abstract

We carry out a test of the cosmic distance duality relation using a sample of 52 SPT-SZ clusters, along with X-ray measurements from XMM-Newton. To carry out this test, we need an estimate of the luminosity distance ($D_L$) at the redshift of the cluster. For this purpose, we use three independent methods: directly using $D_L$ from the closest Type Ia Supernovae from the Union 2.1 sample, non-parametric reconstruction of $D_L$ using the same Union 2.1 sample, and finally using $H(z)$ measurements from cosmic chronometers and reconstructing $D_L$ using Gaussian Process regression. We use four different functions to characterize the deviations from CDDR. All our results for these ($4 \times 3$) analyses are consistent with CDDR to within 1$\sigma$.

  1. Hubble tension: the shape wall

    astro-ph.CO 2026-07 accept novelty 6.0 of 10

    Late-time modifications to the expansion history can raise H0 by at most about 2% (conservative) to 3.7% (permissive) if the CMB acoustic scale is fixed.

  2. A Search for Hard X-ray/Soft $\gamma$-ray Emission from SPT-CL J2012-5649 (Abell 3667) Using INTEGRAL/ISGRI

    astro-ph.HE 2025-12 conditional novelty 5.0 of 10

    INTEGRAL/ISGRI finds no 30–300 keV emission from the merging galaxy cluster Abell 3667, yielding a 3σ upper limit of 4.4×10^-10 erg cm^-2 s^-1 in the 30–100 keV band.

  3. Constraints on Dark Energy Models Using Late Universe Probes

    astro-ph.CO 2025-06 conditional novelty 4.0 of 10

    Using late-universe probes only, the authors find all dark energy models remain within 1-2 sigma of Lambda CDM, which wins the Bayesian model comparison, and confirm that DESI's LRG1 and LRG2 points drive the dynamica...

  4. Cosmic distance duality after DESI 2024 data release and dark energy evolution

    astro-ph.CO 2025-01 conditional novelty 4.0 of 10

    Using DESI BAO, galaxy clusters, supernovae and Hubble data, the authors find no evidence for violation of the cosmic distance duality and favor flat ΛCDM.
