Euclid: Forecasting the number counts of bright line emitters in the Euclid Wide Survey and Euclid Deep fields
Euclid Collaboration, P. Cassata, S. Quai +308
The Euclid mission will revolutionize our understanding of the visible Universe by collecting images and spectra of millions of galaxies across cosmic time and environments. Here,…
Euclid. Predicting scaling relations for emission-line galaxies using simulated data
Euclid Collaboration, C. Mancini, L. Gabarra +317
The Euclid spectroscopic surveys will substantially increase the number of observed emission-line galaxies. We assess the ability of the Euclid Wide Survey (EWS) and Euclid Deep Su…
Euclid Quick Data Release (Q1). Mass-to-light ratio of elliptical galaxies: constraints from strong lensing
Euclid Collaboration, A. Sonnenfeld, A. Nersesian +312
Mass is among the most fundamental properties describing a galaxy. The relation between the luminosity and the total mass of a galaxy contains information on the efficiency of the…
k-Submodular Cover Problem with a Matroid Constraint
Xinru Li, Donglei Du, Qian Liu +2
We investigate k-submodular cover problem with a matroid constraint on an n-element ground set V , which seeks k disjoint subsets of V with minimal cost, where their union is an in…
Euclid Quick Data Release (Q1). Exploring the complexity of quenching processes across time, environment, and mass through recently quenched galaxies
Euclid Collaboration, Z. Mao, L. Pozzetti +308
Recently quenched galaxies (RQGs) provide insights into galaxy quenching. We present a photometric and spectroscopic analysis of RQGs using the first Euclid Quick Data Release (Q1)…
Precise QCD Predictions for the Scotogenic Model at Colliders

Motivated by the anticipated data rates of the high-luminosity phase of the Large Hadron Collider, we report the first predictions up to next-to-leading order in quantum chromodyna…
Euclid: Quick Data Release (Q1) -- Optical hotspots in powerful radio galaxies
M. J. Hardcastle, L. Bisigello, M. Bondi +154
The hotspots of powerful radio galaxies are the sites of high-energy particle acceleration, but radio observations give us limited information on the electron energy distributions…
Euclid Quick Data Release (Q1) Euclid spectroscopy of quasars. 2. Physical properties from spectral fitting
Euclid Collaboration, J. Calhau, G. Calderone +312
A substantial volume of spectroscopic data has become available with the Euclid Data Release (Q1), which represents a unique opportunity to study quasars (QSOs) in the Euclid Deep…
