Feasibility of ultra-high-energy cosmic ray backtracking through sparse local measurements of the Galactic magnetic field
S. Romanopoulos, M. Mastorakis, V. Pavlidou
Planned and ongoing campaigns for the acquisition of high-quality local measurements of the Galactic magnetic field (GMF) at interstellar cloud locations have generated intense int…
GRB 210619B optical afterglow polarization
N. Mandarakas, D. Blinov, D. R. Aguilera-Dena +7
We report on the follow-up of the extremely bright long gamma-ray burst GRB~210619B with optical polarimetry. We conducted optopolarimetric observations of the optical afterglow of…
Deflections of ultra-high energy cosmic rays by the Milky Way magnetic field: how well can they be corrected?
G. Magkos, V. Pavlidou
Locating the sources of ultra-high energy cosmic rays (UHECRs) still remains a difficult puzzle for modern astrophysics. A major hurdle in the search for the sources is the fact th…
The dependence of optical polarisation of blazars on the synchrotron component peak frequency
Emmanouil Angelakis, Dmitry Blinov, Markus Böttcher +5
The RoboPol instrument and the relevant program was developed in order to conduct a systematic study of the optical polarisation variability of blazars. Driven by the discovery tha…
Robopol: Optical polarisation monitoring of blazars
Emmanouil Angelakis, Dmitry Blinov, Markus Böttcher +5
The RoboPol program has been monitoring the -band linear polarisation parameters of an unbiased sample of 60 gamma-ray-loud blazars and a "control" sample of 15 gamma-ray-quite…
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…
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…
Estimating the distribution of rest-frame timescales for blazar jets: a statistical approach
I. Liodakis, D. Blinov, I. Papadakis +1
In any flux-density limited sample of blazars, the distribution of the timescale modulation factor , which quantifies the change in observed timescales compared to the rest…
Early-time polarized optical light curve of GRB 131030A
O. G. King, D. Blinov, D. Giannios +23
We report the polarized optical light curve of a gamma-ray burst afterglow obtained using the RoboPol instrument. Observations began 655 seconds after the initial burst of gamma-ra…
MAGIC long-term study of the distant TeV blazar PKS 1424+240 in a multiwavelength context
MAGIC Collaboration, J. Aleksić, S. Ansoldi +168
We present a study of the very high energy (VHE; E > 100 GeV) gamma-ray emission of the blazar PKS 1424+240 observed with the MAGIC telescopes. The primary aim of this paper is the…
