PublicationLarge-amplitude Prominence Oscillations following Impact by a Coronal Jet
Observational evidence shows that coronal jets can hit prominences and set them in motion. The impact leads to large-amplitude oscillations (LAOs) in the...

PublicationLeMMINGs III. The e-MERLIN legacy survey of the Palomar sample: exploring the origin of nuclear radio emission in active and inactive galaxies through the [O III] - radio connection
What determines the nuclear radio emission in local galaxies? To address this question, we combine optical [O III] line emission, robust black hole (BH) mass...

PublicationLong-term multi-wavelength study of 1ES 0647+250
Context. The BL Lac object 1ES 0647+250 is one of the few distant γ-ray emitting blazars detected at very high energies (VHEs; ≳100 GeV) during a non-flaring...

PublicationLow optical polarization at the core of the optically thin jet of M87
We study the optical linear and circular polarization in the optically thin regime of the core and jet of M87. Observations were acquired two days before the...

PublicationMAGIC detection of short-term variability of the high-peaked BL Lac object 1ES 0806+524
The high-frequency-peaked BL Lac (HBL) 1ES 0806+524 (z = 0.138) was discovered in very high energy (VHE) γ-rays in 2008. Until now, the broad-band spectrum of...

PublicationMAGIC detection of sub-TEV emission from gravitationally lensed blazar QSO B0218+357
The blazar QSO B0218+357 is the first gravitationally lensed blazar detected in the very high energy (VHE, E > 100 GeV) gamma-ray spectral range (Ahnen et al...
