Περίληψη :
Most galaxies in the early Universe were compact, intensely star-forming dwarf galaxies whose radiation helped reionise the Universe. One of the best local analogues of these high-redshift galaxies are low-mass, low-metallicity star-forming dwarf galaxies, in particular Green Peas and Blueberries. Recent X-ray and radio observations reveal a broad range of luminosities within these populations. While many sources appear underluminous, some exhibit characteristics that may be consistent with low-luminosity active galactic nuclei. Multiwavelength observations are essential for distinguishing between emission driven by star formation and by possible AGN activity, offering new clues for interpreting these signatures in both nearby and high-redshift systems.
