Zooniverse projects: Black Hole Hunters, SuperWASP Variable Stars
What is your research about?
I search archives of astronomical observations, looking for patterns which might be caused by interesting types of star or rare astronomical events. I work with so-called “time series” data, which is where measurements are taken repeatedly over time. In my case, I’m looking at how the brightness of stars changes over anything from days to years. In SuperWASP Variable Stars, we’re looking for certain kinds of repeating variability, such as eclipses and pulsations, in data originally collected by the SuperWASP exoplanet search. In Black Hole Hunters, we’re looking for a type of gravitational microlensing, where a black hole briefly magnifies the light from a star, and we’re currently searching the archives of the TESS exoplanet search, with plans to add data from several other surveys in the near future.
How do Zooniverse volunteers contribute to your research?
The volunteers make our projects possible. We’re looking for the things that get missed by automated searches. Computer algorithms are great at finding a lot of things, but no matter how good they are there will always be things that they miss. Slightly odd looking examples, noisy data, and unexpected things that no one knew to program the computer to find. Only people can find these things, and there is simply too much data to look through ourselves.
In SuperWASP Variable Stars, we’re looking for stars that have been missed in previous searches of the data. The SuperWASP data can be particularly noisy, which can make searching it a challenge. We’ve found that people are really good at separating the noise from the real thing. We’ve written up and published some of the results of this project already, and we publish an interactive database of the results at superwasp.org.
In Black Hole Hunters, the microlensing events we’re looking for are expected to be the hardest ones to spot. Even with really high quality data, we expect the most interesting events to barely stand out against the background noise. That’s what makes a manual search so useful.
What’s a surprising or fun fact about your research field?
The Milky Way is predicted to contain millions of black holes, but we only know about roughly 70 of them. Those were almost all spotted because they’re not really black, at least in X-rays. They’re very bright in X-rays because they’re consuming matter, which heats up as it falls into the black hole. The vast majority of black holes are not expected to be feeding and should truly be black. Those are the ones we’re looking for! We can’t see the black holes themselves, but we should be able to see the effects of their gravity. That’s why we think gravitational microlensing is a good way to find them.
What first got you interested in research?
I have always been interested in science and astronomy for as long as I can remember. I had a telescope as a kid, and I remember going outside to look at the comet Hale-Bopp with my dad. I’m afraid I don’t really remember the first time I thought about actually doing research myself, but I took a rather indirect route to get here. Despite being interested in research (and almost doing a computer science PhD), after university I first worked as a web developer for a few years before eventually finding my way to an astronomy PhD.
Outside of work, what do you enjoy doing?
I’d honestly love just to be able to spend a day sitting and reading a book, but these days my children take up most of my spare time (and energy)! Maybe I’ll be able to do that again in a few years. Also, nothing beats a long walk in the country with the dog.
What are you favourite citizen science projects?
It’s been a long time since it was active, but I always had a soft spot for the SETI Live project here on the Zooniverse. It was obviously unlikely to find anything, but there was something exciting about working on data in real time as it came off of the telescope.
What guidance would you give to other researchers considering creating a citizen research project?
If you’ve never done it before, talk to those of us who have! Especially when it comes to the Zooniverse, everyone is very friendly and happy to help, so there’s no need to try and figure everything out on your own.
