چکیده
National Astronomical Observatory is an inter-university institute serving as the national center for ground based astronomy offering observational facilities covering the optical, infrared, radio wavelength domain. NAOJ also has solar physics and geo-lunar science groups collaborating with JAXA for space missions and a theoretical group with computer simulation facilities. The outline of NAOJ, its various unique facilities, and some highlights of recent science achievements are reviewed.

Maraghe Observatory and an Effort towards Retrieval of Architectural Design of Astronomical Units
Maraghe observatory was built by such engineers as Moayiededdin Orozi etc. under supervision of Khaje Nasireddin Tousi in 7th century AH. The most significant feature associated with Maraghe observatory is the fact that architecture is employed to achieve astronomical purposes in this site. The reason for preferring observatory by astronomers was the fact that these units are superior to wooden...

متن کاملun 2 00 3 Linear Polarization Observations of Water Masers in W 3 IRS 5
We present a magnetic field mapping of water maser clouds in the star-forming region W3 IRS 5, which has been made on the basis of the linear polarization VLBI observation. Using the Very Long Baseline Array (VLBA) at 22.2 GHz, 16 of 61 detected water masers were found to be linearly polarized with polarization degrees up to 13 %. Although 10 polarized features were widely distributed in the wh...
متن کاملA Study of the Distribution of Star-Forming Regions in Luminous Infrared Galaxies by Means of Hα Imaging Observations
We performed Hα imaging observations of 22 luminous infrared galaxies to investigate how the distribution of star-forming regions in these galaxies is related to galaxy interactions. Based on correlation diagrams between Hα flux and continuum emission for individual galaxies, a sequence for the distribution of star-forming regions was found: very compact (∼ 100 pc) nuclear starbursts with almos...
