An improved model of chemical evolution within the Milky Way galaxy

, 2016
This thesis project involves the improvement of existing computer code, which is used in modeling the galactic chemical evolution (GCE) of the Milky Way Galaxy. The ultimate goal of a GCE analysis is to reliably predict abundances for all observationally

Direct Abundance Maps and Radial Metallicity Gradients of Two Galaxies at z ∼ 4–5 in the GARDEN Survey

The Astrophysical Journal
We investigate galaxies in the Galaxies at All Redshifts Deciphered and Explained with the NIRSpec microshutter array (MSA; GARDEN) survey that exhibit auroral emission lines, enabling spatially resolved measurements of electron temperature and direct ...

Progress of metabolomics‐centric multi‐omics research in medicine

iMetaOmics, Volume 3, Issue 2, June 2026.
The graphical abstract illustrates a holistic roadmap for metabolomics‐centric multi‐omics integration in medical research. The upper panel depicts the technological transition from traditional bulk analysis to high‐resolution single‐cell and spatial methodologies, specifically addressing inherent challenges such as molecular complexity and dynamic ...

Chemical evolution of galactic systems

, 2005
This thesis explores the chemical signatures of galaxy formation and evolution using a software package designed specifically for this investigation. We describe the development of this multi-zone chemical evolution code, which simulates the spacetime ...

Mapping Immunity With Cutting‐Edge Spatial Biology and Tissue Cytometry Innovations

MedComm, Volume 7, Issue 6, June 2026.
This review explores how spatial biology integrates multiplexed imaging and tissue cytometry to reveal immune organization within native tissue contexts. ABSTRACT The immune system operates within organized tissue landscapes, where spatial relationships between cells shape the nature and outcome of immune responses.

Chemical Doppelgangers in GALAH DR3: The Distinguishing Power of Neutron-capture Elements among Milky Way Disk Stars

The Astrophysical Journal
The observed chemical diversity of Milky Way stars places important constraints on Galactic chemical evolution and the mixing processes that operate within the interstellar medium. Recent works have found that the chemical diversity of disk stars is low.

Predicting Nitrogen Isotope Fractionation in Nitrate Deposition on Early Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Noachian and early Hesperian Mars were likely warm and wet, with an atmosphere abundant in molecular nitrogen. The recent discovery of nitrate deposits in the Yellowknife Bay mudstones at Gale Crater confirm the existence of nitrogen oxides (NOX) on Noachian Mars. The processes responsible for the production of these nitrates would fractionate

Galaxy evolution by chemical and SED model

, 2012
2010/2011In this thesis, we have studied the ISM, QSO, LGRB hosts and LBGs by galactic chemical evolution and spectro-photometric models. We also tested the so-called mono- lithic scenario of elliptical galaxies formation.
