Characterizing tidal features around galaxies in cosmological simulations (2024)
Journal Article

Tidal features provide signatures of recent mergers and offer a unique insight into the assembly history of galaxies. The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) will enable an unprecedentedly large survey of tidal features...

The morphological mix of dwarf galaxies in the nearby Universe (2024)
Journal Article

We use a complete, unbiased sample of 257 dwarf (10⁠) galaxies at z < 0.08, in the COSMOS field, to study the morphological mix of the dwarf population in low-density environments. Visual inspection of extremely deep optical images and their unsharp-... Read More about The morphological mix of dwarf galaxies in the nearby Universe.

A Physically Motivated Framework to Compare Pair Fractions of Isolated Low- and High-mass Galaxies across Cosmic Time (2024)
Journal Article

Low-mass galaxy pair fractions are understudied, and it is unclear whether low-mass pair fractions evolve in the same way as more massive systems over cosmic time. In the era of JWST, Roman, and Rubin, selecting galaxy pairs in a self-consistent way...

Ultraviolet and Blue Optical Imaging of UVCANDELS (2024)
Journal Article

The UltraViolet Imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey Fields (UVCANDELS) survey provided ultraviolet F275W imaging with coordinated parallel optical F435W imaging in four of the five CANDELS fields: GOODS-N, GO...

The formation of cores in galaxies across cosmic time - the existence of cores is not in tension with the ΛCDM paradigm (2024)
Journal Article

The 'core-cusp' problem is considered a key challenge to the ΛCDM paradigm. Haloes in dark matter only simulations exhibit 'cuspy' profiles, where density continuously increases towards the centre. However, the dark matter profiles of many observed g... Read More about The formation of cores in galaxies across cosmic time - the existence of cores is not in tension with the ΛCDM paradigm.
