Revisiting the CMB homogeneity scale: low multipoles removal effect and extragalactic foreground masking
Xiaoyun Shao, Facundo Toscano, Diego Garcia Lambas +5
The Cosmic Microwave Background (CMB) reaches homogeneity at relatively modest angular scales compared to the expectation of the standard CDM model revealing an important chall…
VENUS: Strong-lensing model of MACS J1931.8-2635 -- revealing the farthest multiply imaged supernova
Joseph F. V. Allingham, Adi Zitrin, Vasily Kokorev +42
We present a parametric strong-lensing model for the galaxy cluster MACS J1931.8-2635 (), accompanying the detection of the spectroscopically confirmed SN Eos at $z = 5…
Hubble tension and small-scale inhomogeneities on light propagation
Lucila Kraiselburd, Cassio Pigozzo, Susana J. Landau +1
Context. A major observational challenge within the standard cosmological framework is the Hubble tension, a statistically significant () disagreement between the Hubble…
Dark Energy Survey: DESI-Independent Angular BAO Measurement
J. Mena-Fernández, S. Avila, A. Porredon +80
We present a measurement of the angular baryon acoustic oscillation (BAO) scale from the completed Dark Energy Survey (DES) dataset excluding the area of overlap with the Dark Ener…
Confirming the uniformity of the Hubble flow with Pantheon+ Supernovae
Xiaoyun Shao, Carlos A. P. Bengaly
According to the perturbed Friedmann model, the difference between Hubble constant measurements in two rest frames, at leading order in velocity, is determined solely by the relati…
Euclid preparation. LXXXIX. Accurate and precise data-driven angular power spectrum covariances
Euclid Collaboration, K. Naidoo, J. Ruiz-Zapatero +280
We develop techniques for generating accurate and precise internal covariances for measurements of clustering and weak-lensing angular power spectra. These methods have been design…
