How much mass is contained in an arbitrary sphere centered on the Sun? This highlight uses the divergence theorem and acceleration of millisecond pulsars to estimate. In future this method may help constrain the local distribution of dark matter. #EdSugg journals.aps.org/prd/abstract/1…

Join APS TV Host Clara Nellist as she sits down with the editors of PRX Intelligence, a new @APSPhysics journal. Watch them introduce their vision for a publication dedicated to research at the intersection of physics, AI & machine learning. #APSSummit26 youtu.be/3UpwDhHLGRE

The APS Global Physics Summit is underway and we're looking forward to a week of great talks and events in Denver! summit.aps.org #APSSummit26

Using data from the Simons Array, a new Suggestion reports a search for polarization oscillation from the Crab Nebula. The authors put new bounds on axion-like dark matter, but previous hints of a signal from POLARBEAR are not confirmed. #EdSugg journals.aps.org/prd/abstract/1…

The scalar spectral index nₛ characterizes inflationary models. A recent highlight cautions that tensions between Baryon Acoustic Oscillation- and Cosmic Microwave Background-derived measurements may reflect larger differences in the data sets. #EdSugg journals.aps.org/prd/abstract/1…

High electron temperatures induce a correction to the thermal Sunyaev-Zeldovich effect. By stacking precise data from galaxy clusters seen by the Atacama Cosmology Telescope, a new Suggestion extracts an average electron temperature of 8.5 keV. #EdSugg journals.aps.org/prd/abstract/1…

This highlight explores a generalized Schur index in N=2 Superconformal Field Theories. This gives a partition function with a continuous variable which appears to relate different theories through nontrivial mappings of the parameter. #EdSugg journals.aps.org/prd/abstract/1…

A recent Suggestion demonstrates the holographic duality between the rate of growth of complexity of quantum states excited by local operators in 2-D conformal field theories and the radial momentum of particles in 3-D anti–de Sitter spacetimes. #EdSugg journals.aps.org/prd/abstract/1…

The Hubble tension remains a stubborn problem in cosmology. This highlight shows that even if common assumptions about Baryon Acoustic Oscillations are biased, the data still does not favor post-recombination solutions to the tension. #EdSugg journals.aps.org/prd/abstract/1…

In this Suggestion, the authors consider sub-GeV dark matter which can undergo p-wave annihilation to hadrons. The early injection of pions and kaons can impact Big Bang nucleosynthesis, leading to constraints on models in this mass range. #EdSugg journals.aps.org/prd/abstract/1…

We're highlighting this work, which extends results for the scattering of a graviton off a compact spinning object. The authors conduct a full one-loop Compton scattering analysis including 2nd post-Minkowskian and hexadecapolar orders. #EdSugg journals.aps.org/prd/abstract/1…

A recent Suggestion constructs analytic solutions for small-x helicity Parton Distribution Functions in the limits of large color and flavor number. Results largely agree with other methods and provide insight into the proton spin puzzle. #EdSugg journals.aps.org/prd/abstract/1…

The Heavy Flavor Averaging Group carefully compiles data from many experiments to establish state of the art knowledge in flavor physics. We're highlighting a recent update on b- and c- hadrons and tau properties from results as of late 2023. #EdSugg journals.aps.org/prd/abstract/1…

Binary black hole mergers are characterized by quasinormal modes, which are often studied numerically. This Suggestion develops an analytical approach using Green's functions as a step towards understanding the complicated phases of the inspiral. #EdSugg journals.aps.org/prd/abstract/1…

A recent Suggestion examines the performance of a semiclassical approach to charmonium in quark-gluon plasma compared to a full quantum description. The approximation performs quite well thanks to rapid classicalization in the thermal bath. #EdSugg journals.aps.org/prd/abstract/1…

A recent highlight examines gravitational lensing through the formalism of scattering theory. The authors derive the correspondence between the diffraction integral approach and scattering amplitudes, and map out the equivalence for various limits #EdSugg journals.aps.org/prd/abstract/1…

In a new Suggestion, the authors calculate the total flux of neutrinos at Earth from stars in our galaxy. Taking into account various emission processes and stellar evolution for a range of masses, they estimate the spectrum and dominant sources. #EdSugg journals.aps.org/prd/abstract/1…

In our first Suggestion of the New Year, researchers compare predictions of the diffuse 𝛾-ray flux in our galaxy produced by cosmic ray propagation with data from LHAASO and Fermi-LAT, finding an excess of observed 𝛾-rays above 100 TeV. #EdSugg journals.aps.org/prd/abstract/1…

This highlight uses general relativistic magnetohydrodynamic simulations of accretion disks to study our ability to determine black hole spins from X-ray data, finding only high-spin systems are likely to give robust results with current models. #EdSugg journals.aps.org/prd/abstract/1…

A recent Suggestion following the bootstrap program applies a new numerical method to thermal quantum conformal field theories. The authors' approach combines the Kubo-Martin-Schwinger condition, thermal dispersion relations, and neural networks. #EdSugg journals.aps.org/prd/abstract/1…
