The Cosmostatistics Initiative

The Cosmostatistics Initiative (COIN) is a worldwide  endeavour aimed to foster interdisciplinary collaborations to solve data-driven scientific challenges.

The group is co-lead by Rafael S. de Souza (U. Hertfordshire, UK), Alberto Krone-Martins (UC Irvine, USA) and Emille E. O. Ishida (CNRS, France).

Researchers willing to join are welcome to contact any of the chairs!

COIN Residence Programs

An unstructured meeting, offering opportunities for collaborative research, learning, and transference of skills.


The CRPs are composed by  young and senior researchers from  astronomy, statistics, computer science and related disciplines alike.


The group utilizes a management model somewhat similar to technological start-ups. Our dynamic, non-hierarchical, and people-centric approach enables innovation in scientific research, while helping its members to enhance their career paths.


A complete report of COIN projects, results and previous meetings can be found in the Projects page.

Portugal is a country located on the Iberian Peninsula, in southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population.

Portugal has left a profound cultural, architectural and linguistic influence across the globe, with a legacy of around 250 million Portuguese speakers around the world, the majority of them in Brazil.

Lisbon hosted the CRP #1, back in 2014, and we are happy to have gone full circle and return to the country that served as an inspiration to us all from the beginning.

Our venue:
Villa São Francisco
Rua Alto Das Necessidades
Cabanas / Quinta do Anjo
2950-089 Palmela

Code of Conduct

COIN is composed of members from around the globe with a diverse set of skills, personalities, and experiences. This is one of the characteristics which makes it unique and fruitful.

We require participants to follow these guidelines which help steer our interactions and strive to keep the CRPs an enlightening experience for all members involved.

The official language of CRP#7 is English.


CRP #7 will be a harassment-free environment for everyone, regardless of gender, sexual orientation, disability, physical appearance, body size, race, nationality or religion.

Please bring any issues to the confidential attention of the workshop organizers.


Be receptive to constructive comment and criticism, as the experiences and skill sets of other members contribute to the whole of our efforts.

Be thoughtful when addressing the efforts of others, keeping in mind that often times the labour was completed simply for the good of the group.

Be good and respectful to each other.

Given the informal nature of the program, be perceptive about eventual help needed in the organization and maintenance of the household tasks. Remember that there is no room service or catering. Keeping things clean and organized is up to the group itself.

CRP #7 is a strictly non-smoking event. Smoking is not allowed anywhere inside the venue.

Participants sharing a room should pay attention to tidiness, personal hygiene, sleeping hours and noise. In the common areas, there is no time limit and you can keep working through the night, if you wish to.
Publication and authorship:

The mere participation in one of the CRPs does not guarantee authorship in COIN papers.

Publications developed during the CRPs are lead by volunteer participants who commit to the implementation of all stages of the project during and after the meeting.

All participants who contribute to development of a project will be included in the author list. The order of the authors is decided by the project leader, in common agreement with the chairs,  once the paper is finalized.

Scientific results

Project 1:

ELEPHANT: ExtragaLactic alErt Pipeline for Hostless AstroNomical Transients

Pre-print - Project Page - Press release

ELEPHANT represents an effective strategy to filter extragalactic events within large and complex astronomical alert streams. There are many applications for which this pipeline will be useful, ranging from transient selection for follow-up to studies of transient environments. The results presented here demonstrate the feasibility of developing specially crafted pipelines that enable a variety of scientific studies based on large-scale surve
