This paper studies dark matter in a spontaneously broken hidden U(1). The initial overabundant dark matter density is generated through the freeze-out mechanism. Because the subsequent first order phase transition becomes supercooled, the vacuum transition generates entropy, diluting the DM density to its current value. The MeV–GeV transition also produces nano-Hz gravitational waves potentially detectable by pulsar timing arrays such as NANOGrav.

Advanced cryogenic detectors, e.g. qubit-based sensors or Kinetic Inductance Detectors (KIDs), often offer resolutions larger than a single detected photon’s energy. The authors demonstrate that commonly used statistical methods for calibration of such detectors can introduce systematic biases, leading to inaccurate energy scale and resolution measurements. This stems from an assumption of independence between detector resolution and photon number, which breaks down once realistic effects like position-dependent phonon collection efficiency or Fano fluctuations are taken into account. Finally, a method of correcting for said effects is proposed.

The JIMWLK evolution equations describe high-energy scattering and the gluon saturation regime of QCD. As an infinite hierarchy of coupled, non-linear equations, approximations are required to make any phenomenological predictions. One widely-used approximation in which one assumes many quantities are Gaussian-distributed random variables, is known to be accurate for a simple class of initial conditions. The authors explicitly demonstrate that this Gaussian approximation fails to accurately describe full JIMWLK evolution beyond this simplest configuration, which may have significant implications for heavy ion collisions.

p-adic string theory asks how much of string physics really depends on ordinary spacetime geometry. Quantum gravity may replace smooth short-distance geometry with more primitive or nonlocal structures; p-adic models provide a laboratory where the notion of distance is very different. This manuscript tests whether one of the most basic stringy signatures – the rapid high-energy growth of states – survives in such a setting. Simple tree models fail, but a natural p-adic spectrum on the unit circle reproduces the usual coarse string entropy growth, with log-periodic corrections. The result probes which aspects of string thermodynamics are geometric and which are more universal.

Launching jets from collapsar black holes requires strong magnetic field and rapid rotation. However, strong fields can spin down the collapsar black holes before the jet can be launched. In this work, the authors study the effect of neutrino cooling on this jet launching process. They show that neutrino cooled disks can continue to feed angular momentum to the black hole without the opposing spin-down effect that comes from general mass accretion. Thus, the spin of the black hole remains sufficient high to launch a jet from a collapsar environment to produce a long gamma-ray burst.

Their results provide new avenues to mitigate the baryonic uncertainties in lensing analyses and to explore baryonic explanations for the anomalously low tSZ power observed in the CMB measurements.

Though ubiquitous in modern perturbative calculations in quantum field theory, Feynman diagrams for scattering amplitudes do not make the property of causality, that no signal can travel faster than light, manifest. The authors construct diagrammatic rules for calculation of particle scattering probabilities in perturbation theory that are explicitly causal. Infrared divergences familiar in a Feynman diagram approach that correspond to correlations over arbitrary distances are summed over at the diagrammatic level in this formalism, and may produce new insights into their all-orders structure.

Self-force theory, while initially adapted for the extreme mass-ratio case of the gravitational two-body problem, has in fact applications in wider contexts. Here, the approach is incorporated into effective one-body theory to develop a waveform model for the entire non-spinning binary coalescence process: inspiral, plunge, merger, and ringdown. Where the approaches can be compared, the model is found to be highly competitive in relation to existing waveform models and numerical relativity.

Understanding the saturation regime, in which the partons in the proton all carry a small fraction $x$ of the proton’s energy, is vital for testing QCD in a strongly non-linear state. The authors study an approximation to the equation that governs evolution at small-$x$, the Balitsky-Kovchegov equation, and extract its non-perturbative initial condition through Bayesian inference using extant experimental data. These results are central to further analyses of the proton’s wavefunction at the upcoming Electron-Ion Collider.

It has been long established that the promotion of parameters of a theory to fields can reveal certain properties of the original QFT. Here, the authors generalize this procedure by making these parameter fields partially dynamical, while determining their dynamics by a top-down approach from string theory. This new feature reveals generalized symmetries and topological structures, providing a deeper understanding of them and their associated anomalies.

The memory-burden effect is expected to alter the evaporation rate of black holes as the emitted energy becomes comparable to the black hole’s total energy, opening up a possibility for lighter primordial black holes to survive as a component of dark matter. In this Suggestion, the authors examine the production of a diffuse gamma ray flux from such evaporation processes. Taking into account the interaction with background radiation at energies above 10^5 GeV, and secondary emission from the electromagnetic cascades in extragalactic space, they set new bounds on the parameter space of such black holes.

Modern techniques for calculation of scattering amplitudes have revolutionized precision predictions in perturbative gauge theories, resulting in closed-form expressions for multi-leg and multi-loop amplitudes that can be applied to understanding high energy jet production at hadron colliders. Through an impressive calculation, the authors demonstrate that these modern techniques remain sufficiently powerful to extend the state-of-the-art to five-point, three-loop Feynman integrals that contribute to multi-jet production rates at next-to-next-to-next-to-next-to-leading order in perturbation theory.

The authors perform a model-independent, non-parametric reconstruction of dark energy density using DESI BAO, CMB, and SNe data. Their method employs a piecewise polynomial interpolation without assuming a functional form of dark energy density. This analysis shows mild but consistent deviations from ΛCDM and evidence for phantom crossing. The framework is robust, flexible and can be readily used for next-generation precision cosmological surveys.

Ultralight axions, as dark matter across a wide mass range, require precise, time-averaged treatments for reliable cosmological predictions. An accurate implementation of this technique in AxiECAMB, a full cosmological Boltzmann code, allows a precision analysis for current and future CMB and LSS missions. These improvements significantly enhance model predictions and may impact the role of ultralight axions in addressing ΛCDM tensions.

Inverse Compton scattering of photons by high energy electrons produces some of the highest energy gamma-rays observed on earth from astronomical sources. Measuring this gamma-ray spectrum yields deep insights into the distribution of high energy electrons in distant astronomical sources. In this paper, the authors point out that the standard continuous approximations to model this process can overestimate the shape and cutoff of the high energy electron propulation. This study can help yield valuable insights on the interpretation of gamma-ray data from pulsars.

Some theoretical cosmological models naturally predict that certain fundamental constants of Nature—such as the electromagnetic fine-structure constant or the electron mass—may vary over time, with these variations increasing with redshift. This paper provides a comprehensive investigation of the early-Universe dynamics and phenomenology of such models. It also presents joint constraints from both early- and late-Universe data, combining laboratory experiments with a range of cosmological observations, resulting in the most stringent limits on these models to date.

Compactifications of higher dimensional theories to four dimensions is one way to understand the real world theories. However, to obtain realistic lower dimensional effective theories, the scale separation upon compactification is crucial, so the extra dimensions effectively decouple. Doing a full calculation, the authors show that the compactification of a particular supergravity theory in six dimensions, exhibits separation of scales.

Sharp features in the primordial power spectrum are a natural prediction of many UV-complete models of inflation. The authors use dedicated N-body simulations to demonstrate that features consistent with CMB constraints persist throughout the nonlinear regime of structure formation and thus may play a role in explaining tensions between the CMB and observations of the late-time matter distribution. While further numerical work is necessary to resolve the degeneracy with other effects, this study is a pioneering foundation for future research.

Ultralight dark photons, corresponding to a broken U(1) gauge symmetry, are an interesting candidate for dark matter. However, they are strongly constrained by the formation of cosmic strings via backreaction on a dark Higgs field, which spoils the viability of the scenario for detectable ranges of coupling and mass parameters. This work explores the problem in detail and shows how various additional mechanisms can relax the constraints, along with analyzing the detection prospects for such models.
