Space Warps - ESA Euclid

Space Warps and Science Team

Aprajita Verma @aprajita
Aprajita is an astronomer at the University of Oxford, and previously worked at Imperial College London and the Max Planck Institute for Extraterrestrial Physics (Germany). She became fascinated by gravitational lenses during her PhD in which she studied some of the most luminous galaxies seen in the Universe recently discovered in far-infrared surveys, some of which have been gravitationally lensed. Aprajita is interested in making use of gravitational lenses as natural telescopes to study the galaxies that are being lensed in more detail than would normally be possible, as well as measuring the light and dark matter in the lensing galaxies themselves. Having worked with citizen scientists looking for gravitational lenses in Galaxy Zoo, she was inspired by their efforts, motivating the emergence of Space Warps. You can follow Aprajita on x at @aprajitaverma.

Anupreeta More @anupreeta
Anupreeta is an astronomer at IUCAA, India. She has been captivated by gravitational lenses ever since she first saw one. She likes to find these rare systems and study them to learn more about the mysterious dark matter and how it influences the galaxies hosted within. She led the first Space Warps project using data from the CFHT Legacy Survey. She's interested in developing better algorithms, for instance, combining machine learning with citizen science to find more lens systems with upcoming surveys. You can follow Anupreeta on x at @anupreeta

Philip Holloway @philholloway
Phil H is an astronomer-in-training at the University of Oxford, where he's pursuing a PhD in Astrophysics. He took his undergraduate degree at the University of Cambridge where amongst other things he studied microlensing (a different type of gravitational lensing) with data from the Zwicky Transient Facility. He's now focussed on searching for strong gravitational lenses and would love the help of citizen scientists to improve our lens finding algorithms.

Phil Marshall @drphilmarshall
Phil is an astronomer at the Kavli Institute for Particle Astrophysics and Cosmology, Stanford University. After deciding he liked doing maths and physics problems at school and university enough to want to make up his own questions, Phil did a PhD at Cambridge University on using gravitational lensing to map the distribution of dark matter in galaxy clusters. Since then he has spent ten years as a research scientist using strong lenses to weigh galaxies, and investigating automated strong lens detection. He knows very well how hard it is to teach a robot to spot lenses - or at least, how hard it is to teach them not to be confused by large numbers of galaxies that are not lenses. You can follow Phil on x at @drphilmarshall.

Mike Walmsley @MikeWalmsley
Mike is an astronomer at the University of Toronto. You might know him from Galaxy Zoo, where he is the Technical Lead and is often nudged to upload more data because "we've run out of galaxies".

Karina Rojas @Krojas26
Karina is an astronomer at FHNW, Switzerland. From early in her career she had an interest in gravitational lensing. During her postgraduate studies she focused on the analysis of QSO microlensing to study the inner structures of those objects. After her PhD she switched the focus of her research to the galaxy-galaxy strong lensing search using machine learning algorithms. Since then she has been working to improve the algorithms to find lenses but also to understand how humans (experts and not experts) bias the searches through the visual inspection stages.

Tom Collett @Tom
Tom Collett is an astronomer at the University of Portsmouth. He has spent his entire career working on strong lensing and is particularly interested in using them to probe the dark matter and dark energy that seem to dominate our Universe but are nothing like the ordinary matter we interact with here on Earth. If you find a double source plane lens Tom will be super excited.

Tian Li @SkyLi
Tian is a PhD student at the Institution of Cosmology and Gravitation, University of Portsmouth. He’s particularly interested in the cosmological application of strong gravitational lensing systems. Outside of his main research, he enjoys in Astrophotography and science image visualization.

Giulia Despali @saiph87
Giulia is an astronomer at the University of Bologna. She did a PhD at the University of Padova on creating numerical simulations to describe the evolution of the Universe. She then worked at research centers in France and Germany, where she spent the last years combining gravitational lensing and computer simulations to detect the mysterious dark matter component of our Universe. Having spent a lot of time modelling strong galaxy-galaxy lenses, she knows how hard it can be to find them, but also how exciting it is when you do!

Space Warps Moderators

Elisabeth Baeten @ElisabethB
Els has always been interested in science, and astronomy in particular, but choices and career moves steered her in a very different direction. So, when she discovered GalaxyZoo, it was the chance of a lifetime to get seriously involved. This resulted in, among other things, moderating the discussion in several different projects (Solar StormWatch, Old Weather, IceHunters and recently for GalaxyZoo Talk) and classifying in many more. Before GalaxyZoo came along she had only some vague notions of what a gravitational lens was, but she quickly became intrigued by them and spent hours searching the SDSS images for potential lenses. She is looking forward to doing some serious lens hunting!

Christine Macmillan @Budgieye
Christine, a retired biologist and planetarium presenter, participates in citizen science, classifying in Galaxy Zoo and posting in the TALK forum. She has always been fascinated by the sky, starting with the Moon when a small child, then the solar system and stars, and then learning about galaxies and gravitational lenses in a natural progression of expanding horizons.

Claude Cornen @c_cld
Claude was an IT development manager and is now retired after a long professional life in the French consumer loan business. He could then take his time reading, learning history of sciences and attending lectures on astrophysical topics. In volunteering on Zooniverse projects , he uses his ability in data mining to respond to calls for "wanted" objects in the Galaxy Zoo forum like "peas", "overlaps", "AGN with ionized clouds", and "strong gravitational lenses."

Zooniverse Team

Of course none of this would even be possible without the fantastic work of the Zooniverse team, past and present, both in developing the platform and systems that this project runs on and uses but also for considering all of the Space Warps requested features and answering our many questions. Thanks to you all!

Amazing Volunteers participating on Space Warps

The above statement is even more true for our vibrant and committed community of citizen scientists. We are eternally grateful for your commitment and time to this project, you make and are Space Warps!!
