Galaxy morphology in rich clusters: Implications for the formation and evolution of galaxies
, 1980 A study of the galaxy populations in 55 rich clusters is presented together with a discussion of the implications for the formation and/or evolution of different morphological types.

A mass-dependent density profile for dark matter haloes including the influence of galaxy formation [PDF]
, 2014 We introduce a mass dependent density profile to describe the distribution of dark matterwithin galaxies, which takes into account the stellar-to-halo mass dependence of the responseof dark matter to baryonic processes.

The transformation of Spirals into S0 galaxies in the cluster environment
Frontiers in Astronomy and Space Sciences, 2015 We discuss the observational evidences of the morphological transformation of Spirals into S0 galaxies in the cluster environment exploiting two big databases of galaxy clusters: WINGS (0 ...

Numerical Simulations of Galaxy Formation [PDF]
Astrophysics and Space Science, 1997 An overview over the current status of modeling galaxies by means of numerical simulations is given. After a short description of how galaxies form in hierarchically clustering scenarios, success and failures of current simulations are demonstrated using three different applications: the morphology of present day galaxies; the appearance of high ...

Essential physics of early galaxy formation [PDF]
, 2014 We present a theoretical model embedding the essential physics of early galaxy formation (z ≃ 5-12) based on the single premise that any galaxy can form stars with a maximal limiting efficiency that provides enough energy to expel all the remaining gas ...

Exploring Galaxy Formation Models and Cosmologies with Galaxy Clustering
, 2012 Using N-body simulations and galaxy formation models, we study the galaxy stellar mass correlation and the two-point auto-correlation. The simulations are run with cosmological parameters from the WMAP first, third and seven year results, which mainly ...

Galaxy Formation: Bayesian History Matching for the Observable Universe [PDF]
, 2014 Cosmologists at the Institute of Computational Cosmology, Durham University, have developed a state of the art model of galaxy formation known as Galform, intended to contribute to our understanding of the formation, growth and subsequent evolution of ...

Back to the Green Valley: How to Rejuvenate an S0 Galaxy through Minor Mergers
Galaxies, 2015 About half of the S0 galaxies in the nearby Universe show signatures of recent or ongoing star formation. Whether these S0 galaxies were rejuvenated by the accretion of fresh gas is still controversial.

The evolution of the star-forming sequence in hierarchical galaxy formation models. [PDF]
, 2014 It has been argued that the specific star formation rates of star forming galaxies inferred from observational data decline more rapidly below z = 2 than is predicted by hierarchical galaxy formation models. We present a detailed analysis of this problem

The First Quenched Galaxies: When and How?
The Astrophysical Journal LettersMany quiescent galaxies discovered in the early Universe by JWST raise fundamental questions on when and how these galaxies became and stayed quenched. Making use of the latest version of the semianalytic model GAEA that provides good agreement with the ...
