NGC 5754 – galaxy with high redshift arm

NGC 5754 has a close companion (NGC 5752, object 3 in Figure 3) and also NGC 5755 (object 6) is nearby (but apparently twice as far in the background). The system has been included to several studies of interacting galaxies but to my knowledge it has not been discussed as discordant redshift system before. This [...]

NGC 3299 – background galaxy shining through disk?

There is a high redshift galaxy (object 2 in Figure 1) within the disk of NGC 3299. Only two other objects have measùred redshifts within 5 arcmin from NGC 3299. There is a measurement of a HII region or similar in NGC 3299 disk (object 3) and further out there’s a high redshift galaxy (object [...]

IC 1767 – QSO pair alignment

In 1968 Arp reported a finding of two radio sources aligned across IC 1767 (Arp, 1980). Arp (1980) writes: The pair of radio sources had been identified, first because of its closeness and orientation, as most likely belonging to the galaxy IC 1767. On further inspection it turned out that the apparent flux and spectral [...]

NGC 1136 – Higher redshift companion

NGC 1136 was included to the sample of Arp (1981). Arp described the system as disturbed spiral with disturbed companion. He wrote: The central spiral has strong, disturbed arms. The companion is relatively bright and strongly distorted. The spectral characteristics of the companion are younger. This is a prototype example of a spiral with an [...]

NGC 5107 – QSO at minor axis

NGC 5107 is a companion galaxy to NGC 5112. Arp (1981) included this system to his set of new quasars near companion galaxies. He wrote: Figure 15 (Plate 11) shows that very close to this companion a new quasar has been discovered. (The quasar in question is object 2 in Figure 1 below.) Burbidge et [...]

NGC 7603 – the discordant redshift system

NGC 7603 (object 1 in Figure 1) system was included in Halton Arp’s Atlas of peculiar galaxies. Subsequently Arp (1971) noticed that the companion of NGC 7603, NGC 7603B (object 4 in figure 1), had much higher redshift than NGC 7603 and was connected to NGC 7603 by an anomalous arm. Unfortunately, not even the [...]

Abell 85 – galaxy sheets or quantized redshifts?

Beers et al. (1991) measured some new redshifts for Abell 85 (among few other clusters). They first noted that the velocity spread for the Abell 85 is very large. Then they noted that there are five galaxies at lower redshift so that there is a clear gap between regular Abell 85 radial velocity distribution and [...]

UGC 05015 – QSO-galaxy pair

Arp (1980) discussed the companion galaxies of NGC 2859. One of the four discussed companions is UGC 05015 (object 1 in Figure 1). Specifically, Arp studied quasars near companion galaxies. He noted that UGC 05015 had an ultraviolet excess object in its vicinity. Arp studied it spectroscopically, and it turned out to be a quasar [...]

3C 345 – the quasar line

Most of the field around 3C 345 will be handled with NGC 6212, which is close to 3C 345, so here I will only deal with the discordant redshift issues that has been discussed in the scientific literature with 3C 345 as the central object. In addition 3C 345 has been a subject for a [...]

3C 303 – a nearby QSO with possible radio bridge

Kronberg (1976) studied the radio structure of 3C 303 field. Kronberg noted: Also visible is a low brightness extension of the western component toward the southwest. This extension is approximately superposed on a ~19.5 mag object at ([alpha] = 14h41m22s68, [sigma] = 52[degrees]14’18″0) which is clearly visible in Figure 1 and which we shall call [...]
