标题： A new strategy to select candidate blazars for VHE observation

摘要： 一种新的策略，用于选择适用于超高能（VHE）观测的候选耀变体，该策略能够从全天区编目（排除银河系平面附近的一条狭窄区域）的GeV明亮耀变体中提供一个固有完整的样本。该策略基于从被GeV探测到的耀变体样本中选择候选VHE耀变体，即费米伽马射线空间望远镜（FGST）的LAT明亮活动星系核样本（LBAS）。VHE波段的本征谱是基于FGST测量的GeV谱的外推来估计的。这是对由于宇宙背景光（EBL）在紫外到中红外波段不可避免的消光进行修正后的结果。根据积分流量排序的可观测谱被用来提取适合用成像大气切连科夫望远镜（IACTs）进行VHE波段观测的候选天体。预测结果通过已知的VHE耀变体样本进行了交叉验证。 显示英文摘要

摘要： A new strategy to select candidate blazars for VHE observations, that gives an inherently complete sample from an all-sky compilation (excluding a narrow region around the galactic plane) of GeV-bright blazars is presented. The strategy is based on selecting candidate VHE blazars from a GeV-detected blazar sample, namely the LAT-bright-AGN-sample (LBAS) of the Fermi Gamma-ray Space Telescope (FGST). The intrinsic spectra in the VHE regime is estimated based on the extrapolation of the GeV spectra measured with FGST. This is corrected for the unavoidable extinction due to the Extragalactic Background Light (EBL) in the UV to mid-IR. The resulting observable spectra ranked by the integrated flux is used to extract candidates for observations in the VHE regime with Imaging Atmospheric Cherenkov Telescopes (IACTs). The predictions are cross-checked using the sample of known VHE blazars.
