High-fidelity reproduction of central galaxy joint distributions with Neural Networks

The relationship between galaxies and haloes is central to the description of galaxy formation, and a fundamental step towards extracting precise cosmological information from galaxy maps. However, this connection involves several complex processes t

On the kinetic Sunyaev–Zel’dovich effect as an observational probe for halo spin bias

Autor: M. Celeste Artale, Antonio D. Montero-Dorta, L. Raul Abramo, Beatriz Tucci

Publikováno v: Monthly Notices of the Royal Astronomical Society. 504:4568-4582

We explore the potential of the kinetic Sunyaev-Zel'dovich (kSZ) effect as the cornerstone of a future observational probe for halo spin bias, the secondary dependence of halo clustering on halo spin at fixed halo mass. Using the IllustrisTNG magneto

We use mock galaxy data from the VIMOS Public Extragalactic Redshift Survey (VIPERS) to test the performance of the Multi-Tracer Optimal Estimator (MTOE) of Abramo et al. as a tool to measure the monopoles of the power spectra of multiple tracers of

On the environmental influence of groups and clusters of galaxies beyond the virial radius: Galactic conformity at few Mpc scales

Autor: Ivan Lacerna, Facundo Rodriguez, Antonio D Montero-Dorta, Ana L O’Mill, Sofía A Cora, M Celeste Artale, Andrés N Ruiz, Tomás Hough, Cristian A Vega-Martínez

The environment within dark matter haloes can quench the star formation of galaxies. However, environmental effects beyond the virial radius of haloes ($\gtrsim$ 1 Mpc) are less evident. An example is the debated correlation between colour or star fo

We study the intrinsic large-scale distribution and evolution of seven ionized metals in the IllustrisTNG magneto-hydrodynamical cosmological simulation. We focus on the fractions of C\,\textsc{ii}, C\,\textsc{iv}, Mg\,\textsc{ii}, N\,\textsc{v}, Ne\
