Synchrotron emission from the blazar PG 1553+113. An analysis of its flux and polarization variability
C. M. Raiteri, F. Nicastro, A. Stamerra +4
In 2015 July 29 - September 1 the satellite XMM-Newton pointed at the BL Lac object PG 1553+133 six times, collecting data for 218 hours. During one of these epochs, simultaneous o…
A closer look at the "characteristic" width of molecular cloud filaments
G. V. Panopoulou, I. Psaradaki, R. Skalidis +2
Filaments in Herschel molecular cloud images are found to exhibit a "characteristic width". This finding is in tension with spatial power spectra of the data, which show no indicat…
RoboPol: The optical polarization of gamma-ray--loud and gamma-ray--quiet blazars
E. Angelakis, T. Hovatta, D. Blinov +25
We present average R-band optopolarimetric data, as well as variability parameters, from the first and second RoboPol observing season. We investigate whether gamma- ray--loud and…
Optical polarization of high-energy BL Lac objects
T. Hovatta, E. Lindfors, D. Blinov +9
We investigate the optical polarization properties of high-energy BL Lac objects using data from the RoboPol blazar monitoring program and the Nordic Optical Telescope. We wish to…
RoboPol: Do optical polarization rotations occur in all blazars?
D. Blinov, V. Pavlidou, I. Papadakis +23
We present a new set of optical polarization plane rotations in blazars, observed during the third year of operation of RoboPol. The entire set of rotation events discovered during…
The magnetic field and dust filaments in the Polaris Flare
G. V. Panopoulou, I. Psaradaki, K. Tassis
In diffuse molecular clouds, possible precursors of star-forming clouds, the effect of the magnetic field is unclear. In this work we compare the orientations of filamentary struct…
RoboPol: optical polarization-plane rotations and flaring activity in blazars
D. Blinov, V. Pavlidou, I. E. Papadakis +26
We present measurements of rotations of the optical polarization of blazars during the second year of operation of RoboPol, a monitoring programme of an unbiased sample of gamma-ra…
