A recent Suggestion performs a non-parametric analysis of dark energy from cosmological data. Without assuming a functional form of the DE density over time, they find mild evidence of phantom crossing and deviations from Λ⁢CDM. #EdSugg.

RT @APSphysics: Our portfolio of peer-reviewed journals continues to rank among the top publications in physics, according to the 2024 Jour….

Ultralight axions oscillate with high frequencies that must be averaged over in practical calculations. We're highlighting Improved precision implemented in a cosmological code, with potential impacts on solutions to tensions in the Λ⁢CDM model. #EdSugg.

High energy gamma rays can arise from inverse Compton scatting of a photon with an energetic electron. A recent highlight shows how continuous approximations used to model this effect can introduce bias and an improved discrete treatment is needed. #EdSugg.

A new Suggestion performs a full calculation for a solution in 6D Einstein-Maxwell supergravity compactified to four dimensions, showing a separation of scales in the particle spectrum can be achieved, a key ingredient for a realistic model. #EdSugg.

Beyond-the-Standard-Model hyperlight scalar fields may cause fundamental constants to vary over time. A recent highlight comprehensively surveys early- and late-universe data, as well as laboratory observations, to strongly constraint such fields. #EdSugg.

The exact Wentzel–Kramers–Brillouin method is used to study black hole quasinormal modes in the Suggestion. The authors examine previously overlooked logarithmic spirals of Stokes curves and branch cuts, deriving correct results for various models. #EdSugg.

Realistic models of inflation may leave sharp features in the primordial power spectrum. Via simulations, this highlight shows how such signals can persist through the nonlinear evolution of structure formation, leaving clues to the early universe. #EdSugg.

A recent Suggestion presents results from the South Pole Telescope, using their 4-year, 500 deg^2 data set. Measurements of temperature and E-mode polarization in the Cosmic Microwave Background yield cosmological parameters consistent with Planck. #EdSugg.

Cosmic rays interact with the Sun's atmospher to produce the solar steady emission of gamma rays. This highlight presents a 3D Monte Carlo simulation of inverse Compton scattering in the presence of magnetic fields to better model this phenomenon. #EdSugg.

Non-Gaussian aspects of primordial gravitational waves could leave traces in cosmic microwave background temperature and polarization. In this highlight, authors use Planck PR4 data to constrain 11 primordial templates and discuss future advances. #EdSugg.

A new Suggestion proposes to use stacks of HII reionization bubbles detected in upcoming SKA 21-cm data, which should behave like ideal spheres, to constrain the product of angular diameter distance and the Hubble constant. #EdSugg.

A new Suggestion considers ultralight dark photons, which are highly constrained as a dark matter candidate by the potential formation of cosmic strings. The authors discuss mechanisms which can relax such limits and analyze experimental targets. #EdSugg.

The thermal Sunyaev-Zel'dovich effect conveys information on galaxy clusters in a non-Gaussian manner. A recent highlight shows how higher-order statistics applied to experiments can provide better cosmological constraints than the power spectrum alone.

New results from lattice QCD are used to compute the Compton amplitude subtraction function. This is a key component of the proton-neutron mass difference and the proton charge radius, and this Suggestion paves the way for a precise determination. #EdSugg.

We're highlighting an extremely high energy (~300 TeV) photonlike air shower event seen by the Carpet-3 detector, which may be the highest-known-energy event associated with a Gamma Ray Burst. Such events may suggest exotic production mechanisms. #EdSugg.

The muon anomalous magnetic moment remains subject to conflicting theory calculations. A recent Suggestion uses lattice QCD to compute the hadronic vacuum polarization contribution in so-called short and intermediate windows with high precision. #EdSugg.

A recent highlight revisits causality constraints on radiative transfer in relativistic hydrodynamics. Standard methods neglect the finite speed of light, but the authors show this can be resolved with stable covariant radiative transfer equations. #EdSugg.

We're highlighting a pair of paper in PRL and PRD which demonstrate how black holes with non-singular solutions can form in modified gravity theories in 5 or higher dimensions. #EdSugg.

This highlight examines the cosmic calibration tension between distances inferred from Baryon Acoustic Oscillation data and supernovae. Resolving it suggests either modifying the pre-recombination expansion history or changes in multiple epochs. #EdSugg.
