| Abstract : | X-ray sky is highly variable with different classes of objects exhibiting different timescales of variability that links to geometry of emission and physical processes underlying the emission mechanisms. Time-resolved spectral study of these X-ray sources plays a key role in understanding the dynamics of emission and in particular, the accretion physics and geometry of accretion in in X-ray binaries and AGNs. The present X-ray spectrometers have limited FOV and operate in a pointed mode observations for short-planned durations which constraints the long-term monitoring of any X-ray source. It is crucial to study the spectro-temporal behaviour of the sources over longer timescales, like a year or more, in addition to having possible continuous monitoring of the sources with very minimal time gaps (which may arise due to orbital constraints of the spacecraft) between observations.
A Wide-Field Imager and Soft X-ray Spectrometer, which has a large FoV, will provide an excellent platform to carry out long-term spectro-temporal study of astrophysical sources. We propose a ~15 deg x 15 deg FoV Wide-Field Imager and Soft X-ray Spectrometer with micropore optics and an X-ray CCD/CMOS detector for long-term spectro-temporal studies of many X-ray sources simultaneously. The concept design of this instrument, along with detailed specifications and simulations, will be discussed in this presentation.
