本研究利用HAWC天文台1,910天数据在eHWC J1842-035区域发现三个源,确认HAWC J1844-034为发射175 TeV光子的扩展源,结合多波段数据拟合能谱,并确认PSR J1844-0346和SNR G28.6-0.1为潜在对应源。

摘要:

近期,由于eHWC J1842-035周围区域具有延伸至数百TeV的扩展辐射,以及作为强子加速器的潜力,伽马射线天文台对其进行了广泛研究。在本研究中,我们利用高海拔水切伦科夫(HAWC)天文台累积的1,910天数据,对eHWC J1842-035区域进行了专门的系统性源搜索。在搜索过程中,我们在该区域发现了三个源,即HAWC J1844-034、HAWC J1843-032和HAWC J1846-025。我们确认HAWC J1844-034为发射能量高达175 TeV光子的扩展源。我们计算了HAWC J1844-034的能谱,并通过与其他实验的观测结果进行比较,确认HESS J1843-033、LHAASO J1843-0338和TASG J1844-038为具有匹配起源的超高能伽马射线源。此外,我们展示并利用多波段数据拟合了强子和轻子粒子能谱。我们在附近区域识别出四个脉冲星候选体,其中由于PSR J1844-0346靠近HAWC J1844-034且符合计算的能量预算,因此被认为是最可能的候选体。我们还发现SNR G28.6-0.1是HAWC J1844-034的潜在对应源,其轻子和强子情景均具有可行性。

英文摘要:

Recently, the region surrounding eHWC J1842-035 has been studied extensively by gamma-ray observatories due to its extended emission reaching up to a few hundred TeV and potential as a hadronic accelerator. In this work, we use 1,910 days of cumulative data from the High Altitude Water Cherenkov (HAWC) observatory to carry out a dedicated systematic source search of the eHWC J1842-035 region. During the search we have found three sources in the region, namely, HAWC J1844-034, HAWC J1843-032, and HAWC J1846-025. We have identified HAWC J1844-034 as the extended source that emits photons with energies up to 175 TeV. We compute the spectrum for HAWC J1844-034 and by comparing with the observational results from other experiments, we have identified HESS J1843-033, LHAASO J1843-0338, and TASG J1844-038 as very-high-energy gamma-ray sources with a matching origin. Also, we present and use the multi-wavelength data to fit the hadronic and leptonic particle spectra. We have identified four pulsar candidates in the nearby region from which PSR J1844-0346 is found to be the most likely candidate due to its proximity to HAWC J1844-034 and the computed energy budget. We have also found SNR G28.6-0.1 as a potential counterpart source of HAWC J1844-034 for which both leptonic and hadronic scenarios are feasible.
