Lyman Break Galaxy selection and redshift measurement with supervised contrastive learning

J. Choppin de Janvry, C. Yèche, Arjun Dey +55

Some of the next steps for high-precision cosmology lie within the high-redshift, high-density universe. Spectroscopic survey experiments such as the Dark Energy Spectroscopic Inst…

Clustering of high-redshift quasars with DESI DR2

M. Charles, P. Martini, A. J. Ross +46

We present clustering measurements for high-redshift quasars using data from the Dark Energy Spectroscopic Instrument Data Release 2. Our sample consists of quasars with $2.0 < z <…

The PAU Survey and Euclid: Analysing photometric redshifts from realistically simulated narrow-band photometry with Flagship 2

A. Wittje, H. Hildebrandt, D. Navarro-Gironés +154

The study of the large-scale structure of the Universe and the distribution of galaxies has been greatly advanced by the application of various types of photometric redshift estima…

The 3D clustering of Lyman Alpha Emitters measured with DESI

Haruki Ebina, Martin J. White, Rongpu Zhou +44

We present a clustering analysis of Lyman- emitters (LAEs) using spectroscopic observations from the Dark Energy Spectroscopic Instrument (DESI) of candidates selected from the…

Measuring local primordial non-Gaussianity from the clustering of DESI DR1 LRGs and QSOs

Z. Brown, B. Levi, H. Randall +42

We report the first measurement of primordial non-Gaussianity (PNG), parameterized by , in the configuration space two-point correlation function (2pcf). We employ…

Cosmological constraints from the DESI DR1 Bispectrum Full-Shape and DR2 BAO

D. Forero-Sánchez, S. Novell-Masot, H. Gil-Marín +48

We present cosmological constraints from the combination of DESI DR1 full-shape measurements, including for the LRG bispectrum, and DESI DR2 BAO data. The joint analysis accounts f…
