Non-Equilibrium Electrons and the Sunyaev-Zel'dovich Effect of Galaxy Clusters
Douglas H. Rudd, Daisuke Nagai
We present high-resolution cosmological hydrodynamic simulations of three galaxy clusters employing a two-temperature model for the intracluster medium. We show that electron tempe…
New Perspective on Galaxy Clustering as a Cosmological Probe: General Relativistic Effects
Jaiyul Yoo, A. Liam Fitzpatrick, Matias Zaldarriaga
We present a general relativistic description of galaxy clustering in a FLRW universe. The observed redshift and position of galaxies are affected by the matter fluctuations and th…
Possible Relic Lobes in Giant Radio Sources
S. Godambe, C. Konar, D. J. Saikia +1
We present low-frequency observations with the GMRT of three giant radio sources (J0139+3957, J0200+4049 and J0807+7400) with relaxed diffuse lobes which show no hotspots and no ev…
IRS Spectroscopy and Multi-wavelength Study of Luminous Star-forming Galaxies at z~1.9
J. -S. Huang, S. M. Faber, E. Daddi +24
We analyze a sample of galaxies chosen to have F24>0.5 mJy and satisfy a certain IRAC color criterion. IRS spectra yield redshifts, spectral types, and PAH luminosities, to which w…
The Population of Viscosity- and Gravitational Wave-Driven Supermassive Black Hole Binaries Among Luminous AGN
Zoltán Haiman, Bence Kocsis, Kristen Menou
Supermassive black hole binaries (SMBHBs) in galactic nuclei are thought to be a common by-product of major galaxy mergers. We use simple disk models for the circumbinary gas and f…
Towards the 2020 vision of the baryon content of galaxy groups and clusters
A. Kravtsov, A. Gonzalez, A. Vikhlinin +12
Groups and clusters of galaxies occupy a special position in the hierarchy of large-scale cosmic structures because they are the largest and the most massive (from ~10^13 Msun to o…
