abstract
We give analytical arguments and demonstrate numerically the existence of black hole solutions of the $4D$ Effective Superstring Action in the presence of Gauss-Bonnet quadratic curvature terms. The solutions possess non-trivial dilaton hair. The hair, however, is of ``secondary" type", in the sense that the dilaton charge is expressed in terms of the black hole mass. Our solutions are not covered by the assumptions of existing proofs of the ``no-hair" theorem. We also find some alternative solutions with singular metric behaviour, but finite energy. The absence of naked singularities in this system is pointed out.

UV completions of scalar-tensor EFTs
One-loop matching shows heavy spin-0, 1/2, or 1 matter generates explicit Wilson coefficients for scalar-tensor EFTs; shift-symmetric scalar-Gauss-Bonnet gravity is not produced in this model class, while shift-symmet...

Novel extended inner shadow in images of Johannsen-Psaltis black holes with thin accretion disks
JP black holes with non-closed horizons produce an 'extended inner shadow' distinct from the ordinary inner shadow, and all image scales (inner shadow, photon ring, peak positions) grow monotonically with |ϵ3|.

Spacetime of rotating black holes surrounded by massive scalar charges
Spectral methods construct leading-order spinning black-hole spacetimes with massive scalar hair for spin a≤0.8 and scalar mass µ≤0.2/M.

Challenges in the nonlinear evolution of unequal mass binaries in sGB gravity
First full merger simulations of 2:1 and 3:1 black hole binaries in scalar-Gauss-Bonnet gravity, with weak-coupling dephasing matching PN predictions but strong-coupling results limited by initial-data transients.

A Critical Point on the Hairy Black Hole Phase Boundary in the Improved Holographic Einstein-Maxwell-Dilaton Theory
In the improved holographic EMD model, two hairy black hole phases are separated by a U-shaped boundary whose lower branch is first-order and upper branch third-order, meeting at (mu_B,T)=(765.51,86.54) MeV.

An innovative black hole solution and thermodynamic properties in higher-order curvature gravity with a scalar field
A reverse-engineered modified-Schwarzschild solution in scalar-coupled higher-curvature gravity is presented, whose headline 'weaker singularity' claim is contradicted by its own Kretschmann-scalar results (r^-9 versu...
