Augmenting the \emph{WFIRST} microlensing campaigns with intensive observations from a ground-based network of wide-field survey telescopes would have several major advantages. First, it would enable...
View ArticleForeground-Induced Biases in CMB Polarimeter Self-Calibration [Replacement]
Precise polarisation measurements of the cosmic microwave background (CMB) require accurate knowledge of the instrument orientation relative to the sky frame used to define the cosmological Stokes...
View ArticleConsiderations on the microwave radiation emitted by extended air showers...
The emission of microwave radiation by extended air showers produced by high energy cosmic rays has been investigated for more than half a century. We discuss the expected emitted power as a function...
View ArticleThe impact of beam deconvolution on noise properties in CMB measurements:...
We present an analysis of the effects of beam deconvolution on noise properties in CMB measurements. The analysis is built around the artDeco beam deconvolver code. We derive a low-resolution noise...
View ArticleEnergy and Flux Measurements of Ultra-High Energy Cosmic Rays Observed During...
The first flight of the Antarctic Impulsive Transient Antenna (ANITA) experiment recorded 16 radio signals that were emitted by cosmic-ray induced air showers. For 14 of these events, this radiation...

We describe a tool we improved to detect excess noise in the gravitational wave (GW) channel arising from its bilinear or nonlinear coupling with fluctuations of various components of a GW...
View ArticleThe Science Case for ALMA Band 2 and Band 2+3
We discuss the science drivers for ALMA Band 2 which spans the frequency range from 67 to 90 GHz. The key science in this frequency range are the study of the deuterated molecules in cold, dense,...
