Peculiar velocities of galaxies and clusters [PDF]
, 2000 We present a simple model for the shape of the distribution function of galaxy peculiar velocities. We show how both non-linear and linear theory terms combine to produce a distribution which has an approximately Gaussian core with exponential wings. The

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa
Advanced Science, EarlyView.Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

Quantitative Estimates of Environmental Effects on the Star Formation Rate of Disk Galaxies in Clusters of Galaxies [PDF]
, 1998 A simple model is constructed to evaluate the change of star formation rate of a disk galaxy due to environmental effects in clusters of galaxies. Three effects are investigated: (1) tidal force from the potential well of the cluster, (2) increase of ...

The Astrophysical Journal, 2020 Abstract The Next Generation Virgo Cluster Survey (NGVS) was designed to provide a deep census of baryonic structures in the Virgo cluster. The survey covers the 104 deg2 area from the core of Virgo out to one virial radius, in the u*griz bandpasses, to a point-source depth of g ∼ 25.9 mag (10σ) and a single pixel surface brightness ...

Proton Acceleration with Relativistic Electromagnetic Shock
Advanced Science, EarlyView.New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Behavior of f ( R ) gravity in the solar system, galaxies, and clusters [PDF]
, 2007 For cosmologically interesting f(R) gravity models, we derive the complete set of the linearized field equations in the Newtonian gauge, under environments of the solar system, galaxies, and clusters, respectively.

Advanced Science, EarlyView.A photovoltaic/photomultiplication dual‐mode organic photodetector is developed by integrating two different organic bulk‐heterojunctions, one introduces the photovoltaic effect, and the other triggers photomultiplication charge generation in the stacked device at different voltage polarities.

The Next Generation Virgo Cluster Survey (NGVS). XXXII. A Search for Globular Cluster Substructures in the Virgo Galaxy Cluster Core [PDF]
The Astrophysical Journal, 2018 Abstract Substructure in globular cluster (GC) populations around large galaxies is expected in galaxy formation scenarios that involve accretion or merger events, and it has been searched for using direct associations between GCs and structure in the diffuse galaxy light, or with GC kinematics.
