Discovery of Decimeter Radio Wave Pulses from Super Massive Black Holes in the Center Region of Our Galaxy : First Preliminary Results Oya, Hiroshi Pulses of decimeter wavelength radio waves, in the frequency bands of 1.4GHz and 1.6GHz, arriving from the center part of our Galaxy have been discovered by observations made from July 25 to August 26,2005 at Awara Space and Cosmic Radio wave Observatory of Space Communication Science and Technology in Fukui University of Technology, The identified pulse periods are 129.99, 104.55 and 52.003 sec which correspond, respectively to Gaa, Gab, and Gac that had been already detected in decameter wavelength range. Because the decameter wave pulses have been considered to be from the rotating super massive black holes, the origins of decimeter radio pulses detected in the present study can also be considered to be radiated from the same black holes in the center part of our Galaxy. 福井工業大学 2006-03-18 eng departmental bulletin paper VoR https://doi.org/10.57375/00000736 https://fut.repo.nii.ac.jp/records/742 10.57375/00000736 TF00009195 2868571 福井工業大学研究紀要. 第一部 36 221 228 https://fut.repo.nii.ac.jp/record/742/files/KJ00004437943.pdf application/pdf 637.1 kB 2023-04-12
