Open AccessCharged and magnetized particle motion around a static black hole in the Starobinsky–Bel–Robinson gravity
In this work we focus on the effects of Starobinsky–Bel–Robinson (SBR) gravity parameter and external magnetic field on the motion of charged test particles and magnetic dipoles moving around a black hole in t...

Open AccessCircular orbits and accretion disk around AdS black holes surrounded by dark fluid with Chaplygin-like equation of state
In the present work we study the geodesic motion and accretion process of a test particle near an Anti-de Sitter (ADS) BH surrounded by a dark fluid with a Chaplygin-like equation. Within the defined paradigm,...

Open AccessMachine-learning-based particle identification with missing data
In this work, we introduce a novel method for Particle Identification (PID) within the scope of the ALICE experiment at the Large Hadron Collider at CERN. Identifying products of ultrarelativisitc collisions d...

Open AccessUniversal relations for compact stars with exotic degrees of freedom
The nature of the highly dense matter inside the supernova remnant compact star is not constrained by terrestrial experiments and hence modeled phenomenologically to accommodate the astrophysical observations ...

Open AccessTesting strong gravitational lensing effects of various supermassive compact objects for the static and spherically symmetric hairy black hole by gravitational decoupling
We investigate the strong gravitational lensing effects of various supermassive compact objects for the static and spherically symmetric hairy black hole by gravitational decoupling. To do this purpose, we fir...

Open AccessX-ray emission spectrum for axion–photon conversion in magnetospheres of strongly magnetized neutron stars
Detecting axionic dark matter (DM) could be possible in an X-ray spectrum from strongly magnetized neutron stars (NSs). We examine the possibility of axion–photon conversion in the magnetospheres of strongly m...

Open AccessStatic and spherically symmetric vacuum spacetimes with non-expanding principal null directions in f(R) gravity
In this work we characterize all the static and spherically symmetric vacuum solutions in f(R) gravity when the principal null directions of the Weyl tensor are non-expanding. In contrast to General Relativity, w...

Open AccessNotes on wormhole cancellation and factorization
In AdS/CFT, partition functions of decoupled CFTs living on separate asymptotic boundaries factorize. However, the presence of bulk wormholes connecting different boundaries tends to spoil the factorization of...
