Bulgeless galaxies with growing black holes
Mergers make bulges in galaxies and black holes generally live in bulges, so mergers must grow black holes – simple. That was until we found bulgeless galaxies containing growing black holes…
Two roads through the green valley
Large surveys of galaxies have revealed a bimodal color distribution: most galaxies tend to be red or blue, leaving a gap in the middle known as the green valley. The authors of this paper use morphologies provided by the Galaxy Zoo project to show that not all galaxies take the same quick path through the green valley.
Compact Galaxies in the Nearby Universe
Small and massive compact galaxies are some of the hardest galaxies to find, but they could potentially reveal how galaxies evolved in the early universe.
Young Stars in the Galactic Bulge- An Outcome of Internal Evolution
The recent discovery of young stars in the Milky Way’s galactic bulge have raised new questions about galaxy formation. In this paper, a new simulation shows that such stars could be an outcome of natural evolution in the disc over time.
The Changing Faces of Active Galactic Nuclei
Has a multi-wavelength study of AGN across a large redshift range revealed that these energetic giants do not impact upon their host galaxy as significantly as previously thought?
Finding Relics of Galaxy Formation
Could the strange-looking irregular galaxies actually be remnants of the birth of galaxies? This paper demonstrates a method to find such galaxies.
