Surveying Star Cluster Outflows in NGC 4449 ------------------------------------------------------------------------------------ Type Cycle GO 33 ------------------------------------------------------------------------------------ Investigators Contact?

Supernovae and stellar winds that are correlated in space and time thermalize their energy to produce hot, expanding bubbles of T ~ 10^7 K gas. When these bubbles merge with others, they can break out of the disk, powering galactic fountains and winds. In starburst galaxies, the star cluster population collaborates to drive kiloparsec-scale outflows. However, how this collaboration occurs remains unclear. It is not known whether galactic winds are driven predominantly by a small number of high-mass clusters (log(M/M_sun) >= 4.5) or by the combined contributions of many lower mass clusters (3 < log(M/M_sun) < 4.5). We propose to answer this question in the nearby dwarf starburst galaxy NGC 4449 (d = 4 Mpc), where we will survey the warm ionized outflows associated with 12 star clusters (11 new and one archival) with 3.4 =< log(M/M_sun) =< 5.4 using "down-the-barrel" COS/G130M spectroscopy. We will measure the metal column densities, traced by N(Si) = N(SiII) + N(SiIII) + N(SiIV), as a function of velocity to constrain the energy and metal mass engaged in galactic fountains (v < v_esc) and winds (v > v_esc) as a function of cluster mass. By quantifying the role of lower mass clusters in driving starburst winds, we will determine the dominant drivers of the large-scale outflows that heat and chemically enrich the circumgalactic and intergalactic medium. ------------------------------------------------------------------------------------ Observations Description ------------------------ We propose a COS FUV survey of warm outflows from 11 young, massive star clusters across the nearby dwarf starburst galaxy NGC 4449 (D = 4 Mpc). The program goal is to determine the feedback contribution, or the amount of outflowing gas in winds (v > v_esc) or fountains (v < v_esc), as a function of cluster mass. We will detect the outflowing gas in absorption from low and intermediate ions against the light of the UV-bright clusters. For each cluster, we will measure the metal column densities associated with warm, diffuse outflows, as traced by the Si column density, N(Si) = N(SiII) + N(SiIII) + N(SiIV). We will use COS/G130M with cenwav = 1291 A to cover the SiII (1190, 1193, 1304 A), SiIII (1206 A), and SiIV (1393, 1402 A) transitions. The exposure time is divided evenly between FP-POS = 3 and 4 to improve the S/N. The medium resolution grating (FWHM = 14 - 19 km/s) is needed to resolve the gas 18015( 2) - 14-Aug-2025 20:04:04 - [ 2] kinematics and determine the column density at v > v_esc. To determine the exposure times, we measured the flux within the COS aperture in an archival HST/WFC3 F218W image (Program 16316, PI Sabbi) and extrapolated to the COS band with the ETC assuming a typical cluster spectral energy distribution and the total (foreground and intrinsic) E(B - V) from Bradley et al. (2020). We validated our exposure time calculation by applying the same procedure to an archival COS spectrum of a star cluster in NGC 4449. We require S/N = 10 at SiIV 1393, 1402 to measure the column density and the velocities to the required precision. This criterion ensures S/N > 10 at SiII and SiIII. This yields total exposure times of t_exp = 1000 - 15500 s, or 1 - 8 orbits per sightline for a total request of 30 orbits. All targets are faint and point-like, and thus a standard target acquisition in ACQ/IMAGE mode is most efficient. The target coordinates are well-known and have been validated using multi-band archival HST/WFC3 imaging of NGC 4449. The ETC and BOT reported no warnings for violations of the bright object limits. ------------------------------------------------------------------------------------ 18015( 2) - 14-Aug-2025 20:04:04 -
