Testing Primordial Black Hole Dark Matter with ALMA Observations of the Gravitational Lens B1422+231
Di Wen, Athol J. Kemball
We examine the flux density ratio anomaly in the quadruply-imaged strong gravitational lens, B1422+231, and consider the contribution of primordial black holes (…
PS J1721+8842: A gravitationally lensed dual AGN system at redshift 2.37 with two radio components
C. S. Mangat, J. P. McKean, R. Brilenkov +4
Dual-Active Galactic Nuclei (AGN) are a natural consequence of the hierarchical structure formation scenario, and can provide an important test of various models for black hole gro…
Halo Counts-in-cells for Cosmological Models with Different Dark Energy
Di Wen, Athol J. Kemball, William C. Saslaw
We examine the counts-in-cells probability distribution functions that describe dark matter halos in the Dark Energy Universe Simulations (DEUS). We describe the measurements betwe…
Detection of lensing substructure using ALMA observations of the dusty galaxy SDP.81
Yashar D. Hezaveh, Neal Dalal, Daniel P. Marrone +13
We study the abundance of substructure in the matter density near galaxies using ALMA Science Verification observations of the strong lensing system SDP.81. We present a method to…
