The instrumental polarization of the Nasmyth focus polarimetric differential imager NAOS/CONICA (NACO) at the VLT - Implications for time-resolved polarimetric measurements of Sgr A*
the Nasmyth focus polarimetric differential imager NAOS/CONICA (NACO)
2011/1/10
We report on the results of calibrating and simulating the instrumental polarization properties of the ESO VLT adaptive optics camera system NAOS/CONICA (NACO) in the Ks-band. We use the Stokes/Muelle...

2011/1/11
An ultra-high-energy cosmic ray (UHECR) colliding with the Earth's atmosphere gives rise to an Extensive Air Shower (EAS). Due to different charge separation mechanisms within the thin shower front co...
The new generation CMB B-mode polarization experiment: POLARBEAR
new generation CMB B-mode polarization experiment
2010/11/10
We describe the Cosmic Microwave Background (CMB) polarization experiment called Po-larbear. This experiment will use the dedicated Huan Tran Telescope equipped with a powerful 1,200-bolometer array r...

2010/11/9
The observational expectation of polarization measurements of thermal dust ra-diation is investigated to find information on molecular outflows based on magne-tohydrodynamical (MHD) and radiation tran...
Stokes tomography of radio pulsar magnetospheres. I. Linear polarization
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/4
Polarimetric studies of pulsar radio emission traditionally concentrate on how the Stokes vector (I, Q, U, V) varies with pulse longitude, with special emphasis on the position angle (PA) swing of the...
An uncombed inversion of multi-wavelength observations reproducing the Net Circular Polarization in a sunspots' penumbra
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
I derived a geometrical model of the penumbral magnetic field topology from an uncombed inversion setup that aimed at reproducing the NCP of simultaneous spectra in near-IR (1.56 mu) and VIS (630 nm) ...
Improved Dark Energy Detection through the Polarization-assisted WMAP-NVSS ISW Correlation
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
Integrated Sachs-Wolfe (ISW) effect can be estimated by cross-correlating Cosmic Microwave Background (CMB) sky with tracers of the local matter distribution.
Using Absorptive Linear Polarization Spectroscopy to Understand Imbedded Stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
Sensitive measurements of the linearly polarized spectra of stars can be used to deduce geometric properties of their otherwise unresolved circumstellar environments. This paper describes some of the ...
Delensing CMB Polarization with External Datasets
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/22
One of the primary scientific targets of current and future CMB polarization experiments is the search for a stochastic background of gravity waves in the early universe. As instrumental sensitivity i...
Last scattering, relic gravitons and the circular polarization of the CMB
relic gravitons circular polarization
2010/3/19
The tensor contribution to the $V$-mode polarization induced by a magnetized plasma at last scattering vanishes exactly. Conversely a polarized background of relic gravitons cannot generate a $V$-mode...
