Summary: Motivated by Dynamical Mean Field Theory results, this study examines the two-point function of fermions in an AdS(d+1) charged black brane background in the large d limit. We find the emergence of a locally critical form of the fermion self-energy with a highly constrained range of scaling behaviors at large d. Notable differences from the analysis in d=3,4 include an expanded range of temperatures where the results are applicable and the analytical tractability of the calculations.

Summary: In this article, we study a charged Lifshitz black hole in the limit of large transverse dimensions. We show that the dynamics near the black hole horizon can be effectively described by a family of two-dimensional dilaton gravity models, depending on the ratio between the dynamical parameter of the black hole and the spacetime dimension. This family includes the Callan-Giddings-Harvey-Strominger (CGHS) and Jackiw-Teitelboim (JT) models, as well as their charged equivalents. We also examine a class of asymptotically anti-de Sitter models beyond JT, characterized by a running Ricci scalar and the option to add charge. Finally, we discuss the relationship between non-minimally coupled probe scalars in the parent Lifshitz model and minimally coupled scalars in the two-dimensional theory, which is important for understanding semiclassical corrections in these models.

Summary: In this study, collisions of Gaussian mass-density blobs in a holographic plasma are investigated using a large D effective theory as a model for holographic shockwave collisions. The first 4+1 collisions in Einstein-Maxwell theory, which correspond to collisions of matter with non-zero baryonic number, are successfully simulated using the simplicity of the effective theory. Several collision scenarios with different blob shapes, impact parameters, and charge values are explored, revealing that collisions with impact parameter below the transverse width of the blobs are equivalent under rescaling. The weak effect of charge on other quantities is also observed. The generation of entropy during collisions is studied, considering both charge diffusion and viscous dissipation, and multiple stages of linear entropy growth are identified, with rates dependent on the initial conditions.

Summary: In this study, the phase and stability of black strings in the Einstein-Gauss-Bonnet (EGB) theory were investigated using the large D effective theory approach. The spacetime metric and thermodynamics were derived up to the next-to-leading order (NLO) in the 1/D expansion. It was found that the entropy current defined by the Iyer-Wald formula follows the second law. Similar to the Einstein theory, the entropy difference from the total mass produces an entropy functional for the effective theory. Including the NLO correction, it was discovered that the Gregory-Laflamme instability of uniform black strings requires longer wavelengths for large Gauss-Bonnet coupling constant alpha(GB). Moreover, it was shown that the critical dimension, beyond which non-uniform black strings become more stable than uniform ones, increases as alpha(GB) becomes large, and approaches a finite value for alpha(GB)-> infinity.

Summary: We investigate the scattering of gravitational waves by a Schwarzschild black hole and its perturbed siblings to examine the effect of proposed spectral instability of quasinormal modes on the ringdown signal. Our findings show that the information of dominant ringdown signals, associated with the least damping quasinormal mode of unperturbed Schwarzschild black holes, is imprinted in the phase shift of the transmission amplitude. This behavior is analogous to the resonance of quantum systems being imprinted in the phase shift of the S matrix. The phase shift near the oscillation frequency of the fundamental mode is only perturbatively modified, indicating the stability of the ringdown signal, while the phase shift at low frequencies is significantly modulated due to the late-time excitation of echo signals associated with the destabilized quasinormal-mode spectrum.

Summary: Various astrophysical methods are used to detect possible deviations from General Relativity in this work. A class of f(R) gravity models, selected by the existence of Noether symmetries, is considered. The study determines static and spherically symmetric black hole solutions that encompass small departures from the Schwarzschild geometry. The proposed strategy of using ray-tracing technique and considering the Poynting-Robertson effect proves to be robust and efficient in investigating gravity and detecting small deviations from General Relativity.

Summary: This paper investigates the number of horizons of static black holes and finds that it is strongly constrained by the energy conditions of matter fields. The study reveals universal restrictions on the number of horizons, indicating that the presence of matter not only promotes the formation of event horizons but also prevents the appearance of multiple horizons inside black holes.

Summary: The criterion for thermodynamic stability of rotating electrically charged quantum black holes was derived and analyzed in this paper. The quasi-stable black holes were shown to have bounded fluctuations in certain regions of their parameter space, and transformations to different kinds of black holes were observed during their Hawking decay.

Summary: We investigate the phase space of non-uniform black branes on oblique lattices with numerous dimensions. We discover the phase diagrams for various periodicities and angles, and identify the thermodynamically favored phases for each lattice configuration. In a specific range of angles, we observe the metastability of certain phases.

Summary: In this paper, the notion of hidden conformal symmetry in Kerr-(A)dS black holes is generalized, and a relationship between SL(2, R) generators and Killing tensors is established to enforce the separability of equations of motion. Additionally, explicit forms for zero mode symmetry generators are found by evaluating the Klein-Gordon scalar wave equation.

Summary: This study investigates black strings/funnels and other black hole configurations in AdS that correspond to different phases of the dual CFT in black hole backgrounds, using different approaches at large D. The phase diagram of uniform and non-uniform black strings/funnels is assembled, and their dynamical stability is examined. Flowing horizons are also constructed. Many of the results are available analytically, although some are known only numerically.

Summary: We investigate the weak cosmic censorship conjecture in Myers-Perry black holes in general dimensions using the scattering of a massless scalar field. By analyzing the fluxes of the scalar field into the black hole and the changes in mass and angular momenta of the black hole, we find that the conjecture holds true. Moreover, the changes in the black hole are also examined from a thermodynamic perspective, which further supports the conjecture.

Summary: In this study, a novel analytic technique for constructing new analytic solutions of black strings is proposed, assuming that the Gauss-Bonnet term dominates over the Einstein-Hilbert term. The results obtained using this technique are consistent with numerical calculations, confirming the accuracy of the analytic solutions.

Summary: In this study, we calculate the quasinormal modes of spin 0, 1/2, 1, 3/2, 2, and 5/2 fields in the asymptotically flat Schwarzschild black hole spacetime using numerical methods. We compare the results with the available literature and test different numerical methods. Additionally, we obtain purely imaginary frequencies for spin 1/2, 3/2, and 5/2 fields, which are consistent with previous analytic results.

Summary: We study holographically nonlocal observables in field theories at finite temperature and in the large d limit. The large d limit simplifies the analysis for nonlocal observables and retains their qualitative physical properties. We also study the monotonicity of the coefficient alpha of the entanglement's area term and find its convergence at large d. The expectation values of the observables show rapid convergence as d increases and the extrapolation of the large d limit agrees well with numerical analysis.

Summary: This study examines the solutions of stationary black rings in Einstein-Maxwell theory with or without cosmological constant within the framework of the large D membrane paradigm. It is shown that the first order membrane equations only allow for static asymptotically flat black rings, and the equilibrium angular velocity for asymptotically AdS black rings at large D is obtained. The thermodynamic and dynamic stability of the asymptotically flat black ring solutions is also investigated, with arguments that the apparent shortcomings of some results can be addressed within the large D membrane paradigm framework.

Summary: This study constructs static solutions of non-extremal and squashed black holes using the large D effective theory approach, describing spherical black holes in a Kaluza-Klein spacetime with a compactified dimension. The asymptotic background and near-horizon geometry with a compactified dimension are analytically solved by the 1/D expansion. Additionally, the large D limit is shown to be applicable in solving non-trivial backgrounds with a compactified direction, leading to a first-order flow equation, and the extremal limit reproducibly produces known results.

Summary: The study examines the contributions of higher order images (HOIs) to the relativistic Fe K-alpha line profile near a Kerr black hole, finding that these features imprint characteristic effects on the line profile depending on black hole spin, disc emissivity laws, and inclinations. Simulations of future observations show that failing to account for HOI contributions to the Fe K-alpha line profile may bias measurements of the black hole spin parameter towards higher values by up to around 0.3.

Summary: This study on the stability of quasinormal modes in asymptotically flat black hole spacetimes utilizes a pseudospectrum analysis to reveal the stability and instability under different perturbations. The analysis sheds light on the infrared effects and ultraviolet perturbations affecting the overtones of QNM, with potential implications for gravitational-wave physics and fundamental spacetime fluctuations.
