Scalarizations of qOS-extremal black hole and Aretakis instability

European Physical Journal C: Particles and Fields
We study scalarization of quantum Oppenheimer–Snyder (qOS)-extremal black hole in the Einstein–Gauss–Bonnet-scalar theory. This black hole is described by mass ( $$M=4\sqrt{\alpha }/3\sqrt{3}$$ M = 4 α / 3 3 ) with $$\alpha $$ α quantum parameter ...

Shadow radius and classical scattering analysis of two secondary hair Horndeski black holes

European Physical Journal C: Particles and Fields
We perform the shadow radius analysis of a charged Horndeski black hole (CHB) and the naked singularity (NS) with secondary scalar hair obtained from the Einstein-Horndeski-Maxwell theory. For this analysis, we include the beyond Horndeski black hole (bH)

Perturbatively exact supersymmetric partition functions of ABJM theory on Seifert manifolds and holography

Journal of High Energy Physics
We undertake a comprehensive analysis of the supersymmetric partition function of the U(N) k × U(N) −k ABJM theory on a U(1) fibration over a Riemann surface, evaluating it to all orders in the 1/N-perturbative expansion up to exponentially suppressed ...

Quantum parameter-mass induced scalarization of qOS-black hole in the Einstein–Gauss–Bonnet-scalar theory

European Physical Journal C: Particles and Fields
We obtain quantum parameter ( $$\alpha $$ α )-mass (M) induced spontaneous scalarization of quantum Oppenheimer–Snyder (qOS)-black hole in the Einstein–Gauss–Bonnet-scalar theory with the unknown qOS action.

Thermodynamic analysis and shadow bound of black holes surrounded by a dark matter halo

European Physical Journal C: Particles and Fields
We perform the thermodynamic analysis of a black hole (BH) immersed in a dark matter halo (DMH). It is shown that the BH could not be in thermal equilibrium with the DMH in any regions outside the event horizon.
