First planetesimals from DESI DR1: 12 highly metal-rich white dwarfs

Paula Izquierdo, Andrew Swan, Boris T. Gänsicke +43

The paper analyzes 12 highly metal‑rich white dwarfs from DESI DR1, measuring their photospheric metal abundances to infer the bulk composition of the accreted planetary debris, wh…

Early results in the search for extreme coronal line emitters with the Dark Energy Spectroscopic Instrument

Peter Clark, Joseph Callow, Or Graur +44

Here we present the results of our search through the Early Data Release (EDR) of the Dark Energy Spectroscopic Instrument (DESI) for extreme coronal line emitters (ECLEs) - a rare…

ODIN: Characterizing the Three-dimensional Structure of Two Protocluster Complexes at

Vandana Ramakrishnan, Ashley Ortiz, Byeongha Moon +52

We present a detailed study of the 3D morphology of two extended associations of multiple protoclusters at . These protocluster 'complexes', designated COSMOS-z3.1-A and COS…

Euclid Quick Data Release (Q1). The role of cosmic connectivity in shaping galaxy clusters

Euclid Collaboration, C. Gouin, C. Laigle +337

The matter distribution around galaxy clusters is distributed over several filaments, reflecting their positions as nodes in the large-scale cosmic web. The number of filaments con…

Euclid preparation. Decomposing components of the extragalactic background light using multi-band intensity mapping cross-correlations

Euclid Collaboration, Y. Cao, A. R. Cooray +269

The extragalactic background light (EBL) fluctuations in the optical/near-IR encode the cumulative integrated galaxy light (IGL), diffuse intra-halo light (IHL), and high- sourc…

Euclid preparation. XCVIII. Cosmology Likelihood for Observables in Euclid (CLOE). 5: Extensions beyond the standard modelling of theoretical probes and systematic effects

Euclid Collaboration, L. W. K. Goh, A. Nouri-Zonoz +301

Euclid is expected to establish new state-of-the-art constraints on extensions beyond the standard LCDM cosmological model by measuring the positions and shapes of billions of gala…
