Does IRS13 require an intermediate-mass black hole?
Václav Pavlík, Vladimír Karas, Florian Peißker +2
We investigate whether the Galactic-centre association IRS13 requires an intermediate-mass black hole (IMBH) to remain bound. Using high-precision -body calculations of IRS13-li…
Constraints on the VHE counterpart of two binary black hole mergers observed by the MAGIC and CTAO LST-1 telescopes
K. Abe, S. Abe, J. Abhir +358
We present very-high-energy gamma-ray observations of two binary black hole merger candidates, GW240615_113620 and GW241125_010116, performed with the Major Atmospheric Gamma Imagi…
Radiation-hydrodynamics of star-disc collisions: From system parameters to outflows and lightcurves
Taj Jankovič, Sergey Karpov, Michal Zajaček +2
Quasi-periodic eruptions (QPEs) are nuclear transients producing bright, repeating soft X-ray flares superimposed on quiescent emission. A promising interpretation is that they are…
Detection of the distant quasar OP 313 with the first Large-Sized Telescope of CTAO
K. Abe, S. Abe, J. Abhir +412
In December 2023, the Large-Sized Telescope prototype (LST-1) detected for the first time VHE -ray emission from the FSRQ OP~313 becoming the furthest blazar ever observed at VH…
Tidal disruption of a low-mass star in an active galactic nucleus as the origin of the PS16dtm outburst
Marzena Śniegowska, Bożena Czerny, Michal Zajaček +7
The event PS16dtm, which occured in the center of the Narrow Line Seyfert 1 (NLS1) galaxy SDSS J015804.75-005221.8 (z = 0.080440), is one of the few candidates for a tidal disrupti…
Formation of stable exoplanetary systems around pulsars by capture: An exercise in computational classical mechanics
Václav Pavlík, Steven N. Shore, Vladimír Karas +1
The study of our Solar System -- its formation, evolution, and long-term stability -- has been ongoing for centuries and is now a standard part of scientific education. While the f…
