摘要

哈勃张力(Hubble Tension)是指哈勃常数(H0)的直接测量值与间接测量值之间大于 5σ 的差异,这种现象已经持续了十年之久,促使人们对用于推断 H0 的路径进行严格审查。比较一组具有不同标准烛光(如红巨枝(TRGB)顶端和仙王座变星)的星系的独立推导距离,可以检验距离阶梯中段的系统性。I 波段是测量 TRGB 的首选滤光片,因为它与颜色恒定,这是对恒星模型支持的年龄和金属性群体差异敏感度较低的结果。我们利用詹姆斯-韦伯太空望远镜(JWST)的观测结果,以 maser 宿主 NGC 4258 为几何锚,测量了 28 Mpc 范围内 10 个 Ia 型超新星(SNe Ia)的 8 个宿主的 I 波段(F090W 与 F090W - F150W)TRGB 距离:NGC 1448、NGC 1559、NGC 2525、NGC 3370、NGC 3447、NGC 5584、NGC 5643 和 NGC 5861。我们将这些数据与哈勃太空望远镜(HST)基于仙王座的相对距离模量对相同星系和锚进行了比较。我们没有发现它们的加权平均值(0.01 ± 0.04 (stat) ± 0.04 (sys) mag)之间存在差异。我们制作了 14 种 TRGB 分析变体,改变了用于测量尖端的平滑水平和颜色范围,以探究它们的影响。对某些宿主来说,这改变了最强峰值的识别,但这对样本平均差异的影响很小,产生了一个 0.00-0.02 兆的完整范围,在 1σ 时都是一致的,没有差异。这一结果与过去使用 HST 对 I 波段 TRGB 和仙王座进行比较的结果相吻合。用 JWST 观测到的 SNe 和锚样本太小,无法得到与 HST 的 42 个 SNe Ia 和 4 个锚样本具有竞争力的 H0 测量值;不过,它们已经为 HST 的距离阶梯测量提供了重要的系统性交叉检验。

Tip of the Red Giant Branch Distances with JWST. II. I-band Measurements in a Sample of Hosts of 10 Type Ia Supernova Match HST Cepheids
The Hubble Tension, a >5σ discrepancy between direct and indirect measurements of the Hubble constant (H0), has persisted for a decade and motivated intense scrutiny of the paths used to infer H0. Comparing independently derived distances for a set of galaxies with different standard candles, such as the tip of the red giant branch (TRGB) and Cepheid variables, can test for systematics in the middle rung of the distance ladder. The I band is the preferred filter for measuring the TRGB due to constancy with color, a result of low sensitivity to population differences in age and metallicity supported by stellar models. We use James Webb Space Telescope (JWST) observations with the maser host NGC 4258 as our geometric anchor to measure I-band (F090W versus F090W − F150W) TRGB distances to eight hosts of 10 Type Ia supernovae (SNe Ia) within 28 Mpc: NGC 1448, NGC 1559, NGC 2525, NGC 3370, NGC 3447, NGC 5584, NGC 5643, and NGC 5861. We compare these with Hubble Space Telescope (HST) Cepheid-based relative distance moduli for the same galaxies and anchor. We find no evidence of a difference between their weighted means, 0.01 ± 0.04 (stat) ± 0.04 (sys) mag. We produce 14 variants of the TRGB analysis, altering the smoothing level and color range used to measure the tips to explore their impact. For some hosts, this changes the identification of the strongest peak, but this causes little change to the sample mean difference, producing a full range of 0.00–0.02 mag, all consistent at 1σ with no difference. The result matches past comparisons of I-band TRGB and Cepheids when both use HST. SNe and anchor samples observed with JWST are too small to yield a measure of H0 that is competitive with the HST sample of 42 SNe Ia and 4 anchors; however, they already provide a vital systematic cross-check to HST measurements of the distance ladder.
