Euclid Quick Data Release (Q1). Exploring galaxy morphology across cosmic time through Sersic fits

Understand

We present the results of the single-component S\'ersic profile fitting for the magnitude-limited sample of \IE$<23$ galaxies within the 63.1 deg$^2$ area of the Euclid Quick Data Release (Q1).

• The associated morphological catalogue includes two sets of structural parameters fitted using \texttt{SourceXtractor++}: one for VIS \IE images and one for a combination of three NISP images in \YE, \JE and \HE bands.
• We compare the resulting S\'ersic parameters to other morphological measurements provided in the Q1 data release, and to the equivalent parameters based on higher-resolution \HST imaging.
• These comparisons confirm the consistency and the reliability of the fits to Q1 data.
