Tidally triggered galaxy formation. II - Galaxy number counts [PDF]
The Astrophysical Journal, 1993 A model is presented for the evolution of the galaxy luminosity function in which the distribution of the galaxy masses, star formation time scales, and star formation turn-on redshifts is derived from the initial power spectrum of density fluctuations. The mass function of galaxy halos is very steep at low masses.

Diffuse Light in Milky Way–like Haloes
The Astrophysical Journal LettersWe investigate the diffuse light (DL) content of dark matter haloes in the mass range $11.5\leqslant \mathrm{log}{M}_{\mathrm{halo}}\leqslant 13$ , a range that also includes the dark matter halo of the Milky Way, taking advantage of a state-of-the-art ...

DLAs AND GALAXY FORMATION [PDF]
Modern Physics Letters A, 2007 Damped Lyman-α systems (DLAs) are useful probes of star formation and galaxy formation at high-redshift (hereafter high-z). We study the physical properties of DLAs and their relationship to Lyman break galaxies (LBGs) using cosmological hydrodynamic simulations based on the concordance Λ cold dark matter model.

Galaxy formation and evolution: low-surface-brightness galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We investigate in detail the hypothesis that low surface brightness galaxies (LSB) differ from ordinary galaxies simply because they form in halos with large spin parameters. We compute star formation rates using the Schmidt law, assuming the same gas infall dependence on surface density as used in models of the Milky Way.

The Astrophysical Journal Supplement SeriesWe build upon FEGA25 , a previously introduced semianalytic model (SAM) for galaxy formation and evolution, by focusing on its enhanced treatment of supernova (SN) and active galactic nucleus (AGN) feedback mechanisms.

Star Formation Rates, Metallicities, and Stellar Masses on Kiloparsec Scales in TNG50
The Astrophysical JournalIntegral field units have extended our knowledge of galactic properties to kiloparsec (or, sometimes, even smaller) patches of galaxies. These scales are where the physics driving galaxy evolution (feedback, chemical enrichment, etc.) take place ...

Collision‐induced Galaxy Formation
The Astrophysical Journal, 1998 We present a semi-analytical model in which galaxy collisions and strong tidal interactions, both in the field and during the collapse phase of groups and clusters help determine galaxy morphology. From a semi-analytical analysis based on simulation results of tidal collisions (Aguilar & White 1985), we propose simple rules for energy exchanges ...
