Weak Gravitational Lensing as a Method to Constrain Unstable Dark Matter
Mei-Yu Wang, Andrew R. Zentner
The nature of the dark matter remains a mystery. The possibility of an unstable dark matter particle decaying to invisible daughter particles has been explored many times in the pa…
Counts-in-Cylinders in the Sloan Digital Sky Survey with Comparisons to N-body Simulations
Heather D. Berrier, Elizabeth J. Barton, Joel C. Berrier +3
Environmental statistics provide a necessary means of comparing the properties of galaxies in different environments and a vital test of models of galaxy formation within the preva…
Galaxy Peculiar Velocities From Large-Scale Supernova Surveys as a Dark Energy Probe
Suman Bhattacharya, Arthur Kosowsky, Jeffrey A. Newman +1
Upcoming imaging surveys such as the Large Synoptic Survey Telescope will repeatedly scan large areas of sky and have the potential to yield million-supernova catalogs. Type Ia sup…
The distribution of annihilation luminosities in dark matter substructure
Savvas M. Koushiappas, Andrew R. Zentner, Andrey V. Kravtsov
We calculate the probability distribution function (PDF) of the expected annihilation luminosities of dark matter subhalos as a function of subhalo mass and distance from the Galac…
Shapes of Gas, Gravitational Potential and Dark Matter in Lambda-CDM Clusters
Erwin T. Lau, Daisuke Nagai, Andrey V. Kravtsov +1
We present analysis of the three-dimensional shape of intracluster gas in clusters formed in cosmological simulations of the Lambda-CDM cosmology and compare it to the shape of dar…
A General Study of the Influence of Catastrophic Photometric Redshift Errors on Cosmology with Cosmic Shear Tomography
Andrew P. Hearin, Andrew R. Zentner, Zhaoming Ma +1
A goal of forthcoming imaging surveys is to use weak gravitational lensing shear measurements to constrain dark energy. We quantify the importance of uncalibrated photometric redsh…
