The North Ecliptic Pole Wide survey of AKARI: a near- and mid-infrared source catalog⋆
We present a photometric catalog of infrared (IR) sources based on the North Ecliptic Pole Wide field (NEP-Wide) survey of AKARI, which is an infrared space telescope launched by Japan. The NEP-Wide survey covered 5.4 deg2 area, a nearly circular shape centered on the NEP, using nine photometric filter-bands from 2−25 μm of the Infrared Camera (IRC). Extensive efforts were made to reduce possib...
متن کاملInfrared broadband 50%-50% beam splitters for s-polarized light.
Prisms and slabs made of high-refractive-index materials such as ZnSe, Ge, and Si can be designed as broadband, 50%-50%, beam splitters (BSs) for obliquely incident s- polarized light in the near- and mid-IR. The beam-splitting face of the prism or slab is uncoated, while the exit face is antireflection coated. The split beams travel in orthogonal directions when light is incident at the Brewst...
متن کامل50 Tev Hegra Sources and Infrared Radiation
The recent observations of 50 TeV gamma radiation by HEGRA have the potential of determining the extragalactic flux of infrared radiation. The fact that radiation is observed in the range between 30 and 100 TeV sets an upper limit on the infrared flux, while a cutoff at Eγ ≈ 50 TeV fixes this flux with a good accuracy. If the intrinsic radiation is produced due to interaction of high energy pro...
متن کاملNorth - Holland The injector microtron for the TEUFEL infrared laser
Progress is reported on a 25 MeV injector racetrack microtron for a 10 wm radiation free electron laser (TEUFEL project). The accelerator exhibits transverse focusing in 180° inhomogeneous two-sector dipole magnets which are slightly rotated with respect to each other in the bending plane . This provides closed orbits, isochronism and a large transverse acceptance. Details on this unconventiona...
متن کاملThe Far-infrared Luminosity Function from Goods-north: Constraining the Evolution of Infrared Galaxies
We present the IR luminosity function derived from ultradeep 70 mm imaging of the GOODS-North field. The 70 mm observations are longward of the PAH and silicate features which complicate work in the MIR. We derive far-infrared luminosities for the 143 sources with mJy (S/N 1 3 j). The majority (81%) of S 1 2 70 the sources have spectroscopic redshifts, and photometric redshifts are calculated f...
