CFHT's scientific staff
is composed of
resident, visiting astronomers, a QSO specialist,
and remote observers. The science staff is involved in several of the
scientific activities ongoing at CFHT.
Daily Science Activities
The main scientific activity at CFHT consists of the execution of
observations for the accepted science programs. This is done via Queue Scheduled Observing (QSO) Four instruments are
available in the QSO mode.
a wide 1 degree field 0.18" pixels imager.
- WIRCam, a wide-field infrared
camera (20'x20', 0.3" pixels).
- ESPaDOnS, an Echelle
SpectroPolarimetric Device for high resolution spectroscopy and
- Sitelle, an optical imaging Fourier
transform spectrometer (IFTS).
Important results obtained from CFHT data are often covered in the
News. Please visit the News
section for our
CFHT data archive at CADC
Observations obtained with the Canada-France-Hawaii Telescope from
February 1990 to the present are archived at the CADC
The CFHT archive at CADC allows searches by observation meta-data, such
as object name and run ID, and presents the results of the search in
a tabular format. Users can request and receive archival data and, for
some imaging data, previews of CFHT data.
Instrument development is also
done at CFHT.
- The MegaCam filter upgrade has been completed.
- SPIRou, a near-IR spectropolarimeter and high-precision velocimeter,
expected to arrive in 2017
- GRACES, a link from Gemini to ESPaDonS, which has been successfully
commissioned in 2014 and is offered by Gemini starting with semester 2015B
- ngCFHT, now renamed MSE, a project for a new 10-m class telescope
The science staff also participates in the development and maintenance
of the different data reduction pipelines at CFHT in collaboration with the
- Elixir, the data reduction pipeline for MegaCam.
- Upena, the pipeline for Espadons
- Opera, an open-source software pipeline for the processing of echelle spectra
- Iiwi`, the pipeline for Wircam.
The science staff also participated in the Observatory Automation Project (OAP)
CFHT astronomers conduct their own science projects and
publish research papers.
A few astronomers have written articles on various astronomical topics
for the general public in the local North Hawaii News weekly magazine.
CFHT's astronomers organize and attend seminars
presented on a semi-regular basis.
CFHT's library is a great source of information
that includes a database of
International Astronomy meetings and a
core list of Astronomy books, both compiled by our former librarian. CFHT's
Information Bulletins, important information on
working at high altitude, and much more are also available.
