Description
Nearby galaxies offer an invaluable bridge between detailed, cloud-scale observations within the Milky Way and the integrated view of star formation in distant systems.
Thanks to ALMA, molecular gas structures, where star formation happens, can now be studied at sub-parsec scales in local galaxies.
Meanwhile, LOFAR (the Low‑Frequency Array) has improved our understanding at the other end of the spectrum, producing low‑frequency images that trace non‑thermal synchrotron emission from cosmic rays, crucial byproducts of massive star formation.
This talk presents recent progress from the LOFAR Nearby Galaxies Working Group, mainly focusing on the refinement of the low-frequency radio continuum–star formation rate relation, and on insights into how cosmic-ray transport and magnetic fields shape the observed radio emission.
Looking ahead to the Square Kilometre Array, its broader frequency coverage and enhanced sensitivity promise to complement LOFAR by capturing both non‑thermal and thermal components at unprecedented resolution.
The synergy will deepen our multi-band, multi-scale understanding of how galaxies form stars,transport cosmic rays, and build magnetic structures over cosmic time.
