In this letter we study thermodynamics of 4D AdS Bardeen Gauss-Bonnet (BGB) black hole. We show it can be involved in the process of the Joule-Thomson expansion. This is done by studying its inversion temperatures. Same as ordinary thermodynamics systems this black hole predicts cooling/heating phase transition if Joule-Thomson coefficient vanishes. Here we investigate effects of the black hole characteristics such as the magnetic charge, the mass and the GB coupling constant variations on the inversion temperature and the phase transition.

“…JT coefficient µ is slope of the T-P isenthalpic curves and so heating (cooling) phase is happened with negative (positive) slope µ < 0(> 0). One can follows [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] where the JT expansion are examined for various types of black holes. The layout of this work is as follows.…”

In this paper, the Joule-Thomson (JT) expansion is investigated for a generalized Ayón-Beato-García (ABG) black hole which is magnetically charged and asymptotically reaches to Anti-de Sitter (AdS) spacetime. This black hole is characterized with five parameters including mass m, magnetic charge q, and three parameters related to nonlinear electrodynamic fields namely α, β, and γ. As an extension of our previous work where we studied thermodynamics and phase transition of this black hole we now investigate JT expansion of it in the present work by plotting the inversion T-P curve and isenthalpic T-P diagrams. Inversion point in T-P phase space separates cooling and heating regimes of the black hole where the black hole parameters play important roles in the position of the inversion point.

“…During the last few decades, there have been a vast number of literature on regular black holes, which includes the study of the thermal phase transition [3][4][5][6][7][8], shadow properties [9][10][11], particle collision and particle accelerations and so on. Recently the connections between the black hole shadow, the quasinormal modes, and the greybody factor have been explored for the electrically charged regular Bardeen black holes [12].…”

In this article, we study the propagation of scalar fields in the gravitational background of a spherically symmetric, electrically charged, regular-de Sitter black holes in higher dimensions. We carry out a thorough investigation of the grey body factors, by deriving analytical expressions for both minimally and non-minimally coupled scalar fields. Then we study the profile of grey body factors in terms of particle properties, namely the angular momentum quantum number and the non-minimal coupling constant, and the spacetime properties, namely the dimension, the cosmological constant and the non-linear charge parameter. We then derive the Hawking radiation spectra for a higher-dimensional electrically charged regular-de Sitter black hole. We find that the non-minimal coupling may suppress the greybody factor and the non-linear charge parameter may enhance it, but they both suppress the energy emission rate of Hawking radiation.
