Low‐Energy Atomic Scattering: S‐Wave Relation Between the Interaction Potential and the Phase Shift
Annalen der Physik, Volume 537, Issue 11, November 2025.The validity of the on‐shell approximation for s‐wave scattering is examined across one, two, and three dimensions using exactly solvable model interaction potentials. By comparing exact and approximate s‐wave components of the interaction potential, the analysis reveals that the approximation improves with increasing momentum and decreasing ...

Xarxes internacionals d'art, ciència i tecnologia
Artnodes, 2007 Durant aquesta conversa, Roger Malina reflexiona sobre la relació entre art, ciència i tecnologia, considerant-les no com a disciplines independents sinó connectades i que comparteixen els mateixos mitjans.

Astronomische Nachrichten, Volume 346, Issue 9, November 2025.ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

3D numerical model of the Omega Nebula (M17): simulated thermal X-ray emission
, 2009 We present 3D hydrodynamical simulations of the superbubble M17, also known as the Omega nebula, carried out with the adaptive grid code yguazu'-a, which includes radiative cooling. The superbubble is modelled considering the winds of 11 individual stars
