Next: Extragalactic Gravitational Wave Background Previous: Transparency of the Stochastic . Let the sky be observed with a detector having a pencil beam diagram across. The number of stars per frequency decade that is swept by the detector is a function of celestial coordinates (say, galactic coordinates l , b ): . ... It is clear from the figure that for an all-sky detector the Galaxy becomes transparent above the frequency  Hz. ...

... Dr. Rodrigues, M1 group, Spain, has pointed out the confusion in identification of SN 1998ar in NGC 2916. ... I have measured the locations of point-like sources around NGC 2916 with DSS-1 image and 5 GSC stars. ... The magnitude of this star is estimated as 15.5 mag or so on DSS1 image. ... Star C seems to be dimmer than Star B, and comparing GSC 14.8 mag star and fainter neighbouring stars, its magnitude is about 1.5 mag dimmer than GSC 14.8 mag star; which tells that SN was about 16.3 mag. ...

... As a result of the BTA spectroscopy of a faint optical source (R=23), earlier identified at the BTA with a compact ( RC J0311+0507 from the sample of objects with ultra-steep radio spectra (RATAN-600), a radio galaxy with a strong narrow emission line, the most likely identification of which is the Lyman-alpha hydrogen at redshift of z=4.514. This is the second radio galaxy, discovered at a redshift of more than 4.5 - a real candidate for the most powerful radio objects of the Early Universe. ...
