Journal Article
Gull, M., Weisz, D. R., Senchyna, P., Sandford, N. R., Choi, Y., McLeod, A. F., …Williams, B. F. (2022). A Panchromatic Study of Massive Stars in the Extremely Metal-poor Local Group Dwarf Galaxy Leo A*. Astrophysical Journal, 941(2), Article 206. https://doi.org/10.3847/1538-4357/aca295

We characterize massive stars (M > 8 M⊙) in the nearby (D ∼ 0.8 Mpc) extremely metal-poor (Z ∼ 5% Z⊙) galaxy Leo A using Hubble Space Telescope ultraviolet (UV), optical, and near-infrared (NIR) imaging along with Keck/Low-Resolution Imaging Spectrog...

Journal Article
Della Bruna, L., Adamo, A., McLeod, A. F., Smith, L. J., Savard, G., Robert, C., Sun, J., Amram, P., Bik, A., Blair, W. P., Long, K. S., Renaud, F., Walterbos, R., & Usher, C. (2022). Stellar feedback in M 83 as observed with MUSE II. Analysis of the H II region population: Ionisation budget and pre-SN feedback. Astronomy & Astrophysics, 666, Article A29. https://doi.org/10.1051/0004-6361/202243395

Context. Energy and momentum injected by young, massive stars into the surrounding gas play an important role in regulating further star formation and in determining the galaxy’s global properties. Before supernovae begin to explode, stellar feedback... Read More about Stellar feedback in M 83 as observed with MUSE II.

Linking stellar populations to H II regions across nearby galaxies (2022)
Journal Article
Barnes, A., Chandar, R., Kreckel, K., Glover, S., Scheuermann, F., Belfiore, F., Bigiel, F., Blanc, G., Boquien, M., den Brok, J., Congiu, E., Chevance, M., Dale, D., Deger, S., Kruijssen, J., Egorov, O., Eibensteiner, C., Emsellem, E., Grasha, K., Groves, B., …Williams, T. (2022). Linking stellar populations to H II regions across nearby galaxies. Astronomy & Astrophysics, 662, https://doi.org/10.1051/0004-6361/202243766

Context. Stellar feedback is one of the fundamental factors regulating the evolution of galaxies. However, we still do not have access to strong observational constraints on the relative importance of the different feedback mechanisms (e.g. radiation...

Supernova Remnants in M83 as Observed with MUSE (2022)
Journal Article
Long, K. S., Blair, W. P., Winkler, P. F., Della Bruna, L., Adamo, A., McLeod, A. F., & Amram, P. (2022). Supernova Remnants in M83 as Observed with MUSE. Astrophysical Journal, 929(2), Article 144. https://doi.org/10.3847/1538-4357/ac5aa3

Here we describe a new study of the supernova remnants (SNRs) and SNR candidates in nearby face-on spiral galaxy M83, based primarily on MUSE integral field spectroscopy. Our revised catalog of SNR candidates in M83 has 366 objects, 81 of which are r... Read More about Supernova Remnants in M83 as Observed with MUSE.

Stellar feedback in M83 as observed with MUSE: I. Overview, an unprecedented view of the stellar and gas kinematics and evidence of outflowing gas (2022)
Journal Article
Della Bruna, L., Adamo, A., Amram, P., Rosolowsky, E., Usher, C., Sirressi, M., Schruba, A., Emsellem, E., Leroy, A., Bik, A., Blair, W. P., McLeod, A. F., Östlin, G., Renaud, F., Robert, C., Rousseau-Nepton, L., & Smith, L. J. (2022). Stellar feedback in M83 as observed with MUSE: I. Overview, an unprecedented view of the stellar and gas kinematics and evidence of outflowing gas. Astronomy & Astrophysics, 660, Article A77. https://doi.org/10.1051/0004-6361/202142315

Context. Young massive stars inject energy and momentum into the surrounding gas, creating a multi-phase interstellar medium (ISM) and regulating further star formation. The main challenge of studying stellar feedback proves to be the variety of scal... Read More about Stellar feedback in M83 as observed with MUSE: I.
