NIKA 150 GHz polarization observations of the Crab nebula and its spectral energy distribution
A. Ritacco, J. F. Macías Pérez, N. Ponthieu +45
The Crab nebula is a supernova remnant exhibiting a highly polarized synchrotron radiation at radio and millimeter wavelengths. It is the brightest source in the microwave sky with…
Observing the Sun with Atacama Large Millimeter/submillimeter Array (ALMA): High Resolution Interferometric Imaging
M. Shimojo, T. S. Bastian, A. S. Hales +25
Observations of the Sun at millimeter and submillimeter wavelengths offer a unique probe into the structure, dynamics, and heating of the chromosphere; the structure of sunspots; t…
Submillimeter Polarimetry with PolKa, a reflection-type modulator for the APEX telescope
Helmut Wiesemeyer, Talayeh Hezareh, Ernst Kreysa +6
Imaging polarimetry is an important tool for the study of cosmic magnetic fields. In our Galaxy, polarization levels of a few up to 10\% are measured in the submillimeter dus…
Non-Zeeman Circular Polarization of CO rotational lines in SNR IC 443
Talayeh Hezareh, Helmut Wiesemeyer, Martin Houde +2
Context: We investigate non-Zeeman circular polarization and linear polarization levels of up to 1% of CO spectral line emission detected in a shocked molecular clump around…
The unusual afterglow of the Gamma-Ray Burst 100621A
J. Greiner, T. Krühler, M. Nardini +27
In order to constrain the broad-band spectral energy distribution of the afterglow of GRB 100621A, dedicated observations were performed in the optical/near-infrared with the 7-cha…
APEX sub-mm monitoring of gamma-ray blazars
S. Larsson, L. Fuhrmann, A. Weiss +13
So far, no systematic long-term blazar monitoring programs and detailed variability studies exist at sub-mm wavelengths. Here, we present a new sub-mm blazar monitoring program usi…
