NGC 7525 (= PGC 70731)
Discovered (Nov 3, 1864) by
Albert Marth (538)
Two spiral galaxies in Pegasus
NGC 7525 NED02 = A 14th-magnitude spiral galaxy (type S??) at RA 23 13 40.4, Dec +14 01 17
NGC 7525 NED01 = A 15th-magnitude spiral galaxy (type S??) at RA 23 13 40.2, Dec +14 01 27
Historical Identification:
Physical Information: The galaxies that comprise NGC 7525 have about the same recessional velocity (as discussed below), and are therefore at nearly the same distance. However, there is no obvious tidal distortion in the image below, so they may not be as close as they appear (although even if they are separated by several million light years, that would be nothing in comparison to their half billion light year distance from us). Face-on NED02 obviously lies in front of edge-on NED01, but their separation is unknown and probably unknowable, given the caveats listed above. Their recessional velocities (11945 km/sec for NED01 and 12260 km/sec for NED02), if used in a straightforward calculation, would indicate a distance of about 555 to 570 million light years. However, for objects at that distance, it is necessary to take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the two galaxies were about 545 million light years away when the light by which we see them was emitted, about 555 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and their apparent sizes (about 0.35 by 0.35 arcmin for face-on NED02, and 0.45 by 0.1 arcmin for edge-on NED01), NED01 is about 70 thousand light years across, and NED02 about 60 thousand light years in size. Since NED01 is nearly edge-on, it is difficult to say much about its detailed structure; but face-on NED02 is a starburst galaxy, and also a Seyfert galaxy (type Sy 1.5).

NGC 7547 (= PGC 70819) (not part of
Arp 99)
Discovered (Aug 26, 1827) by John Herschel
A 14th-magnitude spiral galaxy (type (R')SAB0(s)a? pec) in Pegasus (RA 23 15 03.4, Dec +18 58 25)
Historical Identification:
Physical Information: Apparent size about 1.1 by 0.5? arcmin. Some catalogs include this galaxy in Arp 99, which is listed in the Arp Atlas as an example of a spiral galaxy with an elliptical companion; however, the remarks in Arp's catalog make it clear that the spiral galaxy in question is NGC 7549, and though NGC 7547 is mentioned in passing (as the "West galaxy"), it is clearly not the galaxy that is meant to be part of Arp 99. Arguments that NGC 7547 should still be considered part of Arp 99 ignore the fact that if it were, the entry would have been listed as an elliptical galaxy with spiral companions; and since it was not, NGC 7547 is clearly not part of Arp 99. However, it probably is part of a triple system with the galaxies comprising Arp 99, as all three have similar radial velocities.

NGC 7549 (= PGC 70832, and with

Discovered (Nov 2, 1850) by Bindon Stoney
A 13th-magnitude spiral galaxy (type SB(s)cd? pec) in Pegasus (RA 23 15 17.1, Dec +19 02 29)
Historical Identification:
Physical Information: Apparent size about 2.8 by 0.7? arcmin. Used by the Arp Atlas as an example of a spiral galaxy with an elliptical companion (NGC 7550). Some catalogs incorrectly include NGC 7547 as part of Arp 99, so see that entry for a discussion of why that is wrong. However, NGC 7547 probably is part of a triple system with the pair of galaxies that form Arp 99, as all three have similar radial velocities.
