Dynamical and chemical evolution of NGC1569

, 2005
Blue Compact Dwarf and Dwarf Irregular galaxies are generally believed to be unevolved objects, due to their blue colors, compact appearance and large gas fractions.

Turbulent Gas-rich Disks at High Redshift: Origin of Thick Stellar Disks Through 3D “Baryon Sloshing”

The Astrophysical Journal
In response to recent observations from JWST and Atacama Large Millimeter Array, we explore a new class of dynamically self-consistent models that mimics a plausible progenitor of the Milky Way over a wide range of disk gas fractions, f _gas .

Chemical evolution of local galaxies

, 2022
We show the results of a study using the spectral synthesis technique study to measure the chemical evolution of local galaxies. The main parameters measured are the chemical enrichment history (ChEH) and the evolution of the stellar mass-metallicity relation (MZR) over cosmic time.

High‐Contrast Colorless‐to‐Colored Thermochromic Materials

Small, EarlyView.
We developed new three‐component thermochromic systems showing reversible colorless‐to‐colored transition. Our general empirical rule applies to diverse fatty acid phase change materials and leuco dyes, enabling easily tunable transition temperature and activated colors (blue, cyan, green, pink, grey). Solid particles of these materials were integrated

Chemical Evolution Of Galaxies And Intracluster Medium [PDF]

, 2004
In this series of lectures I discuss the basic principles and the modelling of the chemical evolution of galaxies. In particular, I present models for the chemical evolution of the Milky Way galaxy and compare them with the available observational data.

Adsorption of Helium on Cationic or Anionic Tetracene and Pentacene

Small Structures, EarlyView.
How does the arrangement of helium atoms that are adsorbed on tetracene or pentacene ions change with increasing coverage? When does the adsorption layer change from 1D to 2D, and to 3D? Is the transition abrupt? Are the helium atoms localized? Is the arrangement the same for cations and anions? What changes as the acene grows in length?

A JWST/MIRI View of the Interstellar Medium in M83. I. Resolved Molecular Hydrogen Properties, Star Formation, and Feedback

The Astrophysical Journal
We present a spatially resolved (∼3 pc pixel ^−1 ) analysis of the distribution, kinematics, and excitation of warm H _2 gas in the nuclear starburst region of M83.

The building up of the disk galaxy M33 and the evolution of the metallicity gradient

, 2007
The evolution of radial gradients of metallicity in disk galaxies and its relation with the disk formation are not well understood. Theoretical models of galactic chemical evolution make contrasting predictions about the time evolution of metallicity ...

Radiation‐Induced Degradation in Polymeric Materials: Alterations in Physical–Chemical Properties and Their Effects on Electrical Performance of Insulation Systems

High Voltage, EarlyView.
ABSTRACT This paper investigates the effects of radiation on polymeric materials used as insulation systems in electrical equipment such as cables for nuclear and particle accelerator applications. After a detailed description of the physics of radiation‐induced damage in the polymeric matrix, a comprehensive analysis of the physical–chemical and ...

A chemical evolution model for galaxy clusters [PDF]

, 2001
We develop a toy-model for the chemical evolution of the intracluster medium, polluted by the galactic winds from elliptical galaxies. The model follows the "galaxy formation history" of cluster galaxies, constrained by the observed luminosity function ...
