Formation and evolution of disk galaxies [PDF]

open access: yes, 2008
Global star formation is the key to understanding galaxy disk formation. This in turn depends on gravitational instability of disks and continuing gas accretion as well as minor merging. A key component is feedback from supernovae.

Formation of galaxies

open access: yesNuclear Physics B, 1985
Abstract The present theories of galaxy formation are reviewed. The relation between peculiar velocities and the correlation function of galaxies points to the possibility that galaxies do not form uniformly everywhere. Scale invariant properties of the cluster-cluster correlations are discussed. Comparing the correlation functions in a dimensionless

The role of submillimetre galaxies in hierarchical galaxy formation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2011
We study the role of submillimetre galaxies (SMGs) in the galaxy formation process in the Lambda Cold Dark Matter cosmology. We use the Baugh et al. (2005) semi-analytical model, which matches the observed SMG number counts and redshift distribution by assuming a top-heavy initial mass function (IMF) in bursts triggered by galaxy mergers.

Properties of Galaxy Groups in the SDSS: II.- AGN Feedback and Star Formation Truncation [PDF]

open access: yes, 2006
Successfully reproducing the galaxy luminosity function and the bimodality in the galaxy distribution requires a mechanism that can truncate star formation in massive haloes.

Genome‐wide identification and biological relevance of broccoli aquaporins

open access: yesThe Plant Genome, Volume 15, Issue 4, December 2022., 2022
Abstract Broccoli (Brassica oleracea var. italica) is an important crop worldwide, and its regular consumption is associated with health benefits due to the presence of various bioactive compounds. An optimal water balance and homeostasis are needed for plant growth; in this sense, aquaporins play a crucial role.

Dwarf galaxy formation induced by galaxy interactions [PDF]

open access: yes, 2000
Growing evidence has been accumulated for that some gas-rich dwarf galaxies are formed from material liberated by galaxy collisions and/or mergers. Also, gas-poor dwarf elliptical galaxies are often found in the central regions of clusters of galaxies.

On the Formation of Elliptical Galaxies [PDF]

open access: yesThe Astrophysical Journal, 1975
Simple collapse and violent relaxation models produce sharply cut off envelopes with ϱ(r) ∝ r–4, whereas actual elliptical galaxies have more extended envelopes approximately given by ϱ(r) ∝ r–3 as implied by Hubble's Law. Numerical models are presented, showing that when cosmological infall effects are included, galaxies are produced with more ...

The Science of Galaxy Formation [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
AbstractOur knowledge of the Universe remains discovery-led: in the absence of adequate physics-based theory, interpretation of new results requires a scientific methodology. Commonly, scientific progress in astrophysics is motivated by the empirical success of the “Copernican Principle”, that the simplest and most objective analysis of observation ...
