to the LG, and how does this compare to our cosmological understanding? The answers will inform simulations and models of galaxy mergers and local flows. We will obtain the first galaxy PMs outside the LG, as well as the first 6D dynamical constraints on an ongoing major merger. These innovations show how HST's longevity allows us to open up new windows on the universe previously considered inaccessible. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will observe 3 target fields of M81 Group using ACS/WFC. All of our target fields have deep ACS/WFC imaging data in the HST archive. In this program, each target field will be observed using the same telescope pointings and 17513( 16) - 02-Jul-2025 20:28:30 - [ 2] orientations as the first-epoch images to maximize the overlaps of the observed fields between first- and second-epoch data. This will also minimize position-dependent uncertainties originating from imperfect CTE and geometric distortion corrections. To measure PMs, it is sufficient to observed only in one filter. We will image all target fields using the F814W filter to measure PMs. For the M82 field, we will also image in F606W filter to construct CMDs that will allow us to separate member stars of target galaxies from foreground contaminants. Individual exposure times will be full-orbit long, and we will use dithered patterns specially designed to maxmimuze pixel-phase coverage. ------------------------------------------------------------------------------------ 17513( 16) - 02-Jul-2025 20:28:30 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 M81 GALAXY, SPIRAL RA=09H54M34.5291S, J2000 V = 6.94 DEC=+69D16'51.65" Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
