This all-sky image shows the spatial distribution over the whole sky of the galactic haze at 30 and 44 GHz, extracted from the Planck observations. In addition to this component, other foreground components such as charged particles accelerated radially, known as synchrotron radiation, thermal dust, spinning dust, and extragalactic point sources contribute to the total emission detected by Planck at these frequencies. ...

... We show the analysis of low-hard and intermediate states of sources XTE J1550-564, H 1743-322, GX 339-4, XTE J1859-226, XTE J1650-500 and GRS 1915+105. ... Directly applying the scaling technique we also obtain that a ratio of the BH masses in XTE J1859-226 and in XTE J1550-564 is , and the corresponding ratio for XTE J1650-500 and XTE J1550-564 is . These values of scaling factors r implies that BH masses are ; solar masses in XTE J1859-226 and XTE J1650-500 respectively. ...

We present spectral line images of [CI] 809 GHz, CO J=1-0 110 115 GHz and HI 1.4 GHz line emission along a ~1ТА region in the l=328ТА direction of the Galactic plane. The [CI] data comes from the High Elevation Antarctic Terahertz (HEAT) telescope, a new facility on the summit of the Antarctic plateau where the precipitable water vapour falls to the lowest values found on the surface of the Earth. ... The [C/CO] abundance ratio averaged through the filament is found to be approximately unity. ...

These are very prominent absorption lines is most all galaxies. ... These pair of absorption lines will appear in all the spectra and they should be your principle source for determining the redshift. ...

Note: What you are doing in this excercise is identical to what Hubble did in the 1920's and you are using the same galaxies. ...

... The VSOP Survey Continuum Source List . The radio sample for the VSOP continuum survey was defined to include all extragalactic radio sources with: . a total flux density at 5 GHz, S>=1.0 Jy . ... The sample also included all sources in the sky with a 5 GHz flux density S>5 Jy, regardless of spectral index and galactic latitude. ... The source would then be included in the VSOP sample (three of the sources were found with a flux density above 1 Jy and added to the sample). ...
