Beyond Spin: QCD Magnetars
Rachid Ouyed
We present a unified framework in which anomalous X-ray pulsars (AXPs), soft gamma-ray repeaters (SGRs), superluminous supernovae (SLSNe-I), luminous fast blue optical transients (…
Optical Flares in the Luminous Fast Blue Optical Transient AT2022tsd ("Tasmanian Devil")
Rachid Ouyed
We propose that luminous fast blue optical transients (LFBOTs) signal the delayed conversion of a massive neutron star (NS; M_NS > ~1.8 Msun) into a highly magnetized hybrid star (…
Late-Onset Energy Injection in Type Ic SNe and W-Shaped O II Absorption in SLSNe-I
Rachid Ouyed
We show that delayed (weeks-months) energy injection into expanding Type Ic supernova (SN) ejecta can reproduce the luminosity and spectral evolution of hydrogen-poor superluminous…
Modeling the Light Curve and Spectra of SN 2023aew
Rachid Ouyed
We propose that the delayed conversion of a neutron star (NS) into either a quark star (QS) or a hybrid star (HS), occurring approximately 105-109 days after the supernova (SN) exp…
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…
