We investigate X-ray isophote twists created by triaxiality differences between the luminous stellar distributions and the dark halos in elliptical galaxies. For a typically oblate luminous galaxy embedded in a more prolate halo formed by dissipationless collapse, the triaxiality difference of ∆T ≃ 0.7 leads to typical isophote twists of 〈∆ψX〉 ≃ 16 ± 19 at 3 stellar effective radii. In a model ...

The ground-state deformations of the Ge isotopes are investigated in the framework of GognyHartree-Fock-Bogoliubov (HFB) and Skyrme Hartree-Fock plus pairing in the BCS approximation. Three different Skyrme parametrizations are used to explore the influence of different effective masses and spin-orbit models. There is generally good agreement for binding energies and deformations (total quadrup...

The isoscalar giant resonances for $^{86}\mathrm{Ge}$ are studied by the quasiparticle finite amplitude method based on covariant density functional theory. In addition to well-known monopole-quadrupole coupling that splits monopole resonance in axially deformed nuclei, a monopole-quadrupole-hexadecupole is identified neutron-rich triaxially nucleus $^{86}\mathrm{Ge}$, leading emergence of dist...

Under warm forming, the damage parameters of extended GTN model are easily affected by temperature, and failure materials under forming is less studied using this model. In paper, based on model, DP590 at different temperatures determined experiment numerical simulation, studying trend changing with temperature. Through analysis shear specimens angles temperatures, we changes in void conditions...
