Galaxy and Mass Assembly (GAMA): Properties and evolution of red spiral galaxies (2019)
Journal Article
Brown, M. J., Mahajan, S., Gupta, K. K., Rana, R., Brown, M. J. I., Phillipps, S., …Wang, L. (2020). Galaxy and Mass Assembly (GAMA): Properties and evolution of red spiral galaxies. Monthly notices of the Royal Astronomical Society, 491(1), 398-408. https://doi.org/10.1093/mnras/stz2993

We use multi-wavelength data from the Galaxy and Mass Assembly (GAMA) survey to explore the cause of red optical colours in nearby (0.002 < z < 0.06) spiral galaxies. We show that the colours of red spiral galaxies are a direct consequence of some en... Read More about Galaxy and Mass Assembly (GAMA): Properties and evolution of red spiral galaxies.

Redshift measurement through star formation (2019)
Journal Article
Lindholmer, M. O., & Pimbblet, K. A. (2019). Redshift measurement through star formation. Astronomy and Astrophysics, 629, https://doi.org/10.1051/0004-6361/201833046

© ESO 2019. In this work we use the property that, on average, star formation rate increases with redshift for objects with the same mass - the so called galaxy main sequence - to measure the redshift of galaxy clusters. We use the fact that the gene... Read More about Redshift measurement through star formation.

Monthly notices of the Royal Astronomical Society, 489(2), 2830–2843. https://doi.org/10.1093/mnras/stz2237

The Galaxy And Mass Assembly (GAMA) survey has morphologically identified a class of ‘Little Blue Spheroid’ (LBS) galaxies whose relationship to other classes of galaxies we now examine in detail. Considering a sample of 868 LBSs, we find that such g... Read More about Star-Forming, Rotating Spheroidal Galaxies in the GAMA and SAMI Surveys.

The effect of minor and major mergers on the evolution of low excitation radio galaxies (2019)
Journal Article

We use deep, μ r lesssim 28 mag arcsec−2, r-band imaging from the Dark Energy Camera Legacy Survey to search for past, or ongoing, merger activity in a sample of 282 low-excitation radio galaxies (LERGs) at z < 0.07. Our principal aim is to assess t... Read More about The effect of minor and major mergers on the evolution of low excitation radio galaxies.
