Generating observation guided ensembles for data assimilation with denoising diffusion probabilistic model
Yuuichi Asahi, Yuta Hasegawa, Naoyuki Onodera +3
This paper presents an ensemble data assimilation method using the pseudo ensembles generated by denoising diffusion probabilistic model. Since the model is trained against noisy a…
BOTAN: BOnd TArgeting Network for prediction of slow glassy dynamics by machine learning relative motion
Hayato Shiba, Masatoshi Hanai, Toyotaro Suzumura +1
Recent developments in machine learning have enabled accurate predictions of the dynamics of slow structural relaxation in glass-forming systems. However, existing machine-learning…
GPU-accelerated Image Reduction Pipeline
Masafumi Niwano, Katsuhiro L. Murata, Ryo Adachi +6
We developed a high-speed image reduction pipeline using Graphics Processing Units (GPUs) as hardware accelerators. Astronomers desire detecting EM counterpart of gravitational-wav…
Spectral Lag Relations in GRB Pulses Detected with HETE-2
M. Arimoto, N. Kawai, K. Asano +36
Using a pulse-fit method, we investigate the spectral lags between the traditional gamma-ray band (50-400 keV) and the X-ray band (6-25 keV) for 8 GRBs with known redshifts (GRB 01…
Multiple Component Analysis of Time Resolved Spectra of GRB041006: A Clue to the Nature of Underlying Soft Component of GRBs
Yuji Shirasaki, Atsumasa Yoshida, Nobuyuki Kawai +30
GRB 041006 was detected by HETE-2 at 12:18:08 UT on 06 October 2004. This GRB displays a soft X-ray emission, a precursor before the onset of the main event, and also a soft X-ray…
Spectral evolution of GRB 060904A observed with Swift and Suzaku -- Possibility of Inefficient Electron Acceleration
Daisuke Yonetoku, Sachiko Tanabe, Toshio Murakami +39
We observed an X-ray afterglow of GRB 060904A with the Swift and Suzaku satellites. We found rapid spectral softening during both the prompt tail phase and the decline phase of an…
