Thermodynamic acceptability of spherically symmetric perfect-fluid solutions in general relativity
Dina Demissenova, Nurzada Beissen, Kuantay Boshkayev +1
The paper extends the usual physical acceptability criteria for static, spherically symmetric perfect‑fluid solutions of Einstein’s equations by adding thermodynamic conditions bas…
A Possible Triple Formation Scenario of Binary Black Hole Merge With One In Pair-instability Supernova Mass Gap
Tian Huang, Xizhen Lu, Guoliang Lü +8
Observations of binary black hole (BBH) mergers detected by LIGO -- such as GW170729, GW190620, GW190706, GW230107, GW230820, and GW230928 -- feature high effective spins and prima…
Wormholes in Einstein-Dirac-Maxwell theory with identical spacetime asymptotics
Vladimir Dzhunushaliev, Vladimir Folomeev, Nurzada Beissen +1
Within general relativity, we study spherically symmetric configurations with wormhole topology consisting of spinor fields and a Maxwell electric field. For such a system, we cons…
Formation of the Dormant Black Holes with Luminous Companions from Binary or Triple Systems
Zhuowen Li, Xizhen Lu, Guoliang Lü +6
Recently, a class of dormant black hole binaries with luminous companions (dBH-LC) has been observed, such as BH1, BH2, and BH3. Unlike previously discovered X-ray BH binari…
