    • Abstract

       

      We carried out a pilot 1.3-cm IDV observations of two dozens of AGNs at Urumqi from 23 to 25 November 2011. Six sources, namely J0136+4751, J0217+0144, J1058+0133, J1751+0939, J1833−2103 and DA193 were detected as IDV sources at a 99% confidence level (about 3𝜎 level). The weather was fine during the observation period, but the system noise after calibration remained which could be due to the data sampled are relatively sparse for each source in the observations.

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
