Abstract:
We present the results from a survey, designed to investigate the
accretion process of massive young stellar objects (MYSOs) through
near infrared narrow band imaging using the H2 ν=1-0 S(1)
transition filter. A sample of 353 Massive Young Stellar Object
(MYSO) candidates was selected from the Red MSX Source survey using
photometric criteria at longer wavelengths (infrared and
submillimeter) and chosen with positions throughout the Galactic
Plane. Our survey was carried out at the SOAR Telescope in Chile and
CFHT in Hawaii covering both hemispheres.
Description:
The Northen sample were obtained with the CFHT, Mauna Kea, Hawaii,
using the Wide-field InfraRed Camera (WIRCam) between 2010 August and
2012 August.
The Southern sample have been observed with the Southern Astrophysical
Research Telescope (SOAR), Cerro Pachon, Chile, using the Ohio State
Imager/Spectrometer (OSIRIS) camera between 2011 March and 2011 June
and the Spartan camera between 2011 August and 2012 December.
