The ⁵⁸Ni(n,γ) cross section has been measured at the neutron time of flight facility n_TOF at CERN, in the energy range from 27 meV up to 400 keV. In total, 51 resonances have been analyzed up to 122 keV. Maxwellian averaged cross sections (MACS) hav... Read More about Experimental neutron capture data of 58 Ni from the CERN n-TOF facility.

The velocity dispersions of stars near the Sun are known to increase with stellar age, but age can be difficult to determine, so a proxy like the abundance of α elements (e.g., Mg) with respect to iron, [α/Fe], is used. Here we report an unexpected b... Read More about A new stellar chemo-kinematic relation reveals the merger history of the milky way disk.

Cloud angular momentum and effective viscosity in global SPH simulations with feedback (2014)
Journal Article
Williamson, D. J., Thacker, R. J., Wurster, J., & Gibson, B. K. (2014). Cloud angular momentum and effective viscosity in global SPH simulations with feedback. Monthly notices of the Royal Astronomical Society, 442(4), 3674-3685. https://doi.org/10.1093/mnras/stu1121

We examine simulations of isolated galaxies to analyse the effects of localized feedback on the formation and evolution of molecular clouds. Feedback contributes to turbulence and the destruction of clouds, leading to a population of clouds that is y...

Impact of the uncertainty in α-captures on 22Ne on the weak s-process in massive stars (2014)
Presentation / Conference Contribution
Nishimura, N., Hirschi, R., Pignatari, M., Herwig, F., Beard, M., Imbriani, G., Görres, J., Deboer, R. J., & Wiescher, M. Impact of the uncertainty in α-captures on 22Ne on the weak s-process in massive stars. Presented at ORIGIN OF MATTER AND EVOLUTION OF GALAXIES 2013: Proceedings of the 12th International Symposium on Origin of Matter and Evolution of Galaxies (OMEG12), Tsukuba, Japan

Massive stars at solar metallicity contribute to the production of heavy elements with atomic masses between A = 60 and A = 90 via the so-called weak s-process (which takes place during core He and shell C burning phases). Furthermore, recent studies... Read More about Impact of the uncertainty in α-captures on 22Ne on the weak s-process in massive stars.

Given an alternating trilinear form T ∈ Alt(×3Vn) on Vn =V(n,F) let LT denote the set of T-singular lines in PG(n-1)=PVn, consisting that is of those lines 〈a,b〉 of PG(n-1) such that T(a, b, x) = 0 for all x ∈ Vn. Amongst the immense profusion of d... Read More about Some noteworthy alternating trilinear forms.

In contrast to the spatial Bell’s inequalities which probe entanglement between spatially-separated systems, the Leggett-Garg inequalities test the correlations of a single system measured at different times. Violation of a genuine Leggett-Garg test... Read More about Leggett-Garg inequalities.

Monthly notices of the Royal Astronomical Society, 438(2), 1208-1222. https://doi.org/10.1093/mnras/stt2267

To study the star formation and feedback mechanism, we simulate the evolution of an isolated dwarf irregular galaxy (dIrr) in a fixed dark matter halo, similar in size to Wolf–Lundmark–Melotte, using a new stellar feedback scheme.
