Science Online: The Good, the Bad and the Crazy

In 2010, astrophysics professor Pavel Kroupa at the University of Bonn – he of the stellar Initial Mass Function - published a paper in which he highlighted problems with the Standard Model of Cosmology (the so-called ΛCDM model, of which cold dark matter is a crucial ingredient), particularly in its predictions related to environments of large spiral galaxies. In a provocative move, he cited the discrepancies between the model’s predictions and observations as evidence that ΛCDM “doesn’t work”, and that we should explore alternative theories. One of these alternatives is Modified Newtonian Dynamics, or MOND.

In the months after the publication, the University of Bonn hosted a debate on this thorny subject between Kroupa and one of the architects of the ΛCDM framework, Simon White, Director of the Max Planck Institute for Astrophysics in Garching. I thought this was an excellent idea, wrote a few blog posts about the matter and posted the live blog and video of the debate.

To those that read or watched the debate, it was clear that the two scientists don’t disagree in a fundamental way - ΛCDM has proved an extremely successful framework for cosmological structure formation, but the dwarf satellite problem is generally acknowledged. Kroupa’s most important point is that the community should not ignore those observables that don’t match the predictions of ΛCDM, and he encourages scientists not to get locked into a “cold dark matter” mindset, but to explore entirely novel theories, of which MOND is one example. This discussion has been expanded and illustrated further in a blog run by Marcel Pawlowski, a member of Kroupa’s group in Bonn, the Dark Matter Crisis, now hosted on SciLogs.com, which is run by Nature and the German edition of Scientific American.

.Astronomy Unproceedings

In the last few .Astronomy conferences we’ve shied away from producing conference proceedings in the classical form – authors hate writing them, organisers hate editing them, and they end up gathering dust on a shelf somewhere. But as we feel the conference is quite unique in its scope, content and format, we wanted to leave some kind of record – for ourselves, for our participants and to inform everyone else what happens at .Astro and why they should take an interest. So in the last few months a group of .Astro organisers and alumnae/i, including myself, put together a legacy document about last summer’s Heidelberg conference. And in .Astro style, we’ve called this the .Astronomy Unproceedings. The document was posted to astro-ph at the end of January, go read it here.

And while I’m on the subject, there’s only about a week left to sign up for .Astronomy 5, which will take place from 16 to 18 September in Cambridge, MA. It’s been very cool to discuss the plans for the next event (without having to worry about all the local planning!). We’re always looking to diversify in every possible way – skills, ideas, background, geography, profession, gender, age etc. So whatever you can bring, please sign up on the form and tell us about it.

Sign up for .Astronomy 5!

Today I signed up for the 5th edition of .Astronomy 5, which will take place in Cambridge, Massachussettes from 16 to 18 September 2013. I can’t believe it’s the 5th edition already – I was just a little baby postdoc of 27 when I travelled to Cardiff for the first edition – and I’m excited to be part of it now.

It’s the first time .Astronomy is crossing the pond to North America, and our local hosts in 2013 will be the Seamless Astronomy group at Harvard’s Center for Astrophysics, in particular Alyssa Goodman and Gus Muench. Several of the group’s members are .Astro alums, and with all the fascinating work they do, the links they have with the VO community and ADS, there’s no one better to organise the first US-based .Astro. The conference venue is Microsoft’s New England Research & Development Center (MS NERD) – a perfect hub for a few days of hacking and unconferencing.

The sign up form is here, so if you’d like to come along, tell us here why and what you hope to contribute. As always we’ll be limiting participant numbers to around 50, so do tell us why the conference needs you!

As an aside, it’s super to see that two “.Astro-style” hack days have taken place in the US in recent months: there was one in New York, and this week a 2nd at the AAS conference in Long Beach. I’ve been very jealous to read all the excited tweets flying around, and I wish I’d been able to join! Whenever I talk about .Astronomy in the community, I always encourage people to organise their own events – a hack days requires very little organisation or money and is a good way of finding your local kindred hacky spirits, networking, generating new ideas or finding solutions for problems you’ve been working on. Excellent to see that happening!

Peer review, Open Access and the Arxiv

In recent months it’s started to look like the UK is getting serious about open access: several high profile scientists and members of the government have spoken out in support of making publicly funded research openly available. Yesterday Science Minister David Willetts announced plans to enforce open access in the UK by 2014 in an interview with The Guardian:

Under the scheme, research papers that describe work paid for by the British taxpayer will be free online for universities, companies and individuals to use for any purpose, wherever they are in the world.

It’s everything we ever wanted! Or is it?

The catch lies in the implementation of such a scheme. Publishing still costs some money, and several models are commonly discussed in the context of open access. The proposed plans in the UK seem to envisage a “gold model”, where the publication costs are transferred to the science community, who could face charges of ~£2000 for the publication of a paper, which will then be freely available to anyone and everyone. No additional funds will be made available in grants to pay for such charges, so scientists face an additional financial burden just to get their work published.

A few thousand here and there may seem like a drop in an ocean where billions are spent on research every year. But at the level of individual groups this is a non-trivial amount of money. Here at MPIA we were informed of a budget shortfall this year, and asked to consider publishing in cheaper journals like MNRAS to keep costs down. Incidentally, as long as the expensive journal has a higher impact factor and is more visible in the US community, and search committees are told to care about such things, I will continue to submit to the expensive journals. Senior professors can take a stand and refuse to pay publication charges, but at the PhD and postdoc level we just can’t afford that luxury. And if you happen to work at Queen Mary in London you may be screwed on that front even if you have a permanent position.

I think it’s great that this debate has become so high profile, and that people at a high level are aware of the benefits of public access to research. But there’s some grumbling about the extra costs involved, and the sanity of introducing such measures unilaterally in one country. Some complain that freeing up UK research only will give a competitive advantage to the rest of the world.

In astronomy > 90% of all literature ends up on the Arxiv so in a sense we have dealt with our open access problem already. I had an interesting twitter exchange with Peter Coles, Mike Merrifield, Andy Lawrence and Matt Burleigh (his blog post on the subject here) after the news from the UK was announced, about ways to incorporate the stamp of approval lent by peer review into the Arxiv system (I see Peter has written about it too). I grumbled, and they came up with an idea.

[If only they'd been at .Astronomy! We could have had the whole service set up already for a trial.]

Papers submitted to Arxiv could be voluntarily submitted for peer review, which is provided by some kind of independent service where reviewers are paid a small amount of money for their effort. As the case is now, the referee can vote to reject the paper. If it’s accepted, the Arxiv submission could gain some sort of mark of endorsement on the webpage to inform readers of the quality of the research. In parallel, authors could still post their conference proceedings or other non-refereed writings to the Arxiv as they do now. As Peter writes, such a system requires some organisation and funding but there are no fundamental barriers (besides influence from the journals of course) to the implementation.

Who will take the lead?

 

 

.Astronomy 4: TimTam Slams, Visual Goodness, and an Awful Lot of Code

Science: It’s Universal from amanda bauer on Vimeo.

Well, .Astronomy, after all those months of preparation, you sure went by quickly. On Monday, Tuesday and Wednesday this week, our 50-odd participants made for yet another super conference. It was just as much fun and just as exciting as previous years, but also very different. It’s interesting how the setting and venue of a conference really affects the vibe, and I think this was a particular plus in Heidelberg. Star of the show was the Haus der Astronomie, where we spent our daytime sessions – our local brand new galaxy-shaped building housing a full fledged planetarium, good wifi, and great spaces for unconferences and hacking.

For me what stood out further was the technical competence of the participants. The outcomes of the hack day were truly amazing, considering it only lasts one day. I wish I had this brilliant mixture of ideas and technical skills around me on a daily basis. I’m pleased about my recent progress in Python, but I’m still a coding zygote compared with most of the .Astro community.

A big theme this year was visualisation, and we’d invited two visualisation professionals to give a keynote talk: Julie Steele of O’Reilly Media, and Noah Iliinsky, visualisation consultant and author. Their talk was fab, and their presence meant that everyone ws giving a lot of thought to interfaces and visual appearance of their hacks.

Several participants have written about the conference and the hacks so I will just point to their sites:

Amanda Bauer (astropixie) – here. She also made the above video with Nicole Gugliucci, which is a top effort (and extra points for working through the night to get it done!)

Stuart Lowe (astronomyblog) – a great summary of the conference.

David Hogg – updates on his research blog for day one, two, three.

Fellow organisers Rob and Chris did an episode of their regular podcast Recycled Electrons (mp3) from the conference.

I’ll add links or more comments as they appear…..

Finally, thanks to all our participants for coming along and making it a fab conference. I look forward to seeing some of you at .Astronomy 5!
