Centaurus A with Inner Jet (NGC5128)

"A mere 11 million light-years away, Centaurus A is the closest active galaxy to planet Earth. Spanning over 60,000 light-years, the peculiar elliptical galaxy, also known as NGC 5128, is apparently the result of a collision of two otherwise normal galaxies resulting in a fantastic jumble of star clusters and imposing dark dust lanes. Near the galaxy's center, leftover cosmic debris is steadily being consumed by a central black hole with a billion times the mass of the Sun. As in other active galaxies, that process likely generates the enormous radio, X-ray, and gamma-ray energy radiated by Centaurus A. " [Extracted from NASA APOD March 2022]

The total of 23.2 hrs of LRGBHa data in this image were collected by DeepSKyWest at Rio Hurtado, Chile between 30 Dec 2022 and 21 Feb 2023.

The tight framing of this image was intended to focus on the very complex structure of this "Cen A" target, but I was surprised to see in the upper left edge of the image the fairly strong Ha emission signal measured from a hydrogen jet (inner filament "Jet A" in the literature) that is emitted from its massive central black hole. There are also outer jet filaments (Jets B and C) that are larger in extent and at a greater distance in roughly the same direction but out of the frame of this image. However, reprocessing the larger-frame raw data for the Ha channel that should have contained at least the outer Jet B, there was no significant Ha signal. (Virtually all of the Jet A signal here was in the Ha channel).

Version C: (now "Original"): Backed off on BxT almost entirely to better control the AI.Slight vertical crop to emphasize the jet more.

Version D: Removed the slight vertical crop for better balance.

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.
