The methods by which various galaxies' constituent parts form are revealed by the alignment of galaxy spins with the universe's large-scale structure.

The distribution of galaxies reveals the universe's grand structure.

Enormous filamentary structures connecting massive clusters of galaxies make up this "cosmic web”.

Galaxies with a low-mass bulge and a predominant disc structure typically have their spin axes parallel to the nearest filament.

When galaxies merge, typically as they migrate down the filament, galaxy bulges expand.

According to Professor Scott Croom, an astronomer at the University of Sydney and a co-author on the article, "the direction of these mergers determines the spin flip.

This study clarifies how the two primary galaxies' components formed and how they relate to the vast structures and flows of matter throughout the cosmos.

Through this research, we can comprehend the crucial roles that mergers both the central bulge component and the spin flipping play in galaxies' development.
