Euclid Quick Data Release (Q1): The impact of AGN emission on SED-derived physical properties

Euclid Collaboration, B. Laloux, A. Bongiorno +309

The Euclid Quick Data Release (Q1) is a powerful dataset to study active galactic nuclei (AGN) and their host galaxies. Deriving their physical properties through multi-component s…

Euclid: Early Release Observations -- Internal kinematics and the convective-transition gap of NGC 6397

M. Griggio, M. Libralato, R. Gerasimov +130

We present a 'multiple-pass' data-reduction tool designed for Euclid, based on software developed for the Hubble Space Telescope (HST), which improves the astrometric and photometr…

Euclid: Disky titans -- surprisingly high star formation efficiency in two brightest group galaxies at

F. Gentile, E. Daddi, D. Elbaz +165

We present the discovery of two disky titans in the first data release of the Euclid satellite. These sources are massive () star-forming (SFR /…

Euclid: Galaxy morphology and photometry from bulge-disc decomposition of Early Release Observations

L. Quilley, V. de Lapparent, M. Bolzonella +168

The background galaxies in Euclid ERO images of the Perseus cluster make up a remarkable sample in its combination of 0.57 deg area, 25.3 and 23.2 AB mag depth, as well as 0.1"…

Euclid preparation. Far-infrared predictions for Euclid galaxy catalogues: cluster, protocluster, and field

Euclid Collaboration, A. Parmar, D. L. Clements +297

The MAMBO mock galaxy catalogue, based on the Millennium Simulation with empirically assigned galaxy properties, provides predictions of FIR fluxes and physical parameters of Eucli…

Euclid: The linear-construction covariance and cosmology

V. Lindholm, E. Sihvola, J. Valiviita +137

We study the properties of galaxy cluster 2-point correlation function covariance matrices estimated using the linear-construction (LC) method, which is computationally up to 20 ti…
