A Random Walk Model for Spatial Galaxy Distribution
Mathematics, 2021 A new statistical model of spatial distribution of observed galaxies is described. Statistical correlations are involved by means of Markov chain ensembles, whose parameters are extracted from the observable power spectrum by adopting of the Uchaikin ...

Joint galaxy–galaxy lensing and clustering constraints on galaxy formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We compare predictions for galaxy–galaxy lensing profiles and clustering from the Henriques et al. public version of the Munich semi-analytical model (SAM) of galaxy formation and the IllustrisTNG suite, primarily TNG300, with observations from KiDS + GAMA and SDSS-DR7 using four different selection functions for the lenses ...

GSA Central—A web platform to perform, learn, and discuss gene set analysis
Frontiers in Medicine, 2022 Gene Set Analysis (GSA) is one of the most commonly used strategies to analyze omics data. Hundreds of GSA-related papers have been published, giving birth to a GSA field in Bioinformatics studies.

Quenched Galaxies in Clusters of Galaxies and Their Outskirts [PDF]
Astrophysical Bulletin, 2020 Based on the SDSS data, the properties of galaxies with quenched star formation (QGs) within the "splashback"-radius of galaxy clusters $R_{\rm sp}$ and beyond it have been studied.

A Relationship between Nuclear Black Hole Mass and Galaxy Velocity Dispersion [PDF]
, 2000 We describe a correlation between the mass Mbh of a galaxy's central black hole and the luminosity-weighted line-of-sight velocity dispersion σe within the half-light radius.

Accretion of galaxy groups into galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼ 1014 $\rm M_\odot$ from the cosmological hydrodynamical simulation Illustris and follow their galaxies with stellar mass M⋆ ≥ 1.5 × 108 $\rm M_\odot$.

Gaia DR2 Distances to Planetary Nebulae
Galaxies, 2020 The aim of this work is to examine distances to planetary nebulae (PNe) together with other properties that were derived from them, using the astrometry of Gaia Data Release 2 (DR2).
