Multimessenger observations of counterparts to IceCube-190331A
Felicia Krauß, Emily Calamari, Azadeh Keivani +9
High-energy neutrinos are a promising tool for identifying astrophysical sources of high and ultra-high energy cosmic rays (UHECR). Prospects of detecting neutrinos at high energie…
Multiwavelength study of potential blazar candidates among Fermi-LAT unidentified gamma-ray sources
Jean Damascène Mbarubucyeye, Felicia Krauß, Pheneas Nkundabakura
Studying unidentified γ-ray sources is important as they may hide new discoveries. We conducted a multiwavelength analysis of 13 unidentified Fermi-LAT sources in the 3FGL catalog…
X-ray spectral and flux variability of the microquasar GRS 1758-258 on timescales from weeks to years
Maria Hirsch, Katja Pottschmidt, David M. Smith +12
We present the spectral and timing evolution of the persistent black hole X-ray binary GRS 1758-258 based on almost 12 years of observations using the Rossi X-ray Timing Explorer P…
Apparent superluminal core expansion and limb brightening in the candidate neutrino blazar TXS 0506+056
E. Ros, M. Kadler, M. Perucho +5
IceCube has reported a very-high-energy neutrino (IceCube-170922A) in a region containing the blazar TXS 0506+056. Correlated γ-ray activity has led to the first high-probability a…
The unique case of the AGN core of M87: a misaligned low power blazar?
Matteo Lucchini, Felicia Krauss, Sera Markoff
M87 hosts one of the closest jetted active galactic nucleus (AGN) to Earth. Thanks to its vicinity and to the large mass of is central black hole, M87 is the only source in which t…
