Angular momentum evolution in the CIELO simulations. I. Temporal evolution of gas-stellar misalignments and baryonic merger timing

Catalina Casanueva-Villarreal, Patricia B. Tissera, Nelson Padilla +4

Gas-stellar kinematic misalignments trace how galaxies assemble and reorient their angular momentum. Although well documented locally, their continuous evolution remains largely un…

The heartbeat of stellar halos: Insights from the stellar halo mass-metallicity relation

Jenny Gonzalez-Jara, Patricia B. Tissera, Antonela Monachesi +5

This work investigates the presence and evolution of the MZhR from redshift z=3.5 to z=0, and identifies when galaxies settle on the present-day MZhR. We used central galaxies with…

Primordial black holes as dark matter candidates: Multi-frequency constraints from cosmic radiation backgrounds

C. Casanueva-Villarreal, N. Padilla, P. B. Tissera +2

Aims. This study investigates the role of primordial black holes (PBHs) in shaping cosmic radiation backgrounds--the cosmic X-ray background (CXB), the Lyman-Werner background (LWB…

Insight into the physical processes that shape the metallicity profiles in galaxies

Brian Tapia-Contreras, Patricia B. Tissera, Emanuel Sillero +6

The distribution of chemical elements in the star-forming regions can store information on the chemical enrichment history of the galaxies. Negative metallicity gradients are expec…

The CIELO Project: The Chemo-dynamical properties of gaLaxies and the cosmic web

Patricia Tissera, Lucas Bignone, Jenny Gonzalez-Jara +13

The CIELO project introduces a novel set of chemo-dynamical zoom-in simulations designed to simultaneously resolve galaxies and their nearby environments. The initial conditions in…

Impact of Primordial Black Hole Dark Matter on Gas Properties at Very High Redshift: A Semi-Analytical Model

C. Casanueva-Villarreal, P. B. Tissera, N. Padilla +5

Context. Primordial black holes (PBHs) have been proposed as potential candidates for dark matter (DM) and have garnered significant attention in recent years. Aims. Our objective…
