In this paper, we investigate the benefits of teaming up data from radio to far- 1 infrared (FIR) regime for characterization Dusty Star-Forming Galaxies (DSFGs). These galaxies 2 are thought be star-forming progenitors local massive quiescent galaxies, and play a pivotal 3 role in reconstruction cosmic star formation rate density high redshift. Due their 4 dust-enshrouded nature, DSFGs often invisible near-infrared/Optical/UV bands. Therefore, 5 they necessitate observations at longer wavelengths, primarily FIR, where dust emission occurs, 6 radio, which is not affected by absorption. Combining these two spectral windows 7 makes it possible characterize even dustiest objects, enabling retrieval information about 8 age, temperature, star-formation status, facilitates differentiation between 9 various galaxy populations that evolve throughout history. Despite detection faint 10 sources being challenging task, study demonstrates an effective strategy build statistically 11 relevant samples would reaching deep sensitivities band, restricted 12 smaller areas, then combining with FIR/submm data. Additionally, 13 paper quantifies improvement Spectral Energy Distribution (SED) 14 incorporating ALMA band measurements, particular, its upgraded status thanks 15 anticipated Wideband Sensitivity Upgrade.
