GRB~230812B is a bright and relatively nearby ($z =0.36$) long gamma-ray burst (GRB) that has generated significant interest in the community and has thus been observed over the entire electromagnetic spectrum. We report over 80 observations in X-ray

One month after launching Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM), a bright thermonuclear X-ray burst from 4U~0614+09, was observed on January 24, 2021. We report the time-resolved spectroscopy of the burst

M., Boynton, W., Fellows, C. W., Harshman, K. P., Enos, H., Starr, R.

Magnetars are young, highly magnetized neutron stars that produce extremely rare giant flares of gamma-rays, the most luminous astrophysical phenomena in our Galaxy. The detection of these flares from outside the Local Group of galaxies has been pred

Gamma-Ray Bursts with Extended Emission: Classifications, Energy Correlations and Radiation Properties

Autor: Zhang, X. L., Zhang, C. T., Li, X. J., S, F. F., Dong, X. F., Chang, H. Y., Zhang, Z. B.

Thanks to more and more gamma-ray bursts with measured redshift and extended emission detected by the recent space telescopes, it is urgent and possible to check whether those previous energy correlations still satisfy for the particular sample invol

Gamma-ray Emission of 60Fe and 26Al Radioactivities in our Galaxy

Autor: Wang, W., Siegert, T., Dai, Z. G., Diehl, R., Greiner, J., Heger, A., Krause, M., Lang, M., Pleintinger, M. M. M., Zhang, X. L.

The isotopes $^{60}$Fe and $^{26}$Al originate from massive stars and their supernovae, reflecting ongoing nucleosynthesis in the Galaxy. We studied the gamma-ray emission from these isotopes at characteristic energies 1173, 1332, and 1809 keV with o
