Proton elastic scattering on calcium isotopes from chiral nuclear optical potentials

T. R. Whitehead, Y. Lim, J. W. Holt

We formulate microscopic optical potentials for nucleon-nucleus scattering from chiral two- and three-nucleon forces. The real and imaginary central terms of the optical potentials…

Understanding the mirror asymmetry in Gamow-Teller transition rates between Al($β^-$)Si and P($β^+$)Si

L. Xayavong, N. A. Smirnova, Y. Lim

The long-standing discrepancy between shell-model and experimental values of the mirror asymmetry in Gamow-Teller transition rates for Al($β^-$)Si and P($β^…

Dark Matter Heating in Evolving Proto-Neutron Stars: A Two-Fluid Approach

Adamu Issifu, Prashant Thakur, Davood Rafiei Karkevandi +4

Neutron stars (NSs) provide a unique laboratory to probe dark matter (DM) through its gravitational imprint on stellar evolution. We use a two-fluid framework with non-annihilating…

Microscopic optical potential from chiral effective field theory

T. R. Whitehead, Y. Lim, J. W. Holt

We formulate a microscopic optical potential from chiral two- and three-body forces. The real and imaginary central terms of the optical potential are obtained from the nucleon sel…

Realistic evaluation of Coulomb potential in spherical nuclei and test of the traditional approach

L. Xayavong, Y. Lim

A realistic evaluation of Coulomb potential has been made for some selected nuclei using the available model-independent data for the charge density and the recent development of C…

Bayesian modeling of the nuclear equation of state for neutron star tidal deformabilities and GW170817

Y. Lim, J. W. Holt

We present predictions for neutron star tidal deformabilities obtained from a Bayesian analysis of the nuclear equation of state, assuming a minimal model at high-density that negl…

The limits of the nuclear landscape explored by the relativistic continuum Hatree-Bogoliubov theory

X. W. Xia, Y. Lim, P. W. Zhao +8

The ground-state properties of nuclei with 8 Z 120 from the proton drip line to the neutron drip line have been investigated using the relativistic continuum Hartree-Bo…

Far-UV Observations of a Thermal Interface in the Orion-Eridanus Superbubble

J. Kregenow, J. Edelstein, E. Korpela +8

Diffuse far-UV emission arising from the edge of the Orion-Eridanus superbubble was observed with the SPEAR imaging spectrometer, revealing numerous emission lines arising from bot…

Refining the isovector component of the Woods-Saxon potential

L. Xayavong, Y. Lim, N. A. Smirnova +1

We investigate the isovector component in the phenomenological mean field model of nuclei. Lane's isospin dependence, initially proposed for the nuclear optical potential, is reexa…
