We present an overview of future observational facilities that will significantly enhance our understanding of the fundamental nature of dark matter. These facilities span a range…
Chandra Follow-Up of the SDSS DR8 redMaPPer Catalog Using the MATCha Pipeline
Devon L. Hollowood, Tesla Jeltema, Xinyi Chen +15
In order to place constraints on cosmology through optical surveys of galaxy clusters, one must first understand the properties of those clusters. To this end, we introduce the Mas…
On the relative bias of void tracers in the Dark Energy Survey
G. Pollina, N. Hamaus, K. Paech +61
Luminous tracers of large-scale structure are not entirely representative of the distribution of mass in our Universe. As they arise from the highest peaks in the matter density fi…

We combine Dark Energy Survey Year 1 clustering and weak lensing data with Baryon Acoustic Oscillations (BAO) and Big Bang Nucleosynthesis (BBN) experiments to constrain the Hubble…
Cosmic Voids and Void Lensing in the Dark Energy Survey Science Verification Data
C. Sánchez, J. Clampitt, A. Kovacs +69
Galaxies and their dark matter halos populate a complicated filamentary network around large, nearly empty regions known as cosmic voids. Cosmic voids are usually identified in spe…
Cosmology constraints from shear peak statistics in Dark Energy Survey Science Verification data
T. Kacprzak, D. Kirk, O. Friedrich +81
Shear peak statistics has gained a lot of attention recently as a practical alternative to the two point statistics for constraining cosmological parameters. We perform a shear pea…
A Dark Energy Camera Search for an Optical Counterpart to the First Advanced LIGO Gravitational Wave Event GW150914
M. Soares-Santos, R. Kessler, E. Berger +112
We report initial results of a deep search for an optical counterpart to the gravitational wave event GW150914, the first trigger from the Advanced LIGO gravitational wave detector…
Joint Measurement of Lensing-Galaxy Correlations Using SPT and DES SV Data
E. J. Baxter, J. Clampitt, T. Giannantonio +75
We measure the correlation of galaxy lensing and cosmic microwave background lensing with a set of galaxies expected to trace the matter density field. The measurements are perform…
Cross-correlation of gravitational lensing from DES Science Verification data with SPT and Planck lensing
D. Kirk, Y. Omori, A. Benoit-Lévy +89
