Journal Article
Lazar, I., Kaviraj, S., Watkins, A., Martin, G., Bichang’a, B., & Jackson, R. (2024). The morphological mix of dwarf galaxies in the nearby Universe. Monthly Notices of the Royal Astronomical Society, 529(1), 499-518. https://doi.org/10.1093/mnras/stae510

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
Chamberlain, K., Besla, G., Patel, E., Rodriguez-Gomez, V., Torrey, P., Martin, G., …Stierwalt, S. (2024). A Physically Motivated Framework to Compare Pair Fractions of Isolated Low- and High-mass Galaxies across Cosmic Time. Astrophysical Journal, 962(2), Article 162. https://doi.org/10.3847/1538-4357/ad19d0

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...

The formation of cores in galaxies across cosmic time - the existence of cores is not in tension with the ΛCDM paradigm (2024)
Journal Article
Jackson, R. A., Kaviraj, S., Yi, S. K., Peirani, S., Dubois, Y., Martin, G., …Kraljic, K. (2024). The formation of cores in galaxies across cosmic time - the existence of cores is not in tension with the ΛCDM paradigm. Monthly Notices of the Royal Astronomical Society, 528(2), 1655–1667. https://doi.org/10.1093/mnras/stae056

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.
