The rise and fall of the iron-strong nuclear transient PS16dtm
T. Petrushevska, G. Leloudas, D. Ilic +30
Thanks to the advent of large-scale optical surveys, a diverse set of flares from the nuclear regions of galaxies has recently been discovered. These include the disruption of star…
Gaia Photometric Science Alerts
S. T. Hodgkin, D. L. Harrison, E. Breedt +108
Since July 2014, the Gaia mission has been engaged in a high-spatial-resolution, time-resolved, precise, accurate astrometric, and photometric survey of the entire sky. Aims: We pr…
The complex variability of blazars: Time-scales and periodicity analysis in S4 0954+65
C. M. Raiteri, M. Villata, V. M. Larionov +3
Among active galactic nuclei, blazars show extreme variability properties. We here investigate the case of the BL Lac object S4 0954+65 with data acquired in 2019-2020 by the Trans…
Multi-Wavelength Variability of BL Lacertae Measured with High Time Resolution
Zachary R. Weaver, K. E. Williamson, S. G. Jorstad +54
In an effort to locate the sites of emission at different frequencies and physical processes causing variability in blazar jets, we have obtained high time-resolution observations…
Gaia 18dvy: a new FUor in the Cygnus OB3 association
E. Szegedi-Elek, P. Ábrahám, L. Wyrzykowski +59
We present optical-infrared photometric and spectroscopic observations of Gaia18dvy, located in the Cygnus OB3 association at a distance of 1.88 kpc. The object was noted by the Ga…
Optical Variability of Three Extreme TeV Blazars
Ashwani Pandey, Alok C. Gupta, G. Damljanovic +3
We present the results of optical photometric observations of three extreme TeV blazars, 1ES 0229200, 1ES 0414009, and 1ES 2344514, taken with two telescopes (1.3 m Devast…
