Euclid. ERO. Galaxy morphology and photometry
Listed in IVOA Registry (Virtual Observatory)
The background galaxies in Euclid Early Release Observations images of the Perseus cluster make up a remarkable sample in its combination of 0.57deg^2^ area, 25.3 and 23.2 AB mag depth, as well as 0.1" and 0.3" angular resolutions, in optical and near-IR bands, respectively.
Description
Towards characterising the history of the Hubble sequence, we perform a morphological analysis of 2445 and 12786 galaxies with I_E_<=21 and I_E_<23, respectively.
We use single-Sersic profiles and the sums of a Sersic bulge and an exponential disc to model these galaxies with SourceXtractor++ and analyse their parameters in order to assess their consistencies and discrepancies. The fitted galaxies to I_E_<=21 span the various Hubble types with ubiquitous bulge and disc components, and a bulge-to-total light ratio B/T taking all values from 0 to 1. This analysis demonstrates the usefulness and limitations of single-Sersic profile modelling, and the power of bulge-disc decomposition for reliably characterising the morphology of lenticulars and spirals in Euclid images.

We make available the catalogues of best-fit parameters for the morphological and SED fits.
