摘要
过去我们主要依赖以 为中心的波形红外观测来了解星际尘埃星形成。然而，这些观测忽略了尘埃覆盖且质量巨大的源体，导致对早期星系形成的统计不完整。最近，红外数据来自 Spitzer 和詹姆斯·韦伯太空站（JWST）揭示了在 3-6 范围内一群极红色天体的隐藏 population。利用 Euclid 深场（EDFs）覆盖约 60 平方度的成像，以及周边 Spitzer 观测的重叠区域，我们识别出 27000 个 的极红色天体（称为 HIEROs），其下限为 IRAC2 = AB 的 完整度。经视觉检查筛除杂散和光度数据不佳的天体后，我们最终得到 3900 个候选样本。我们从 SED 拟合工具 CIGALE 中获取这些天体的物理参数估计。我们的结果确认，HIERO 星系可能位于 星系质量函数的高质量端，其中一些星系质量可达极端值 ()，并表现出极高的尘埃衰减 ()。然而，我们认为 的星系质量估计不可靠，倾向于较低的红移解。SED 拟合工具在刻画这些天体方面面临的挑战凸显了需要进一步研究的必要性，这些研究将纳入更短波长和光谱数据。Euclid 光谱将有助于消除混淆并更好地约束这些天体的物理属性。鉴于这一 population 的极端特性，准确描述这些源体对于理解星系演化至关重要。本工作表明，Euclid 有望提供 稀有、质量巨大、尘埃遮蔽星系的统计样本，这些星系将成为 JWST、ALMA 和 ELT 的热门目标。
