Near-infrared micro-variability of radio-loud quasars
نویسندگان
چکیده
We observed three AGN from the Parkes Half-Jansky Flat-spectrum Sample at nearinfrared (NIR) wavelengths to search for micro-variability. In one source, the blue quasar PKS 2243−123, good evidence for NIR micro-variability was found. In the other two sources, PKS 2240−260 and PKS 2233−148, both BL Lacertae objects, no such evidence of variability was detected. We discuss the implications of these observations for the various mechanisms that have been proposed for micro-variability.

متن کاملVariability of Quasars at 10 Microns1 G. Neugebauer and K. Matthews
Twenty-Ðve low-redshift quasars have been monitored for several decades at Ðve nearand midinfrared wavelengths to detect rapid variations that would indicate that a nonthermal component was present in the ““ 10 km bump.ÏÏ Such variability has apparently been detected in several radio-loud quasars and in the radio-quiet quasar PG 1535]547. In addition, the structure function of PG 1226]023 shows...
متن کاملImaging Photometry of Seyfert 1 AGNs and Quasars III: Variability of Radio Quiet and Radio Loud AGNs
Variability of 226 AGNs in the near-infrared J , H , and K ′ bands is analyzed and discussed. An ensemble average for measured variabilities was obtained for various samples of the AGNs divided by absolute B-magnitude MB, redshift z, and radio strength. All the samples in the J , H , and K ′ bands are found to give significant ensemble variability, but no significant wavelength dependence is fo...
متن کاملNear - infrared imaging of the host galaxies of three radio – loud quasars at z ∼ 1
We present high spatial resolution near–infrared H-band (1.65 μm) images, taken with ISAAC on UT1 of ESO VLT, of three radio-loud quasars at z∼1.5, as a pilot study for imaging of a larger sample of radio-loud and radio-quiet quasars in the redshift range 1 < z < 2. We are able to clearly detect the host galaxy in two quasars (PKS 0000-177 and PKS 0348-120) and marginally in the third (PKS 0402...
