Accidental Peccei-Quinn symmetry from gauged U(1) and a high quality axion
Journal of High Energy PhysicsWe construct explicit models that solve the axion quality problem originating from quantum gravitational effects. The general strategy we employ is to supplement the Standard Model and its grand unified extensions by an anomaly-free axial U(1) a symmetry

New axion and hidden photon constraints from a solar data global fit
, 2015 We present a new statistical analysis that combines helioseismology (sound speed, surface helium and convective radius) and solar neutrino observations (the $^8$B and $^7$Be fluxes) to place upper limits to the properties of non standard weakly ...

Molecular Ecology, Volume 35, Issue 9, May 2026.ABSTRACT Biogeographic breaks, that is, shifts in overall species composition, are expected to be associated with phylogeographic breaks because of shared ecological or evolutionary factors operating at both the interspecific and intraspecific level.

DarkGEO: a large-scale laser-interferometric axion detector
New Journal of PhysicsAxions and axion-like particles (ALPs) are leading candidates for dark matter. They are well motivated in many extensions of the standard model and supported by astronomical observations.

Reduced snow cover at the alpine treeline: resistance and recovery of saplings
New Phytologist, Volume 250, Issue 3, Page 1492-1509, May 2026.Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Curl up with a good B: detecting ultralight dark matter with differential magnetometry
Journal of High Energy PhysicsUltralight dark matter (such as kinetically mixed dark-photon dark matter or axionlike dark matter) can source an oscillating magnetic-field signal at the Earth’s surface, which can be measured by a synchronized array of ground-based magnetometers.
