The compact neutron star in 4U 1746-37 revisited: Reassessing the mass and radius
Kwang Hyun Sung, Myungkuk Kim, Young-Min Kim +2
A recent analysis of photospheric radius expansion X-ray bursts from the low-mass X-ray binary 4U 1746-37 reported unusually small mass and radius estimates for the neutron star, s…
Effects of pair freeze-out on photon distributions in BBN epoch
Jeongyoon Choi, Dukjae Jang, Youngshin Kwon +5
We investigate the evolution of non-extensivity in the photon distribution during the Big Bang Nucleosynthesis (BBN) epoch using Tsallis statistics. Assuming a minimal deviation fr…
Measuring Masses and Radii of Neutron Stars in Low-Mass X-ray Binaries: Effects of Atmospheric Composition and Touchdown Radius
Myungkuk Kim, Young-Min Kim, Kwang Hyun Sung +2
Methods. We use both a Monte Carlo (MC) sampling and a Bayesian analysis to find the effects of the photospheric composition and the touchdown radius. We apply these two methods to…
Constraining the density dependence of the symmetry energy with nuclear data and astronomical observations in the KIDS framework
Hana Gil, Young-Min Kim, Panagiota Papakonstantinou +1
The KIDS framework for the nuclear equation of state (EoS) and energy density functional (EDF) offers the possibility to explore symmetry-energy (SE) parameters such as J (value at…
Extended parity doublet model with a new transport code
Myungkuk Kim, Sangyong Jeon, Young-Min Kim +2
A new transport code "DaeJeon Boltzmann-Uehling-Uhlenbeck (DJBUU)" had been developed and enables to describe the dynamics of heavy-ion collisions in low-energy region. To confirm…
Neutron star equation of state and tidal deformability with nuclear energy density functionals
Young-Min Kim, Kyujin Kwak, Chang Ho Hyun +2
Neutron star is the ultimate testing place for the physics of dense nuclear matter. Before the detection of gravitational waves from the merger of binary neutron stars, various nuc…
Investigation of X-ray timing and spectral properties of ESO 243-49 HLX-1 with long-term Swift Monitoring
Lupin Chun-Che Lin, Chin-Ping Hu, Kwan-Lok Li +5
The long-term Swift monitoring of ESO 243-49 HLX-1 provides an opportunity to investigate the detailed timing and spectral behaviour of this hyper-luminous X-ray source. Swift has…
Analysis of nuclear structure in a converging expansion scheme
Hana Gil, Young-Min Kim, Chang Ho Hyun +2
In the framework of the KIDS generalized energy density functional (EDF), the nuclear equation of state (EoS) is expressed as an expansion in powers of the Fermi momentum or the cu…
Measurement of Tidal Deformability in the Gravitational Wave Parameter Estimation for Nonspinning Binary Neutron Star Mergers
Yong-Beom Choi, Hee-Suk Cho, Chang-Hwan Lee +1
One of the main targets for ground-based gravitational wave (GW) detectors such as Advanced LIGO (Laser Interferometer Gravitational wave Observatory) and Virgo is coalescences of…
Tidal Deformability of Neutron Stars with Realistic Nuclear Energy Density Functionals
Young-Min Kim, Yeunhwan Lim, Kyujin Kwak +2
We investigate the constraints on the mass and radius of neutron stars by considering the tidal deformability in the merge of neutron star binaries. In order to extract the most re…
Direct Photon Elliptic Flow at BNL Relativistic Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC)
Young-Min Kim, Chang-Hwan Lee, Derek Teaney +1
We use an event-by-event hydrodynamical description of the heavy-ion collision process with Glauber initial conditions to calculate the thermal emission of photons. The photon rate…
