NGC5033 a large Seyfert galaxy (John Favalessa)

NGC5033 a large Seyfert galaxy

After all the cloudy nights in February, March, April, May and June, I woke up to the fact that I mostly missed galaxy season 😩! I had hopes of going deep on many galaxies and clusters this year. Only got a few nights of a few galaxies and one cluster…oh, well there’s always next year.

One that I did get was NGC5033. I’m surprised that is not often imaged here on astrobin, but I found it an interesting target from my backyard in April. At 60MLYs it’s in the wheelhouse for my 9.25HD. Certainly, an interesting galaxy. It’s huge, like twice the size of our Milky Way. We are not looking face on. So the spiral arm at the top seems to extend above the plane. And then there’s a blob at 1 o’clock. It's pretty cool at full resolution...I might do a mouse over. Some research revealed that this is one of the nearest large Seyfert galaxies. Lots of eye candy in the frame also...what the hey is PGC45927?

From Wikipedia: any of a class of galaxies known to have active nuclei. Such galaxies were named for the American astronomer Carl K. Seyfert, who first called attention to them in 1944. They have quasar-like nuclei (very luminous sources of electromagnetic radiation that are outside of our own galaxy) with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, their host galaxies are clearly detectable. Seyfert galaxies account for about 10% of all galaxies and are some of the most intensely studied objects in astronomy, as they are thought to be powered by the same phenomena that occur in quasars, although they are closer and less luminous than quasars. These galaxies have supermassive black holes at their centers which are surrounded by accretion discs of in-falling material.

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.
