Compact Size, High SFR: Defining Morphological Features of Ly-Emitters
Keunho Kim, Anahita Alavi, Christopher Snapp-Kolas +7
The mechanisms of Ly photon escape are key to understanding galaxy evolution and cosmic reionization, yet remain poorly understood. We investigate the UV-continuum sizes of 23…
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…
A gradient boosting and broadband approach to finding Lyman-α emitting galaxies beyond narrowband surveys
A. Vale, A. Paulino-Afonso, A. Humphrey +5
In this work, we test whether gradient-boosting algorithms, trained on broadband photometric data from traditional Lyman- emitting (LAE) surveys, can efficiently and accurately…
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…
Through the fog: a complementary optical galaxy classification scheme for 'intermediate' redshifts
Duarte Muñoz Santos, Cirino Pappalardo, Henrique Miranda +10
Understanding galaxy classification depends on our interpretation of their spectra. To date, the hydrogen Balmer lines remain the most consistent way to classify galaxies, but at '…
Importance of modelling the nebular continuum in galaxy spectra
Henrique Miranda, Ciro Pappalardo, José Afonso +7
The neglect of modelling both stellar and nebular emission significantly affects the derived physical properties of galaxies, particularly those with high star formation rates. Whi…
