The broad-line type Ic SN 2020bvc: signatures of an off-axis gamma-ray burst afterglow
L. Izzo, K. Auchettl, J. Hjorth +5
Long-duration gamma-ray bursts (GRBs) are almost unequivocally associated with very energetic, broad-lined supernovae (SNe) of Type Ic-BL. While the gamma-ray emission is emitted i…
Dynamical friction-driven orbital circularisation in rotating discs: a semi-analytical description
Matteo Bonetti, Elisa Bortolas, Alessandro Lupi +2
We present and validate a novel semi-analytical approach to study the effect of dynamical friction on the orbits of massive perturbers in rotating stellar discs. We find that dynam…
Modelling the AGN broad line region using single-epoch spectra II. Nearby AGN
S. I. Raimundo, M. Vestergaard, M. R. Goad +4
The structure of the broad line region (BLR) is an essential ingredient in the determination of active galactic nuclei (AGN) virial black hole masses, which in turn are important t…
Modelling the AGN broad line region using single-epoch spectra I. The test case of Arp 151
S. I. Raimundo, A. Pancoast, M. Vestergaard +2
We show that individual (single-epoch) spectra of AGN can constrain some of the geometry and dynamics of the AGN broad line region. Studies of the cosmic influence of supermassive…
A nuclear molecular outflow in the Seyfert galaxy NGC3227
A. Alonso-Herrero, S. Garcia-Burillo, M. Pereira-Santaella +24
We present ALMA observations of the CO(2-1) and CO(3-2) molecular gas transitions and associated (sub)-mm continua of the nearby Seyfert 1.5 galaxy NGC3227 with angular resolutions…
MUSE observations of a changing-look AGN I: The re-appearance of the broad emission lines
S. I. Raimundo, M. Vestergaard, J. Y. Koay +3
Optical changing-look Active Galactic Nuclei (AGN) are a class of sources that change type within a short timescale of years or decades. This change is characterised by the appeara…
