Help & FAQs

What is COIN?

The Cosmostatistics Initiative (COIN), an international working group built under the auspices of the International Astrostatistics Association (IAA), aims to create an interdisciplinary environment where collaborations between astronomers, statisticians and machine learning experts can flourish.

COIN is designed to promote the development of a new family of tools for data exploration in astrophysics and cosmology. The group is led by Rafael S. de Souza and researchers willing to join are welcomed to contact him at

What is Overleaf?

Overleaf is an online collaborative writing and publishing tool. It allows you to collaborate online with coauthors and greatly simplifies the process of creating and writing a LaTeX document. Overleaf's custom templates allow authors to submit their papers directly to many journals and repositories via Overleaf, including the arXiv.

How can I sign up for my free Overleaf Pro Account?

If you're already a member of COIN, you should have automatically received an invite to the email address you used to register with COIN. If this invite hasn't arrived (please check your spam folder), please get in touch and we'll look into it for you.

What's a "Pro" account, and what happens when the one-year period is over?

At the end of the one-year trial, you may choose to continue as Overleaf Pro subscriber (current cost $8/mo), or your account will revert to the Overleaf Free plan. Any data or papers saved in Overleaf will continue to be accessible.

Special Awards: After the end of the first year, 10 award extensions of the Pro account will be granted to those users who have been particularly active in promoting and using the Overleaf platform.

For more information about the different Overleaf plans, please see this page, and if you have any questions about this please let us know.
