      More Details Abstract Fulltext PDF

      The infrared properties of Fermi AGNs were investigated using the survey data of the Wide-field Infrared Survey Explorer (WISE). The results showed:

      BL Lacs tend to be brighter than FSRQs at 3.4 𝜇m. However, with increase of wavelength, FSRQs tend to be brighter than BL Lacs.

      FSRQs colours are redder than BL Lacs;

      A strong correlation exists between infrared and 𝛾-ray luminosity.

      More Details Abstract Fulltext PDF

      We present our observations toward Sgr B2 region in 𝐽 = 1−0 lines of 12CO, 13CO, C18O and C17O using 13.7-m Delingha millimeter telescope with newly installed 9-beam SIS superconducting receiver. From the integrated line intensity, we derive the abundance ratio of C18O/C17O with a mean value of 3.11 ± 0.10, which is consistent with the previous results.

    • Continuous Article Publication

      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.
