Multiband optical variability on diverse timescales of the blazar Ton 599 from 2011 to 2023
O. Vince, C. M. Raiteri, M. Villata +72
(Shortened)Context: We analyze the optical variability of the FSRQ Ton 599 using BVRI photometry from the WEBT collaboration (2011-2023), complemented by photometric and spectrosco…
Polarimetric and spectropolarimetric observations with FoReRo2: Instrument overview and standard star monitoring
Yanko Nikolov, Galin Borisov, Stefano Bagnulo +3
In this paper, we present a description and characterisation of the 2-Channel Focal Reducer Rozhen (FoReRo2), with an emphasis on its polarimetric and spectropolarimetric observati…
Evolutionary Processes in the Centaur Region
Rosita Kokotanekova, Aurélie Guilbert-Lepoutre, Matthew M. Knight +1
Centaurs populate relatively short-lived and rapidly evolving orbits in the giant-planet region and are believed to be one of the solar system's most complex and diverse population…
Tracing the high-z cosmic web with Quaia: catalogues of voids and clusters in the quasar distribution
Nestor Arsenov, Andras Kovacs, Mar Perez Sar +5
Understanding the formation and evolution of the cosmic web of galaxies is a fundamental goal of cosmology, using various tracers of the cosmic large-scale structure at an ever wid…
Multi-Instrument Observations and Tracking of a Coronal Mass Ejection Front From Low to Middle Corona
Oleg Stepanyuk, Kamen Kozarev
The shape and dynamics of coronal mass ejections (CMEs) vary significantly based on the instrument and wavelength used. This has led to significant debate about the proper definiti…
Type II radio bursts and space weather phenomena: A statistical study
Pooja Devi, Rositsa Miteva, Ramesh Chandra +2
In this paper, we present for the first time a comprehensive statistical study between type II radio bursts from the metric (m) to the dekameric-hectometric (DH) domain and their a…
Multi-wavelength variability analysis of the blazar S5 0716+714 during a long-lasting period of low activity
B. M. Mihov, E. G. Elhosseiny, L. S. Slavcheva-Mihova +3
We conducted a multi-wavelength monitoring campaign of the blazar S5 0716+714 from 2022 November 26 to 2023 May 28 using optical telescopes in Egypt and Bulgaria. Data were taken d…
Determining the origin of the X-ray emission in blazars through multiwavelength polarization
Ioannis Liodakis, Haocheng Zhang, Stella Boula +48
The origin of the high-energy emission in astrophysical jets from black holes is a highly debated issue. This is particularly true for jets from supermassive black holes that are a…
Source location and evolution of a multi-lane type II radio burst
P. Zucca, P. Zhang, K. Kozarev +8
Shocks in the solar corona can accelerate electrons that in turn generate radio emission known as type II radio bursts. The characteristics and morphology of these radio bursts in…
