With the goal of broadening its coverage of astrophysics, PRD hired astrophysicist Enrico Ramirez-Ruiz as an Associate Editor and appointed three experts in astrophysics to its Editorial Board.

Using radioactive tritium, scientists improve laboratory constraints on the overdensity signal of cosmic relic neutrinos by a factor of 100, an advance that should improve the chances of spotting this elusive particle.

A novel kind of generalized global symmetries is uncovered in a large class of familiar 3+1-dimensional gauge theories, including the free Maxwell theory and Yang-Mills gauge theories. These new symmetries, known as the non-invertible global symmetries, do not have inverses and thus go beyond the traditional paradigm of (anti-)unitary transformations. They are implemented by topological duality defects, generalizing the Kramers-Wannier duality defects in 1+1 dimensions. Remarkably, the existence of certain kinds of duality defects is intrinsically incompatible with a trivially gapped phase and hence gives new constraints on renormalization group flows.

Gravitating bodies are typically deformable and deviate from spherical symmetry and even axisymmetry. These deviations are encoded in the body’s so-called mass and current multipole moments. This paper studies leading corrections to binary dynamics when the compact objects involved have arbitrary mass quadrupole moments. These corrections are important in modeling waveforms and interpreting gravitational wave data.

New neutrino-oscillation data show no sign of an anomalous signal seen in previous studies, but the analyses can’t yet fully rule out its presence.
