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…
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…
