Description
We conducted a series of VLT/FORS2 spectroscopic observations targeting a sample of fast X-ray transients and optical counterparts discovered by the Einstein Probe during 2024A. The observed events include supernova-like transients, GRB–associated events, and other rapidly evolving extragalactic sources. These observations provide key redshift measurements and early-time spectral features that help to constrain their physical origins. Combined with multi-wavelength data from space and ground-based facilities, the results highlight the importance of prompt optical spectroscopy in revealing the nature and diversity of fast extragalactic transients detected by the Einstein Probe.
