The Luminosity Function of cluster galaxies. III.

, 2003
We investigated the optical properties of 7 clusters of galaxies observed in three colors over the range of absolute magnitudes $ -24 \leq { M} \leq -12$.

ODIN: Probing the LAE Lyα Luminosity Function across Cosmic Time and Different Environments

The Astrophysical Journal
The ubiquity and relative ease of discovery make 2 ≲  z  ≲ 5 Ly α emitting galaxies (LAEs) ideal tracers for large-scale structure of the distant Universe.

Correlation function of the luminosity distances

, 2017
We present the correlation function of the luminosity distances in a flat ΛCDM universe. Decomposing the luminosity distance fluctuation into the velocity, the gravitational potential, and the lensing contributions in linear perturbation theory, we study

The white dwarf luminosity function – I. Statistical errors and alternatives [PDF]

, 2006
The white dwarf luminosity function is an important tool for the study of the solar neighbourhood, since it allows the determination of the age of the Galactic disc.

The Redshift Evolution of the Luminosity Function of Type II Gamma-Ray Bursts

The Astrophysical Journal
As of 2023 December, the Neil Gehrels Swift Observatory satellite has detected more than 1600 gamma-ray bursts (GRBs). We select 307 Type II GRBs for constructing the luminosity function (LF) based on the following criteria: (1) duration T _90 ≥ 2 s; (2)

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

Advanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Lenticular galaxy formation: possible luminosity dependence [PDF]

, 2007
We investigate the correlation between the bulge effective radius (re ) and disk scale length (rd ) in the near-infrared K band for lenticular galaxies in the field and in clusters.

The Global, Local and Cluster Galaxy Luminosity Function

, 2015
We review selected measurements of the galaxy luminosity function including the field, the local group, the local sphere, nearby clusters (Virgo, Coma and Fornax) and clusters in general.

Bright z ∼ 9 Galaxies in Parallel: The Bright End of the Rest-frame UV Luminosity Function from HST Parallel Programs

The Astrophysical Journal
The abundance of bright galaxies at z > 8 can provide key constraints on models of galaxy formation and evolution, as the predicted abundance varies greatly when different physical prescriptions for gas cooling and star formation are implemented.
