The major merger-active galactic nucleus connection up to the cosmic noon

A. La Marca, B. Margalef-Bentabol, L. Wang +3

Galaxy major mergers are a potential mechanism for triggering active galactic nuclei (AGN) activity, but their role remains debated, particularly beyond the local Universe. We aim…

Observationally derived change in the star formation rate as mergers progress

W. J. Pearson, L. Wang, V. Rodriguez-Gomez +2

Galaxy mergers can change the rate at which stars are formed. We can trace when these changes occur in simulations of galaxy mergers. However, for observed galaxies we do not know…

Euclid Quick Data Release (Q1). First Euclid statistical study of the active galactic nuclei contribution fraction

Euclid Collaboration, B. Margalef-Bentabol, L. Wang +331

Active galactic nuclei (AGN) play a key role in galaxy evolution but are challenging to identify due to their varied observational signatures. Furthermore, understanding their impa…

Euclid Quick Data Release (Q1). First Euclid statistical study of galaxy mergers and their connection to active galactic nuclei

Euclid Collaboration, A. La Marca, L. Wang +334

Galaxy major mergers are a key pathway to trigger AGN. We present the first detection of major mergers in the Euclid Deep Fields and analyse their connection with AGN. We construct…

Galaxy mergers classification using CNNs trained on Sérsic models, residuals and raw images

D. M. Chudy, W. J. Pearson, A. Pollo +5

Galaxy mergers are crucial for understanding galaxy evolution, and with large upcoming datasets, automated methods such as Convolutional Neural Networks (CNNs) are essential for ef…

Dust and Power: Unravelling the merger - active galactic nucleus connection in the second half of cosmic history

A. La Marca, B. Margalef-Bentabol, L. Wang +8

Galaxy mergers represent a fundamental physical process under hierarchical structure formation, but their role in triggering AGNs is still unclear. We aim to investigate the merger…

Determining the time before or after a galaxy merger event

W. J. Pearson, V. Rodriguez-Gomez, S. Kruk +1

Aims. This work aims to reproduce the time before or after a merger event of merging galaxies from the IllustrisTNG cosmological simulation using machine learning. Methods. Images…

Galaxy merger challenge: A comparison study between machine learning-based detection methods

B. Margalef-Bentabol, L. Wang, A. La Marca +14

Various galaxy merger detection methods have been applied to diverse datasets. However, it is difficult to understand how they compare. We aim to benchmark the relative performance…
