Dark Energy Constraints from Galaxy Cluster Peculiar Velocities
Suman Bhattacharya, Arthur Kosowsky
Future multifrequency microwave background experiments with arcminute resolution and micro-Kelvin temperature sensitivity will be able to detect the kinetic Sunyaev-Zeldovich (kSZ)…
Effects of Quasar Feedback in Galaxy Groups
Suman Bhattacharya, Tiziana Di Matteo, Arthur Kosowsky
We study the effect of quasar feedback on distributions of baryons and properties of intracluster medium in galaxy groups using high-resolution numerical simulations. We use the en…
The Spectrum of Gravitational Radiation from Primordial Turbulence
Grigol Gogoberidze, Tina Kahniashvili, Arthur Kosowsky
Energy injection into the early universe can induce turbulent motions of the primordial plasma, which in turn act as a source for gravitational radiation. Earlier work computed the…
Milgrom Relation Models for Spiral Galaxies from Two-Dimensional Velocity Maps
Eric I. Barnes, Arthur Kosowsky, Jerry A. Sellwood
Using two-dimensional velocity maps and I-band photometry, we have created mass models of 40 spiral galaxies using the Milgrom relation (the basis of modified Newtonian dynamics, o…
The Sunyaev-Zeldovich Effect from Quasar Feedback
Suchetana Chatterjee, Arthur Kosowsky
The observed relationship between X-ray luminosity and temperature of the diffuse intercluster medium clearly shows the effect of nongravitational heating on the formation of galax…
