| dc.description.abstract | XRISM/Xtend Transient Search (XTS) detected an X-ray flare from an X-ray source XRISM J1733-2440 on 2025-03-25 TT. The source position is determined to be (R.A., Dec.) = (263.262, -24.588), with a systematic error of ∼ 40 arcsec. A plausible counterpart is X-ray sources 1WGA J1733.0-2435, 4XMMs J173302.1-243510, or 2RXP J173302.0-243510. They are located within 15 arcsec from the position of XRISM J1733-2440. The flare reached its peak on 2025-03-25 at ∼ 15:19. The flare exponentially decayed in 8 × 10³ sec. The flux at the flare peak is estimated as 6 × 10⁻¹³ erg s⁻¹ cm⁻² (0.4 – 10.0 keV). A systematic error of roughly 20% should be added to the statistical error. We estimated the systematic error for the source position from the separations between the detected sources with the corresponding counterparts in the same field of view. | |
