Abstract

We constructed a (2+1)-dimensional gravastar whose interior region was characterized by a noncommutative geometry with Gauss-Bonnet corrections, while the exterior region was described by a Gauss-Bonnet-modified BTZ solution. The two geometries were joined across a thin shell using the generalized junction formalism, from which we derived the surface equations of state. We investigated the energy conditions at the shell, determining the parameter regimes under which the null, weak, and strong energy conditions were satisfied. We also analyzed the thermodynamic properties of the noncommutative interior region, including the temperature, entropy, and heat capacity.

Collective Properties of Gravitational Perturbations in Thermal Environments on a Dynamical Background

A thermal plasma dresses soft gauge fields, turning them into collective modes with a plasmon gap and Landau damping. In this paper, we ask whether a thermal radiation plasma does the same to gravitational perturbations. For gravity, the thermal soft scale coincides with the Hubble rate. Any such gap therefore lies at the horizon scale, where the expansion of the background cannot be neglected. We model radiation by a conformal scalar and compute its linear response to metric perturbations directly on a flat FLRW background. We test this response against the diffeomorphism Ward identities. The adiabatic dispersion relation yields a gapped collective mode with $ω_p^2 = 8\mathcal{H}^2/5$, where $\mathcal{H}$ is the conformal Hubble rate. The imaginary part of its frequency, however, is dominated by the background expansion and does not represent Landau damping. In the radiation background, the tensor modes obey a real-time integro-differential equation that reproduces Weinberg's damping of gravitational waves. The initial-time boundary of the retarded response keeps superhorizon modes frozen until horizon reentry despite the gap. The superhorizon growth found in earlier analyses arises from discarding the memory of the retarded response and from a local-equilibrium state prescription that violates the Ward identities. More generally, the Ward identities forbid any local state response beyond the collisionless kernel.

Black hole binaries in shift-symmetric Einstein-scalar-Gauss-Bonnet gravity

In shift-symmetric Einstein-scalar-Gauss-Bonnet gravity, stationary black holes have a non-vanishing scalar charge. During the inspiral, the phase evolution is modified by several effects,primarily an additional scalar dipole radiation, which enters at -1PN order. Including corrections up to 2PN, this effect accelerates the inspiral when compared to general relativity, but changes in the conservative dynamics may do the opposite. Using fully non-linear numerical simulations of quasi-circular, comparable mass binaries, we characterize the late stages of the orbital dynamics. We find that the overall effect is still an accelerated merger phase for the modified gravity case, but noticeably less than predicted by PN alone, which we relate to the conservative dynamics, showing that at the late inspiral stage more energy must be emitted in scalar-Gauss-Bonnet gravity to induce a given change in frequency. In longer signals, this may lead to a distinctive frequency evolution relative to general relativity as the binary approaches merger, but its effect close to merger is to suppress the difference with GR. This work suggests we may need to revisit existing constraints on the theory that are obtained assuming PN approximations apply up to merger, or based on order by order approximations that neglect backreaction effects on the metric, and shows the importance of including non-linear effects that modify the gravitational sector in the strong field regime.

Symmetries of cosmological perturbations: The residual low-multipole ambiguity

In cosmology, long-wavelength modes are related to large-gauge transformations (LGT), i.e. changes of coordinates that modify the physical geometry of the cosmological patch. These LGTs stand as bona-fide symmetries of cosmological perturbation theory with various applications, from consistency relations constraining cosmological correlators to non-linear conservation laws in the separate-universe approach. In this work, we revisit LGTs and derive two new results. First, we show that the global symmetries already identified in the literature can be extended to local infinite-dimensional symmetries. The associated generators depend on arbitrary functions of time, and generate low-multipole modes that modify the mean curvature energy and the angular momentum of the patch, demonstrating their physical nature. We propose to interpret these low-multipole soft modes as a new cosmological-frame ambiguity that needs to be fixed prior to evaluating cosmological observables. Second, we demonstrate that the adiabatic cosmological perturbations generated by LGTs deform but preserve all the explicit and hidden Killing symmetries of the background geometry. As such, long-wavelength modes stand as a concrete example of algebraically-special cosmological perturbations of Petrov-type O, and inherit the conformal group as isometries and a set of four deformed Killing-Yano tensors and their associated Killing tensors. This opens the possibility to study their effect on cosmological observables in a fully analytic manner.
