Context. Short timescale flux density variations in flat spectrum radio sources are often explained by the scattering of radio waves in the turbulent ionized interstellar medium of the Milky Way. One of the most convincing observational arguments in favor of this is the annual modulation of the variability timescale caused by the orbital motion of Earth around the Sun. J1128+5925 is a recently discovered IDV source with a possible annual modulation in its variability timescale. New observations… Expand
High resolution studies of the IDV quasar J1128+592
J1128+592 is a compact radio quasar and, as ~ 30% of flat spectrum radio sources, shows fast variations in the cm-wavelength regime on time-scales of an hour to few days. Such phenomenon is oftenExpand
Radio observations of the first three-month Fermi-AGN at 4.8 GHz
Using the Urumqi 25m radio telescope, sources from the first three-month Fermi-LAT detected AGN catalog with declination >0 were observed in 2009 at 4.8 GHz. The radio flux density appears toExpand
Interstellar scintillation of an extreme scintillator: PKS B1144−379
The University of Tasmania Ceduna radio telescope has been used to investigate rapid variability in the radio flux density of the BL Lac object PKS B1144-379 at 6.7 GHz. High-cadence monitoring ofExpand
Multi-Wavelength Intra-Day Variability and Quasi-Periodic Oscillation in Blazars
We reviewed multi-wavelength blazars variability and detection of quasi-periodic oscillations on intra-day timescales. The variability timescale from a few minutes to up to less than a days isExpand
Intra-day variability observations and the VLBI structure analysis of quasar S4 0917+624
The IDV observations of S4 0917+624 were carried out monthly, from August 2005 to January 2010, with the Urumqi 25m radio telescope at 4.8 GHz. The quasar S4 0917+624 exhibits only very weak or noExpand
Intra-Day Variability Observations of Two Dozens of Blazars at 4.8 GHz
Two dozens of radio loud active galactic nuclei (AGNs) have been observed with Urumqi 25 m radio telescope in order to search for intra-day variability (IDV). The target sources are blazars (namelyExpand

Aims. We aim to search for evidence of annual modulation in the time scales of the BL Lac object S5 0716+714.


J1128+592: a highly variable IDV source
Short time-scale radio variations of compact extragalactic radio quasars and blazars known as IntraDay Variability (IDV) can be explained in at least some sources as a propagation effect; theExpand
Intraday Variability in Northern Hemisphere Radio Sources
Abstract We summarise results from flux density monitoring campaigns performed with the 100 m radio telescope at Effelsberg and the VLA during the past 15 yrs. We briefly discuss some of theExpand
The IDV source J 1128+5925, a new candidate for annual modulation?
Context. Short time-scale radio variations of compact extragalactic radio sources, known as IntraDay Variability (IDV), can be explained in at least some sources by a source-extrinsic effect, inExpand
Very recently, J 1128+5925 was found to show a strong intraday variability at radio wavelengths and might be a new source with the annual modulation of the timescale of its radio variability.Expand
Intra-day variability and the interstellar medium towards 0917+624
The intra-day variable source 0917+624 displays annual changes in its timescale of variability. This is explained in terms of a scintillation model in which changes in the variability timescale areExpand
Annual modulation in the scattering of J1819+3845: Peculiar plasma velocity and anisotropy
We present two years of monitoring observations of the extremely variable quasar J1819+3845. We observe large yearly changes in the timescale of the variations (from ∼1 hour to ∼10 hours at 5 GHz).Expand
Annual Modulation in the Intraday Variability of Quasar 0917+624 due to Interstellar Scintillation
The quasar 0917+624 has been one of the best-studied intraday variable radio sources. However, debate continues as to whether the underlying cause is intrinsic or extrinsic. Much previous work hasExpand
Rapid variability of extragalactic radio sources
Thirty-one extragalactic radio sources have been observed at 2-4 hr intervals for 3-4 days at each of three epochs. The 15 compact sources in the sample appear to display two types of variability.Expand
Optical Variability of the Radio Source J 1128+5925 -- II. Confirmation of its Optical Quietness
The source J 1128+5925 was found recently to show strong intraday variability at radio wavelengths and its radio variability may come from interstellar scintillation. In optical, the object was quietExpand
