Collaboration and Sponsors

While we often picture astronomers as lone souls peering through a telescope, building, carrying out, and analyzing an ambitious survey such as DES requires a large, coordinated team.  DES is an international project with over 400 scientists from 25 institutions in 7 countries, who have come together to carry out the survey.  Our team of scientists comprises university faculty and researchers, laboratory and observatory staff scientists, post-doctoral researchers, and graduate and undergraduate students. The support staff are also a critical part of the team: they make it possible for our scientists to travel to Chile to observe for the survey and to travel to conferences and collaboration meetings to discuss the latest results.




Science Working Groups and Conveners

Our scientific efforts are organized into Science Working Groups, each of which is tasked with coordinating and leading analyses and projects that feed into the larger questions of cosmic acceleration and expansion as well as other science topics. The co-coordinators of the Working Groups make up the Science Committee, which coordinates the analysis across working groups. The Science Working Groups, and their conveners, are:

Galaxy Clusters: Tesla Jeltema & Kathy Romer
Supernovae: Masao Sako & Rick Kessler
Weak Lensing: Daniel Gruen & Michael Troxel
Theory and Combined Probes: Elisabeth Krause & Eduardo Rozo
Milky Way: Alex Drlica-Wagner & Jennifer Marshall
Strong Lensing: Adam Amara & Brian Nord
Large-Scale Structure: Martin Crocce & Ashley Ross
Simulations: Katrin Heitmann & Risa Wechsler
Redshift: Tamara DavisBen Hoyle & Enrique Gaztanaga
Galaxy Evolution & QSO: Manda Banerji, Will Hartley & Richard McMahon
Transients & Moving Objects: David Gerdes & Marcelle Soares-Santos

The Science Committee is coordinated by Scott Dodelson & Gary Bernstein.

Joshua Frieman (Fermilab and U. Chicago/KICP) is the Director and Spokesperson of the DES Project (succeeding John Peoples from FNAL). He leads the Project/Collaboration Office, which oversees all aspects of the Project and Collaboration. The Management Committee oversees collaboration affairs and oversees a number of committees:

Publication Board: Tesla Jeltema
Membership Committee: Eusebio Sanchez
Speakers Bureau: Brenna Flaugher
Early Career Scientists: Antonella Palmese, Rutuparna Das, Ting Li, Stephanie Hamilton, TomMclintock
Education and Public Outreach: Kathy Romer, Brian Nord, Rachel Wolf
Diversity & Inclusion: Brian Nord & David James
Collaboration Meeting Steering Committee: Tesla Jeltema

Executive Committee

The Executive Committee manages all aspects of the operation of the survey, from data management to camera operation to science computing. It focuses on:

Data Management
Observing Systems
DECam Operations
Survey Strategy
Science Analysis Computing
Data Release

External Collaborations

We also collaborate with other scientists and projects to carry out joint studies including the VISTA Hemisphere Survey, the South Pole Telescope Survey, STRIDES, and others.

At each institution, a number of scientists share their knowledge of the cosmos and their perspectives on science with the general public. DES is committed to contributing to both our local communities and the global community.
