Unveiling the Nature of Superorbital Modulation of SMC X-1 using NinjaSat
Chin-Ping Hu, Naoyuki Ota, Takuya Takahashi +13
We report a long-term, high-cadence timing and spectral observation of the X-ray pulsar SMC X-1 using NinjaSat, a 6U CubeSat in low-Earth orbit, covering nearly a full superorbital…
Return of the Clocked Burster: Exceptionally Short Recurrence Time in GS 1826-238
Tomoshi Takeda, Toru Tamagawa, Teruaki Enoto +15
We report the discovery of an exceptionally short burst recurrence time in the well-known clocked burster GS 1826238, observed with the CubeSat X-ray observatory NinjaSat. In 20…
A simple, flexible method for timing cross-calibration of space missions
Matteo Bachetti, Yukikatsu Terada, Megumi Shidatsu +25
The timing (cross-)calibration of astronomical instruments is often done by comparing pulsar times-of-arrival (TOAs) to a reference timing model. In high-energy astronomy, the choi…
Thermonuclear superburst of MAXI J1752457 observed with NinjaSat and MAXI
Amira Aoyama, Teruaki Enoto, Takuya Takahashi +17
An uncatalogued bright X-ray transient was detected with MAXI on November 9, 2024, named MAXI J1752457. The NinjaSat X-ray observatory promptly observed the source from November…
