1°- and 25-scale interferometric surveys in the northern sky at 5 GHz

An absolutely calibrated survey of polarized emission from the northern sky at 1.4 GHz

A new polarization survey of the northern sky at 1.41 GHz is presented. The observations were carried out using the 25.6 m telescope at the Dominion Radio Astrophysical Observatory in Canada, with an angular resolution of 36. The data are corrected for ground radiation to obtain Stokes U and Q maps on a well-established intensity scale tied to absolute determinations of zero levels, containing ...

The stock surveys and distribution of Haemulidae in the northern Oman Sea (Sistan and Baluchistan province)

This research was carried out to assess the amount of the biomass and Catch Per Unit of Area (CPUA) and also to determine the distribution pattern of the haemulidae family in the northern parts equipped with trawl floor area cape of meydani ('58 ˚55) east To Govater (61°25׳) east in the waters of the Oman Sea (Sistan and Baluchistan province) based on trawl survey results in 2013 by R/V Ferdo...

Phase Calibration Sources in the Northern Sky at Galactic Latitudes

The 6.7-GHz and 25-GHz methanol masers in OMC-1

The Australia Telescope Compact Array (ATCA) has been used to search for methanol maser emission at 6.7 GHz towards OMC-1. Two features peaking at 7.2 km s and −1.1 km s have been detected. The former has at least two components close in both velocity and position. It is located south-east of the Orion Kleinmann-Low (Orion-KL) nebula in the region of outflow traced by the 25-GHz methanol masers...

Parsec-scale properties of GHz-Peaked Spectrum sources from 2.3 and 8.6 GHz VLBI surveys

We investigate the sample of 213 GPS sources selected from simultaneous multi-frequency 1– 22 GHz observations obtained with RATAN–600 radio telescope. We use publicly available data to characterize parsec-scale structure of the selected sources. Among them we found 121 core dominated sources, 76 Compact Symmetric Object (CSO) candidates (24 of them are highly probable), 16 sources have complex...
