Constraints on Cosmology from the Cosmic Microwave Background Power Spectrum of the 2500 SPT-SZ Survey
Z. Hou, C. L. Reichardt, K. T. Story +49
We explore extensions to the CDM cosmology using measurements of the cosmic microwave background (CMB) from the recent SPT-SZ survey, along with data from WMAP7 and measurements…
Trans-Planckian Issues for Inflationary Cosmology
Robert Brandenberger, Jerome Martin
The accelerated expansion of space during the period of cosmological inflation leads to trans-Planckian issues which need to be addressed. Most importantly, the physical wavelength…
The SCUBA-2 Cosmology Legacy Survey: blank-field number counts of 450um-selected galaxies and their contribution to the cosmic infrared background
J. E. Geach, E. L. Chapin, K. E. K. Coppin +50
The first deep blank-field 450um map (1-sigma~1.3mJy) from the SCUBA-2 Cosmology Legacy Survey (S2CLS), conducted with the James Clerk Maxwell Telescope (JCMT) is presented. Our ma…
Super-luminous supernovae at redshifts of 2.05 and 3.90
Jeff Cooke, Mark Sullivan, Avishay Gal-Yam +6
A rare class of `super-luminous' supernovae that are about ten or more times more luminous at their peaks than other types of luminous supernovae has recently been found at low to…
Number Counts and Non-Gaussianity
Sarah Shandera, Adrienne L. Erickcek, Pat Scott +1
We describe a general procedure for using number counts of any object to constrain the probability distribution of the primordial fluctuations, allowing for generic weak non-Gaussi…
Lensing Noise in mm-wave Galaxy Cluster Surveys
Yashar Hezaveh, Keith Vanderlinde, Gilbert Holder +1
We study the effects of gravitational lensing by galaxy clusters of the background of dusty star-forming galaxies (DSFGs) and the Cosmic Microwave Background (CMB), and examine the…
