Quantum modified inertia: application to galaxy rotation curves
European Physical Journal C: Particles and FieldsThis work explores modified inertia in the context of galactic dynamics by investigating the consequences of introducing bounds on acceleration. Building on earlier ideas related to maximal acceleration and quantum speed limits, an effective framework is

Raising galaxy rotation curves via dressing
We present a manifestly diffeomorphism-invariant simple model of galaxy dynamics obtained by applying the dressing field method (DFM) to a general relativistic system comprising the metric and four scalar fields, phenomenologically representing the four ...

Modified gravity theories and dark matter models tested by galactic rotation curves
, 2014 Bose-Einstein condensate dark matter model and Randall-Sundrum type 2 brane-world theory are tested with galactic rotation curves. Analytical expressions are derived for the rotational velocities of test particles around the galactic center in both cases.

A new empirical fit to galaxy rotation curves
Frontiers in Astronomy and Space SciencesWe present a new empirical model for galaxy rotation curves that introduces a velocity correction term ω, derived from observed stellar motion and anchored to Keplerian baselines.

The mass distribution in early-type disc galaxies:declining rotation curves and correlations with optical properties [PDF]
, 2007 We present rotation curves for 19 early-type disc galaxies (S0-Sab). The galaxies span a B-band absolute magnitude range from -17.5 to -22, but the majority have a high luminosity with M-B

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Many body gravity and the galaxy rotation curves
European Physical Journal C: Particles and FieldsA novel theory was proposed earlier to model systems with thermal gradients, based on the postulate that the spatial and temporal variation in temperature can be recast as a variation in the metric.
