Modeling the HI-Halo Connection: Evolution, Scatter, and a Halo-based Prescription for 21-cm Mock Catalogs

Mohd Kamran, Gabriella De Lucia, Marta Spinelli +3

The redshifted 21-cm line of neutral hydrogen (HI) is a powerful tracer of large-scale structure, and post-reionization HI intensity mapping is emerging as a competitive cosmologic…

Euclid: Inferring star-formation history via cross-correlations of photometric clustering and shear with the cosmic infrared background

J. Han, S. Camera, M. Migliaccio +146

The cosmic infrared background, sourced by dust heated by star-forming activity, encodes the integrated history of the star-formation distribution over a large swathe of cosmic tim…

Star formation powers optical line emission from the CGM

Huanian Zhang, Lizhi Xie, Zhijie Qu +9

Using integral field spectroscopy, we explore the disk-halo interface, or the inner circumgalactic medium (CGM), of individual galaxies by constructing and analyzing emission-line…

Euclid: Calibrating distances from surface brightness fluctuations with Early Release Observations of the Fornax cluster

R. Habas, M. Cantiello, G. Riccio +169

Surface brightness fluctuations (SBF), the pixel-to-pixel variations in flux that arise from the statistical distribution of stars in galaxy images, provide a powerful tool to meas…

Euclid Quick Data Release (Q1). The average far-infrared properties of Euclid-selected star-forming galaxies

Euclid Collaboration, R. Hill, A. Abghari +302

The first Euclid Quick Data Release contains millions of galaxies with excellent optical and near-infrared (IR) coverage. To complement this dataset, we investigate the average far…

Origins of Extreme Emission-Line Ratios in z > 3 Galaxies: Insights from the Lumen Model

Lucie Scharré, Michaela Hirschmann, Adèle Plat +10

Optical emission-line ratios in star-forming galaxies at -8, such as [OIII]/H and [OIII]/[OII], are strongly offset from those at -2, pointing to more extre…
