When galaxies align: intrinsic alignments of the progenitors of elliptical galaxies in the Horizon-AGN simulation

James Bate, Nora Elisa Chisari, Sandrine Codis +5

Elliptical galaxies today appear aligned with the large-scale structure of the Universe, but it is still an open question when they acquire this alignment. Observational data is cu…

Galaxy morphological classification in deep-wide surveys via unsupervised machine learning

Garreth Martin, Sugata Kaviraj, Alex Hocking +2

Galaxy morphology is a fundamental quantity, that is essential not only for the full spectrum of galaxy-evolution studies, but also for a plethora of science in observational cosmo…

Massive spheroids can form in single minor mergers

R. A. Jackson, G. Martin, S. Kaviraj +4

Understanding how rotationally-supported discs transform into dispersion-dominated spheroids is central to our comprehension of galaxy evolution. Morphological transformation is la…

AGN in dwarf galaxies: frequency, triggering processes and the plausibility of AGN feedback

Sugata Kaviraj, Garreth Martin, Joseph Silk

While AGN are considered to be key drivers of the evolution of massive galaxies, their potentially significant role in the dwarf-galaxy regime (M*< 10^9 MSun) remains largely unexp…

Star formation in galaxies hosting AGN: A flat trend of star-formation rate with X-ray luminosity of galaxies hosting AGN in the SCUBA-2 Cosmology Legacy Survey

Joanna Ramasawmy, Jason Stevens, Garreth Martin +1

Feedback processes from active galactic nuclei (AGN) are thought to play a crucial role in regulating star formation in massive galaxies. Previous studies using \textit{Herschel} h…

The formation and evolution of low-surface-brightness galaxies

G. Martin, S. Kaviraj, C. Laigle +6

Our statistical understanding of galaxy evolution is fundamentally driven by objects that lie above the surface-brightness limits of current wide-area surveys (mu ~ 23 mag arcsec^-…
