The front-end optical design for band 9 (600 to 720GHz) of the Atacama Large Millimeter Array (ALMA) is now completed and verified. A frequency independent design approach is used to couple radiation to the two orthogonal polarized mixed detectors from the large 12m ALMA Cassegrain telescope. As it is a heterodyne receiver, two local oscillator beam paths are integrated into the front-end optic...

The People's Health Movement (PHM) is a global network of people oriented health professionals and activists, academcis and researchers, campaigners and people organizations that have actively promoted the re-endorsement of the 'Health for All' principles of the Alma Ata Declaration and the importance of social determinants of health and health care. The paper outlines a series of ongoing advoc...

The Onsala national facility's mission in astronomy is to support Swedish astronomers' access to telescopes operating between sub-millmetre and decametre wavelengths (a range of 100 000). This broad mission is illustrated in the articles in this newsletter, which feature plans for the deployment of a new sub-millimetre (Band 9) receiver for APEX, together with a report on the first SKA key scie...

The innermost regions of radio loud Active Galactic Nuclei (AGN) jets are heavily affected by synchrotron self-absorption, due to the strong magnetic fields and high particle densities in these extreme zones. The only way to overcome this absorption is to observe at sub-millimeter wavelengths, although polarimetric observations at such frequencies have so far been limited by sensitivity and cal...

Compact substructure is expected to arise in a starless core as mass becomes concentrated in the central region likely to form a protostar. Additionally, multiple peaks may form if fragmentation occurs. We present ALMA Cycle 2 observations of 60 starless and protostellar cores in the Ophiuchus molecular cloud. We detect eight compact substructures which are > 15 from the nearest Spitzer YSO. On...
