X-ray stellar feedback in low-metallicity starbursts: Insights from the template starburst galaxy ESO 338-IG04 and its halo
M. Chatzis, L. M. Oskinova, S. Reyero Serantes +7
The X-ray output of low-metallicity starburst galaxies is a key component of stellar feedback, tracing the processes responsible for gas ionization and chemical enrichment. The int…

First JWST/NIRSpec Spectroscopy of O Stars in the Small Magellanic Cloud
Armin Mang Román, Peter Zeidler, Wolf-Rainer Hamann +10
Determining how much mass is removed by stellar winds is crucial to understanding massive star evolution and feedback. However, traditional spectroscopic diagnostics in the UV and…

Multi-wavelength spectroscopic analysis of the ULX Holmberg II X-1 and its nebula suggests the presence of a heavy black hole accreting from a B-type donor
S. Reyero Serantes, L. Oskinova, W. -R. Hamann +11
Ultra-luminous X-ray sources (ULXs) are high-mass X-ray binaries with an X-ray luminosity above erg s. These ULXs can be powered by black holes that are more massi…
