Simulating supernova feedback in galaxy disks [PDF]
, 2012 In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

Chemical Composition of red horizontal branch stars in the thick disk of the Galaxy
, 2001 High-resolution spectra of 13 core helium-burning stars in the thick disk of the Galaxy have been obtained with the SOFIN spectrograph on the Nordic Optical Telescope to investigate abundances of up to 22 chemical elements.

Chemical abundances of LINER galaxies – nitrogen abundance estimations
Monthly Notices of the Royal Astronomical SocietyABSTRACT In this work, we investigated the nitrogen and oxygen abundances in a sample of galaxies with Low Ionization Nuclear Emission Regions (LINERs) in their nucleus. Optical spectroscopic data (3600 – 10 000 Å) of 40 LINERs from the Mapping Nearby Galaxies (MaNGAs) survey were considered.

The elemental abundance pattern in a galaxy at z = 2.626 [PDF]
Nature, 2003 The discovery of metal-poor stars (where metal is any element more massive than helium) has enabled astronomers to probe the chemical enrichment history of the Milky Way. More recently, element abundances in gas inside high-redshift galaxies has been probed through the absorption lines imprinted on the spectra of background quasars, but these have ...

Chemical Abundances Of The Leo II Dwarf Galaxy [PDF]
, 2009 We use previously published moderate-resolution spectra in combination with stellar atmosphere models to derive the first measured chemical abundance ratios in the Leo II dwarf Spheroidal (dSph) galaxy. We find that for spectra with signal-to-noise ratio

Rapid Chemical Enrichment by Intermittent Star Formation in GN-z11
The Astrophysical Journal LettersWe interpret the peculiar supersolar nitrogen abundance recently reported by the James Webb Space Telescope observations for GN-z11 ( z = 10.6) using our state-of-the-art chemical evolution models.

CARBON AND NITROGEN ABUNDANCES IN EARLY-TYPE GALAXIES [PDF]
The Astrophysical Journal, 2009 For the first time, we undertake a systematic examination of the nitrogen abundances for a sample of 35 early-type galaxies spanning a range of masses and local environment. The nitrogen-sensitive molecular feature at 3360Åhas been employed in conjunction with a suite of atomic- and molecular-sensitive indices to provide unique and definitive ...

Interdisciplinary Medicine, EarlyView.Liquid biopsy uses non‐invasive sampling of blood or body fluids to isolate circulating analytes, including circulating tumor DNA, circulating tumor cells, extracellular vesicles, and RNA. These are analyzed using next‐generation sequencing, qPCR, and proteomics to inform cancer detection, monitoring, and characterization. Figure created with BioRender.
