Suzaku diagnostics of the energetics in the lobes of the giant radio galaxy 3C 35
Naoki Isobe, Hiromi Seta, Poshak Gandhi +1
The Suzaku observation of a giant radio galaxy 3C 35 revealed faint extended X-ray emission, associated with its radio lobes and/or host galaxy. After careful subtraction of the X-…
Complex sequencing rules of birdsong can be explained by simple hidden Markov processes
Kentaro Katahira, Kenta Suzuki, Kazuo Okanoya +1
Complex sequencing rules observed in birdsongs provide an opportunity to investigate the neural mechanism for generating complex sequential behaviors. To relate the findings from s…
Spectral Cross-calibration of the Konus-Wind, the Suzaku/WAM, and the Swift/BAT Data using Gamma-Ray Bursts
T. Sakamoto, V. Pal'shin, K. Yamaoka +20
We report on the spectral cross-calibration results of the Konus-Wind, the Suzaku/WAM, and the Swift/BAT instruments using simultaneously observed gamma-ray bursts (GRBs). This is…
Search for Gravitational Wave Bursts from Six Magnetars
J. Abadie, B. P. Abbott, R. Abbott +765
Soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are thought to be magnetars: neutron stars powered by extreme magnetic fields. These rare objects are characterized b…
WIDGET: System Performance and GRB Prompt Optical Observations
Yuji Urata, Makoto S. Tashiro, Toru Tamagawa +11
The WIDeField telescope for Gamma-ray burst Early Timing (WIDGET) is used for a fully automated, ultra-wide-field survey aimed at detecting the prompt optical emission associated w…
Soft Gamma-ray Detector for the ASTRO-H Mission
Hiroyasu Tajima, Roger Blandford, Teruaki Enoto +26
ASTRO-H is the next generation JAXA X-ray satellite, intended to carry instruments with broad energy coverage and exquisite energy resolution. The Soft Gamma-ray Detector (SGD) is…
