论文摘要
我们使用38个c iv quasar（QSO）混响映射（RM）观察结果，这些观察值涵盖了八个数量级的亮度和红移范围$ 0.001064 \ leq z \ leq z \ leq 3.368 $，以同时限制宇宙学模型和QSO radius-luminosic crominiquique cosmogicy in Six cosm oss in cosm oss in cosm oss in cosm inst rocm cosm insique in 6时间滞后测量的不对称误差栏。我们发现，$ r-l $关系参数与分析中使用的宇宙学模型无关，因此$ r-l $关系可用于标准化C IV QSO。 C IV QSO宇宙学的约束与MG II QSO的cos界限一致，使我们能够得出与当前加速的宇宙学扩展相一致的联合C IV + MG II QSO宇宙学的约束，并且与使用综合的Baryon声学振荡（Baryon Socoustive）$ sumortic uscillation（bary oscillation）和$ hubble参数（ZO）（hubble）（hubble）（hubble）（hubble）（hubble）（hubble）（hubble）（hubble）[hubble）[hubble hhubble camble）[hubble khubble camble）[hubble）[hubble khubble参数]。当使用$ H（Z）$ + BAO数据共同分析时，当前的C IV + mg II QSO数据轻度拧紧当前$ H（Z）$ + BAO数据宇宙学限制。
We use 38 C IV quasar (QSO) reverberation-mapped (RM) observations, which span eight orders of magnitude in luminosity and the redshift range $0.001064 \leq z \leq 3.368$, to simultaneously constrain cosmological-model and QSO radius-luminosity ($R-L$) relation parameters in six cosmological models, using an improved technique that more correctly accounts for the asymmetric errors bars of the time-lag measurements. We find that $R-L$ relation parameters are independent of the cosmological models used in the analysis and so the $R-L$ relation can be used to standardize the C IV QSOs. The C IV QSO cosmological constraints are consistent with those from Mg II QSOs, allowing us to derive joint C IV + Mg II QSO cosmological constraints which are consistent with currently accelerated cosmological expansion, as well as consistent with cosmological constraints derived using better-established baryon acoustic oscillation (BAO) and Hubble parameter [$H(z)$] measurements. When jointly analyzed with $H(z)$ + BAO data, current C IV + Mg II QSO data mildly tighten current $H(z)$ + BAO data cosmological constraints.
