The UV photons are emitted by heating up the surrounding gas to extremely high temperatures. This makes the UV photons a very good tracer for determining Star Formation Rate in the early universe. In deep fields, the UV photons from AGNs appear the same as UV photons from young massive stars. One important aspect of this study is to separate Active Galactic Nuclei (AGNs) and Star Forming Galaxies (SFGs). To achieve this, we use multiwavelength data and photometric redshifts of the deep field. The UV data of the multiwavelength observation was taken from Ultraviolet Imaging Telescope (UVIT) aboard the AstroSat. SDSS DR18 data for optical observations, IRAC SWIRE data for infrared observations and uGMRT data for radio observations. Here, we present the latest results from the radio and UV observations of ELAIS-N1 field done with uGMRT and ASTROSAT-UVIT. We show the analysed deep field in UV observations and present the catalogue of the sources. Using the catalogue we have performed the classification of SFGs and AGNs. We also derived the Star Formation Rate (SFR) using FUV data and the global SFR by performing SED fitting. The extinction-corrected SFR is derived at FUV wavelengths. These will be compared to different SFR derived from IR and radio in future studies, preliminary results will be presented. |
