The Wide Field X-ray Telescope (WFXT) is a proposed mission concept with a high survey speed, due to the combination of large field of view (FOV), effective area and sharp PSF across the whole FOV. A mission such as WFXT will detect a large number of variable and transient X-ray sources during its operating lifetime. We present estimates of the WFXT capabilities in the time domain, allowing to study variability of thousand of AGNs with significant detail, as well as to constrain the rates and properties of hundreds of X-ray Flashes/faint GRBs, Tidal Disruption Events, ULXs, Type-I bursts etc. The planned WFXT extragalactic surveys would thus allow to trace variable and transient X-ray populations over cosmological volumes.

Abstract
The Wide Field X-ray Telescope (WFXT) is a proposed mission concept with a high survey speed, due to the combination of large field of view (FOV), effective area and sharp PSF across the whole FOV. A mission such as WFXT will detect a large number of variable and transient X-ray sources during its operating lifetime. We present estimates of the WFXT capabilities in the time domain, allowing to study variability of thousand of AGNs with significant detail, as well as to constrain the rates and properties of hundreds of X-ray Flashes/faint GRBs, Tidal Disruption Events, ULXs, Type-I bursts etc. The planned WFXT extragalactic surveys would thus allow to trace variable and transient X-ray populations over cosmological volumes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
