We investigate the nature of the unidentified very-high-energy (VHE) gamma-ray object, HESS J1832-093, in a multi-wavelength context. Based on X-ray variability and spectral index ($\Gamma_X\sim\,1.5$), and its broad-band spectrum (which was remarkably similar to HESS J0632+057, a confirmed gamma-ray binary), HESS J1832-093 has been considered to be a strong gamma-ray binary candidate in previous works. In this work, we provide further evidence for this scenario. We obtained a spectrum of its IR counterpart using Gemini/Flamingo, finding absorption lines that are usually seen in massive stars, in particular O stars. We also obtained a rather steep ATCA spectrum ($\alpha=-1.18^{+1.04}_{-0.88}$) which prefers a gamma-ray binary over an AGN scenario. Based on spatial-spectral analysis and variability search, we found that 4FGL J1832.9-0913 is possible to be associated with SNR G22.7-0.2 rather than with HESS J1832-093 only.

γ 射线二进制候选 HESS J1832-093 的多波长研究

我们在多波长环境中研究了身份不明的超高能 (VHE) 伽马射线物体 HESS J1832-093 的性质。基于 X 射线变异性和光谱指数 ($\Gamma_X\sim\,1.5$) 及其宽带光谱（与 HESS J0632+057 非常相似，已确认的伽马射线二进制），HESS J1832-093在以前的工作中被认为是强伽马射线二元候选者。在这项工作中，我们为这种情况提供了进一步的证据。我们使用 Gemini/Flamingo 获得了其 IR 对应物的光谱，找到了通常在大质量恒星中看到的吸收线，尤其是 O 型恒星。我们还获得了相当陡峭的 ATCA 光谱（$\alpha=-1.18^{+1.04}_{-0.88}$），它更喜欢伽马射线二进制而不是 AGN 场景。基于空间光谱分析和变异性搜索，我们发现 4FGL J1832.
