Galaxy Zoo paper on host galaxies of growing black holes submitted!
It’s usually me who is reminding people to go blog about paper submissions and acceptances, so it’s a bit embarassing that I forgot to remind myself last week to announce the submission of the latest Galaxy Zoo paper.
I’ve been working on it for a while, probably over a year. The paper took so long to finish because not only did we have to analyse a huge amount of data, it also took quite a while to figure out what it all meant. I kept producing new plots that showed trends that didn’t really make any sense to us. We therefore needed to take our time digesting what we saw and condensing it into a `readable’ paper. It still over 20 pages long and there are still many results for which we could only offer some speculation. It’s not an easy paper to summarise, so I will (for now) simply summarise it as: “the black hole growth in spiral and elliptical galaxies is due to completely different evolutionary scenarios.”
Or, as I will put it in my talk on Friday at the IAU Symposium on the black hole-galaxy connection:
The answer may depend on
