Journal Article
Kawata, D., Gibson, B. K., Barnes, D. J., Grand, R. J., & Rahimi, A. (2014). Numerical simulations of bubble-induced star formation in dwarf irregular galaxies with a novel stellar feedback scheme. Monthly notices of the Royal Astronomical Society, 438(2), 1208-1222. https://doi.org/10.1093/mnras/stt2267

To study the star formation and feedback mechanism, we simulate the evolution of an isolated dwarf irregular galaxy (dIrr) in a fixed dark matter halo, similar in size to Wolf–Lundmark–Melotte, using a new stellar feedback scheme. We use the new vers... Read More about Numerical simulations of bubble-induced star formation in dwarf irregular galaxies with a novel stellar feedback scheme.

Journal Article
Alpaslan, M., Robotham, A. S. G., Driver, S., Norberg, P., Baldry, I., Bauer, A. E., Bland-Hawthorn, J., Brown, M., Cluver, M., Colless, M., Foster, C., Hopkins, A., Van kampen, E., Kelvin, L., Lara-Lopez, M. A., Liske, J., Lopez-Sanchez, A.

Monthly notices of the Royal Astronomical Society, 438(1), 177-194. https://doi.org/10.1093/mnras/stt2136

From a volume-limited sample of 45 542 galaxies and 6000 groups with z ≤ 0.213, we use an adapted minimal spanning tree algorithm to identify and classify large-scale structures within the Galaxy And Mass Assembly (GAMA) survey. Using galaxy groups,... Read More about Galaxy and mass assembly (GAMA): The large-scale structure of galaxies and comparison to mock universes.

Phase mixing due to the Galactic potential: steps in the position and velocity distributions of popped star clusters (2013)
Journal Article
Candlish, G. N., Smith, R., Fellhauer, M., Gibson, B. K., Kroupa, P., & Assmann, P. (2014). Phase mixing due to the Galactic potential: steps in the position and velocity distributions of popped star clusters. Monthly notices of the Royal Astronomical Society, 437(4), 3702-3717. https://doi.org/10.1093/mnras/stt2166

As star clusters are expected to form with low star formation efficiencies, the gas in the cluster is expelled quickly and early in their development: the star cluster ‘pops’. This leads to an unbound stellar system, evolving in the Galactic potentia...

The effect of cosmic magnetic fields on the metagalactic ionization background inferred from the Lyman α forest (2013)
Journal Article
Chongchitnan, S., & Meiksin, A. (2014). The effect of cosmic magnetic fields on the metagalactic ionization background inferred from the Lyman α forest. Monthly notices of the Royal Astronomical Society, 437(4), 3639-3646. https://doi.org/10.1093/mnras/stt2169

The sources which reionized the intergalactic medium by redshift ̃6 are still unknown. A severe constraint on the ionization process is the low emissivity required to maintain the ionization in the Lya forest. Simulation-calibrated observations sugge...

Environments and morphologies of red sequence galaxies with residual star formation in massive clusters (2013)
Journal Article
Crossett, J. P., Pimbblet, K. A., Stott, J. P., & Jones, D. H. (2014). Environments and morphologies of red sequence galaxies with residual star formation in massive clusters. Monthly notices of the Royal Astronomical Society, 437(3), 2521-2530. https://doi.org/10.1093/mnras/stt2065

We present a photometric investigation into recent star formation in galaxy clusters at z ∼ 0.1. We use spectral energy distribution templates to quantify recent star formation in large Xray-selected clusters from the LARCS survey using matched GALEX...

The [α/Fe] ratios of very metal-poor stars within the integrated galactic initial mass function theory (2013)
Journal Article

The aim of this paper is to quantify the amplitude of the predicted plateau in [α/Fe] ratios associated with the most metal-poor stars of a galaxy. We assume that the initial mass function (IMF) in galaxies is steeper if the star formation rate (SFR)...

The Astrophysical journal, 778(2), 86. https://doi.org/10.1088/0004-637x/778/2/86

Diffuse interstellar bands (DIBs) are usually observed in spectra of hot stars, where interstellar lines are rarely blended with stellar ones. The need for hot stars is a strong limitation in the number of sightlines we can observe and their distribu...
