TwO Parameters Semi Empirical Model (TOPSEM): Galaxy Evolution and Bulge/Disk Dicothomy from Two-stage Halo Accretion

The Astrophysical Journal, 2023
In recent years, increasing attention has been devoted to semi-empirical, data-driven models to tackle some aspects of the complex and still largely debated topic of galaxy formation and evolution. We here present a new semi-empirical model whose marking

The Suppression of Star Formation and the Effect of Galaxy Environment in Low-Redshift Galaxy Groups

, 2012
Understanding the interaction between galaxies and their surroundings is central to building a coherent picture of galaxy evolution. Here we use GALEX imaging of a statistically representative sample of 23 galaxy groups at z=0.06 to explore how local and

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Stellar Mass and Velocity Functions of Galaxies: Backward evolution and the fate of Milky Way siblings [PDF]

, 2010
We attempt in this paper to check the consistency of the observed Stellar Mass Function (SMF), SFR functions and the cosmic star formation rate density with simple backward evolutionary models. Starting from observed SMF for star-forming galaxies, we use

SDSS-IV MaNGA: faint quenched galaxies – I. Sample selection and evidence for environmental quenching [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
Using kinematic maps from the Sloan Digital Sky Survey (SDSS) Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we reveal that the majority of low-mass quenched galaxies exhibit coherent rotation in their stellar kinematics. Our sample includes all 39 quenched low-mass galaxies observed in the first year of MaNGA.

Evaluation of Zinc Borate and Melamine Polyphosphate Synergy on the Rheological, Thermal, Mechanical, Dimensional, and Flame Retardant Performance of rLLDPE/CaCO3 Composites for Pipes Applications

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
A synergistic flame retardant containing melamine polyphosphate and zinc borate was prepared and applied to provide rLLDPE/CaCO3 composites with superior flame retardancy. ABSTRACT The use of recycled thermoplastics is crucial for addressing environmental challenges such as waste management and sustainability.

Galaxy Quenching at the High Redshift Frontier: A Fundamental Test of Cosmological Models in the Early Universe with JWST-CEERS

The Astrophysical Journal
We present an analysis of the quenching of star formation in massive galaxies ( M _* > 10 ^9.5 M _⊙ ) within the first 0.5–3 Gyr of the Universe’s history utilizing JWST-CEERS data.

Cluster induced quenching of galaxies in the massive cluster XMMXCSJ2215.9-1738 at z~1.5 traced by enhanced metallicities inside half R200

, 2019
(Abridged) We explore the massive cluster XMMXCSJ2215.9-1738 at z~1.5 with KMOS spectroscopy of Halpha and [NII] covering a region that corresponds to about one virial radius.

The Argo Simulation: I. Quenching of Massive Galaxies at High Redshift as a Result of Cosmological Starvation [PDF]

, 2014
Observations show a prevalence of high redshift galaxies with large stellar masses and predominantly passive stellar populations. A variety of processes have been suggested that could reduce the star formation in such galaxies to observed levels ...
