Features & Capabilities

Welcome to the Black Hole Finder, an exciting citizen science project dedicated to discovering black holes, particularly those formed from the fusion of two neutron stars. You have the unique opportunity to contribute to this cutting-edge research from the comfort of your home, using your phone, tablet, or computer.

Our app brings the cosmos to your fingertips. When two neutron stars merge, they create a powerful event, sending gravitational waves through space. These events are detected by our gravitational wave detectors, which alert us to potential black hole formations. Mergers of this kind not only create black holes but also give birth to rare Earth elements such as Iodine, Gold, and Cerium. All these elements, especially Iodine, play crucial roles in supporting life as we know it.

In addition to gravitational waves, these cosmic collisions emit light signals. The chase is on to detect these signals with our trio of specially designed BlackGEM telescopes located in Chile. The catch is that the detectors only provide a general localization of the event and the light signals are fleeting. Therefore, we need to act quickly to capture these signals before they fade away after a few days or a week at most.

That's where you come in! Using our app, you will sift through real-time images of the sky taken by our BlackGEM telescopes. You will help us spot these light signals, effectively identifying potential new black holes. Not only will you be possibly among the first to set eyes on the light from these celestial events, but with some training, you may also direct telescopes to take additional measurements of intriguing objects.

Your contributions to science won't go unnoticed. Participants who make significant discoveries will be offered co-authorship on scientific publications that result from their findings. We also provide training and guidance to enrich your understanding of the cosmos.

The Black Hole Finder project is not just about making significant scientific contributions. It's about engaging with the wonders of the universe, learning about the intricate processes that drive its dynamics, and having fun while doing it!

So, join us on this thrilling journey of discovery and exploration. Download the Black Hole Finder app now and start your cosmic adventure!

Weird I know. I like the idea that I’m helping these scientists. Looking at 3 static images over and over also helps my mind not race. I have no idea if I’ll ever get feedback on if I correctly identified a black hole but it’s not a big deal for me. You guys are busy unlocking the secrets of the universe and this app probably isn’t top priority XD Anyway! Thanks for letting me be a part of this

Nemo ... has some excellent points. I just fired the app up this evening and it says there's nothing to analyze right now. Are we still engaged, or is my analyzing so bad that they don't want my help anymore? Anyway, hope there's more work in the future.

This app is a good idea: enlist people to help find kilanova in sky surveys by excluding non-astrophysical light sources. They train you with samples, BUT there is no feedback when you assess transients, and no sense what proportion are likely to be ‘real’. I think when you mark ‘real’, you are just saying, ‘yeah, this is an astrophysical light-source,’ not ‘this is a kilanova.’ That would mean the ratio of real to bogus is much higher. But the app doesn’t make that very clear, so I select unknown quite a bit. What would b great would be a quiz against a vetted set of transients. That way you could guess then see the correct answer. New quizzes every so often between actual assessments would be great. I don’t want to me incorrectly training the algorithm!! Also, does the app need a certain number of ‘real’ selections on a given sample to be added to the real set, or is it just my assessment? Yikes! I love the idea of supporting the effort; it feels meaningful. But a community, message board, quizzes, etc would go a long way in making me feel I am doing more good than harm.
