Smoking Gun Evidence for Magnetar Engine in Long-Duration Gamma-Ray Burst 23030307A
GRB 230307A, despite its long duration, likely originates from a compact star merger and provides the first direct observational evidence of a magnetar central engine powering a gamma-ray burst.
A Unified Model of Kilonovae and Gamma-Ray Bursts in Binary Mergers Suggests Neutron Stars Power Short Gamma-Ray Bursts
Long-duration gamma-ray bursts (lbGRBs) are powered by black holes with massive accretion disks, while short-duration gamma-ray bursts (sbGRBs) are likely powered by long-lived hypermassive neutron stars (HMNSs), as evidenced by the distinct properties of their associated kilonovae.
與緻密雙星合併相關的伽瑪射線暴的發生率和噴流角度
本文探討了伽瑪射線暴 (GRB) 的發生率和噴流角度，特別關注那些與緻密雙星合併（例如雙中子星和中子星-黑洞合併）相關的伽瑪射線暴，並利用機器學習技術分析了費米/GBM 和 Swift/BAT 觀測到的 GRB 光變曲線，根據其特性將其分為不同的群集，並據此估算了與 BNS 和 NSBH 相關的 GRB 發生率，並將其與 LIGO-Virgo-Kagra (LVK) 合作組織估計的 BNS 和 NSBH 發生率進行比較，以限制 GRB 噴流的指向性。
컴팩트 바이너리 병합과 관련된 GRB의 비율 및 빔 각도 추정: 페르미/GBM 및 스위프트/BAT 데이터 분석
본 논문에서는 장기간 및 단기간 감마선 폭발(GRB)을 이원 중성자별(BNS) 및 중성자별-블랙홀(NSBH) 병합과 같은 컴팩트 바이너리 병합과 연결하고, 페르미/GBM 및 스위프트/BAT 관측을 사용하여 이러한 GRB의 비율과 빔 각도를 제한합니다.
伽瑪射線暴餘輝的 X 射線再增亮現象：來自中心引擎活動的可能跡象
長時間伽瑪射線暴 (GRB) 的 X 射線餘輝中出現的早期和晚期增亮現象，可能是由新生磁星的回落吸積或黑洞的回落吸積引起的。
X線吸収による、光学的に暗い高赤方偏移GRBの密度とイオン化プロファイルの調査
ガンマ線バースト（GRB）のX線吸収量の赤方偏移に伴う増加は、高赤方偏移環境におけるGRBの祖星の質量が大きく、ガス柱密度が高いことを示唆している。
The Density and Ionization Profile of Optically Dark and High Redshift Gamma-Ray Bursts (GRBs) as Measured by X-ray Absorption
The X-ray column density (NHX) of gamma-ray bursts (GRBs) increases with redshift, suggesting that GRB progenitors at higher redshifts are more massive and exist in environments with higher gas column densities.
감마선 폭발 GRB221009A의 기원에 대한 논란: 거대 SGR인가?
GRB221009A는 기존의 장시간 감마선 폭발(GRB) 모델로 설명하기 어려운 특징들을 보이며, 오히려 거대 SGR일 가능성이 높다는 주장을 제시한다.
The Galactic Origin of GRB221009A: Evidence Against a Cosmological Source
GRB221009A, despite being initially classified as a cosmological gamma-ray burst, exhibits several characteristics inconsistent with this origin, suggesting it is instead a giant SGR (soft gamma repeater) located within the Milky Way galaxy.
Direct Evidence for a Preburst Phase in Gamma-Ray Bursts: Observations from GRB 221009A
Analysis of GRB 221009A data from FGST and LHAASO provides direct evidence for a preburst phase in gamma-ray bursts, characterized by the emission of GeV and TeV photons preceding the detection of lower-energy photons.
