Deconstructing Thermal Sunyaev-Zel'dovich - Gravitational Lensing Cross-Correlations: Implications for the Intracluster Medium
N. Battaglia, J. C. Hill, N. Murray
Recent first detections of the cross-correlation of the thermal Sunyaev-Zel'dovich (tSZ) signal in Planck cosmic microwave background (CMB) temperature maps with gravitational lens…
Cosmology Constraints from the Weak Lensing Peak Counts and the Power Spectrum in CFHTLenS
Jia Liu, Andrea Petri, Zoltan Haiman +3
Lensing peaks have been proposed as a useful statistic, containing cosmological information from non-Gaussianities that is inaccessible from traditional two-point statistics such a…
The Atacama Cosmology Telescope: Lensing of CMB Temperature and Polarization Derived from Cosmic Infrared Background Cross-Correlation
Alexander van Engelen, Blake D. Sherwin, Neelima Sehgal +47
We present a measurement of the gravitational lensing of the Cosmic Microwave Background (CMB) temperature and polarization fields obtained by cross-correlating the reconstructed c…
Evidence of Lensing of the Cosmic Microwave Background by Dark Matter Halos
Mathew Madhavacheril, Neelima Sehgal, Rupert Allison +40
We present evidence of the gravitational lensing of the cosmic microwave background by solar mass dark matter halos. Lensing convergence maps from the Atacama Cosmology T…
The origin of spin in galaxies: clues from simulations of atomic cooling halos
Joaquin Prieto, Raul Jimenez, Zoltán Haiman +1
In order to elucidate the origin of spin in both dark matter and baryons in galaxies, we have performed hydrodynamical simulations from cosmological initial conditions. We study at…
Precision Tests of Parity Violation Over Cosmological Distances
Jonathan Kaufman, Brian Keating, Brad Johnson
Recent measurements of the Cosmic Microwave Background -mode polarization power spectrum by the BICEP2 and POLARBEAR experiments have demonstrated new precision tools for probin…
The Stacked Thermal SZ Signal of Locally Brightest Galaxies in Planck Full Mission Data: Evidence for Galaxy Feedback?
Johnny P. Greco, J. Colin Hill, David N. Spergel +1
We use the Planck full mission temperature maps to examine the stacked thermal Sunyaev-Zel'dovich (tSZ) signal of 188042 "locally brightest galaxies'" (LBGs) selected from the Sloa…
The impact of spurious shear on cosmological parameter estimates from weak lensing observables
Andrea Petri, Morgan May, Zoltan Haiman +1
Residual errors in shear measurements, after corrections for instrument systematics and atmospheric effects, can impact cosmological parameters derived from weak lensing observatio…
Galaxy cluster scaling relations measured with APEX-SZ
A. N. Bender, J. Kennedy, P. A. R. Ade +30
We present thermal Sunyaev-Zel'dovich effect (SZE) measurements for 42 galaxy clusters observed at 150 GHz with the APEX-SZ experiment. For each cluster, we model the pressure prof…
First Axion Results from the XENON100 Experiment
The XENON100 Collaboration, E. Aprile, F. Agostini +87
We present the first results of searches for axions and axion-like-particles with the XENON100 experiment. The axion-electron coupling constant, , has been probed by exploi…
The Birth of a Galaxy - III. Propelling reionisation with the faintest galaxies
John H. Wise, Vasiliy G. Demchenko, Martin T. Halicek +4
Starlight from galaxies plays a pivotal role throughout the process of cosmic reionisation. We present the statistics of dwarf galaxy properties at z > 7 in haloes with masses up t…
A Measurement of the Cosmic Microwave Background B-Mode Polarization Power Spectrum at Sub-Degree Scales with POLARBEAR
The POLARBEAR Collaboration, P. A. R. Ade, Y. Akiba +71
We report a measurement of the B-mode polarization power spectrum in the cosmic microwave background (CMB) using the POLARBEAR experiment in Chile. The faint B-mode polarization si…
A No-Go Theorem for Direct Collapse Black Holes Without a Strong Ultraviolet Background
Eli Visbal, Zoltan Haiman, Greg L. Bryan
Explaining the existence of supermassive black holes (SMBHs) larger than at redshifts remains an open theoretical question. One possibility is that…
The impact of mechanical AGN feedback on the formation of massive early-type galaxies
Ena Choi, Jeremiah P. Ostriker, Thorsten Naab +2
We employ cosmological hydrodynamical simulations to investigate the effects of AGN feedback on the formation of massive galaxies with present-day stellar masses of $M_{stel} = 8.8…
The observable signature of late heating of the Universe during cosmic reionization
Anastasia Fialkov, Rennan Barkana, Eli Visbal
Models and simulations of the epoch of reionization predict that spectra of the 21-cm transition of atomic hydrogen will show a clear fluctuation peak, at a redshift and scale, res…
SPHGal: Smoothed Particle Hydrodynamics with improved accuracy for Galaxy simulations
Chia-Yu Hu, Thorsten Naab, Stefanie Walch +2
We present the smoothed-particle hydrodynamics implementation SPHGal, which combines some recently proposed improvements in GADGET. This includes a pressure-entropy formulation wit…
High-Redshift Star Formation in a Time-Dependent Lyman-Werner Background
Eli Visbal, Zoltan Haiman, Bryan Terrazas +2
The first generation of stars produces a background of Lyman-Werner (LW) radiation which can photo-dissociate molecular hydrogen, increasing the mass of dark matter halos required…
H_2 Suppression with Shocking Inflows: Testing a Pathway for Supermassive Black Hole Formation
Ricardo Fernandez, Greg L. Bryan, Zoltan Haiman +1
The presence of quasars at redshifts z > 6 indicates the existence of supermassive black holes (SMBHs) as massive as a few times 10^9 Msun, challenging models for SMBH formation. O…
The Right Side of Einstein's Equation
Edward A Spiegel
Recent developments in observational cosmology have led to attempts to make modifications on both sides of the Einstein equation to explain some of the puzzling new findings. What…
Evolution in the Escape Fraction of Ionizing Photons and the Decline in Strong Lya Emission from z>6 Galaxies
Mark Dijkstra, Stuart Wyithe, Zoltan Haiman +2
The rapid decline in the number of strong Lyman Alpha (Lya) emitting galaxies at z > 6 provides evidence for neutral hydrogen in the IGM, but is difficult to explain with plausible…
