LHAASOが観測した謎のダンベル状構造に対する移動パルサー風星雲モデルの適用
LHAASOが観測したダンベル状の超高エネルギーガンマ線源の起源を説明するために、移動パルサー風星雲モデルを用いたモデリングが行われたが、単一の移動パルサー風星雲では説明が難しい可能性が示唆された。
Modeling the Mysterious LHAASO Dumbbell-like Structure as a Traveling Pulsar Wind Nebula
The LHAASO-detected dumbbell-like structure, composed of three UHE gamma-ray sources, is unlikely to be explained by a single traveling pulsar wind nebula model unless the diffusion coefficient is extremely low and the pulsar possesses an unusually high proper-motion velocity.
The Formation of Long-Duration Gamma-Ray Bursts and Broad-Lined Supernovae from Close Binary Stars with Black Hole Engines
Close binary star systems with black hole accretion disk engines offer a compelling explanation for the formation of long-duration gamma-ray bursts (lGRBs), low-luminosity GRBs, ultra-long GRBs, and broad-lined Type Ic supernovae (Ic-BL SNe).
IRAS F01004-2237における10年ぶりの繰り返し発生する潮汐破壊現象
IRAS F01004-2237で約10年離れて2度の光学フレアが観測され、どちらも潮汐破壊現象 (TDE) である可能性が高いことが示唆された。
Two Tidal Disruption Events Observed a Decade Apart in Galaxy IRAS F01004-2237
The observation of two optical flares separated by 10.3 years in the galaxy IRAS F01004-2237 suggests the occurrence of recurring tidal disruption events (TDEs), potentially caused by repeating partial TDEs, double TDEs, or two independent TDEs.
SRG/eROSITA全天サーベイ：銀河団の数え上げによる構造形成の制限
eROSITA X線望遠鏡を用いた銀河団の観測結果から、宇宙の構造形成が標準的な宇宙論モデルの予測よりも遅い可能性が示唆された。
Newly Formed Dust Observed in the Remnant of Supernova 2005ip Using JWST/MIRI
Observations of SN 2005ip with the James Webb Space Telescope (JWST) reveal the formation of a significant amount of dust within the cold, dense shell (CDS) of the supernova remnant, providing new insights into dust production in the early universe.
GRB 170817A의 후기 잔광에서 역방향 제트 복사 검출 가능성 재고
GRB 170817A의 후기 잔광에서 역방향 제트 복사가 검출될 가능성은 낮지만, 역방향 제트의 충격 매개변수가 순방향 제트보다 높을 경우, 특히 근적외선 대역에서 JWST를 통해 검출 가능성이 높아진다.
The Multi-Messenger Signatures of a Deformed Magnetar as a Central Engine of Gamma-Ray Bursts
The electromagnetic and gravitational wave emissions observed in gamma-ray bursts can be explained by a model using a deformed, rapidly rotating magnetar as the central engine.
Constraining Primordial Black Holes with High-Energy Neutrinos: Exploring the Impact of the Memory Burden Effect
The observation of high-energy neutrinos offers a novel method for constraining the properties of primordial black holes, particularly in light of the memory burden effect, which could significantly extend their lifespan and influence their detectability.
