Receipt: # 6599-3 ----- Attempting Submission 4 (Thu Apr 10 21:37:37 GMT 2025) ----- We propose to conduct a deep, archival census of dust in the Tarantula Nebula (also known as 30 Doradus/Dor), the most luminous star-forming region in the Local Group. Located in the Large Magellanic Cloud (LMC), the Tarantula (also known as 30 Doradus/Dor), is suffused with active star formation and is near enough (~50 kpc) for individual stars and clouds to be fully resolved. These conditions make 30 Dor the ideal laboratory for studying the formation and evolution of starbursts in galaxies. Leveraging archival Hubble Space Telescope imaging from the Hubble Tarantula Treasury Program (HTTP), we will constrain the intrinsic properties of resolved stars and dust simultaneously. Our goal is to produce a new, high-resolution (~pc-scale) map of the total dust extinction in 30 Dor, independent of standard emission tracers, to resolve the structure and properties of the dusty ISM and how it is shaped by this enigmatic starburst. Team: Claire Murray, Yumi Choi, Karl Gordon, Karin Sandstrom, Ben Williams, Julia Roman-Duval, Caroline Bot, Karoline Gilbert, L. Cliff Johnson, Roger Cohen, Petia Yanchulova Merica-Jones, Martha Boyer, Alec Hirschauer, Kristen McQuinn, Christina Lindberg, Steve Goldman, Christopher Clark, Joshua Peek, Elizabeth Tarantino, Tony Wong, Remy Indebetouw, Elena Sabbi, Catherine Zucker PI Murray is an expert in the multiphase interstellar medium traced by radio spectral lines and resolved stellar populations. As the PI of Scylla, a 500-orbit HST imaging program (PIDs 15891, 16235, 16786) in parallel with ULLYSES to survey dust in the Magellanic Clouds, Murray has extensive experience with planning, executing and analyzing multi-wavelength resolved stellar photometry from HST. PI Murray will lead the scientific analysis. Co-I WIlliams will lead the data reduction effort, including photometry and artificial star tests required for quantifying uncertainty, completeness and bias. Co-I Williams has a full decade of experience with these tasks for virtually all multi-wavelength HST surveys of resolved stellar populations in the Local Group, including PHAT, PHATTER, SMIDGE, METAL and Scylla (PIDs 12581, 13659, 14675, 15891, 16235, 16786). The team includes experts on the gas (Murray, Roman-Duval, Peek, Tarantino, Wong, Indebetouw), dust (Gordon, Sandstrom, Bot, Johnson, Hirschauer, Clark, Goldman), ISM structure (Zucker, Yanchulova Merica-Jones, Lindberg), and stellar populations (Choi, Gilbert, Williams, Boyer, Cohen, McQuinn, Sabbi) of galaxies in the Local Group. This includes science analysis (star formation histories, rare stellar types, star formation feedback, dust production and destruction) as well as technical execution of HST observations.
