Improved constraints on the Milky Way potential using the M68 stream and DESI spectroscopic data
Carles G. Palau, Wenting Wang, Jiaxin Han +41
We present a selection of stars belonging to the stellar stream of the M68 (NGC 4590) globular cluster, also known as Fjörm. This star selection is an improvement on previous ones…
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…
Quiescent Host Galaxies of Extended Quasars Revealed by Spectrophotometric Decomposition
Shengxiu Sun, Linhua Jiang, Zhiwei Pan +27
Previous works of low-redshift quasar host galaxies have focused on compact quasars and found that their host galaxies are mainly star-forming galaxies. Here we present a study of…
Lyman- forest holography: 3D predictions from 1D measurements
J. Chaves-Montero, A. Font-Ribera, J. Aguilar +68
The paper introduces ForestFlow, an emulator that connects one‑dimensional Lyman‑α forest flux power spectrum measurements to three‑dimensional clustering predictions, enabling com…
CoLoRe-2LPT: Lyman- mock catalogues for the validation of DESI cosmological analyses
M. F. Ruiz-Herrera Bernal, S. Avila, A. Font-Ribera +90
The paper presents fast Lyman‑α forest mock catalogues generated with second‑order Lagrangian perturbation theory (2LPT) that accurately reproduce small‑scale clustering, BAO broad…
Validation of the DESI DR2 Ly forest full-shape analysis
M. Herbold, A. Cuceu, P. Martini +107
The paper validates the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 analysis of the Lyman‑α forest, focusing on extracting the Alcock‑Paczynski (AP) measurement from…
