Evidence presented by Yershov, Orlov and Raikov apparently showed that the WMAP/Planck cosmic microwave background (CMB) pixel-temperatures (T) at supernovae (SNe) locations tend to increase with increasing redshift ($z$). They suggest this correlation could be caused by the Integrated Sachs-Wolfe effect and/or by some unrelated foreground emission. Here, we assess this correlation independently using Planck 2015 SMICA R2.01 data and, following Yershov et al., a sample of 2783 SNe from the Sternberg Astronomical Institute. Our analysis supports the prima facie existence of the correlation but attributes it to a composite selection bias (high CMB T $\times$ high SNe $z$) caused by the accidental alignment of seven deep survey fields with CMB hotspots. These seven fields contain 9.2 per cent of the SNe sample (256 SNe). Spearman's rank-order correlation coefficient indicates the correlation present in the whole sample ($ρ_s = 0.5$, p-value $= 6.7 \times 10^{-9}$) is insignificant for a sub-sample of the seven fields together ($ρ_s = 0.2$, p-value $= 0.2$) and entirely absent for the remainder of the SNe ($ρ_s = 0.1$, p-value $= 0.6$). We demonstrate the temperature and redshift biases of these seven deep fields, and estimate the likelihood of their falling on CMB hotspots by chance is at least $\sim$ 6.8 per cent (approximately 1 in 15). We show that a sample of 7880 SNe from the Open Supernova Catalogue exhibits the same effect and we conclude that the correlation is an accidental but not unlikely selection bias.

Observational Constraints on Visser's Cosmological Model
引力子可以被视为大质量粒子的引力理论目前已经被研究为广义相对论的现实修改，并且可以用宇宙学观测来检验。在这项工作中，我们研究的能力，最近提出的理论与大质量引力子，所谓的维瑟理论，解释测量的光度距离从联盟2汇编，最近的Ia型超新星（SNe Ia）数据集，采用当前的非相对论性物质的总密度的临界密度（$Ω_m$）的比率作为一个自由参数。我们还结合了超新星Ia数据的约束，从重子声学振荡（BAO）和CMB测量。我们发现，在允许的$Ω_m$值区间内，基于Visser理论的模型可以产生一个没有暗能量成分的加速膨胀期，但综合分析（SNe Ia + BAO + CMB）表明，该模型与$Λ$ CDM模型相比是不利的.

The Hubble constant tension: current status and future perspectives through new cosmological probes
哈勃常数（$H_0$）张力是现代宇宙学中的主要开放问题之一。这种张力是由Ia超新星（SNe Ia）+造父变星组合估算的局部$H_0$值与通过研究宇宙微波背景（CMB）辐射获得的宇宙学$H_0$之间的差异，范围从4到6 $σ$。介绍了Dainotti et al.2021（ApJ）和Dainotti et al.2022（Galvanic）中采用的方法。通过对超新星Ia的Pantheon样本进行分组划分（Scolnic et al. 2018），在每个红移有序的bin中估计了$H_0$的值，并拟合了一个随红移降低的函数。结果表明，随着红移的增加，$H_0$有减小的趋势。如果这不是由于天体物理学的偏差或Ia超新星参数的残余红移演化造成的，那么可以根据修正的引力理论来解释，例如，$f(R)$场景。我们还简要描述了高$z$探测器对哈勃常数张力的可能影响，例如伽马射线暴（GRB）和类星体（QSO），分别在Dainotti等人2022（Galvanie）和Lenart等人2022（ApJ）中报道。
