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…

Galactic bars and active galactic nucleus fuelling in the second half of cosmic history

A. La Marca, M. T. Nardone, L. Wang +3

We investigate the role of galactic bars in fuelling and triggering Active Galactic Nucleus (AGN) in disc galaxies up to . We utilise a Deep Learning model, fine-tuned o…

Euclid Quick Data Release (Q1). The active galaxies of Euclid

Euclid Collaboration, T. Matamoro Zatarain, S. Fotopoulou +355

We present a catalogue of candidate active galactic nuclei (AGN) in the Quick Release (Q1) fields. For each source we collect multi-wavelength photometry and spec…

Euclid Quick Data Release (Q1). Active galactic nuclei identification using diffusion-based inpainting of Euclid VIS images

Euclid Collaboration, G. Stevens, S. Fotopoulou +271

Light emission from galaxies exhibit diverse brightness profiles, influenced by factors such as galaxy type, structural features and interactions with other galaxies. Elliptical ga…

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…
