SACRA-K: A Performance-Portable Numerical Relativity Code with Kokkos
Ming-Zhe Han, Kenta Kiuchi, Masaru Shibata
We present SACRA-K (SimulAtor for Compact objects in Relativistic Astrophysics with Kokkos), a performance-portable numerical relativity code ported from the Fortran code SACRA-MPI…
Subsolar-mass binary mergers of strange stars and neutron stars: gravitational waves and ejecta
Yong Gao, Ming-Zhe Han, Kenta Kiuchi +3
We present the first numerical-relativity simulations of subsolar-mass binary strange star (SS) mergers and compare with binary neutron star (NS) mergers across equations of state,…
Dependence of postmerger properties on the thermal heating efficiency in neutron star mergers
Ming-Zhe Han, Yong Gao, Kenta Kiuchi +1
We systematically perform numerical-relativity simulations for equal-mass binary neutron star mergers for the models varying the thermal index with three different equ…
Bulk properties of PSR J0030+0451 inferred with the compactness measurement of NICER
Chuan-Ning Luo, Shao-Peng Tang, Ming-Zhe Han +3
In 2019, Neutron star Interior Composition ExploreR (NICER) mission released its findings on the mass and radius of the isolated neutron star (INS) PSR J0030+0451, revealing a mass…
Upper Limit of Sound Speed in Nuclear Matter: A Harmonious Interplay of Transport Calculation and Perturbative Quantum Chromodynamic Constraint
Shao-Peng Tang, Yong-Jia Huang, Ming-Zhe Han +1
Very recently, it has been shown that there is an upper bound on the squared sound speed of nuclear matter from the transport, which reads . In this work, w…
Mass and radius of the most massive neutron star: The probe of the equation of state and perturbative QCD
Shao-Peng Tang, Ming-Zhe Han, Yong-Jia Huang +2
Recently, an association of GW190425 and FRB 20190425A had been claimed and a highly magnetized neutron star (NS) remnant was speculated. Given the -h delay of the occurr…
Maximum gravitational mass inferred at about precision with multimessenger data of neutron stars
Yi-Zhong Fan, Ming-Zhe Han, Jin-Liang Jiang +2
The maximal gravitational mass of nonrotating neutron stars () is one of the key parameters of compact objects and only loose bounds can be set based on the first prin…
Plausible presence of new state in neutron stars with masses above
Ming-Zhe Han, Yong-Jia Huang, Shao-Peng Tang +1
We investigate the neutron star (NS) equation of state (EOS) by incorporating multi-messenger data of GW170817, PSR J0030+0451, PSR J0740+6620, and state-of-the-art theoretical pro…
Nonparametric Representation of Neutron Star Equation of State Using Variational Autoencoder
Ming-Zhe Han, Shao-Peng Tang, Yi-Zhong Fan
We introduce a new nonparametric representation of the neutron star (NS) equation of state (EoS) by using the variational autoencoder (VAE). As a deep neural network, the VAE is fr…
Black Hole Mass Function of Coalescing Binary Black Hole Systems: Is There a Pulsational Pair Instability Mass Cutoff?
Yuan-Zhu Wang, Shao-Peng Tang, Yun-Feng Liang +5
We analyze the LIGO/Virgo GWTC-2 catalog to study the primary mass distribution of the merging black holes. We perform hierarchical Bayesian analysis, and examine whether the mass…

The discovery of gravitational waves from compact objects coalescence opens a brand-new window to observe the universe. With more events being detected in the future, statistical e…
Is GW190425 consistent with being a neutron starblack hole merger?
Ming-Zhe Han, Shao-Peng Tang, Yi-Ming Hu +5
GW190425 is the second neutron star merger event detected by the Advanced LIGO/Virgo detectors. If interpreted as a double neutron star merger, the total gravitational mass is subs…
The roles of individual advanced LIGO detectors on revealing the neutron star properties
