  2. Polarimetry - Wikipedia

    en.wikipedia.org/wiki/Polarimetry

    Polarimetry is used in remote sensing applications, such as planetary science, astronomy, and weather radar. Polarimetry can also be included in computational analysis of waves. For example, radars often consider wave polarization in post-processing to improve the characterization of the targets.

  3. Polarization (cosmology) - Wikipedia

    en.wikipedia.org/wiki/Polarization_(cosmology)

    The launch of the IXPE telescope in late 2021 made polarization measurements in the 2–8 KeV band also a reality (more than 40 years after the pioneering observations of the OSO-8 satellite) and its polarimetric observations confirmed theoretical predictions, according to which X-ray radiation from magnetar sources is also highly polarized, up ...

    1962 — A.S. Bennett of the Cambridge Radio Astronomy Group publishes the Revised 3C Catalogue of 328 radio sources; 1965 — Gerry Neugebauer and Robert Leighton begin a 2.2 micrometre sky survey with a 1.6-meter telescope on Mount Wilson; 1982 — IRAS space observatory completes an all-sky mid-infrared survey

    en.wikipedia.org/wiki/XPoSat

    POLIX is the primary scientific payload aboard XPoSat. It is a Thomson X-ray polarimeter, which measures the degree and angle of polarization (polarimetry parameters) of astronomical sources in the medium X-ray range (8-30 keV). [27] It has been developed by Raman Research Institute. Its science objectives are to measure: [26]

New 6 in Indus (chart 23 in Tirion's Sky-Atlas 2000.0, chart 413 in the 1987 edition of Uranometria 2000.0, Volume 2) (as ESO 287-G13) NGC — New General Catalogue

  8. IXPE - Wikipedia

    en.wikipedia.org/wiki/IXPE

    IXPE's payload is a set of three identical imaging X-ray polarimetry systems mounted on a common optical bench and co-aligned with the pointing axis of the spacecraft. [1] Each system operates independently for redundancy and comprises a mirror module assembly that focuses X-rays onto a polarization-sensitive imaging detector developed in Italy ...

  9. Celestial cartography - Wikipedia

    en.wikipedia.org/wiki/Celestial_cartography

    Celestial cartography, [1] uranography, [2] [3] astrography or star cartography [citation needed] is the aspect of astronomy and branch of cartography concerned with mapping stars, galaxies, and other astronomical objects on the celestial sphere. Measuring the position and light of charted objects requires a variety of instruments and techniques.
