Euclid Quick Data Release (Q1): Euclid spectroscopy of quasars. 1. Identification and redshift determination of 3500 bright quasars
Euclid Collaboration, Y. Fu, R. Bouwens +354
The slitless spectroscopy mode of the NISP onboard Euclid has enabled efficient spectroscopy of objects within a large FoV. We present a large and homogeneous sample of bright quas…
Euclid Quick Data Release (Q1). Extending the quest for little red dots to z<4
Euclid Collaboration, L. Bisigello, G. Rodighiero +348
Recent James Webb Space Telescope (JWST) observations have revealed a population of sources with a compact morphology and a characteristic `v-shaped' continuum, namely blue at rest…
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…
Euclid Quick Data Release (Q1). Optical and near-infrared identification and classification of point-like X-ray selected sources
Euclid Collaboration, W. Roster, M. Salvato +316
To better understand the role of active galactic nuclei (AGN) in galaxy evolution, it is crucial to achieve a complete and pure AGN census. X-ray surveys are key to this, but ident…
Euclid Quick Data Release (Q1). Exploring galaxy morphology across cosmic time through Sersic fits
Euclid Collaboration, L. Quilley, I. Damjanov +333
We present the results of the single-component Sérsic profile fitting for the magnitude-limited sample of \IE galaxies within the 63.1 deg area of the Euclid Quick Data R…
Euclid Quick Data Release (Q1). A first view of the star-forming main sequence in the Euclid Deep Fields
Euclid Collaboration, A. Enia, L. Pozzetti +348
The star-forming main sequence (SFMS) is a tight relation observed between stellar masses and star formation rates (SFR) in a population of galaxies. This relation is observed at d…
