抄録/ポイント： カナダ水素強度マッピング実験(CHIME)/FRB実験は,その感度と広い視野のため,数千の高速無線バースト(FRB)を検出した。しかし,その低い角分解能は,そのホスト銀河への局在化事象からそれを防ぐ。CHIME/FRBからのFRB検出によって引き起こされる非常に長いベースライン干渉法(VLBI)は,非反復事象のための局在化の課題を解決するであろう。オンタリオカナダに位置するAlgonquinラジオ観測所で10mのラジオディッシュを用いて,理論的λ/D≦30masのVLBI実験のためのテストベッドを開発した。10mシステムの概観を提供し,その改修,データ取得,および,電離層からの分散遅延と局在化のために使用する幾何学的遅延を同時に推定するフリンジフィッティングのための手順を述べた。Crab pulsarからの単一パルスを用いて,システムおよび位置決め手順を検証し,FRB事象を参照するコヒーレント遅延に対して重要なサイト間のクロック安定性を解析した。200masの局在化が,現在のシステム(単一ベースライン)の性能で可能であることを見出した。さらに,幾何学的および電離層遅延の両方を同時に測定するための不十分な信号または制限された広帯域を有するソースに対して,2つのサイトの間の微分電離層寄与を,1×10-8pccm-3の精度に測定しなければならないことを示し,400~800MHzバンドにおける検出から妥当な局在化を提供した。最後に,CHIMEとAlgonquin10m望遠鏡において同時に観測されたFRBの検出,この長いベースラインにおける最初の非反復FRBを示した。このプロジェクトは,CHIME/FRBアウトトリガープロジェクトのためのテストベッドとして役立つ。Please refer to the publisher for the copyright holders.
