초고에너지 은하 확산 감마선 방출에서 미해결 펄서의 기여도는 이전 연구에서 추정했던 것보다 낮으며, 특히 은하계 외곽에서는 미미한 수준이다.
高解像度ALMA観測により、大質量原始星S255IR NIRS3を取り巻くジェットと円盤の構造が明らかになり、星形成における降着と噴出の複雑なプロセスに関する新たな知見が得られた。
This research paper presents a systematic identification of supergiant stars in the nearby galaxies M31 and M33 using spectroscopic data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 10 (DR10).
Observations from the Large High Altitude Air Shower Observatory (LHAASO) reveal ultrahigh-energy gamma-ray emissions from five microquasars, indicating that these black hole-jet systems can accelerate particles to extremely high energies, potentially contributing to Galactic cosmic rays.
Current AGN and galaxy formation models struggle to explain the unique spectral characteristics of A2744-QSO1, a compact, high-redshift galaxy observed by JWST, suggesting a need for revised understanding of early galaxy evolution.
