With its unprecedented sensitivity and spatial resolution, the James Webb Space Telescope (JWST) has opened a new window for time-domain discoveries in the infrared. Here we report observations in the only field that has received four epochs (spanning 126 days) of JWST NIRCam observations in Cycle 1. This field is towards MACS J0416.1-2403, which is a rich galaxy cluster at redshift z=0.4 and is one of the Hubble Frontier Fields. We have discovered 14 transients from these data. Twelve of these transients happened in three galaxies (with z=0.94, 1.01, and 2.091) crossing a lensing caustic of the cluster,and these transients are highly magnified by gravitational lensing. These 12 transients are likely of similar nature to those previously reported based on the Hubble Space Telescope (HST) data in this field, i.e., individual stars in the highly magnified arcs. However, these twelve could not have been found by HST because they are too red and too faint. The other two transients are associated with background galaxies (z=2.205 and 0.7093) that are only moderately magnified, and they are likely supernovae. They indicate a de-magnified supernova surface density, when monitored at a time cadence of a few months to a ~3--4 micron survey limit of AB ~ 28.5 mag, of ~0.5 per sq. arcmin integrated to z ~ 2. This survey depth is beyond the capability of HST but can be easily reached by JWST.

Two lensed star candidates at $z\simeq4.8$ behind the galaxy cluster MACS J0647.7+7015
我们报道了在最近的多波段詹姆斯·韦伯太空望远镜(JWST)近红外摄像机观测中,在星系团MACS J0647.7+7015后面发现了两个极度放大的透镜状恒星候选者。候选者出现在先前已知的、横跨临界曲线的$z_{phot}\simeq4.8$脱落巨弧中。候选者位于预期的临界曲线位置附近,但在另一边缺乏清晰的反像,这表明它们可能是正在经历焦散交叉的恒星。我们提出了修订后的透镜模型的集群,包括多成像星系新发现的JWST数据,并使用它们来估计至少$\gtrsim90$和$\gtrsim50$在两个候选人的位置,分别的背景宏观放大率。有了这些值,我们期望两个候选恒星的$10^4-10^5$的有效的、焦散性交叉放大率。这两个候选人的光谱能量分布(SED)匹配以及光谱的B-型恒星的最佳拟合表面温度分别为$\sim10,000$ K和$\sim12,000$ K,我们表明,这样的恒星质量$\gtrsim20$ M $_{\odot}$和$\gtrsim50$ M $_{\odot}$,分别可以成为足够的放大被观察。我们简要地讨论了其他的解释,并得出结论,这些可能是透镜星,但也承认,放大较小的候选人可能是或居住在星团。这些恒星候选者构成了继$z_{phot}\simeq6.2$的埃伦德尔之后,迄今为止第二高红移的例子,进一步建立了利用JWST研究极度放大恒星到高红移的潜力。包括近红外光谱观测在内的计划…
