EISCAT observations of plasma patches at sub-auroral cusp latitudes
A sequence of 3 patches of high-density (1012 m−3) cold plasma on a horizontal scale-size of 300– 700 km was observed near magnetic noon by the EISCAT VHF radar above Svalbard on 17 December 2001. The patches followed a trajectory towards the cusp inflow region. The combination of radar and all-sky observations demonstrates that the patches must have been segmented equatorward of the cusp/cleft...
متن کاملRadio sources at low Galactic latitudes
High-resolution radio observations of a sample of 65 radio sources at low Galactic latitudes are presented. The sources were all observed at 5 GHz with the VLA A-array. MERLIN observations at 5 GHz of the ultracompact H ii region G34.26+0.15 and one of the extragalactic sources, B1857−000, are also presented, as are GMRT observations of H i in the direction of three sources, B1801−203, B1802−19...
متن کاملCloud Phase Determination Using Ground-Based AERI Observations at SHEBA
A new technique for ascertaining the thermodynamic cloud phase from high-spectral-resolution ground-based infrared measurements made by the Atmospheric Emitted Radiance Interferometer (AERI) is presented. This technique takes advantage of the differences in the index of refraction of ice and water between 11 and 19 mm. The differences in the refractive indices translate into differences in clou...
متن کاملStructure of the Sagittarius dwarf galaxy at low Galactic latitudes
We report the detection of ∼1 500 RR Lyrae of Bailey type ab located in the Sagittarius dwarf galaxy (Sgr). These variables have been detected on two ESO Schmidt fields centred on (l,b)=(3.1,-7.1) and (6.6,10.8), covering an area of ∼50 deg. We present a surface density map of Sgr based on the spatial distribution of these RRab, allowing us to trace its structure in a region that was still almo...
