Summary: The study demonstrates the avoidance of the no-hair theorem in scalar-tensor theories with bimetric structure by introducing an electric charge, leading to black hole solutions with rich thermodynamic behavior. The interplay of stability and phase transitions between different black hole configurations resembles a solid-liquid-gas system, with an electric potential acting as pressure and a triple point where three phases coexist equally probable.

Summary: The MOG theory modifies gravity by introducing dynamical scalar fields and a massive vector field, explaining cosmological phenomena, galaxy rotation curves, and solar system observations successfully. It associates matter with a fifth force and a modified equation of motion, eliminating the need for dark matter.

Summary: The study focuses on static and spherically symmetric charged stars with a nontrivial profile of the scalar field in Einstein-Maxwell-scalar theories, showing that this type of interaction can induce spontaneous scalarization under certain conditions. The analysis indicates that spontaneous scalarization of stars can be induced not only by the coupling to curvature invariants but also by the scalar-gauge coupling in Einstein gravity.

Summary: In a scalar-vector-tensor theory, the stability of static spherically symmetric black holes under linear odd-parity perturbations is studied. The action is calculated to second order in the linear perturbations to obtain a master equation for these perturbations. No-ghost and Laplacian instability conditions are derived for this general class of models. The stability conditions for particular cases are examined using the generalized Regge-Wheeler potential.

Despite local differences from the traditional metric, the solutions can be recovered to the standard metric by imposing suitable asymptotic conditions.

Summary: The study investigates the radial stability of scalarized black-hole solutions and shows that Ricci coupling has a positive impact on their stability. In addition, it is found that Ricci coupling significantly reduces the region where hyperbolicity is lost in the equation governing linear, radial perturbations.

Summary: The article investigates the phase diagram of solutions of the charged black hole bomb system, particularly focusing on static hairy black holes in the Einstein-Maxwell-Scalar theory. These hairy black holes have higher entropy and may serve as the endpoint of instabilities in the black hole bomb system, relating to boson stars in the theory.

Summary: We construct a cohomogeneity-1 helical black string in six-dimensional Einstein gravity originating from the superradiant instability of the Myers-Perry black string. The helical black string possesses helical isometries generated by linear combinations of time translation, shifts along the string, and rotation, which are individually broken by the superradiant instability. Despite the absence of momentum in the string direction, the helical black string exhibits nonzero horizon velocity.

Summary: This paper investigates the effects of quantum corrections of the Einstein-Maxwell theory on the first law of black hole thermodynamics. The results suggest that the first law might still hold in the effective region, even with the inclusion of higher-curvature terms and nonminimally coupled electromagnetic fields.

Summary: In this study, we investigate planar hairy black hole configurations in higher dimensions for a special subclass of the Horndeski theory. This theory is defined by two coupling functions depending on the kinetic term and enjoying shift symmetry and reflection symmetry. We obtain a set of new solutions and calculate their thermodynamic quantities, showing that for a suitable choice of the coupling functions, the shear viscosity violates the Kovtun-Son-Starinets bound.

Summary: This study investigates the time evolutions of charged scalar perturbations on the background of a charged hairy black hole. By analyzing the quasinormal modes extracted from the waveform of scalar perturbations, it is discovered that some quasinormal modes can be superradiantly amplified when trapped in a potential well between two potential peaks. These superradiant modes render the charged hairy black hole unstable against charged scalar perturbations.

Summary: This paper argues that expanding bubbles of nothing are a common feature in systems of black holes with multiple or non-spherical horizons. The authors provide explicit constructions in four and five dimensions to demonstrate this idea, showing that the geometries of expanding bubbles arise as a limit of static black hole binaries and black rings. They also discuss the possibility of similar constructions in higher dimensions, although numerical methods are often required. The paper concludes by suggesting that the Nariai solution can be understood as containing an expanding circular bubble of nothing.

Summary: This study investigates the waveforms of time signals produced by scalar perturbations in static hairy black holes. The waveforms are influenced by a double-peak effective potential. When the distance between the peaks is large, a series of decaying echo pulses are generated. However, when the peaks are close, fewer echo signals and a slowly decaying sinusoid tail are observed.

Summary: The propagation of high-frequency gravitational waves in scalar-tensor theories of gravity was analyzed to examine properties of cosmological distances inferred from GW measurements. The study found modifications in both the luminosity and angular distances for GW as compared to General Relativity, with implications for gravitational lensing and time-delays between lensed GW and photons in multimessenger events. The Etherington reciprocity law was proven valid for a perturbed universe within a scalar-tensor framework, showing that lensed GW and their lensed electromagnetic counterparts arrive simultaneously, in line with causality constraints.

Summary: An Eulerian Perturbation Theory is introduced to study the clustering of tracers in cosmologies with massive neutrinos, incorporating Effective Field Theory counterterms, IR-resummations, and biasing scheme for one-loop redshift-space power spectrum calculation. Comparisons with synthetic halo catalogues show good agreement on scales up to 0.25 h Mpc(-1), but higher wave-numbers lead to inaccurate estimation of the linear bias parameter. An accurate approximation method is derived to reduce computational cost for loop corrections and accelerate calculations with FFTLoG methods.

Summary: This paper studies the predictions of two modified gravity models beyond linear redshift distortions using N-body simulations and mock galaxy catalogs, finding promising power for testing GR. A major challenge for the future is to create realistic mock galaxy catalogs for both GR and alternative models to fully utilize the statistic power of the DESI survey and understand the impact of systematic effects.

Summary: This study proposes a new method to probe inflationary models of primordial black hole (PBH) production by analyzing the characteristics of the primordial power spectrum profile, specifically focusing on the dip and surrounding scales. The research shows that the properties of PBH scenarios can be quantitatively studied by cross correlating CMB mu-distortions and temperature fluctuations, which may be tested in the next generation of CMB experiments.

Summary: In models of dynamical dark energy and gravity beyond the standard cosmological scenario, estimates of luminosity distance from electromagnetic and gravitational wave sources differ, leaving a unique imprint on the angular power-spectrum of fluctuations. By exploiting the synergy in supernovae and gravitational wave distance measurements, a joint estimator has been constructed to directly probe dark energy fluctuations, providing conclusive evidence for their existence. Additionally, this measurement can also allow for probing the running of the Planck mass, with experimental requirements discussed for detecting these signals.

Summary: By investigating the correlation between topological M-theory and Chern-Simons actions for certain gauge fields, the standard and exotic actions of three-dimensional gravity can be revealed. This study provides a concrete realization of a conjecture by Dijkgraaf et al., stating that the partition function of topological M-theory is equivalent to the partition function of a related theory's black hole.

Summary: The study found that introducing brief periods of nonattractor evolution in cosmological inflation can generate primordial black holes and enhance the spectrum of gravitational waves. For a single epoch of slow-roll violation, the steepest slope of the spectrum has a spectral index n(s) - 1 = 4, while multiple phases of violation result in an enhanced slope.
