Wave momentum shaping for moving objects in heterogeneous and dynamic media
Bakhtiyar Orazbayev, Matthieu Malléjac, Nicolas Bachelard +2
Light and sound waves have the fascinating property that they can move objects through the transfer of linear or angular momentum. This ability has led to the development of optica…
Testing Connectedness of Images
Piotr Berman, Meiram Murzabulatov, Sofya Raskhodnikova +1
We investigate algorithms for testing whether an image is connected. Given a proximity parameter and query access to a black-and-white image represented by an $n\times…
Model Independent Dark Matter Properties from Cosmic Growth
Tilek Zhumabek, Mikhail Denissenya, Eric V. Linder
Dark matter dominates the matter budget of the universe but its nature is unknown. Deviations from the standard model, where dark matter clusters with the same gravitational streng…
A note on the degree structure of primitive recursive m-reducibility
Birzhan Kalmurzayev, Nikolay Bazhenov, Alibek Iskakov
Let be the upper semilattice of degrees of computable sets with respect to primitive recursive -reducibility. We prove that the first-order theory of is he…
Moving mirrors and event horizons in non-flat background geometry
Evgenii Ievlev
Moving mirrors have been used for a long time as simple models for studying various properties of black hole radiation, such as the thermal spectrum and entanglement entropy. These…
Probing nuclear physics with supernova gravitational waves and machine learning
Ayan Mitra, Daniil Orel, Y. Sultan Abylkairov +2
Core-collapse supernovae are sources of powerful gravitational waves (GWs). We assess the possibility of extracting information about the equation of state (EOS) of high density ma…
Galaxy formation with wave/fuzzy dark matter: The core-halo structure and the solitonic imprint
Alvaro Pozo, Razieh Emami, Philip Mocz +9
Dark matter-dominated cores have long been claimed for the well-studied local group dwarf galaxies. More recently, extended stellar halos have been uncovered around several of thes…
Phenomenological footprints of Lambda varying gravity theories inspired from quantum gravity models in the multi-messenger era
Michael R. R. Good, Vasilios Zarikas
An interesting phenomenological consequence of Lambda varying gravity theories inspired by quantum gravity models is reported. The treatment in the present work is quite general an…
Milky Way globular clusters on cosmological timescales. III. Interaction rates
Maryna Ishchenko, Margaryta Sobolenko, Peter Berczik +4
Aims. We carry out the self-consistent dynamic evolution of the orbital structure of Milky Way globular clusters. This allows us to estimate possible and probable close passages an…
Dust collapse in asymptotic safety: a path to regular black holes
Alfio Bonanno, Daniele Malafarina, Antonio Panassiti
Regular black hole spacetimes are obtained from an effective Lagrangian for Quantum Einstein Gravity. The interior matter is modeled as a dust fluid, which interacts with the geome…
Non-thermal photons and a Fermi-Dirac spectral distribution
Evgenii Ievlev, Michael R. R. Good
Although non-intuitive, an accelerated electron along a particular trajectory can be shown to emit classical electromagnetic radiation in the form of a Fermi-Dirac spectral distrib…
Quasiperiodic oscillations around hairy black holes in Horndeski gravity
Javlon Rayimbaev, Konstantinos F. Dialektopoulos, Furkat Sarikulov +1
Testing gravity theories and their parameters using observations is an important issue in relativistic astrophysics. In this context, we investigate the motion of test particles an…
Variational eigenvalues of the subelliptic -Laplacian
Mukhtar Karazym
We use the Lusternik-Schnirelman theory to prove the existence of a nondecreasing sequence of variational eigenvalues for the subelliptic -Laplacian subject to the Dirichlet bou…

Yingxiu Ma, Jianjun Zhou, Jarken Esimbek +9
We studied the hub filament system G323.46-0.08 based on archival molecular line data from the SEDIGISM 13CO survey and infrared data from the GLIMPSE, MIPS, and Hi-GAL surveys. G3…
Nature of Striation in 21 cm Channel Maps: Velocity Caustics
Yue Hu, A. Lazarian, D. Alina +2
The alignment of striated intensity structures in thin neutral hydrogen (HI) spectroscopic channels with Galactic magnetic fields has been observed. However, the origin and nature…
Subelliptic -Laplacian spectral problem for Hörmander vector fields
Mukhtar Karazym, Durvudkhan Suragan
Based on variational methods, we study the spectral problem for the subelliptic -Laplacian arising from smooth Hörmander vector fields. We derive the smallest eigenvalue, prove…
