MassiveNuS: Cosmological Massive Neutrino Simulations

Jia Liu, Simeon Bird, José Manuel Zorrilla Matilla +5

The non-zero mass of neutrinos suppresses the growth of cosmic structure on small scales. Since the level of suppression depends on the sum of the masses of the three active neutri…

Search for Bosonic Super-WIMP Interactions with the XENON100 Experiment

XENON collaboration, E. Aprile, J. Aalbers +118

We present results of searches for vector and pseudo-scalar bosonic super-WIMPs, which are dark matter candidates with masses at the keV-scale, with the XENON100 experiment. XENON1…

Measurement of the thermal Sunyaev-Zel'dovich effect around cosmic voids

David Alonso, J. Colin Hill, Renée Hložek +1

We stack maps of the thermal Sunyaev-Zel'dovich effect produced by the Planck Collaboration around the centers of cosmic voids defined by the distribution of galaxies in the CMASS…

The uniformity and time-invariance of the intra-cluster metal distribution in galaxy clusters from the IllustrisTNG simulations

Mark Vogelsberger, Federico Marinacci, Paul Torrey +8

The distribution of metals in the intra-cluster medium encodes important information about the enrichment history and formation of galaxy clusters. Here we explore the metal conten…

First results from the IllustrisTNG simulations: radio haloes and magnetic fields

Federico Marinacci, Mark Vogelsberger, Rüdiger Pakmor +8

We introduce the IllustrisTNG project, a new suite of cosmological magnetohydrodynamical simulations performed with the moving-mesh code AREPO employing an updated Illustris galaxy…

Geometry and growth contributions to cosmic shear observables

José Manuel Zorrilla Matilla, Zoltán Haiman, Andrea Petri +1

We explore the sensitivity of weak lensing observables to the expansion history of the universe and to the growth of cosmic structures, as well as the relative contribution of both…

The Two-Halo Term in Stacked Thermal Sunyaev-Zel'dovich Measurements: Implications for Self-Similarity

J. Colin Hill, Eric J. Baxter, Adam Lidz +2

The relation between the mass and integrated electron pressure of galaxy group and cluster halos can be probed by stacking maps of the thermal Sunyaev-Zel'dovich (tSZ) effect. Perh…

Effective field theory search for high-energy nuclear recoils using the XENON100 dark matter detector

E. Aprile, J. Aalbers, F. Agostini +114

We report on WIMP search results in the XENON100 detector using a non-relativistic effective field theory approach. The data from science run II (34 kg 224.6 live days) wa…

Bias to CMB Lensing Reconstruction from Temperature Anisotropies due to Large-Scale Galaxy Motions

Simone Ferraro, J. Colin Hill

Gravitational lensing of the cosmic microwave background (CMB) is expected to be amongst the most powerful cosmological tools for ongoing and upcoming CMB experiments. In this work…

First Dark Matter Search Results from the XENON1T Experiment

E. Aprile, J. Aalbers, F. Agostini +122

We report the first dark matter search results from XENON1T, a 2000-kg-target-mass dual-phase (liquid-gas) xenon time projection chamber in operation at the Laboratori Nazion…

Search for magnetic inelastic dark matter with XENON100

XENON collaboration, E. Aprile, J. Aalbers +112

We present the first search for dark matter-induced delayed coincidence signals in a dual-phase xenon time projection chamber, using the 224.6 live days of the XENON100 science run…

Tests of Gravity Theories Using Supermassive Black Holes

Jeremy Sakstein, Bhuvnesh Jain, Jeremy S. Heyl +1

Scalar-tensor theories of gravity generally violate the strong equivalence principle, namely compact objects have a suppressed coupling to the scalar force, causing them to fall sl…

Search for Electronic Recoil Event Rate Modulation with 4 Years of XENON100 Data

The XENON collaboration, E. Aprile, J. Aalbers +111

We report on a search for electronic recoil event rate modulation signatures in the XENON100 data accumulated over a period of 4 years, from January 2010 to January 2014. A profile…

Hierarchical inference of the relationship between Concentration and Mass in Galaxy Groups and Clusters

Maggie Lieu, Will M. Farr, Michael Betancourt +3

Mass is a fundamental property of galaxy groups and clusters. In theory weak gravitational lensing will enable an approximately unbiased measurement of mass, but parametric methods…

Rethinking CMB foregrounds: systematic extension of foreground parameterizations

Jens Chluba, J. Colin Hill, Maximilian H. Abitbol

Future high-sensitivity measurements of the cosmic microwave background (CMB) anisotropies and energy spectrum will be limited by our understanding and modeling of foregrounds. Not…
