The subject of boosted fluxes of dark matter or cosmic relic neutrinos via scattering on cosmic rays has received considerable attention recently. This article investigates the boosted neutrino flux from the scattering of cosmic rays and the so-far u...

We extend the Quantum Memory Matrix (QMM) framework—previously shown to unify gauge interactions and reproduce cold dark matter phenomenology—to account for the observed late-time cosmic acceleration. In QMM, each Planck-scale cell carrie...

Calibrating the ages, masses, and radii of stars on the upper main sequence depends heavily on accurate measurements of the effective temperature (Teff) and surface gravity (logg). These parameters are difficult to obtain meticulously due to the natu...

We investigate BZT shocks and the QCD phase transition in the dense core of a cold quark star in beta equilibrium subject to the multicomponent van der Waals (MvdW) equation of state (EoS) as a model of internal structure. When this system is express...

We present a conditional variational autoencoder (CVAE) that generates stellar spectra covering 4000 ≤ Teff ≤ 11,000 K, 2.0≤logg≤5.0 dex, −1.5≤[M/H]≤+1.5 dex, vsini≤300 km/s, ξt between 0 and 4 km/s, and for any instrume...

Extremely powerful flares releasing energy well above 1032 erg are rare compared to the typical manifestations of solar activity, which are already being routinely monitored by the existing Space Weather network—with some level of predictabilit...

We revisit 77 relaxed (extra)solar multibody (sub)systems containing 2–9 bodies orbiting about gravitationally dominant central bodies. The listings are complete down to (sub)systems with 5 orbiting bodies and additionally contain 33 smaller sy...
