In a new study published in The Astrophysical Journal, astronomers have detailed how groups of stars can regulate their formation. Stars form in groups – or clusters – out of dense clouds of gas and ...

Galaxy formation unfolds through a complex interplay between gravitational dynamics, gas physics and energetic feedback from stars and black holes. Dark matter haloes collapse under gravity, drawing ...

Stellar feedback encompasses the processes by which newly formed stars return energy, momentum and newly synthesised elements to their surroundings. Radiation pressure from massive stars, powerful ...
