The Boötes void is not alone. Other cosmic voids can be found all over space. However, the Local Void is the closest one to Earth. It’s a mere baby in comparison to The Boötes void at roughly 60 million light-years across and forms part of the Virgo Supercluster of which the Mi...
As part of an investigation into the nature of galaxies in voids, 27 galaxies in the Bootes Void were observed in B, V, R & I filters. Absolute V magnitudes have been calculated for most of the galaxies in the sample to an accuracy of 卤0.15 mag or better using apertures that ...
Radial velocities have been measured for 231 galaxies chosen by apparent magnitude from 282 small fields spanning the area on the sky thought to contain the Bootes void. The galaxy distribution exhibits a spherical volume 6000 km/s in diameter in which no objects are found. The rms velocity dif...
or groups of galaxy clusters, that each contain 10 clusters and span up to 200 million light-years. At the heart of Ho'oleilana lies the Bootes supercluster and the Bootes void, which is
Ganymede ocean; or on a planet orbiting a star in the Arches cluster, or one wandering between galaxies in the Virgo cluster; or somewhere in an ordinary galaxy at the heart of the Shapley supercluser, or a rogue planet at the edge of (or near the centre of) the Bootes void; or .....
The legal basis of forced retirement was declared null and void, but this did not directly affect the individual resolutions of the President of Hungary, which actually dismissed the judges. What is more, the President of the National Judicial Office did not initiate a procedure to reinstate ...
Spectrophotometry in the 3400-7700 Å range of ten emission line galaxies in the Bootes void and of five H II galaxies in the direction of the void is presented. Of the ten galaxies in the void, one is a liner, another one is a Seyfert 1, and the other eight are H II galaxies. ...
VLA 20 cm continuum observations of eight emission-line galaxies in the Bootes void are presented. Five of the eight galaxies have weak (0.7 - 4.4 mJy) and compact radio emission. The radio and optical properties of these galaxies are compared with those of Seyferts and starburst galaxies in...
This is often seen to be true from rich cluster sources to the Bootes void emission-line objects. External stimulation is not always required. However, there is a prominent subset of galaxies where interaction with companions has helped to generate a radio source. Such interaction appears to ...
Seven of the galaxies are found near the boundaries of the large Bootes void, and two lie within the void boundaries drawn by Kirshner and colleagues in 1983. The question of whether the void could be populated with low-luminosity galaxies remains unanswered. 展开 ...
