Cause of Late 2013 Imac Kernel Panic

Question

I have just got home from work to find my imac in a cycle of kernel panics. I have tried entering safe mode by holding the shift key when booting up with no luck (I'm using the apple wireless keyboard and there is no startup chime so I am waiting for a second or two).I would be grateful if anyone could diagnose the problem from this log and give me any adive to get back up and running:

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.
