Self-consistent modeling of energy-dependent synchrotron polarization in blazars with application to Mrk 421
Frederike Apel, Motseothata Tisang, Victor Barbosa Martins +3
Observations of black hole jets closely aligned with our line of sight, known as blazars, have revealed that their X-ray emission can be significantly more polarized than in the op…
Multi-wavelength Behaviour and Lepto-hadronic Modeling of PKS 0215+015 Around the Epoch of IceCube-220225A
Athira M Bharathan, Markus Böttcher
The detection of high-energy astrophysical neutrinos has opened a new avenue for identifying cosmic particle accelerators. Blazars, active galactic nuclei (AGN) with relativistic j…
A Gamma-ray Emitting Head-Tail Radio Galaxy Swimming Through the Hot Medium of the Merging Cluster Abell 3627
Vaidehi S. Paliya, M. Böttcher, Swayamtrupta Panda +4
Head-tail radio sources are jetted active galactic nuclei (AGN) moving through the dense intracluster medium of galaxy clusters. They are extremely rare in the gamma-ray sky, likel…
The broadband spectral energy distribution of candidate neutrino blazars
Athira M Bharathan, C. S. Stalin, Markus Böttcher +3
Blazars, the jet dominated class of AGN comprising flat spectrum radio quasars (FSRQs) and BL Lac objects (BL Lacs) are now increasingly identified as potential sources of high ene…
Investigating polarization signatures from GRB models
Pieter vd Merwe, Markus Böttcher
There is still much debate around the inner workings of the GRB prompt emission phase with many questions still left unanswered. Polarization signatures offer a promising new avenu…
The most distant -ray flare to date: a multiwavelength campaign on the blazar GB6 B1428+4217
Andrea Gokus, Manel Errando, Ivan Agudo +12
In November 2023, the Fermi Large Area Telescope detected a -ray flare from the high-redshift blazar GB6 B1428+4217 (). We initiated a multi-wavelength follow-up campai…
