The three hundred project: thermodynamical properties, shocks, and gas dynamics in simulated galaxy cluster filaments and their surroundings (2023)
Journal Article

Using cosmological simulations of galaxy cluster regions from THE THREE HUNDRED project, we study the nature of gas in filaments feeding massive clusters. By stacking the diffuse material of filaments throughout the cluster sample, we measure average...

The probability of identifying the cosmic web environment of galaxies around clusters motivated by the Weave Wide Field Cluster Survey (2023)
Journal Article

Upcoming wide-field spectroscopic surveys will observe galaxies in a range of cosmic web environments in and around galaxy clusters. In this paper, we test and quantify how successfully we will be able to identify the environment of individual galaxi...

Euclid preparation: XXVI. The Euclid Morphology Challenge: Towards structural parameters for billions of galaxies (2023)
Journal Article

The various Euclid imaging surveys will become a reference for studies of galaxy morphology by delivering imaging over an unprecedented area of 15 000 square degrees with high spatial resolution. In order to understand the capabilities of measuring m... Read More about Euclid preparation: XXVI. The Euclid Morphology Challenge: Towards structural parameters for billions of galaxies.

Euclid preparation: XXV. The Euclid Morphology Challenge: Towards model-fitting photometry for billions of galaxies (2023)
Journal Article

The European Space Agency's Euclid mission will provide high-quality imaging for about 1.5 billion galaxies. A software pipeline to automatically process and analyse such a huge amount of data in real time is being developed by the Science Ground Seg... Read More about Euclid preparation: XXV. The Euclid Morphology Challenge: Towards model-fitting photometry for billions of galaxies.

The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation (2023)
Journal Article

WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, saw first light in late 2022. WEAVE comprises a new 2-deg field-of-view prime-focus corrector system, a nearly 1000-multiplex fibre pos...

The Three Hundred Project: Connection between star formation quenching and dynamical evolution in and around simulated galaxy clusters (2022)
Journal Article

In this work, we combine the semi-analytic model of galaxy formation and evolution SAG with the 102 relaxed simulated galaxy clusters from THE THREE HUNDRED project, and we study the link between the quenching of star formation (SF) and the physical... Read More about The Three Hundred Project: Connection between star formation quenching and dynamical evolution in and around simulated galaxy clusters.

Forecasting the success of the WEAVE Wide-Field Cluster Survey on the extraction of the cosmic web filaments around galaxy clusters (2022)
Journal Article

Next-generation wide-field spectroscopic surveys will observe the infall regions around large numbers of galaxy clusters with high sampling rates for the first time. Here we assess the feasibility of extracting the large-scale cosmic web around clust...

A Simulation-driven Deep Learning Approach for Separating Mergers and Star-forming Galaxies: The Formation Histories of Clumpy Galaxies in All of the CANDELS Fields (2022)
Journal Article

Being able to distinguish between galaxies that have recently undergone major-merger events, or are experiencing intense star formation, is crucial for making progress in our understanding of the formation and evolution of galaxies. As such, we have...

The Value of ArtScience: improving the balance in collaboration practices between artists and scientists can impact knowledge production (2022)
Journal Article

In a time in which scientific knowledge is in danger of being discredited, we return to the responsibility of art and science. There is widespread optimism that collaborations between artists and scientists can develop solutions to complex problems,...

Euclid preparation: XIII. Forecasts for galaxy morphology with the Euclid Survey using deep generative models (2022)
Journal Article

We present a machine learning framework to simulate realistic galaxies for the Euclid Survey, producing more complex and realistic galaxies than the analytical simulations currently used in Euclid. The proposed method combines a control on galaxy sha... Read More about Euclid preparation: XIII. Forecasts for galaxy morphology with the Euclid Survey using deep generative models.

An inventory of galaxies in cosmic filaments feeding galaxy clusters: galaxy groups, backsplash galaxies, and pristine galaxies (2021)
Journal Article

Galaxy clusters grow by accreting galaxies from the field and along filaments of the cosmic web. As galaxies are accreted they are affected by their local environment before they enter (pre-processing), and traverse the cluster potential. Observation...

Mapping and characterization of cosmic filaments in galaxy cluster outskirts: strategies and forecasts for observations from simulations (2020)
Journal Article

Upcoming wide-field surveys are well-suited to studying the growth of galaxy clusters by tracing galaxy and gas accretion along cosmic filaments. We use hydrodynamic simulations of volumes surrounding 324 clusters from The ThreeHundred project to dev...
