High sensitivity polarimetry : techniques and applications
(Springer Nature, 2010)
High sensitivity polarimetry will refer to fractional polarizations of below, and often significantly below, 103. Measuring low fractional polarization requires a large number of photons and also special techniques are ...
Magnetic field configuration at the galactic center investigated by wide-field near-infrared polarimetry : transition from a toroidal to a poloidal magnetic field
(2010)
We present a large-scale view of the magnetic field (MF) in the central 2° × 2° region of our Galaxy. The polarization of point sources has been measured in the J, H, and KS bands using the near-infrared polarimetric camera ...
Extended High Circular Polarization in the Orion Massive Star Forming Region: Implications for the Origin of Homochirality in the Solar System
(2010)
We present a wide-field (∼6′ × 6′) and deep near-infrared (K s band: 2.14 μm) circular polarization image in the Orion nebula, where massive stars and many low-mass stars are forming. Our results reveal that a high circular ...
The linear polarization of nearby bright stars measured at the parts per million level
(2010)
We report observations of the linear polarization of a sample of 49 nearby bright stars measured to sensitivities of between ∼1 and ∼ 4 × 10−6 . The majority of stars in the sample show measurable polarization, but most ...
