Recently, the radius of neutron star (NS) PSR $\mathrm{J}0740+6620$ was measured by Neutron Star Interior Composition Explorer (NICER), and an updated measurement skin thickness $^{208}\mathrm{Pb}$ (${R}_{\mathrm{skin}}^{208}$) reported PREX-II experiment. These new measurements can help us better understand unknown equation state (EOS) dense matter. In this work, we adopt a hybrid parameteriza...

GS-9451 is a selective hepatitis C virus (HCV) NS3 protease inhibitor in development for the treatment of genotype 1 (GT1) HCV infection. Key preclinical properties of GS-9451, including in vitro antiviral activity, selectivity, cross-resistance, and combination activity, as well as pharmacokinetic properties, were determined. In multiple GT1a and GT1b replicon cell lines, GS-9451 had mean 50% ...

The special point is a feature unique to models of hybrid neutron stars. It represents location on their mass--radius sequences that insensitive the phase transition density. We consider stars with core deconfined quark matter obeys constant--sound--speed (CSS) equation state model and provide fit formula for coordinates as functions squared sound speed ($c_s^2$) pressure scale ($A$) parameters...

We explore the implications of recent radius determination PSR J0740+6620 by NICER experiment combined with neutron skin measurement PREX-II and associated inference slope symmetry energy, for structure hybrid stars a strong first-order phase transition from nucleonic to quark matter. combine covariant density-functional equation state (EOS) constant-speed-of-sound EOS show that tidal deformabi...

The properties of hadron-quark hybrid stars are studied when the quark phase is described in terms a local SU(3) Nambu-Jona-Lasinio (NJL) model taking into account contribution vector and axial-vector interaction between quarks, hadronic phase, relativistic mean field (RMF) model. For different values coupling constant GV, equations state matter calculated parameters transition determined under...

Spectra of the zem = 3.268 quasar PKS 2126– 158 have been obtained in the range λλ4300 − 6620 Å with a resolution R ≃ 27000 and an average signal-tonoise ratio s/n ≃ 25 per resolution element. The list of the identified absorption lines is given together with their fitted column densities and Doppler widths. The modal value of the Doppler parameter distribution for the Lyα lines is ≃ 25 km s. T...

Abstract The measurement of the macroscopic properties a neutron star, whether in binary or an isolated system, provides us with key opportunity to place stringent constraint on its equation state. In this paper, we perform Bayesian model selection wide variety star equations state using multi-messenger observations. particular, (i) use mass and tidal deformability measurements from two merger ...

We study a family of equations state (EOS) for hybrid neutron star matter. The EOS are obtained by Maxwell construction the first-order phase transition between hadronic described relativistic density-functional ``DD2'' class with excluded volume effects and deconfined quark matter modeled an instantaneous nonlocal version Nambu--Jona-Lasinio model in $\text{SU}{(2)}_{f}$ vector interactions co...

The recently developed resummation technique known as {\it renormalization group optimized perturbation theory} (RGOPT) is employed in the evaluation of EoS describing non-strange cold quark matter at NLO. Inspired by recent investigations, which suggest that stable can be made only up and down quarks, mass-radius relation for two flavor pure stars evaluated compared with predictions from pertu...
