I’m delighted to announce that the fifth Galaxy Zoo paper – the one that discusses Hanny’s Voorwerp – has now been accepted for publication by Monthly Notices of the Royal Astronomical Society.
It’s somewhat of a relief to say that, as it was way back in August of last year that we first submitted it. The referee was extremely thorough, catching a few stupid mistakes we’d made (as a good referee should) and in correcting these and responding to responses for clarification the paper grew from four pages to thirteen. The basic story is still the one that Bill and I outlined more than a year ago – we think we’re seeing the result of activity associated with the black hole in the nearby galaxy IC2497 which has now ceased.
Along the way, another team of astronomers have published a paper about their radio observations of the Voorwerp; I’ll blog later in the week about how we think the two sets of observations are compatible. Hopefully they’ll do the same, and we can have a discussion in public about what we do – and don’t – agree on. By coincidence, their paper is being published in the journal Astronomy & Astrophysics this week – and their image of the Voorwerp made the front cover of the printed edition. We’ll have an image of that for you as soon as anyone involved can find a printed edition – a rare thing in this internet age.
Update : Paper is now available here.
P.S. For those keeping score, our Voorwerp paper was the 5th to be submitted, but the 6th to be accepted.
Update: The pre-print is available on astro-ph now.
