The deadline for proposal submission for Period 113 (1 April 2024 - 30 September 2024) was 26 September 2023: 782 valid proposals were submitted, noting that submission of Large Programmes is not open in odd Periods. On the VLT, the most demanded ESO instrument was MUSE with a request of 266 nights, followed by X-Shooter with 169 nights and ERIS with 138 nights. HARPS/NIRPS on the ESO 3.6-metre telescope was the most demanded instrument at La Silla, with a combined request of 122 nights.
Period 113 Proposal Submission Statistics
In Paranal, the telescope with the highest oversubscription is Yepun (UT4), with a total request of 474 nights, followed by Melipal (UT3; 309 nights). Similar to P112 and previous Periods, 85% of programmes requested Service Mode in P113 at the VLT.
In P113 the submission of joint programmes for VLT/I-ALMA and VLT/I-XMM was opened.
The distributed peer review (DPR) in P113 followed the setup introduced in previous Periods. Thus the DPR channel processes proposals requesting a total telescope time of 16h or less, and will evaluate 50% of all submitted proposals, covering 20% of all the requested time. The rest of the proposals will be reviewed by the Observing Programmes Committe.
The percentages of submitted proposals across science categories were:
- Cosmology and Intergalactic Medium 10.1%
- Galaxies 27.0%
- Interstellar Medium, Star Formation, and Planetary Systems 32.1%
- Stellar Evolution 30.7%
