XRISM Spectroscopy of a Crowded Galactic Center Region. II. Narrow Emission Lines in the Black Hole Candidate MAXI J1744-294/Swift J174540.2-290037

Narrow, highly ionized X-ray emission lines in black hole low-mass X-ray binaries (BH-LMXBs) are rare and have been observed in only a few sources, during unusual, heavily obscured accretion states. We report on a detailed high-resolution spectral analysis of emission line features from the first XR...
