ELGLRG distribution through dark matter halo dynamics
Ginevra Favole, Francisco-Shu Kitaura, Boryana Hadzhiyska +3
We investigate the clustering and halo occupation distribution (HOD) of DESI Y1 emission-line (ELGs) and luminous red (LRGs) galaxies at , including their cross-correlat…
Tracing the high-z cosmic web with Quaia: catalogues of voids and clusters in the quasar distribution
Nestor Arsenov, Andras Kovacs, Mar Perez Sar +5
Understanding the formation and evolution of the cosmic web of galaxies is a fundamental goal of cosmology, using various tracers of the cosmic large-scale structure at an ever wid…
Fast and accurate Gaia-unWISE quasar mock catalogs from LPT and Eulerian bias
Francesco Sinigaglia, Francisco-Shu Kitaura, Mahlet Shiferaw +3
We present full-sky quasar spectrophotometric mock catalogs with smooth redshift evolution from to , tailored to analyze the Gaia-unWISE Quasar Catalog (Quaia)…
Differentiable Fuzzy Cosmic-Web for Field Level Inference
P. Rosselló, F. -S. Kitaura, D. Forero-Sánchez +2
A comprehensive analysis of the cosmological large-scale structure derived from galaxy surveys involves field-level inference, which requires a forward modelling framework that sim…
New insight into the variability of the Be star Aquarii: Determination of stellar and disk parameters
D. Concha, C. Arcos, D. Turis-Gallo +4
The Be star Aquarii shows peculiar Cas-type X-ray emission, likely caused by its outer disk interacting with a low-mass companion, probably a white dwarf. We study the long…
