The relationship between Gas and Galaxies [PDF]

open access: yes, 2009
We have investigated the 2D 2-point correlation function, ƐAG, between low column density Lya absorbers and galaxies at a redshift z ~ 1 for the first time.

Testing Galaxy Formation Models with the Stellar Mass–Halo Mass Relations for Star-forming and Quiescent Galaxies

open access: yesThe Astrophysical Journal
The tight relationship between the stellar mass and halo mass of galaxies is one of the most fundamental scaling relations in galaxy formation and evolution. It has become a critical constraint for galaxy formation models.

The Formation of Stellar Halos in Late-Type Galaxies

open access: yes, 2015
Near-field observations may provide tight constraints - i.e. "boundary conditions" - on any model of structure formation in the Universe. Detailed observational data have long been available for the Milky Way (e.g. Freeman $\&$ Bland-Hawthorn 2002) and have provided tight constraints on several Galaxy formation models (e.g. Abadi et al. 2003, Bekki

A Context‐Aware Decision Support Framework for Scientific Experiment Configuration

open access: yesSoftware: Practice and Experience, Volume 56, Issue 9, Page 1100-1119, September 2026.
ABSTRACT Introduction Defining an experimental configuration is a complex decision problem for early‐stage researchers, who must map goals, constraints, and requirements onto datasets, algorithms, and parameter settings that directly affect experimental outcomes.

Constraining dark energy using real and mock galaxy surveys [PDF]

open access: yes, 2009
In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

Stellar Populations in the Extreme Outer Halo of the Spiral Galaxy M96

open access: yesThe Astrophysical Journal
We use deep Hubble Space Telescope imaging to study stellar populations in the outer halo of the spiral galaxy M96, located in the dynamically active Leo I galaxy group.

Stellar streams around dwarf galaxies in the local Universe

open access: yesAstronomy & Astrophysics
Context. While mergers between massive galaxies and their dwarf satellites have been well studied, the properties of dwarf–dwarf satellite mergers are not well constrained.

Association mapping for canopy temperature under irrigated and rainfed conditions at 12 environments identified both known and novel genetic loci

open access: yesThe Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Soybean (Glycine max (L.) Merrill) is the most widely cultivated oilseed crop and faces significant yield challenges due to drought stress. Canopy temperature has been proposed as an effective proxy for evaluation of differences in genotypic responses to water limitation, as well as indirectly assessing transpiration and stomatal conductance ...

The clustering of dark matter, haloes & galaxies [PDF]

open access: yes, 2008
In this thesis I study the spatial distribution of galaxies, haloes and dark matter particles using a suite of state-of-art cosmological N-body simulations of the growth structure in the Universe.

LATIS: Constraints on the Galaxy–Halo Connection at z ∼ 2.5 from Galaxy–Galaxy and Galaxy–Lyα Clustering

open access: yesThe Astrophysical Journal
The connection between galaxies and dark matter halos is often quantified using the stellar mass–halo mass (SMHM) relation. Optical and near-infrared imaging surveys have led to a broadly consistent picture of the evolving SMHM relation based on ...
