Abstract

Fast X-ray transients (FXTs) are singular, short bursts in soft X-rays (~0.3–10 keV) that last from minutes to hours. Their origin remains unclear, and they have been associated with various progenitor mechanisms, including long-duration gamma-ray burst association, the tidal disruption of a white dwarf by an intermediate-mass black hole, a magnetar formed as the aftermath of a binary neutron star merger whose spin-down powers the burst, and a core-collapse supernova shock breakout. The newly launched X-ray survey mission, Einstein Probe (EP), is revolutionising the field by enabling the discovery and prompt follow-up of FXTs, effectively doubling the number of known extragalactic events. In my talk, I will discuss our ongoing search for multiwavelength counterparts — particularly at optical and radio wavelengths — of FXTs discovered by EP, and their role in characterising the nature of these transients.
