We present the first Chandra X-ray observations of H72.97–69.39, a highly embedded, potential superstar cluster in its infancy located in the star-forming complex N79 of the Large Magellanic Cloud. We detect particularly hard, diffuse X-ray emission... Read More about Detection of Diffuse Hot Gas around the Young, Potential Superstar Cluster H72.97–69.39.

We present new JWST observations of the nearby, prototypical edge-on, spiral galaxy NGC 891. The northern half of the disk was observed with NIRCam in its F150W and F277W filters. Absorption is clearly visible in the mid-plane of the F150W image, alo... Read More about JWST MIRI and NIRCam observations of NGC 891 and its circumgalactic medium.

The Large Magellanic Cloud (LMC) is home to many H ii regions, which may lead to significant outflows. We examine the LMC’s multiphase gas (T∼104-5 K) in H i, S ii, Si iv, and C iv using 110 stellar sight lines from the Hubble Space Telescope’s Ultra...

Astronomy & Astrophysics, 687, Article A93. https://doi.org/10.1051/0004-6361/202349004

In the Orion Nebula Cluster (ONC), protoplanetary disks exhibit ionized gas clouds in the form of a striking teardrop shape as massive stars irradiate the disk material. We present the first spatially and spectrally resolved observations of 12 such o... Read More about Kaleidoscope of irradiated disks: MUSE observations of proplyds in the Orion Nebula Cluster: I.

Massive star-forming regions are thought to be the most common birth environments in the Galaxy and the only birth places of very massive stars. Their presence in the stellar cluster alters the conditions within the cluster, impacting at the same tim... Read More about The population of young low-mass stars in Trumpler 14.

Pre-supernova stellar feedback in nearby starburst dwarf galaxies (2024)
Journal Article

Context. Stellar feedback in dwarf galaxies remains, to date, poorly explored, yet is crucial to understanding galaxy evolution in the early Universe. In particular, pre-supernova feedback has recently been found to play a significant role in regulat... Read More about Pre-supernova stellar feedback in nearby starburst dwarf galaxies.
