Galaxy and Halo Assembly Bias in Alternative Dark Matter Models
Yikun Wang, Idit Zehavi, Sergio Contreras +6
The clustering of dark matter halos depends not only on halo mass but also on secondary halo properties, a phenomenon known as halo assembly bias. Coupled with variations in halo o…
The Impact of Splashback Galaxies on Galaxy Assembly Bias
Hernan Rincon, Idit Zehavi, Sergio Contreras +2
The clustering of galaxies is affected by the assembly history of their underlying dark matter halos. This complex phenomenon, known as galaxy assembly bias, has been extensively s…
Secondary Dependence of Baryonic Effects on the Density Profile of Dark Matter Halos
Yikun Wang, Idit Zehavi, Sergio Contreras +3
Baryonic physics is anticipated to be a major source of systematic uncertainty in current and future large-scale cosmological surveys. We investigate how baryonic effects on halo d…
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…
A New Measure of Assembly Bias using the Environment Dependence of the Luminosity Function
Yikun Wang, Idit Zehavi, Sergio Contreras +2
Assembly bias is the variation in the clustering of dark matter halos and galaxies that arises from correlations between the halo assembly history and the large-scale environment a…
Exploring the physical origins of halo assembly bias from early times
Antonio D. Montero-Dorta, Sergio Contreras, M. Celeste Artale +2
The large-scale linear halo bias encodes the relation between the clustering of dark-matter (DM) halos and that of the underlying matter density field. Although the primary depende…
