This study evaluates the performance and applicability of the
high-order Spectral-Difference (SD) method in astrophysical
contexts. We begin by analyzing the advantages and disadvantages of
SD relative to the widely used Finite-Volume (FV) methods...
Over the last century, the construction and discovery of the
Standard Model of particle physics has been one of the greatest
accomplishments in physics. To explore this new frontier, we built
larger and larger colliders utilizing the two charged...
What is common among a magnet, a halibut, a rack of laundry,
cubes of ice, superconductor, and the Higgs boson? The concept of
spontaneous symmetry breaking is a common theme for many natural
phenomena. I'll describe the basic concept and its...
At the center of nearly every galaxy in the Universe resides a
supermassive black hole. When galaxies collide, their supermassive
black holes sink to the center of the newly forming galaxy. There
in this nascent galactic nucleus a supermassive black...
Abstract: We construct a family of
asymptotically flat Cauchy data for the Einstein vacuum equations
that contain no trapped surfaces, yet whose future development
gives rise to multiple strongly causal independent trapped
surfaces. In particular...
Recent results from KiDS-Legacy cosmic shear analyses show that
refined modelling of systematic effects can reconcile previously
low estimates of the structure growth parameter with Planck CMB
predictions. This underscores the importance of accurate...
