Scaling relations between black holes and their host galaxies: comparing theoretical and observational measurements, and the impact of selection effects
Colin DeGraf, Tiziana Di Matteo, Tommaso Treu +3
We use the high-resolution simulation MassiveBlackII to examine scaling relations between black hole mass (MBH) and host galaxy properties (sigma, M*, and LV), finding good agreeme…
Risk diversification: a study of persistence with a filtered correlation-network approach
Nicoló Musmeci, Tomaso Aste, Tiziana Di Matteo
The evolution with time of the correlation structure of equity returns is studied by means of a filtered network approach investigating persistences and recurrences and their impli…
Intrinsic alignments of galaxies in the MassiveBlack-II simulation: analysis of two-point statistics
Ananth Tenneti, Sukhdeep Singh, Rachel Mandelbaum +3
The intrinsic alignment of galaxies with the large-scale density field is an important astrophysical contaminant in upcoming weak lensing surveys. We present detailed measurements…
The role of Compton heating in radiation-regulated accretion on to black holes
KwangHo Park, Massimo Ricotti, Tiziana Di Matteo +1
We investigate the role of Compton heating in radiation-regulated accretion on to black holes from a neutral dense medium using 1D radiation-hydrodynamic simulations. We focus on t…
Relation between Financial Market Structure and the Real Economy: Comparison between Clustering Methods
Nicolo Musmeci, Tomaso Aste, Tiziana Di Matteo
We quantify the amount of information filtered by different hierarchical clustering methods on correlations between stock returns comparing it with the underlying industrial activi…
Galaxy Shapes and Intrinsic Alignments in The MassiveBlack-II Simulation
Ananth Tenneti, Rachel Mandelbaum, Tiziana Di Matteo +2
The intrinsic alignment of galaxy shapes with the large-scale density field is a contaminant to weak lensing measurements, as well as being an interesting signature of galaxy forma…
The MassiveBlack-II Simulation: The Evolution of Halos and Galaxies to z~0
Nishikanta Khandai, Tiziana Di Matteo, Rupert Croft +5
(Abridged for arXiv)We investigate the properties of halos, galaxies and blackholes to z=0 in the high resolution hydrodynamical simulation MassiveBlack-II (MBII) which evolves a L…
