Bando per osservazioni al TNG

AOT 27 (2013A) is now open for proposals Applications for observing time for the period February 1st, 2013 - July 31st, 2013 are solicited and should be submitted by Friday 19th Oct, 2012, 13:00 UT

TNG is a 3.58m optical/infrared telescope located at Roque de Los Muchachos Observatory in the island of La Palma (Canary Island). Its primary mirror is corrected by Active Optics and it is equipped with 3 instruments which offer imaging and spectroscopy, spanning the optical and near infrared wavelengths range.


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.


***  SARG AT TNG   ***

Atarting AOT 27 the visible spectrograph SARG will not be offered. After years of service at TNG it is starting its decommissioning phase. Users are invited to consider the use of Harps-N for visible echelle spectroscopy.

***  HARPS-N AT TNG   ***

Harps-N @ TNG is a high resolution, high stability visual echelle spectrograph suited for radial velocity measurement with sub m/sec accuracy.

The instrument, a copy of Harps @ 3.6m ESO Chile with some upgrades, is now operational.

See our web pages for info on the instrument and its usage.

In addition, the Harps-N Corsortium (see web pages) will carry out Guaranteed Time Observations (GTO) which will have a list of protected targets, which cannot be proposed for observation by other users. The list of protected targets can be found at this page (

***  PAOLO AT TNG   ***

A new observing mode for DOLORES is offered starting this semester. A polarimetric add-on (PAOLO) uses a double wedged Wollastone and a rotating quarter-lambda plate to allow photometry and spectroscopy in polarimetric mode. Calibration of this mode is still ongoing and users will have to check our pages for news. Please refer to for further information.

***  ROS2 AT REM   ***

Due to the unexpectedly long integration/commissioning phase of the instrument ROS2, the semester 2012B (AOT26) is currently suffering a large amount of technical downtime, due to unavailability of the visible camera. While we reckon the present call for proposal will be in a regime state, proponents of last semester which suffered from this situation will be prioritized in case they decide to resubmit their program.

ROS2 is the new visible imaging camera. The new set of filter will be Sloan/SDSS g', r', i', z'. The camera is capable of obtaining the 4 images in the 4 different filters at the same time, using dichroics. See the REM web pages for more details in the Instrumentation section.

Application forms and detailed instructions can be downloaded from

the TNG web pages ( ).

The INAF time allocation committee welcomes proposals from foreign researchers/institutes which, alike all other proposals, will be judged strictly on their scientific merit.

Galassia satellite? No, sono solo di passaggio


Molte delle galassie che “orbitano” intorno alla Via Lattea non sono satelliti, ma solo di passaggio e, forse, non rimarranno mai intrappolate nel campo gravitazionale della nostra galassia. A rivelarlo, le precisissime misure di velocità del telescopio spaziale Gaia

L’onda d’urto dell’uomo che corre


Il telescopio spaziale Hubble ha ripreso questa immagine di HH 45. Questo oggetto si trova nella nebulosa Ngc 1977 che fa parte della nebulosa Uomo che corre, o Running Man Nebula. Hubble ha osservato questa regione per cercare getti stellari e dischi di formazione planetaria attorno a giovani stelle ed esaminare come il loro ambiente influisce sull'evoluzione dei dischi stessi

Così esplode una luminosa variabile blu


Quali processi portano le stelle “variabili S Doradus” (Lbv, in inglese) a esplodere come supernove? Attraversano o meno la fase di stelle di Wolf-Rayet? Per indagare il fenomeno, un team di astronomi guidato da Sabina Ustamujic dell’Inaf di Palermo ha messo a punto un modello idrodinamico tridimensionale che segue l’evoluzione del materiale espulso dall’esplosione di una supernova prodotta dal collasso del nucleo di una stella Lbv
