Irrespective of these limitations, the Firefly Sparkle provides insights into the early galaxy formation. With massive star clusters exhibiting high surface density, low metallicity, high electron temperature and hints of a top-heavy IMF, the Firefly Sparkle exhibits the hallmarks of star formation in...
The galaxy consists basically of two parts, S and N. In the spectrum of S are found broad and strong emission lines H-alpha, forbidden O III 5007 and 4959, H-beta, H-gamma, and H-delta, characteristic of Sy 1 galaxies. Two components are observed in the broad wings of the latter ...
