JWST reveals a highly ionized nebula powered by an ultraluminous X-ray source with a massive black hole in the metal-poor galaxy Holmberg II

F. A. Fogantini, P. Zeidler, L. M. Oskinova +9

Recent James Webb Space Telescope (JWST) observations have revealed fine-structure lines of ions with ionization potentials \,eV, such as [Ne\,{\sc v}] and [O\,{\sc iv…

First spectroscopic identification of the main sequence in Westerlund 1

R. Castellanos, F. Najarro, M. Garcia +8

Being the most massive known young stellar cluster in the Milky Way, Westerlund 1 (Wd1) constitutes an ideal benchmark for understanding the evolution of massive stars. However, th…

Investigating silicate, carbon, and water in the diffuse interstellar medium: the first shots from WISCI

S. T. Zeegers, Jonathan P. Marshall, Karl D. Gordon +33

The dusty interstellar medium (ISM) of the Milky Way is distributed in a complex, cloudy structure. It is fundamental to the radiation balance within the Milky Way, provides a reac…

Updated radial velocities and new constraints on the nature of the unseen source in NGC1850 BH1

Sara Saracino, Tomer Shenar, Sebastian Kamann +7

A black hole candidate orbiting a luminous star in the Large Magellanic Cloud young cluster NGC 1850 (Myr) has recently been reported based on radial velocity and light cu…

The Galactic WC and WO stars: The impact of revised distances from Gaia DR2 and their role as massive black hole progenitors

Andreas A. C. Sander, Wolf-Rainer Hamann, Helge Todt +4

Wolf-Rayet stars of the carbon sequence (WC stars) are an important cornerstone in the late evolution of massive stars before their core collapse. As core-helium burning, hydrogen-…

Stellar population of the superbubble N206 in the LMC II. Parameters of the OB and WR stars, and the total massive star feedback

Varsha Ramachandran, W. -R. Hamann, R. Hainich +5

Clusters or associations of early-type stars are often associated with a 'superbubble' of hot gas. The formation of such superbubbles is caused by the feedback from massive stars.…
