Could globular clusters in the vicinity of the galactic centre have contributed stars to the nuclear star cluster in the past?
Kalambay M., Kuvatova D., Ishchenko M. +3
The results of direct N-body simulations of three Milky Way bulge globular clusters - Terzan 2, Terzan 4, and Terzan 5 - evolving in a time-varying galactic potential derived from…
Hydrostatic pressure effect on the pseudogap in Y0.77Pr0.23Ba2Cu3O7-δsingle crystals
A. L. Solovjov, L. V. Bludova, A. S. Kolesnik +6
We studied the changes of resistivity , superconducting transition temperature , fluctuation conductivity , and pseudogap of …
The contribution to Galactic Centre γ-ray excess from cluster-born millisecond pulsars. Constraints from direct N-body simulations
M. Kalambay, M. Ishchenko, D. Kuvatova +2
The Galactic Centre γ-ray excess (GCE), observed by Fermi-LAT around Sgr A*, exceeds expectations from standard cosmic-ray models and is commonly attributed either to dark matter a…
Evolution of fractality in centrally concentrated young clusters
Almat Akhmetali, Adilkhan Assilkhan, Mordecai-Mark Mac Low +6
We investigate the structural evolution of young star clusters forming within centrally concentrated molecular clouds. Our simulations use the Torch framework, which integrates the…
Study of fluctuation conductivity in YBaCuO-- films in strong magnetic fields
E. V. Petrenko, L. V. Omelchenko, Yu. A. Kolesnichenko +4
We report the effect of the \emph{ab}-plane magnetic field up to on the resistivity and fluctuation conductivity in YBaCuO thin f…
Thermal properties of Klein-Gordon Oscillator in the Context of Amelino-Camelia and Magueijo-Smolin Doubly Special Relativity (DSR) frameworks
Abdelmalek Boumali, Nosratollah Jafari, Bekdaulet Shukirgaliyev +1
We examine the thermal and statistical properties of the one dimensional Klein-Gordon oscillator within two prominent Doubly Special Relativity (DSR) frameworks: Amelino-Camelia an…
Dynamical model of Praesepe and its tidal tails
L. Weis, C. West, A. Just +5
Context. The dynamical evolution of open clusters in the tidal field of the Milky Way and the feeding of the disc field star population depend strongly on the initial conditions at…
Evolution of star clusters with initial bulk rotation via N-body simulations
Abylay Bissekenov, Xiaoying Pang, Albrecht Kamlah +6
Young star clusters can inherit bulk rotation from the molecular clouds from which they have formed. This rotation can affect the long-term evolution of a star cluster and its cons…
Centrally concentrated star formation in young clusters
Adilkhan Assilkhan, Mordecai-Mark Mac Low, Brooke Polak +6
The study of star cluster evolution necessitates modeling how their density profiles develop from their natal gas distribution. Observational evidence indicates that many star clus…
Dynamical evolution of the open clusters with different star formation efficiencies and orbital parameters
M. Ishchenko, V. Masliukh, M. Hradov +3
Open star clusters are dynamic systems whose evolution is critically influenced by initial conditions such as star formation efficiency and orbital parameters. Understanding their…
Dynamical evolution of Milky Way globular clusters on the cosmological timescale I. Mass loss and interaction with the nuclear star cluster
M. Ishchenko, P. Berczik, T. Panamarev +7
Context. Based on the Gaia DR3, we reconstructed the orbital evolution of the known Milky Way globular clusters and found that six objects, NGC 6681, NGC 6981, Palomar 6, NGC 6642,…
Temperature dependence of upper critical fields and coherence lengths for optimally-doped thin films
E. V. Petrenko, L. V. Omelchenko, A. V. Terekhov +4
We report the comprehensive comparative analysis of the upper critical magnetic fields obtained within Ginzburg-Landau and Werthamer-Helfand-Hohenberg theories for…
Influence of electron irradiation on fluctuation conductivity and pseudogap in single crystals
A. L. Solovjov, L. V. Omelchenko, E. V. Petrenko +4
The effect of electron irradiation with the energy of 2.5 MeV on the temperature dependences of the resistivity of an optimally doped single crystal has been stu…
Modulo periodic Poisson stable solutions of quasilinear differential equations
Marat Akhmet, Madina Tleubergenova, Akylbek Zhamanshin
We introduce a new type of recurrence in the space of continuous and bounded functions. The property is easily verifiable, and can be considered for differential equations. This ti…
Unpredictable Solutions of Linear Differential Equations
Marat Akhmet, Mehmet Onur Fen, Madina Tleubergenova +1
In this study, the existence and uniqueness of the unpredictable solution for a non-homogeneous linear system of ordinary differential equations is considered. The hyperbolic case…
