Galaxy-halo internal alignments across cosmic time
Agustina V. Marsengo-Colazo, Facundo Rodriguez, Manuel Merchán
Investigations of intrinsic alignments suggest a link between the alignment of a central galaxy's major axis with the galaxy distribution and its internal galaxy-halo shape alignme…
Spinning masters: on the impact of tidal forces and protohalo size on early spin evolution
Pablo López, Rien van de Weygaert, Manuel Merchán
In this work, we explore how the size and surrounding tidal fields of dark matter protohalos at high redshift influence their angular momentum (AM) evolution. While tidal torque th…
Central galaxy alignments. Dependence on the mass and the large-scale environment
Facundo Rodriguez, Manuel Merchán, Daniela Galárraga-Espinosa +4
Observations indicate that central galaxies show a significant alignment of their main shape axes with other galaxies in their group, as well as with the large-scale structure of t…
Evolution of central galaxy alignments in simulations
Facundo Rodriguez, Manuel Merchán, M. Celeste Artale
Observations suggest that red central galaxies align closely with their group galaxies and the large-scale environment.This finding was also replicated in simulations, which added…
