Angular momentum and clustering properties of early dark matter halos
Andrew J. Davis, Priyamvada Natarajan
In this paper we study the angular momentum properties of simulated dark matter halos at high redshift that likely host the first stars in the Universe. Calculating the spin distri…
The abundance of lensing protoclusters
Anson D'Aloisio, Steven R. Furlanetto, Priyamvada Natarajan
Weak gravitational lensing provides a potentially powerful method for the detection of clusters. In addition to cluster candidates, a large number of objects with possibly no optic…
Is there an upper limit to black hole masses?
Priyamvada Natarajan, Ezequiel Treister
We make a case for the existence for ultra-massive black holes (UMBHs) in the Universe, but argue that there exists a likely upper limit to black hole masses of the order of $M \si…
MOND plus classical neutrinos not enough for cluster lensing
Priyamvada Natarajan, Hongsheng Zhao
Clusters of galaxies offer a robust test bed for probing the nature of dark matter that is insensitive to the assumption of the gravity theories. Both Modified Newtonian Dynamics (…
The Observatory for Multi-Epoch Gravitational Lens Astrophysics (OMEGA)
Leonidas A Moustakas, Adam J Bolton, Jeffrey T Booth +15
(abridged) The Observatory for Multi-Epoch Gravitational Lens Astrophysics (OMEGA) is a mission concept for a 1.5-m near-UV through near-IR space observatory that will be dedicated…
WMAP5 and the Cluster Mass Function
Kenneth Rines, Antonaldo Diaferio, Priyamvada Natarajan
The recently revised cosmological constraints from the Five-Year WMAP data ameliorate previous tension between cosmological constraints from the microwave background and from clust…
