In this communication we present the first experimental results obtained on the Crossed-cubes nuller (CCN), that is a new type of Achromatic phase shifter (APS) based on a pair of crossed beamsplitter...
View ArticleAnalysis of nulling phase functions suitable to image plane coronagraphy
Coronagraphy is a very efficient technique for identifying and characterizing extra-solar planets orbiting in the habitable zone of their parent star, especially when used in a space environment. An...

After having demonstrated that an IFU, attached to a microscope rather than to a telescope, is capable of differentiating complex organic tissue with spatially resolved Raman spectroscopy, we have...
View ArticleDesign of 280 GHz feedhorn-coupled TES arrays for the balloon-borne...
We describe 280 GHz bolometric detector arrays that instrument the balloon-borne polarimeter SPIDER. A primary science goal of SPIDER is to measure the large-scale B-mode polarization of the cosmic...

We present a catalog of 624 radio sources detected around the North Celestial Pole (NCP) with the 21 Centimeter Array (21CMA), a radio interferometer dedicated to the statistical measurement of the...
View ArticleRedundant Array Configurations for 21 cm Cosmology [Replacement]
Realizing the potential of 21 cm tomography to statistically probe the intergalactic medium before and during the Epoch of Reionization requires large telescopes and precise control of systematics....

We use the first release of the VImos Public Extragalactic Redshift Survey of galaxies (VIPERS) of ~50,000 objects to measure the biasing relation between galaxies and mass in the redshift range...
View ArticleSurvey strategy optimization for the Atacama Cosmology Telescope
In recent years there have been significant improvements in the sensitivity and the angular resolution of the instruments dedicated to the observation of the Cosmic Microwave Background (CMB). ACTPol...
View ArticleHIRAX: A Probe of Dark Energy and Radio Transients
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a new 400-800MHz radio interferometer under development for deployment in South Africa. HIRAX will comprise 1024 six meter parabolic...
View ArticleAnalysis of the Very Inner Milky Way Dark Matter Distribution and Gamma-Ray...
We study the Dark Matter (DM) distribution in the inner Galactic Center region (< 100 pc) considering the extrapolation of a compilation of density profiles appearing in state-of-the-art N-body +...
View ArticleMICADO: first light imager for the E-ELT
MICADO will equip the E-ELT with a first light capability for diffraction limited imaging at near-infrared wavelengths. The instrument's observing modes focus on various flavours of imaging, including...
View ArticleTemplate matching method for the analysis of interstellar cloud structure
The structure of interstellar medium can be characterised at large scales in terms of its global statistics (e.g. power spectra) and at small scales by the properties of individual cores. Interest has...
View ArticleJUDE: An alternative UVIT pipeline
We have written a set of routines to convert the Level 1 data from UVIT into scientifically useful photon lists and images. These routines are in the GNU Data Language (GDL) and are compatible with the...
View ArticleA Monte-Carlo Method for Making SDSS $u$-Band Magnitude more accurate
We develop a new Monte-Carlo-based method to convert the SDSS (Sloan Digital Sky Survey) $u$-band magnitude to the SCUSS (South Galactic Cap of $u$-band Sky Survey) $u$-band magnitude. Due to more...
View ArticleOptical modeling and polarization calibration for CMB measurements with...
The Atacama Cosmology Telescope Polarimeter (ACTPol) is a polarization sensitive upgrade to the Atacama Cosmology Telescope. Located at an elevation of 5190 m, ACTPol measures the Cosmic Microwave...
