Dust Emission and Star Formation Activities of High Redshift Weak Emission Line Quasars

We present the work using the high-quality optically-selected quasar catalogue from the Sloan Digital Sky Survey (SDSS) to select a large sample of Weak Emission Line Quasars (WELQs). The Equivalent Widths (EWs) of their emission lines are on the weaker end of the spectrum for Active Galactic Nuclei (AGNs). Yet, their bolometric luminosity distribution is similar to that of Normal Emission Line Quasars (NELQs). By integrating data from multiple wavelength bands, including the ultraviolet data from the Galaxy Evolution Explorer (GALEX), the near-infrared data from the United Kingdom Infrared Telescope Deep Sky Survey (UKIDSS), the mid-infrared data from the Wide-field Infrared Survey Explorer (WISE), and the far-infrared images from the Herschel Space Telescope, we conducted a comprehensive study on the Spectral Energy Distribution (SED) of WELQs across ultraviolet, optical, near-infrared, mid-infrared, and far-infrared bands. Our research indicates that within the redshift range of "1
