Empirical flare energy limits for the largest historical sunspots
Extreme solar particle events (ESPEs) reveal that the Sun can occasionally produce eruptions significantly more energetic than those observed in the modern era. These events are thought to originate from powerful coronal mass ejections (CMEs), typically associated with large sola...

Abstract We construct and characterise a sample of 146 little red dots (LRDs) across 2.0 < z < 9.3, selecting all sources with v-shaped UV-optical continua from JWST NIRSpec/PRISM spectra and compact morphologies in NIRCam/F444W imaging. We show that LRD continuum spectra are wel...

Clifford(11,1) String Theory I: Geometry
Abstract This paper explores tachyonic, open bosonic string theory in which fermions are not strings, but rather reside on the D-brane boundary of open strings. The open-string tachyon is identified with a Higgs field transforming in the adjoint representation. The fermions of a...
