Marta Reina-Campos

PhD student and IMPRS Fellow


I am a fourth-year PhD student at the Universität Heidelberg working with Dr. Diederik Kruijssen in the MUSTANG group. My work focuses on the formation and evolution of stellar clusters in a cosmological context, using analytical models and numerical simulations, with the goal of understanding how galaxy evolution shapes the observed cluster populations and how we can use them to infer the assembly histories of their host galaxies.

Research interests


I am interested in understanding how stellar clusters form and evolve in a hierarchical galaxy assembly context, with the ultimate goal of using old, massive stellar cluster populations as near-field cosmological tracers. During my PhD I have worked with state-of-the-art cosmological hydrodynamical simulations that include the formation and evolution of the stellar cluster populations alongside the formation and assembly of their host galaxies: the E-MOSAICS simulations, see Pfeffer et al. (2018) and Kruijssen et al. (2019), and the EMP-MOSAICS simulations, Reina-Campos et al. (2019, in prep.). The following images describe some of the main results that I have found:

Predictions for the maximum mass of stellar clusters depending on their natal environment. We find that stellar feedback reduces the maximum mass scale in environments with low shear and low gas surface densities, i.e. the outskirts of Local Universe spiral galaxies (<a href='https://ui.adsabs.harvard.edu/abs/2017MNRAS.469.1282R/abstract' class = 'mrc-hl-white'>Reina-Campos & Kruijssen 2017</a>). Initial-to-final mass ratio of all surviving clusters in the E-MOSAICS simulations as a function of environment (<a href='https://ui.adsabs.harvard.edu/abs/2018MNRAS.481.2851R/abstract' class = 'mrc-hl-white'>Reina-Campos et al. 2018</a>). Projected gas surface density of two merging galaxies at z~3 with their massive (M>1e5 MSun) stellar cluster populations evolved colour-coded by their ages. These galaxies are evolved with the EMP-MOSAICS model and their growth leads to a Milky-Way mass (~1e12 MSun) galaxy at z=0 (Reina-Campos et al. 2019 in prep.).
Predictions of the maximum molecular cloud and stellar cluster mass scales in the Milky Way as a function of galactocentric radius. We find that the interplay between stellar feedback and centrifugal forces sets the constant maximum cloud and cluster mass scales observed in the Milky Way (<a href='https://ui.adsabs.harvard.edu/abs/2017MNRAS.469.1282R/abstract' class = 'mrc-hl-white'>Reina-Campos & Kruijssen 2017</a>). Median formation histories of stars, clusters and globular clusters (M>1e5 MSun) among the E-MOSAICS simulations for different metallcity bins (<a href='https://ui.adsabs.harvard.edu/abs/2019MNRAS.486.5838R/abstract' class = 'mrc-hl-white'>Reina-Campos et al. 2019</a>). Total initial-to-present mass ratios of clusters and GCs (first row), mass fraction of halo stars contributed by clusters and GCs (second row), mass fraction of chemically-distinct halo stars contributed from clusters and GCs (third row), and mass fraction of chemically-distinct halo stars contributed by clusters and GCs matching the metallicity range of <a href='https://ui.adsabs.harvard.edu/abs/2019A%26A...625A..75K/abstract' class = 'mrc-hl-white'>Koch et al. (2019)</a> (fourth row) in each of our 25 present-day Milky Way-mass simulations. We find that the disruption of globular clusters, defined as massive (M>1e5 MSun) stellar clusters, plays a sub-dominant role in the buil-up of the stellar halo (Reina-Campos et al. subm.).
