Modifications to Newtonian dynamics at low accelerations have long been proposed as an alternative to dark matter to explain galaxy rotation curves. More recently, similar corrections have been invoked to interpret anomalies in Cavendish-type laboratory experiments and in the dynamics of wide binary stars, although the latter remain affected by

Context. Superluminous supernovae (SLSNe) are a rare class of transients with peak luminosities 10─100 times greater than those of standard core-collapse supernovae (SNe). The mechanisms powering their extreme brightness remain debated, with circumstellar medium (CSM) interaction, or energy injection from a central engine like a magnetar wind

Context. Advances in data-constrained and data-driven simulations have shed light on the initiation of solar eruptions. These models incorporate observed photospheric magnetic fields. However, because we lack information about the magnetic field in the rest of the solar atmosphere, models rely on extrapolations that, in most cases, neglect the

Extremely high-peaked BL Lac objects—also named extreme blazars—are among the most energetic and persistent extragalactic accelerators in the Universe, defined by a synchrotron emission peaking above 10 17 Hz in X-rays. Such emission is then reprocessed and produces radiation extending deeply into very-high-energy (VHE; energy E > 100 GeV) gamma

Reconstruction of the baryon acoustic oscillation (BAO) signal has been a standard procedure in BAO analyses over the past decade and has helped to improve the BAO parameter precision by a factor of ∼2 on average. The Dark Energy Spectroscopic Instrument (DESI) BAO analysis for the first year (DR1) data uses the "standard" reconstruction framework
