    • Assigning degrees of stochasticity to blazar light curves in the radio band using complex networks 
      Acosta Tripailao, Belén; Max-Moerbeck Astudillo, Walter Kennerth; Pastén Guzmán, Denisse Elizabeth del Carmen; Moya Fuentes, Pablo Sebastián (MDPI, 2022)
      We focus on characterizing the high-energy emission mechanisms of blazars by analyzing the variability in the radio band of the light curves of more than a thousand sources. We are interested in assigning complexity ...
    • Characterization of the variability of blazars in the radio band 
      Navarro Aránguiz, Víctor Alberto (Universidad de Chile, 2023)
      Los blazares son un tipo de galaxia de núcleo activo con jets relativistas orientados muy cercano a la línea de visión entre el objeto y el observador. Estos objetos emiten radiación sobre todo el espectro electromagnético, ...
    • From solar wind to blazars: analyzing time series with horizontal visibility graphs 
      Acosta Azócar, Belén Ayleen (Universidad de Chile, 2022)
      In the case of astronomical observations, it is useful to work with new methods that are effective to complement the characterization of systems for which only limi ted information is available. The generality of the ...
    • Multiwavelength variability power spectrum analysis of the blazars 3C 279 and PKS 1510–089 on multiple timescales 
      Goyal, Arti; Soida, Marian; Stawarz, Lukasz; Wiita, Paul J.; Nilsson, Kari; Jorstad, Svetlana; Marscher, Alan P.; Aller, Margo F.; Aller, Hugh D.; Lähteenmäki, Anne; Hovatta, Talvikki; Zoła, Staszek; Nalewajko, Krzysztof; Tornikoski, Merja; Tammi, Joni; Hodges, Mark; Kiehlmann, Sebastian; Readhead, Anthony C. S.; Max-Moerbeck Astudillo, Walter Kennerth; Lindfors, Elina; Ramazani, Vandad Fallah; Reichart, D. E.; Caton, D. B.; Valverde, Janeth; Horan, Deirdre; Ojha, Roopesh; Van Zyl, Pfesesani (IOP, 2022)
      We present the results of variability power spectral density (PSD) analysis using multiwavelength radio to GeV gamma-ray light curves covering timescales of decades/years to days/minutes for the blazars 3C 279 and PKS ...
    • Optical spectroscopy of blazars for the Cherenkov Telescope Array 
      Goldoni, P.; Pita, S.; Boisson, C.; Max-Moerbeck Astudillo, Walter Kennerth; Kasai, E.; Williams, D. A.; D’Ammando, F.; Navarro Aránguiz, Víctor Alberto; Backes, M.; Barres de Almeida, U.; Becerra González, J.; Cotter, G.; Hervet, O.; Lenain, J. P.; Lindfors, E.; Sol, H.; Wagner, S. (Elsevier, 2021)
      Context. Blazars are the most numerous class of high-energy (HE; E similar to 50 MeV-100 GeV) and very high-energy (VHE; E similar to 100 GeV-10 TeV) gamma-ray emitters. Currently, a measured spectroscopic redshift is ...
