چکیده
ABSTRACT The connection between halo gas acquisition through the circumgalactic medium and galaxy star formation (SF) has long been studied. In this series of two papers, we put interplay within context environment on large scales (several hundreds kpc), which, to a certain degree, maps out various paths for interactions. We use IllustrisTNG-100 simulation demonstrate that large-scale modulates angular momentum, resulting in either enhanced (Paper I) or suppressed II) SF inside galaxy. paper I), show around star-forming is often responsible triggering new episodes SF. Such an episodic pattern well synced with pulsating motion gas, one hand, receives momentum modulations from environment, yielding in-spiralling fuel reservoir, while, other affected by feedback activities centre. As result, present-day may have gone several cycles quiescent phases during its evolutionary history, carrying synchronized cadence ‘breathing out’ motions ?100 kpc.

Star-forming Complexes in Galaxies
Star complexes are the largest globular regions of star formation in galaxies. If there is a spiral density wave, nuclear ring, tidal arm, or other welldefined stellar structure, then gravitational instabilities in the gaseous component produce giant cloud complexes with a spacing of about three times the width. These gas complexes form star complexes, giving the familiar beads on a string of s...

The symbiosis of nuclear activity and star-formation in galaxies, as manifested in their spectral energy distributions (SEDs) is reviewed. Attention is drawn to an Hertzsprung-Russell diagram-equivalent for such objects, as well as to the importance of the SEDs in cosmological context.
