Modeling the Spectral Energy Distribution and Variability of 3c 66a during the Webt Campaign of 2003y2004
The BL Lac object 3C 66Awas observed in an extensive multiwavelength monitoring campaign (the Whole Earth Blazar Telescope [WEBT] campaign) from2003 July until 2004April. The spectral energy distribution (SED)wasmeasured over the entire electromagnetic spectrum, with flux measurements from radio to X-ray frequencies and upper limits in the very high energy (VHE) -ray regime. Here we use a time-...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
A TeV source in the 3C 66A/B region
The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 hr in 2007 August–December. The observations resulted in the discovery of a γ-ray source centered at celestial coordinates R.A. = 22312 and decl.= 430.7 (MAGIC J0223+430), coinciding with the nearby radio galaxy 3C 66B. A possible association of the excess with the blazar 3C 66A is discussed. The energy spectrum o...

متن کاملThe OJ 287 colors during a multiwavelength campaign
In 2005 the blazar OJ 287 exhibited an interesting variable behavior in the optical band. An optical outburst was observed in the period Oct.-Nov. 2005, and two XMM-Newton X-ray observations were performed in correspondence with two active optical states of the source (an intermediate flare and such claimed outburst). These satellite pointings triggered and invited observations by several radio...
