The EROS project (Expérience de Recherche d'Objets Sombres) carried out photometric surveys of dense stellar fields towards the Magellanic Clouds (LMC and SMC), the Galactic Bulge…
Euclid preparation. Review of forecast constraints on dark energy and modified gravity
Euclid Collaboration, N. Frusciante, M. Martinelli +326
The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the…
Statistics of the projected angles between the black-hole spin and the host-galaxy rotation axes from NewHorizon
Sebastien Peirani, Yasushi Suto, Clotilde Laigle +3
Understanding the alignment between AGN jets and their host galaxies is crucial for interpreting AGN unification models, jet feedback processes, and the co-evolution of galaxies an…
Euclid Quick Data Release (Q1). From simulations to sky: Advancing machine-learning lens detection with real Euclid data
Euclid Collaboration, N. E. P. Lines, T. E. Collett +301
In the era of large-scale surveys like Euclid, machine learning has become an essential tool for identifying rare yet scientifically valuable objects, such as strong gravitational…
The DESI DR1 Peculiar Velocity Survey: Mock Catalog
J. Bautista, A. J. Amsellem, V. Aronica +59
We describe the production of the official set of mock catalogs for the Dark Energy Spectroscopic Instrument Peculiar Velocity Survey (DESI-PV) Data Release 1 (DR1). Our mock catal…
The DESI DR1 Peculiar Velocity Survey: The Tully-Fisher Distance Catalog
K. Douglass, S. BenZvi, A. G. Kim +64
We calibrate the Tully-Fisher relation (TFR) using observations of spiral galaxies taken during the first year (DR1) of the DESI galaxy redshift survey. The rotational velocities o…
On the Origin of Gas-stripping of Galaxies in Group Environments
Jinsu Rhee, Christophe Pichon, Yohan Dubois +12
We investigate how low-mass group environments () influence the gas content of their satellite galaxies with using…
Infrared emission from quasar host galaxies: a direct estimate of dust physical properties
M. Costa, R. Decarli, F. Pozzi +6
Quasars at the dawn of Cosmic Time () are fundamental probes to investigate the early co-evolution of supermassive black holes and their host galaxy. Nevertheless, their infra…
The Composite Spectrum of QSO Absorption Line Systems in DESI DR2
Lucas Napolitano, Adam D. Myers, Adam Tedeschi +43
We present details regarding a composite spectrum of quasar (QSO) absorption line systems. In this composite spectrum we identify more than 70 absorption lines, and observe oxygen…
Primordial Black-Hole-Based Pathways to Little Red Dots
Valerio De Luca, Loris Del Grosso, Gabriele Franciolini +4
The James Webb Space Telescope has uncovered a population of compact, high-redshift sources, the Little Red Dots (LRDs), which may host supermassive black holes (BHs) significantly…
Measurements of quasar proximity zones with the Ly forest of DESI Y1 quasars
Ryuichiro Hada, Paul Martini, David H. Weinberg +41
The intergalactic medium (IGM) around quasars is shaped by their dense environments and by their excess ionizing radiation, forming a "quasar proximity zone" whose size and anisotr…
