Redshift Duality with Pantheon+SH0ES in a Planck-anchored Flat CDM Framework: Implications for Hubble Tension and Observational Inference

Tae-Kyoung Lee

We test an operationally defined redshift duality in which the observed redshift comprises the standard metric-expansion component together with an additional line-of-sight quantum…

DESI DR2 Baryon Acoustic Oscillations from the Lyman Alpha Forest Multipoles

N. G. Karaçaylı, A. Cuceu, J. Aguilar +55

We present an alternative measurement of the Baryon Acoustic Oscillation (BAO) using the Legendre multipole representation of the Ly forest correlation functions from the second…

Emulating galaxy and peculiar velocity clustering on non-linear scales

T. Dumerchat, J. Bautista, C. Ravoux +37

We explore the potential of cross-correlating galaxies and peculiar velocities on non-linear scales to enhance cosmological constraints. Leveraging the \textsc{AbacusSummit} simula…

Forecast on Gravity with HI 21cm Intensity Mapping Surveys

Yanling Song, Yu Sang, Linfeng Xiao +1

Modified gravity theories offer a well-motivated extension of General Relativity and provide a possible explanation for the late-time accelerated expansion of the Universe. Among t…

The DESI DR1 Peculiar Velocity Survey: growth rate measurements from the maximum likelihood fields method

Y. Lai, C. Howlett, J. Aguilar +60

We present the constraint on the growth rate of structure from the combination of DESI DR1 BGS sample, Fundamental Plane, and Tully-Fisher peculiar velocity catalogues using the ma…

Parity-odd Four-Point Correlation Function from DESI Data Release 1 Luminous Red Galaxy Sample

J. Hou, R. N. Cahn, J. Aguilar +33

The parity-odd four-point function provides a unique probe of fundamental symmetries and potential new physics in the large-scale structure of the Universe. We present measurements…
