Multi-Band Intra-Night Optical Variability of BL Lacertae
Haritma Gaur, Alok C. Gupta, R. Bachev +5
We monitored BL Lacertae frequently during 2014 - 2016 when it was generally in a high state. We searched for intra-day variability for 43 nights using quasi-simultaneous measureme…
The Hard X-ray emission of the blazar PKS 2155--304
Haritma Gaur, Liang Chen, R. Misra +4
The synchrotron peak of the X-ray bright High Energy Peaked Blazar (HBL) PKS 2155304 occurs in the UV-EUV region and hence its X-ray emission (0.6--10 keV) lies mostly in the fa…
Signature of Inverse Compton emission from blazars
Haritma Gaur, P. Mohan, Alicja Wierzcholska +1
Blazars are classified into high, intermediate and low energy peaked sources based on the location of their synchrotron peak. This lies in infra-red/optical to ultra-violet bands f…
Multi-wavelength temporal and spectral variability of the blazar OJ 287 during and after the December 2015 flare: a major accretion disc contribution
P. Kushwaha, A. C. Gupta, P. J. Wiita +33
We present a multi-wavelength spectral and temporal analysis of the blazar OJ 287 during its recent activity between December 2015 -- May 2016, showing strong variability in the ne…
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…
White Paper on East Asian Vision for mm/submm VLBI: Toward Black Hole Astrophysics down to Angular Resolution of 1~R
K. Asada, M. Kino, M. Honma +35
This White Paper details the intentions and plans of the East Asian Very Long Baseline Interferometry (VLBI) community for pushing the frontiers of millimeter/submillimeter VLBI. T…
