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 secon…

Comparison of Cross-Correlation Methods for Line Intensity Mapping

Samuel H. Kramer, Patrick C. Breysse, Anthony R. Pullen +4

Line intensity mapping (LIM) is a technique for producing 3D maps of the Universe by scanning the sky with a spectrometer sensitive to a range of wavelengths corresponding to the r…

Fiducial-Cosmology-dependent systematics for the DESI 2024 Full-Shape Analysis

R. Gsponer, S. Ramirez-Solano, F. Rodríguez-Martínez +65

We assess the impact of the fiducial cosmology choice on cosmological inference from full-shape (FS) fits of the galaxy power spectrum in the DESI 2024 Data Release 1 (DR1). Using…

Robustness of pairwise kinematic Sunyaev-Zel'dovich effect to optical-cluster-selection bias

Y. -H. Hsu, D. Gruen, P. A. Gallardo +5

The pairwise kinematic Sunyaev-Zel'dovich(kSZ) effect measures both the pairwise motion between galaxy groups and clusters and the amount of gas within them, providing a tracer for…

DESI Strong Lens Foundry III: Keck Spectroscopy for Strong Lenses Discovered Using Residual Neural Networks

Shrihan Agarwal, Xiaosheng Huang, William Sheu +49

We present spectroscopic data of strong lenses and their source galaxies using the Keck Near-Infrared Echellette Spectrometer (NIRES) and the Dark Energy Spectroscopic Instrument (…

Forward analytical model for the optical selection bias on galaxy cluster lensing profiles

M. Costanzi, H. Y. Wu, J. H. Esteves +3

Cluster catalogs selected by optical properties are subject to selection biases, primarily arising from unresolved systems along the line of sight. These biases affect key observab…
