On the development of quasi-periodic oscillations in Bondi–Hoyle accretion flows
, 2010 The numerical investigation of Bondi-Hoyle accretion onto a moving black hole has a long history, both in Newtonian and in general-relativistic physics. By performing new two-dimensional and general-relativistic simulations onto a rotating black hole, we point out a novel feature, namely, that quasi-periodic oscillations (QPOs) are naturally produced ...

Bridging Scales in Black Hole Accretion and Feedback: Subgrid Prescription from First Principles
The Astrophysical Journal LettersUnderstanding how supermassive black holes (BHs) couple to their host galaxies across a vast spatial and temporal dynamic range remains a central challenge in galaxy evolution.

Conflict Resolution Quarterly, Volume 43, Issue 2, Page 313-322, Winter 2025.ABSTRACT This paper examines the ontological complexity of public space through an analysis of the long‐running dispute over the development of Redlowska Glade, a green area in Gdynia, Poland. Drawing on relational ontology perspective, the study explores how conflicting parties not only debated the future of this space but also enacted different ...

Numerical simulations of rotating bondi accretion flows
, 2015 We explore through numerical simulations the structure formed around a black hole as a consequence of supersonic Bondi accretion with a small, finite angular momentum. The structure accompanies an accretion shock, inside which the flow is subsonic and is

Self-limited Accretion onto Embedded Binaries in a Uniform Medium
The Astrophysical JournalWe study accretion from a uniform gas at rest onto equal-mass binaries—the binary Bondi problem—as a function of the adiabatic index γ and compactness ξ ≡ R _B / a , where R _B is the Bondi radius of the binary and a is the component separation.

Journal of Fish Biology, Volume 107, Issue 6, Page 2166-2172, December 2025.Abstract We formally describe the association of fishes and anthozoans in epipelagic waters, extending this relationship to beyond the benthos. In situ observations and photographs of Aluterus schoepfii, Ariomma regulus, Caranx cf. latus and Brama spp.

, 2006 Our X-ray study of the nuclear activity in a new sample of six quiescent early-type galaxies, as well as in a larger sample from the literature, confirmed (Paper I) that the Bondi accretion rate of diffuse hot gas is not a good indicator of the SMBH X ...

Residual distribution schemes for Bondi‐Hoyle accretion [PDF]
PAMM, 2007 AbstractBlack hole accretion is a key component in astrophysical phenomena such as gamma‐ray bursts and quasars. As a step towards understanding such phenomena, accurate and efficient computational methods for simulating gas dynamics in the presence of black holes must be developed.

The Astrophysical JournalStars and compact objects embedded in accretion disks of active galactic nuclei (AGNs), dubbed accretion-modified stars (AMSs), often experience hyper-Eddington accretion in the dense gas environment, resulting in powerful outflows as the Bondi explosion
