ALMA/45m/ASTE Users Meeting 2018 26-27 December, 2018 NAOJ, Mitaka, Japan Science Advisory Committee (SAC) Report On behalf of JSAC/EASAC Kotaro Kohno Univ. of Tokyo
Roles of ASAC • Make appropriate recommendation and advice to the ALMA board on ALMA issues from scientific viewpoints • in order to maximize the science productivity of ALMA • based on intimate communications with user community (and JAO, ARCs). – è regional SACs (JSAC in Japan, EA-SAC for EA countries, etc.)

ALMA board charges to the ASAC for October 2018 f2f meeting (1) • Permanent charges 1. Assessment of the performance of ALMA scientific capabilities 2. Assessment of the technical aspects of the ALMA system performance 3. Assessment of the science outcomes from ALMA 4. Recommendation of ways to maximize ALMA’s scientific impact 5. Reporting on operational or scientific issues by the wider community (ANASAC, ESAC, EASAC) 6. Assessment of the scientific impacts of the ALMA development program
ALMA board charges to the ASAC for October 2018 f2f meeting (1) • The ad-hoc charges for this meeting 1. The ASAC should identify the main science cases that would require joint observing proposals between ALMA and other facilities, especially JWST. 2. The ASAC should suggest additional ways to further engage the community in proposing for high frequency observations. 3. The ASAC should begin to discuss the proper metric to measure the success of the distributed proposal review model pilot, currently slated for the October 2019 ACA delta call (Cycle 7.5).
Recent issues discussed in ASAC (1) • Cycle 6 proposal review – heavy reviewer workload; some planned changes were discussed (see also Ad-hoc #3) – resubmitted proposals? – potential bias (gender, etc.)? è first names will be removed for the Cycle 7 review • Archive/Imaging pipeline – Mosaic imaging problem • promotion of ACA stand-alone observations – high-frequency and polarimetry
Recent issues discussed in ASAC (2) • Joint proposals (Ad-hoc #1) – no clear resolution; is there any new classes of sources where joint proposals would be necessary? – time critical events or transients è ToO and DDT can work. – (Board still sticks to this?) • High frequency observations – cross-band calibration will be the key to offer Band 9 and 10 as standard mode in Cycle 8. – promote B-ranked high frequency proposals ahead of A- ranked low frequency proposals when the weather conditions are appropriate • to improve the completion rate of high frequency programs • the disappointment of PIs who are repeatedly awarded time but never get data is seriously discouraging for future submissions
Recent issues discussed in ASAC (3) • Distributed proposal review (DPR) model – a contentious subject during the last two ASAC f2f meetings in 2018; ASAC is coherently against it, whereas JAO strongly eagers to implement it – ACA delta call (Cycle 7.5) will be the opportunity to test the DPR model; user/reviewer feedback will be important. • Array configuration cycle (2yr vs 3yr) – another topic which was discussed through the last two ASAC f2f meetings – ASAC prefers 2 yr cycle (e.g., for faster turn-around time, which is essential for student/young post-doc) – but 3 yr will also be useful for high frequency promotion
JSAC • Regional SAC for ALMA project • also plays a role as SAC for NRO 45-m and ASTE 10-m telescopes • Members from projects (NAOJ Chile Observatory and Nobeyama Radio Observatory): – S. Sakamoto, A. Gonzalez, M. Fukagawa, D. Iono – S. Sakamoto (ASTE) – K. Tatematsu (NRO)
Recent issues discussed in JSAC • Preparation for Japan Science Council Master Plan 2020 – Science book for “ALMA2” was discussed (author distributions, etc.) – now Science book becomes mostly ready! • Operation of NRO 45-m telescope – operation plan with the limited budget conditions • Operation of ASTE 10-m telescope – recovery status and plan for 2019 science operation We need your feedback!
