Observations of X-ray quasi-periodic eruptions
Thomas Wevers, Joheen Chakraborty, Erwan Quintin +3
Quasi-periodic eruptions (QPEs) are a novel class of repeating nuclear transients, discovered exclusively in the X-ray band to date. Since their initial discovery in 2019, the QPE…
The Nearest Galactic Nucleus: Studying the Galactic Centre with SKA-Mid
Rainer Schoedel, Antxon Alberdi, Izaskun Jiménez-Serra +24
The paper proposes a large-area, multi‑wavelength continuum survey of the Galactic Centre using SKA‑Mid, covering ~2°×0.4° around Sagittarius A* and repeated deep observations of t…
Evolution of Quasi-Periodic Eruptions in the post-TDE Accretion Disk Perturbed by an Orbiting Star
Martin Mondek, Michal ZajaÄek, Henry Best +3
Quasi-periodic eruptions (QPEs) are a recently discovered class of highly variable X-ray bursts originating in galactic nuclei. These high-amplitude bursts exhibit periodicity rang…
Eclipses of Nearby Millimeter-Bright Galactic Nuclei by Stars in Nuclear Star Clusters
Michal ZajaÄek, Michal Zajaček
It is of a general interest to look for signatures of stellar bodies orbiting supermassive black holes (SMBHs) in galactic nuclei other than the Galactic center. Previously stellar…
High-cadence observations of galactic nuclei by the future two-band UV-photometry mission QUVIK
Michal ZajaÄek, Norbert Werner, Henry Best +12
The Quick Ultra-VIolet Kilonova surveyor (QUVIK), a two-band UV space telescope approved for funding as a Czech national science and technology mission, will focus on detecting ear…
Non-orbital particle trapping in binary black holes through dynamic stability
Ali Kurmus, Michal Zajacek, Greg Kestin +1
We present an interdisciplinary comparison between binary black hole systems and Radio Frequency (RF) Paul Traps, modeling the gravitational binary system as a rotating saddle near…
