AOT 38 TNG REM Call for Proposal. Deadline 18.05.2018


AOT 38 (2018B) is now open for proposals

Applications for observing time for the period

October 1st, 2018 - March 31st, 2019

are solicited and should be submitted by
Friday, 18th May, 2018, 12:00 UT

The available time offered at TNG via INAF-TAC is 12 (twelve) nights in the AOT38 semester.
A detailed schedule breakdown is reported at the bottom.

We will be accepting (few) Director Discretionary Time proposals during the whole semester, which will be judged by the TNG staff in few days. These observations will be performed in Service Mode only.

TNG is a 3.58m optical/infrared telescope located at Roque de Los Muchachos Observatory in the island of La Palma (Canary Islands). Its primary mirror is corrected by Active Optics and it is equipped with instruments for imaging and spectroscopy, spanning the optical and near infrared wavelengths range.
The offered instruments are: HARPS-N, NICS, DOLORES and GIANO-B (GIANO in Nasmyth B).
The observing mode GIARPS, simultaneously combining HARPS-N and GIANO-B, is also offered (see below).

REM is a 60 cm robotic telescope located at La Silla ESO site (Chile) which can observe simultaneously with a visible and an infrared camera. The observations will be carried out in unmanned, queuing mode. INAF-TAC will allocate 1000 hours of observations.
REM is equipped with ROS2 visible camera and REMIR infrared camera. The two are observing simultaneously thanks to a dichroic.
ROS2 will produce simultaneous images in the four Sloan-like passbands g, r, i, z. Charged time is therefore not the sum of ROS2 and REMIR but the highest of the two.
For details, see

NOT is a 2.56-m telescope, also located at Roque de Los Muchachos Observatory, next to the TNG. Offered instruments are ALFOSC (UV-optical imaging, polarimetry and low-resolution spectroscopy), NOTCam (NIR imaging, polarimetry and low-resolution spectroscopy), FIES (High-resolution, high-stability optical spectroscopy), MOSCA (High-resolution, high-efficiency UV-optical imaging), STANCam (Standby CCD imager).

The Italian community can ask 20 (twenty) nights on the basis of the exchange time agreement (see below).

All proposals will be judged strictly on their scientific merit.



In the era of mature 8m-class telescopes, and with 40m-class telescopes approaching the event horizon, it is mandatory to define compelling scientific programs that justify the investments that the Italian astronomical community is making to maintain TNG operative and competitive. In the AOT37 call we offered the possibility to run Large Programs. Two Large Programs are now using the GIARPS configuration at the rate of 47 nights per semester.

Large Program proposals cannot be submitted answering the AOT38 call. The PIs of ongoing Large Programs are not requested to send a progress report in this call.


In this call TNG opens observing time to less time-demanding programs, but still having the need to extend over a few consecutive semesters to be completed and/or to ensure the necessary follow-up.

The "Long Term" programs must be able to strictly address major open problems in modern astrophysics, characterizing the TNG role in the next 1-2 years. The basic features of these "Long Term" programs are:

  • All topics in modern astronomy are eligible.
  • Programs can only use any of the permanently instrument installed and commissioned on TNG: DOLORES, NICS, HARPS-N, GIANO-B, also in the so-called GIARPS mode.
  • Programs may extend up to 3 semesters, and use a maximum of 30 hours per semester.
  • The Principal Investigator (PI) and least 50% of the participants must be affiliated to a Italian Institutions. In the field of optical/infrared observations of Target of Opportunity objects, a worldwide collaboration is particularly encouraged. We emphasize the possibility to submit joint proposals between the Italian and Nordic communities in the framework of the common TNG-NOT offer (see below), thus exploiting the simultaneous use of NOT and TNG.
  • The INAF-TAC can reduce a Long-Term Program to normal one to be executed in a single semester.
Depending on the number of the accepted Long-Term programs, the next TNG call could be opened on a 1-year basis.
