The Quark-Nova model for FRBs: model comparison with observational data
Rachid Ouyed, Denis Leahy, Nico Koning
We utilize the Quark-Novae (QN) model for Fast Radio Bursts (FRBs; Ouyed et al. 2021; arXiv:2005.09793) to evaluate its performance in reproducing the distribution and statistical…
Quark-Novae in the outskirts of galaxies: An explanation of the Fast Radio Burst phenomenon
Rachid Ouyed, Denis Leahy, Nico Koning
We show that old isolated neutron stars in groups and clusters of galaxies experiencing a Quark-Nova phase (QN: an explosive transition to a quark star) may be the source of FRBs.…
A Quark-Nova in the wake of a core-collapse Supernova: a unifying model for long duration Gamma-Ray Bursts and Fast Radio Bursts
Rachid Ouyed, Denis Leahy, Nico Koning
[Abridged] By appealing to a Quark-Nova (QN; the explosive transition of a neutron star to a quark star) in the wake of a core-collapse Supernova explosion of a massive star, we de…
Critical assessment of nuclear sensitivity metrics for the r-process
Zachary Shand, Rachid Ouyed, Nico Koning +3
Any simulation of the r-process is affected by uncertainties in our present knowledge of nuclear physics quantities and astrophysical conditions. It is common to quantify the impac…
The Superluminous (Type I) Supernova ASASSN-15lh : A case for a Quark-Nova inside an Oxygen-type Wolf-Rayet supernova remnant
Rachid Ouyed, Denis Leahy, Luis Welbanks +1
We show that a Quark-Nova (QN; the explosive transition of a neutron star to a quark star) occurring a few days following the supernova explosion of an Oxygen-type Wolf-Rayet (WO)…
Quark-nova compact remnants: Observational signatures in astronomical data and implications to compact stars
Rachid Ouyed, Denis Leahy, Nico Koning +1
Quark-novae leave behind quark stars with a surrounding metal-rich fall-back (ring-like) material. These compact remnants have high magnetic fields and are misconstrued as magnetar…
