Nobeyama RadioObservatory
Ken TatematsuSummary• Three Legacy programs (FUGIN, COMING, Star Formation) haveofficially finished in 2017 May. 3D FITS data will be made public
on 2018/5/31. Papers are coming.
• We started Call for Development Proposals.
• Target is High-Performance Telescope (> 30 papers with < $3M
operation budget)• We are making efforts to make 45m telescope more productive.
• Efforts to increase the proposal number• Efforts to increase the refereed paper number• We received two Milestones: IEEE and IECIE

Change of Director• Masao Saito (2014 Jul-2017 Feb)
• Hideyuki Kobayashi (Acting Director 事務取扱, 2017 Mar-Jun)• Ken Tatematsu (2017 Jul-2021 Jun)Current achievement• High telescope efficiency of the 45-m telescope (surface,FOREST, spectral window mode, etc) lead by Masao Saito,Tetsuhiro Minamidani• Completion of three legacy programs (FUGIN, StarFormation, COMING) in 2017 May• It is a time to output outstanding scientific results!

Legacy Programs• Three legacy programs officially ended at the end of 2017May (practically terminated in 2017 March because of themaster collimator failure)• A total of ~3000 hrs were allocated, and ~2000 hrs wereuseful.
• We help the Legacy Review on Sep 26-27 (Fujisawa [chair],Arimoto, Inutsuka, Takakuwa, Komugi, Oka)

PASJ Special Issue: Legacy and FOREST• Recommended by the Legacy Review• Submission recommended by 2018/08/01• Acceptance deadline 2018/12/01• Electrical version is published one by one after acceptance• Print version 2019/03/25• On the other hand, some reviewer suggest submitting to not
only PASJ but also to Nature or Science etc depending on theimpact of results.

Effort to reduce the operation budget• From this fiscal year, we introduced Call for Development
Proposals, so that Nobeyama developments concentrate on
open-use capability enhancement only. Furthermore, werequest that PI is asked to prepare the necessary
development budgeting. This fiscal year, we accepted theeout of 11 proposals (Taiwan Band1 RX ,three frequency
simultaneous observation with HINOTORI, FMLO）• We continue slimming down, started by Masao Saito. On theother hand, we wish to secure the minimum resource foropen use operation.

45m Hardware• Master collimator broken 2017 mid March, reinstalled in 2017
August, commissioned, and now in use.
• FOREST• Spectral window mode (4 lines with 4 beams in 2 polarizations etc)
• On-On obs ==> receiver TZ decommissioned• wider band in LSB：4-8GHz --> 4-8GHz, 7-11GHz• Z45 for the open use• Telescope repainted（FY2016, 2017）• Renewal of millimeter calibration system（FY2016）• Renewal of RX selection mirrors

45m Software• New observing table software “nobs” (Python based)
replaced “zobs” (Java based) to allow “FOREST spectrum
window mode”• Increase of remote operation sites (Kagoshima, TaiwanASIAA)• Nobeyama 45m Science Data Archive opened in August
https://nobeyama-archive.nao.ac.jp/user/index.html• 45m/ASTE data reduction with CASA; test for pipeline

Nobeyama Solar Polarimeters• Stable observations, but 2 GHz observation continues to beaffected by interference.
• Accident in June
• Safety was reconsidered• Installed a stable work stage• Safety rule: maintenance work by two or more persons, hardhat, etc• Repair was suspended before installation of the new stage, and 9.5 GHz data
had a problem during this period.

Milestones• IEEE Milestone• 2017 Jun 14 @ Tokyo• 2017 Jun 16 @ Nobeyama• IEICE (The Institute of Electronics, Information andCommunication) Milestone電子情報通信学会マイルストーン

Public Outreach• Opening of NINS Exhibition Room 2017 Apr 29• We re-use the Nobeyama Millimeter Array control building forexplanation of five NINS insitutes. It has 4D2U theater.

NumberCall for Proposals• Effort in Call for Proposals• We only had one deadline for regular programs for 2016-2017, but
resume to have two deadlines for 2017-2018.
• For many years, we had only one deadline for short programs, but
started to have two deadlines from this season 2017-2018.
• By using personal network, we made our effort to increase proposal
from foreign countries.

Call for Proposals• Status of 2017A• # proposals for 2016A was 35, but we received 46 proposals for semester
2017A.
• # proposals from foreign countries for 2016A was 5, but we received 12 for2017A• # proposals from China mainland have been zero there years, but wereceived 6 proposals (2 was accepted).

• Status of 2017B• #regular = 20 (#foreign = 8!!!, Chine=3, US=2, Taiwan/UK/Australia=1)• #short=5 (#foreign=0)• We continue to make effort to increase the open use time(currently ~ 3000 hr/y)Refereed publication form 45m telescope

Importance of the 45-m telescope• ALMA will need good molecular-line tracers to see the densest
cold ISM, but depletion of molecules onto dust should be serious.
• N2D+, N2H+ (relatively) free from depletion will be very powerfultools.
• D/H such as N2D+/N2H+, DNC/HNC is being confirmed to be goodsignpost of the onset of star formation in cold cores.
• 70-GHz (B2) , 140-GHz (B4), 200-GHz (B6) are important for
deuterated molecules. 45-m has receiver T70 for 70 GHz.
• Now, ALMA-EU and ALMA-NA is proposing B2 receiverdevelopment.

Nobeyama as ALMA Pathfinder• Nobeyama Large Program (PI=Tatematsu, # of coI ~ 200,350 hr over 2 yr) will pick up cores very close to starformation using deuterated molecules for Planck cold clumps.
Started on 2017 Dec 8. This will provide good targets forALMA.
• NRO Director strongly wishes to continue open use operationof 45m at least 10 years from now, by achieving the highcost-performance telescope, although NAOJ top
management is asking to stop it by 2022 March.

Problems• No assistants for Dec 28-Jan 3. We started GTO rather thaninternal programs. Legacy finished.
• Dec 29-Jan 3 needs to be filled with observatory PI or expert.
• This time, large (PI=Tatematsu) have assigned time on Dec
24, 25, Dec30-31, Jan 1-3.
• Can Large and GTO (from development program) be asked tohave expert users OK for Dec 29-Jan 3, and Golden Week?

Grade A for 45m telescope?
• Professor Satoshi Yamamoto suggested Grade A (guaranteerms noise level) one year ago• It may continue very long time, taking into account 45m
situation (pointing due to winds)• Re-allocation: Cancelled observing time due to unexpected
instrumentation/telescope failure will be re-allocated.
Observing time surrendered to backup programs due to bad
weather also will be compensated.
• Grade A (more generous weather compensation)? 1520%?Excluding Large programs?

Thank you!
