Title: A quasar near a companion galaxy, NGC 5296

Authors: Arp, H.

Journal: Astrophysical Journal, vol. 210, Dec. 1, 1976, pt. 2, p. L59-L61.

An inspection of National Geographic-Palomar Sky Atlas prints revealed a spiral galaxy NGC 5297 and a smaller companion galaxy NGC 5296. A quasar of redshift 0.963 was spectroscopically determined to be in the vicinity of the companion galaxy. In addition, deep photographic plates of the system obtained later revealed a luminous extension from the companion pointing to the quasar. A compact, disturbed galaxy of redshift 25,900 km/s (that of the other two galaxies is about 2500 km/s) was found to be interacting with NGC 5296.

The above is the abstract from Halton Arp's 1976 paper on the quasar he found near NGC 5297. He also discovered the luminous bridge between NGC 5297 and the quasar. He used the world's largest telescope at the time - the Palomar 200" Reflector. I thought it would be an interesting excercise to see if a 10" reflector and a modern ccd camera could image the quasar and bridge.

Details of the objects in the image as follows:

Object Name Apparent Diameter Magnitude Redshift Dist. from Preceding Object

Main Galaxy NGC 5297 308" 12.5 0.0083

Companion NGC 5296 38" 15.0 0.008 88" from NGC 5297

Compact Pec. cgs G1 9" 18.5 0.0863 29" from NGC 5296

Quasar SBO1 stellar 19.3 0.963 55" from NGC 5296. I'm pretty sure I can see the bridge of material linking the galaxy to the quasar. What do you think?? Sorry about the table - couldn't work out how to format it.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
