Profound optical flares from the relativistic jets of active galactic nuclei
Gopal Bhatta, Staszek Zola, M. Drozdz +11
Intense outbursts in blazars are among the most extreme phenomena seen in extragalactic objects. Studying these events can offer important information about the energetic physical…
Catching profound optical flares in blazars
Gopal Bhatta, Staszek Zola, M. Drozdz +11
Flaring episodes in blazars represent one of the most violent processes observed in extra-galactic objects. Studies of such events shed light on the energetics of the physical proc…
Rapid X-ray Variability in Mkn 421 during a Multiwavelength Campaign
Alex G. Markowitz, Krzysztof Nalewajko, Gopal Bhatta +47
The study of short-term variability properties in AGN jets has the potential to shed light on their particle acceleration and emission mechanisms. We report results from a four-day…
Characterising the extended morphologies of BL Lacs at 144 MHz with LOFAR
Seán Mooney, Francesco Massaro, John Quinn +11
We present a morphological and spectral study of a sample of 99 BL Lacs using the LOFAR Two-Metre Sky Survey Second Data Release (LDR2). Extended emission has been identified at gi…
Complex Structure of the Eastern Lobe of the Pictor A Radio Galaxy: Spectral Analysis and X-ray/Radio Correlations
R. Thimmappa, Ł. Stawarz, U. Pajdosz-Śmierciak +2
Here we present detailed analysis of the distinct X-ray emission features present within the Eastern radio lobe of the Pictor A galaxy, around the jet termination region, utilising…
X-ray, UV and optical time delays in the bright Seyfert galaxy Ark 120 with co-ordinated Swift and ground-based observations
A. P. Lobban, S. Zola, U. Pajdosz-Smierciak +17
We report on the results of a multiwavelength monitoring campaign of the bright, nearby Seyfert galaxy, Ark 120 using a ~50-day observing programme with Swift and a ~4-month co-ord…
