通过 JCMT 后续观测和 HerBS/PHZ 目录关联搜寻冰立方中微子对应体，发现 Shadow Blaster 等强透镜尘埃星系，支持分层搜寻策略。
AI 中文摘要
亚毫米波段为识别高能中微子的电磁对应体提供了一条互补途径，可追踪相对论性瞬变源和持续的尘埃遮蔽星系。我们展示了一项先导搜寻，将冰立方事件的 JCMT/SCUBA-2 后续观测与亮高红移尘埃系统的目录搜寻相结合。在快速观测的九个冰立方天区中，有三个天区发现了特别感兴趣的源：IC 210922A 中的 JCMT0402-0424（"Shadow Blaster"）、IC 220115A 之后的类瞬变源，以及 IC 240105A 中的两个已知耀变体。ALMA 将 Shadow Blaster 分辨为一个强引力透镜化的尘埃恒星形成星系，红移 z=2.988，具有致密富气恒星爆发核。受此结果启发，我们将冰立方定位与 Herschel 亮源（HerBS）和 Planck 高红移源候选体（PHZ）目录进行交叉匹配。在 51 个历史冰立方事件中，A_bbox,90 <= pi deg^2 的天区有四个包含至少一个 HerBS 源，而根据赤经随机打乱预期的数目为 0.723（固定阈值 p=4.18e-3）。扫描定位面积阈值得到 p_global,A=0.0135。将相同的冰立方选择应用于 PHZ，得到四个关联天区，而预期为 3.544（p=0.478）。由于聚焦的 HerBS 选择是在更广泛的探索性分析之后进行的，后者经试验校正的 p_global=0.130，因此聚焦结果具有提示性而非决定性。四个定位良好的 HerBS 天区包含六个高红移 DSFG，其表观 L_IR~10^13 L_sun。ALMA 成像和已发表的谱学揭示出致密或多分量形态、极端分子气体运动学以及可能的遮蔽核活动。这些结果支持一种分层策略：通过广域成像和目录识别明亮的亚毫米候选体，然后以高角分辨率对其进行表征，以检验致密富气量热条件和遮蔽 AGN 活动。
英文摘要
The submillimeter band offers a complementary route to identifying electromagnetic counterparts of high-energy neutrinos, tracing relativistic transients and persistent dust-obscured galaxies. We present a pilot search combining JCMT/SCUBA-2 follow-up of IceCube events with catalog searches for bright high-redshift dusty systems. Among nine rapidly observed IceCube fields, sources of particular interest were found in three: JCMT0402-0424 ("Shadow Blaster") in IC 210922A, a transient-like source following IC 220115A, and two known blazars in IC 240105A. ALMA resolved the Shadow Blaster into a strongly lensed dusty star-forming galaxy at z=2.988 with a compact gas-rich starburst core. Motivated by this result, we cross-matched IceCube localizations with the Herschel Bright Sources (HerBS) and Planck High-Redshift Source Candidate (PHZ) catalogs. Among 51 historical IceCube events with A_bbox,90 <= pi deg^2, four fields contain at least one HerBS source, compared with 0.723 expected from right-ascension scrambling (fixed-cut p=4.18e-3). Scanning the localization-area threshold gives p_global,A=0.0135. Applying the same IceCube selection to PHZ gives four associated fields versus 3.544 expected (p=0.478). Because the focused HerBS selection followed a broader exploratory analysis with trials-corrected p_global=0.130, the focused result is suggestive rather than definitive. The four well-localized HerBS fields contain six high-redshift DSFGs with apparent L_IR~10^13 L_sun. ALMA imaging and published spectroscopy reveal compact or multiple-component morphologies, extreme molecular-gas kinematics, and possible obscured nuclear activity. These results support a hierarchical strategy: identify luminous submillimeter candidates through wide-field imaging and catalogs, then characterize them at high angular resolution to test for compact gas-rich calorimetric conditions and obscured AGN activity.
