Impacts of urbanization and tourism on the erosion and accretion of European, Asian and African coastal areas and possible solutions [PDF]
Urbanism. Arhitectura. Constructii, 2020 Coastal areas are very important due to the ecosystem services provided to the inhabitants. However, these advantages have resulted into an increasing attraction, especially in the recent centuries.

Galaxies, 2023 We study radio and X-ray emissions from intermediate-mass black holes (IMBHs) and explore the unified model for accretion and ejection processes. The radio band survey of IMBH (candidate) hosted galaxies indicates that only a small fraction (∼0.6%) of ...

A global view of the inner accretion and ejection flow around super massive black holes [PDF]
Astronomy & Astrophysics, 2019 Context. Understanding the physics and geometry of accretion and ejection around super massive black holes (SMBHs) is important to understand the evolution of active galactic nuclei (AGN) and therefore of the large scale structures of the Universe. Aims.

Геодинамика и тектонофизика, 2021 The formation of continental crust in the Mongolia-Transbaikalia region is researched to identify the mechanisms of interactions between the crust and the mantle in the development of the Neoarchean, Proterozoic and Paleozoic magmatic and sedimentary ...

TERRAIN TECTONICS OF THE CENTRAL ASIAN FOLDED BELT
Геодинамика и тектонофизика, 2015 The terrain analysis concept envisages primarily a possibility of approximation of fragments / terrains of various geodynamic settings which belong to different plates. The terrain analysis can supplement the theory of plate tectonics in solving problems

The high energy X-ray probe (HEX-P): studying extreme accretion with ultraluminous X-ray sources
Frontiers in Astronomy and Space Sciences, 2023 Introduction: Ultraluminous X-ray sources (ULXs) represent an extreme class of accreting compact objects: from the identification of some of the accretors as neutron stars to the detection of powerful winds travelling at 0.1–0.2 c, the increasing ...

Hydrodynamics of Circumbinary Accretion: Angular Momentum Transfer and Binary Orbital Evolution [PDF]
Astrophysical Journal, 2018 We carry out 2D viscous hydrodynamical simulations of circumbinary accretion using the moving-mesh code AREPO. We self-consistently compute the accretion flow over a wide range of spatial scales, from the circumbinary disk (CBD) far from the central ...

, 2015 The Central Asian Orogenic Belt records the accretion and convergence of three collage systems that were finally rotated into two major oroclines. The Mongolia collage system was a long, N–S-oriented composite ribbon that was rotated to its current ...

Universe, 2021 Double-spiral galaxies are common in the Universe. It is known that the logarithmic double spiral is a Maximum Entropy geometry in hyperbolic (flat) spacetime that well represents an idealised spiral galaxy, with its central supermassive black hole (SMBH)

Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. IX. 10 New Observations of Reverberation Mapping and Shortened Hβ Lags [PDF]
, 2018 As one paper in a series reporting on a large reverberation mapping campaign of super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs), we present the results of 10 SEAMBHs monitored spectroscopically during 2015–2017 ...
