The formation and evolution of massive galaxies [PDF]

Research in Astronomy and Astrophysics, 2021
The discovery of massive galaxies at high redshifts, especially the passive ones, poses a big challenge for the current standard galaxy formation models. Here we use the semi-analytic galaxy formation model developed by Henriques et al.

Galaxy Formation and Evolution: Low Surface Brightness Galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
We investigatein detail the hypothesisthat low surfacebrightnessgalaxies(LSB) differfrom 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 ...

Understanding Galaxy Formation and Evolution [PDF]

, 2006
The old dream of integrating into one the study of micro and macrocosmos is now a reality. Cosmology, astrophysics, and particle physics intersect in a scenario (but still not a theory) of cosmic structure formation and evolution called Lambda Cold Dark ...

The formation and evolution of field massive galaxies [PDF]

Astrophysics and Space Science, 2003
The problem of the formation and evolution of field massive galaxies is briefly reviewed from an observational perspective. The motivations and the characteristics of the K20 survey are outlined. The redshift distribution of Ks<20 galaxies, the evolution of the rest-frame Ks-band luminosity function and luminosity density to z=1.5, the nature and ...

Formation and Evolution of Disk Galaxies [PDF]

Symposium - International Astronomical Union, 1999
We have developed a semianalitical approach to study galaxy formation and evolution in the cosmological context. Disk galaxies (dark matter halo+luminous disk) are considered to be formed through an extended process of gravitational collapse, whose character is determined by the statistical properties of the density fluctuation field assumed here to be

COSMOS2020: The galaxy stellar mass function. The assembly and star formation cessation of galaxies at 0.2 < z < 7.5 [PDF]

Astronomy & Astrophysics, 2022
How galaxies form, assemble, and cease their star-formation is a central question within the modern landscape of galaxy evolution studies. These processes are indelibly imprinted on the galaxy stellar mass function (SMF).

LIMFAST. II. Line Intensity Mapping as a Probe of High-redshift Galaxy Formation

The Astrophysical Journal, 2023
The epoch of reionization (EoR) offers a unique window into the dawn of galaxy formation, through which high-redshift galaxies can be studied by observations of both themselves and their impact on the intergalactic medium.
