Exploring the Connection between UV/Optical Variations and Radio Emission in Radio-Quiet Quasars: Clues on Radio Emission Origin
Mai Liao, Junxian Wang, Wenyong Kang +1
The radio emission in radio-quiet quasars (RQQs) has been a long mystery and its physical origin remains unclear. In a previous work we find UV/optical more variable quasars have s…
The X-ray emission in young radio AGNs
Mai Liao, Minfeng Gu, Minhua Zhou +1
In this work, we investigated the X-ray emission for a sample of young radio AGNs by combining their data from Chandra/XMM-Newton and at other wavebands. We find strong correlation…
Investigation on Young radio AGNs based on SDSS spectroscopy
Mai Liao, Minfeng Gu
The Gigahertz Peaked Spectrum (GPS) sources, Compact Steep Spectrum (CSS) radio sources, and High Frequency Peakers (HFP) radio sources are thought to be young radio AGNs, at the e…
Long-term optical spectroscopic variations in blazar 3C 454.3
Krzysztof Nalewajko, Alok C. Gupta, Mai Liao +3
Characterisation of the long-term variations in the broad line region in a luminous blazar, where Comptonisation of broad-line emission within a relativistic jet is the standard sc…
Intra-day variability of three Seyfert Galaxies measured with XMM-Newton
Ashutosh Tripathi, Paul J. Wiita, Alok C. Gupta +2
We present and analyze the variability of three Seyfert galaxies on intra-day timescales. We have analyzed in a uniform manner the 38 longest ( ks) observations made for NGC…
A peculiar multi-wavelength flare in the Blazar 3C 454.3
Alok C. Gupta, Arun Mangalam, Paul J. Wiita +20
The blazar 3C454.3 exhibited a strong flare seen in gamma-rays, X-rays, and optical/NIR bands during 3--12 December 2009. Emission in the V and J bands rose more gradually than did…
