چکیده
Most distant and ancient supernovae discovered by the Subaru Telescope. In the image, which show the Subaru Deep Field, numerous supernovae related to white dwarfs were found, and ten of them had exploded more than ten billion years ago. This discovery gives an important clue to study how the heavy elements created in the ancient universe (Graur et al.

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...

We report on the discovery of a new potential galaxy threshing system in the COSMOS 2 square degree field using the prime-focus camera, Suprime-Cam, on the 8.2 m Subaru Telescope. This system consists of a giant elliptical galaxy with MV ≈ −21.6 and a tidally disrupted satellite galaxy with MV ≈ −17.7 at Based on data collected at Subaru Telescope, which is operated by the National Astronomical...
