Disc-dominated galaxies can be difficult to accommodate in a hierarchical formation scenario such as Λ cold dark matter (ΛCDM), where mergers are an important growth mechanism. However, observational evidence indicates that these common the Universe. We seek characterise conditions lead of disc-dominated within ΛCDM. used dynamical decomposition stellar particles all with mass M_*= M_⊙ cosmological hydrodynamical simulation Illustris TNG100. selected sample 43 mostly-disc have less than ∼...
Galaxy formation is intrinsically connected to the distinct evolutionary processes of disk and spheroidal systems, which are fundamental stellar components galaxies. Understanding mutual dynamical interplay co-evolution these requires a detailed analysis allow for disentanglement between them. We introduce JEHistogram, new method decomposition simulated galaxies into components, utilizing angular momentum energy star particles. evaluate its performance against five previously established...
Disc dominated galaxies can be difficult to accommodate in a hierarchical formation scenario like $\Lambda$CDM, where mergers are an important growth mechanism. However, observational evidence indicates that these common. We seek characterise the conditions lead of disc within $\Lambda$CDM. use dynamical decomposition all with stellar mass $M_*=[10^{10} \rm - 10^{11}]\; M_\odot$ simulation Illustris TNG100. select sample 43 mostly-disc having less than $\sim 10\%$ their into bulge component....
