... Observations of edge-on galaxies[ 3 , 10 , 19 ] have demonstrated that some have extended hot halos; while observations of face-on spiralgalaxies[ 5 ] provide upper limits to emission from their halos. ...
... But observations of nearby fac e-on spiralgalaxies show that dozens of molecular clouds with 105 - 106 M producing clusters with 104 stars must be present in our Galaxy. ...
... Its companion, located at 2.5 to the northwest, is the spiralgalaxy NGC 4647. NGC 4649 harbors a faint nuclear radio source (Condon et al. 2002). ...

... The matching experiment here only informs us that the progenitor spiralgalaxies are required to be sufficiently large (i.e., scale length of the stellar disk Rdisk 4 kpc), to produce the length of the tidal tails, and that they must have contained pre ...
... The brightest nearby spiralgalaxies observed by Fabbiano & Trinchieri (1985) show log L \ 23.5, and elliptical galaxies achieve log L \ 24, 2 keV is near to which keV the apparent X-ray luminosity2 of our 2 detected loBAL QSOs. ...
