论文摘要
我们介绍了有关超新星强力透镜的冬青树蛋白计划，作为超新星（SN）物理学和宇宙学的探测。我们使用四种不同的SN爆炸模型研究了微透明对早期SN IA光谱的影响，并发现在SN爆炸后的10天内休息几天内，由于微透镜引起的SN IA光谱扭曲通常可以忽略不计（$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ 1 $σ$ spread spret，$ \ flices $ \\ $ \\ $ 10％$ 10 $ 2 $ 2 $ scread）sprif spread）sprif affer sprind sprife sprind sprif spread）sprind sprif spread）sprif spread）sprif spread）。这显示了使用镜头SNE IA获得固有的早期SN光谱的巨大前景。为了证明镜头SNE IA对宇宙学的有用性，我们模拟了模拟的镜头SN IA系统的样本，这些样本有望在Rubin天文台的时空和时间（LSST）的时代具有准确而精确的时间延迟测量。在其时间延迟距离和镜头角直径距离（分别为6.6％和5％）上采用现实但保守的不确定性（分别为6.6％和5％），我们发现一个样本的20个镜头SNE IA可以限制对哈勃常数（$ h_0 $）的约束，而平面$ CDM $ CDM COSMOLAGY中的1.3％不确定。我们在开放的$λ$ CDM宇宙学中发现了对$ h_0 $的类似限制，而约束则降低到$ 3 \％$ $ w $ w $ cdm宇宙学中的$ 3 \％。我们预计，在即将到来的LSST时代，镜头将成为对SN物理和宇宙学的独立和强大的调查。
We present the HOLISMOKES programme on strong gravitational lensing of supernovae as a probe of supernova (SN) physics and cosmology. We investigate the effects of microlensing on early-phase SN Ia spectra using four different SN explosion models, and find that within 10 rest-frame days after SN explosion, distortions of SN Ia spectra due to microlensing are typically negligible ($<$1% distortion within the 1$σ$ spread, and $\lesssim$10% distortion within the 2$σ$ spread). This shows great prospects of using lensed SNe Ia to obtain intrinsic early-phase SN spectra for deciphering SN Ia progenitors. As a demonstration of the usefulness of lensed SNe Ia for cosmology, we simulate a sample of mock lensed SN Ia systems that are expected to have accurate and precise time-delay measurements in the era of the Rubin Observatory Legacy Survey of Space and Time (LSST). Adopting realistic yet conservative uncertainties on their time-delay distances and lens angular diameter distances (of 6.6% and 5%, respectively), we find that a sample of 20 lensed SNe Ia would allow a constraint on the Hubble constant ($H_0$) with 1.3% uncertainty in the flat $Λ$CDM cosmology. We find a similar constraint on $H_0$ in an open $Λ$CDM cosmology, while the constraint degrades to $3\%$ in a flat $w$CDM cosmology. We anticipate lensed SNe to be an independent and powerful probe of SN physics and cosmology in the upcoming LSST era.
