Sentences with phrase «galaxy growth»
"Galaxy growth" refers to the process of how galaxies, which are large systems of stars, gas, and dust, increase in size and develop over time. Full definition
Observing distant objects allows us to peer back in time to early stages of the universe, across the most active period of galaxy growth when most stars were born.

«With ALMA we can see that there's a direct link between these radio bubbles inflated by the supermassive black hole and the future fuel for galaxy growth,» said Helen Russell, an astronomer with the University of Cambridge, UK, and lead author on a paper appearing in the Astrophysical Journal.
in distant starburst galaxies [4] These galaxies are known for a much higher rate of star formation compared to sedate Milky Way - like galaxies, making these structures ideal to study galaxy growth and the interplay between gas, dust, stars, and the black holes at the centers of galaxies..
«This study shows that it is possible a dense environment near the heart of the galaxy hinders and stops galaxy growth,» says Callingham, who did much of the research as a PhD student with the Australian Centre for All - shy Astrophysics (CAASTRO).
The researchers conclude that «reionization is an extended process associated with gradual galaxy growth,» Ellis said.
Researchers are keen to understand the feeding habits of black holes because such binges, called accretion events, have an enormous effect on their surroundings, shutting off galaxy growth by heating and expelling the gas needed to form new stars.
Because gas is the raw material for creating stars, NGC 253 is literally jettisoning its chances to be as big as it could be; but it's also giving astronomers a ringside seat on a phenomenon that probably puts a lid on galaxy growth throughout the universe.

«We now know that at least some very early galaxies have halos that are much more extended that previously considered, which may represent the future material for galaxy growth.»
These galaxies are known for a much higher rate of star formation compared to sedate Milky Way - like galaxies, making these structures ideal to study galaxy growth and the interplay between gas, dust, stars, and the black holes at the centers of galaxies.
They are among the oldest known stellar systems in the Universe and date back to near the beginning of galaxy growth and evolution.
