Greetings Voorwerpje Hunters,

First off, I second Dr. Keel in saying, THANKS! This project has already been the thrill of a lifetime already and I can hardly believe it's just getting started.

Whereas the voorwerpje journal paper will focus on the 19 confirmed voorwerpje hosts, I have created a webpage showing ALL of the results from last summer's voorwerpje survey. The page includes spectra from the ~30 or so galaxies targeted as potential voorwerpje hosts, spectra from targets suggested by GZ forum regulars while we were actually at the telescope, and finally, a handful of spectra from objects we looked at just for fun (like Neptune). If you're curious about how the confirmed voorwerpjes were actually confirmed, or if you just enjoy looking at AGN spectra, the page is here - http://wwwstu.tcu.edu/drewchojnowski/AGNspectra1.html.

Maybe. Interpreting the Hubble images for clouds like this is complicated by the facts that there may be fewer filters used than for the Sloan survey (so we have less precise ability to distinguish between things that are blue because of young stars and emission lines) and that the Hubble data span large redshift ranges, so that there are multiple ways an emission line can land in a given filter.

That said, this is an interesting candidate that goes into the list when we get the Hubble candidates properly sorted out! The two arcs do look like what we see some of the confirmed nearby objects.

The Voorwerpje paper has now been accept by MNRAS, links will be provided as soon as it is public on arXiv.   ;D

The first Hubble observing is next week.   ;D

More news - just learned that a proposal led by Megan Argo has been awarded time on the Westerbork Synthesis Radio Telescope (WSRT, in the Netherlands) to look for H I tidal features around Voorwerpje host galaxies in the 21-cm emission line. This is the same instrument used by Josza, Garrett and collaborators to find the enormous hydrogen streamer of which Hanny's Voorwerp is a part.

(Small world - the head of the WSRT program commission was my project advisor as a summer student doing radio astronomy back when the VLA was only a Pretty Big Array).
