Traversing the Galactic Centre in space and time
Michal Zajaček, Bożena Czerny, Martin Mondek +5
The Galactic Center is often identified with its central supermassive black hole, Sgr A*. Yet the black hole governs gravitationally only the innermost few parsecs of the Milky Way…
Constraining the Galactic Center Dark Cluster with ELT/MICADO Observations
Sebastiano D. von Fellenberg, Matúš Labaj, Sean M. Ressler
The Galactic Center hosts the densest known stellar environment in the Milky Way, dominated by the massive black hole Sgr A* and the surrounding nuclear star cluster. Theory predic…
Compact stellar systems hosting an intermediate mass black hole: magnetohydrodynamic study of inflow-outflow dynamics
Matúš Labaj, Sean M. Ressler, Michal Zajaček +3
Intermediate-mass black holes (IMBHs) are a missing link in black hole demographics, with only tentative observational evidence to date. Dense stellar clusters such as IRS 13E near…
Revealing EMRI/IMRI candidates with quasiperiodic ultrafast outflows
Michal Zajaček, Petra Suková, Vladimír Karas +7
The first detection of the quasiperiodic ultrafast outflow in the ASASSN-20qc system was reported by Pasham et al. (2024). The outflow is revealed in the soft X-ray spectra as an a…
Chemically peculiar stars on the pre-main sequence
L. Kueß, E. Paunzen, N. Faltová +12
Context. The chemically peculiar (CP) stars of the upper main sequence are defined by spectral peculiarities that indicate unusual elemental abundance patterns in the presence of d…
Science with a small two-band UV-photometry mission II: Observations of stars and stellar systems
J. Krtička, J. Benáček, J. Budaj +32
We outline the impact of a small two-band UV-photometry satellite mission on the field of stellar physics, magnetospheres of stars, binaries, stellar clusters, interstellar matter,…
