Cosmology Talks is hosting a mini-workshop on Thursday 10 April at 18:00 UTC about DESI DR2 Cosmology.

The workshop will be purely discussion based, and framed around the recent DESI DR2 papers and the talks listed below. Most of the speakers from the talks will be present, as well as some invited experts on related fields.

Important! It is not expected that the talks and papers are fully understood by all participants, but the contents of either the relevant Cosmology Talks video or video 1 and video 2 from DESI’s YouTube channel will be assumed to be common knowledge of all participants before the discussion begins. This provides a common starting position for discussion among all attendees.

Questions/thoughts are, however, welcome on any of the recent DESI papers, or talks listed below.

Cosmology Talks: DESI 2025 – Cosmology Results from DR2 BAO (Garcia-Quintero & Martini)

DESI’s YouTube Channel:

1. DESI shakes up the dark Universe: An overview
2. DESI DR2 Results: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints

3. Extended Dark Energy analysis using DESI DR2 BAO measurements
4. DESI DR2 Baryon Acoustic Oscillations from Galaxies and Quasars
5. DESI DR2: Validation of the Lyman alpha BAO analysis using synthetic datasets
6. Dark Energy Spectroscopic Instrument Survey Data Release 1
7. DESI DR2 results: Baryon Acoustic Oscillations from the Lyman-alpha forest
8. Combined Clustering and Weak Lensing from the DESI Year-1 Dataset and Stage III Lensing Surveys
9. Neutrino masses from the latest DESI results

The schedule is (starting at 18:00 UTC):

• 10 minutes (approx) introducing the workshop format.
• 50 minutes discussion in one Zoom room.
• 10 minutes (approx) break time.
• 50 minutes of multiple discussions, in breakout rooms, based on ideas that arose during the earlier discussion.

Pre and post-discussion will take place in the Cosmo Discussion Mattermost space, in the Cosmology Talks channel. The speakers and invited experts will also be present there to ask questions.

Participation at the workshop is open to all cosmologists and researchers from neighbouring fields.
