The Cosmic Evolution of Faint Satellite Galaxies as a Test of Galaxy Formation and the Nature of Dark Matter

, 2013
The standard cosmological model based on cold dark matter (CDM) predicts a large number of subhalos for each galaxy-size halo. It is well known that matching the subhalos to the observed properties of luminous satellites of galaxies in the local universe

Clinically Inspired Multimodal Treatment Using Induced Neural Stem Cells‐Derived Exosomes Promotes Recovery of Traumatic Brain Injury through Microglial Modulation

Advanced Science, Volume 12, Issue 46, December 11, 2025.
This study explores the therapeutic potential of iNSC‐Exo via local and systemic delivery in TBI mice. It is found that iNSC‐Exo enhances NRXN signaling through Microglia_Nrg3 and Microglia_Rarb, effectively promoting functional and neurological recovery, suggesting a new therapeutic strategy for TBI. Abstract Traumatic brain injury (TBI) poses serious

Gas Accretion Can Drive Turbulence in Galaxies

The Astrophysical Journal, 2023
The driving of turbulence in galaxies is deeply connected with the physics of feedback, star formation, outflows, accretion, and radial transport in disks.

Simultaneous Observations of Quasi‐Orthogonal Nighttime MSTIDs at Conjugate African‐European Midlatitude Stations on 4 October 2018

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract Two quasi‐orthogonal nighttime medium‐scale traveling ionospheric disturbances (MSTIDs) were observed by conjugate midlatitude all‐sky imagers in Sutherland (32.4° ${}^{\circ}$S, 20.8° ${}^{\circ}$E; magnetic latitude: ∼ ${\sim} $−40.9° ${}^{\circ}$) and Asiago (45.87° ${}^{\circ}$N, 11.53° ${}^{\circ}$E; magnetic latitude: ∼40.3° ${\sim} 40.3{

An Empirical Consistent Redshift Bias: A Possible Direct Observation of Zwicky’s TL Theory

Particles
Recent advancements have shown tensions between observations and our current understanding of the Universe. Such observations may include the H0 tension and massive galaxies at high redshift that are older than traditional galaxy formation models have ...

Projection effects on pressure profiles: A case study of the Virgo replica [PDF]

EPJ Web of Conferences
An accurate mass calibration of galaxy clusters is a crucial step towards precise constraints on the cosmological parameters σ8 and Ωm from clusters. Cluster masses can be estimated assuming hydrostatic equilibrium, but several physical and observational

In silico, in vitro and ex vivo characterization of cystic fibrosis transmembrane conductance regulator pathogenic variants localized in the fourth intracellular loop and their rescue by modulators

British Journal of Pharmacology, Volume 182, Issue 24, Page 6063-6080, December 2025.
Background and Purpose Cystic fibrosis (CF) is due to loss‐of‐function variants of the CF transmembrane conductance regulator (CFTR) channel. The most effective treatment for people with CF carrying the F508del mutation is the triple combination of elexacaftor–tezacaftor–ivacaftor (ETI).

Ultra-fine dark matter structure in the Solar neighbourhood

, 2011
The direct detection of dark matter on Earth depends crucially on its density and its velocity distribution on a milliparsec scale. Conventional N-body simulations are unable to access this scale, making the development of other approaches necessary.

SF-R You Sure? The Conflicting Role of Star Formation Rates in Constraining the Evolution of Milky Way Analogs in Cosmological Simulations

The Astrophysical Journal
Milky Way analogs (MWAs) have long been studied by astronomers to place our Galaxy within an extragalactic context. With the power of cosmological simulations, we are now able to not only characterize MWAs today, but also watch as they evolve through ...
