Title: What can we learn from the deepest extragalactic radio continuum surveys?
Abstract:
Radio continuum imaging has been a key approach to trace the production of stars and the activity of supermassive black holes at redshifts 0<z<5 —a cosmic epoch marked by the dominant fraction of star formation that is obscured by dust. In recent years, our team has pushed the resolution and sensitivity limits of the Very Large Array (VLA) to obtain some of the deepest and sharpest radio continuum images ever obtained, providing unique constraints on the radio morphologies of massive star-forming galaxies at high redshifts. In this talk, I will present updates on the multi-frequency VLA radio surveys in the GOODS-N, Frontier, and CEERS fields that reach sub-uJy sensitivity and sub-arcsecond resolution at 3-10GHz. After summarizing the available data products and initial science results, the talk will focus on the imaging challenges faced to produce and characterize the aforementioned radio surveys. Finally, I will discuss how multi-frequency radio surveys of deep fields will serve as pathfinders for future ngVLA and SKA observational programs. The combination of the unprecedented SKA-ngVLA capabilities will allow us to probe the radio SED of distant galaxies on sub-kpc-scales across three decades of radio frequency, which will be paramount to establish radio continuum emission as a robust indicator of the level and spatial distribution of dust-obscured massive star formation in the early Universe.
