Since then, some additional works have cast doubt on the "supervoid" explanation. The correlation between the NVSS dip and the Cold Spot was found to be marginal using a more conservative statistical analysis. [13] Also, a direct survey for galaxies in several one-degree-square fields within the Cold Spot found no evidence for a supervoid. [14]
Southern Eridanus Void: The Southern Eridanus void is connected to the Eridanus void by a hole in the distribution of galaxies separating the two. A hole in the distribution of galaxies separating Sculptor and Southern Eridanus voids the size of (redshift) 1250 km/s appears to exist. [11] Fornax Void: Hercules Void: 15.5 h +30° cz=7000 km/s ...
Eridanus Supervoid: 489,000,000 (most likely value) A recent analysis of the Wilkinson Microwave Anisotropy Probe (WMAP) in 2007 has found an irregularity of the temperature fluctuation of the cosmic microwave background within the vicinity of the constellation Eridanus with analysis found to be 70 microkelvins cooler than the average CMB ...
Eridanus is a constellation which stretches along the southern celestial hemisphere. It is represented as a river . One of the 48 constellations listed by the 2nd century AD astronomer Ptolemy , it remains one of the 88 modern constellations .
The Eridanus Group, sometimes called the Eridanus Cloud, is a nearby loose grouping of galaxies at a mean distance of approximately 75 Mly (23 ± 2 Mpc) in the constellation Eridanus. [1] Redshift values show that there are approximately 200 galaxies associated with the group, approximately 70% of which are spiral and irregular type galaxies ...
NGC 1309 is a spiral galaxy located approximately 120 million light-years away, appearing in the constellation Eridanus. It was discovered by German-British astronomer William Herschel on 3 October 1785. [3] NGC 1309 is about 75,000 light-years across, and is about 3/4s the width of the Milky Way.
S. Knapton, Mysterious 'supervoid' in space is largest object ever discovered, scientists claim, The Telegraph; Can someone confirm that the void in the list is the void the article talks about? Also, am I understanding this correctly that this is different from the suspected "Eridanus supervoid"?
58 Eridani is a main-sequence star in the constellation Eridanus. It is a solar analogue, [12] having similar physical properties to the Sun. The star has a relatively high proper motion across the sky, and it is located 43 light years distant. It is a probable member of the IC 2391 moving group of stars that share a common motion through space ...
