In fields such as acoustics, electromagnetism, and quantum physics, the scattering of waves by localized objects is a fundamental phenomenon. Building on this, the present study investigates the energy distribution within a spherical scattering cente

White dwarf symbiotic binaries are detected in X-rays with luminosities in the range of 10$^{30}$ to 10$^{34}$ lumcgs. Their X-ray emission arises either from the accretion disk boundary layer, from a region where the winds from both components colli

Este artigo discute a obra "Robô esmaga", de Alexandre S. Lourenço, com o intuito de demonstrar como algumas de suas histórias são construídas. Nesse sentido, este trabalho aborda algumas noções teóricas da arte sequencial, com destaque para

This paper deals with the design of Excitation and Measurement Patterns (EMPs) for the identification of dynamical networks, when the objective is to identify only a subnetwork embedded in a larger network. Recent results have shown how to construct

Layered franckeite is a natural superlattice composed of two alternating layers of different compositions, SnS$_2$- and PbS-like. This creates incommensurability between the two species along the planes of the layers, resulting in spontaneous symmetr

We report on a direct search for scalar field dark matter using data from LIGO's third observing run. We analyse the coupling of size oscillations of the interferometer's beamsplitter and arm test masses that may be caused by scalar field dark matter

We present an analysis of publicly available X-ray and optical observations of TYC 7275-1968-1, a contact binary, red nova progenitor candidate. The long optical time series of ASAS-SN, SuperWASP, CRTS, GAIA, ASAS-3, and TESS enabled us to improve it
