Geometry and kinematics of the broad emission line region in the lensed quasar Q2237+0305
Damien Hutsemékers, Dominique Sluse
Line profile distortions are commonly observed in gravitationally lensed quasar spectra. These distortions are caused by microlensing from the stars in the lensing galaxy, which pr…
FeI and NiI in cometary atmospheres. Connections between the NiI/FeI abundance ratio and chemical characteristics of Jupiter-family and Oort-cloud comets
Damien Hutsemékers, Jean Manfroid, Emmanuel Jehin +2
FeI and NiI emission lines have recently been found in the spectra of 17 Solar System comets observed at heliocentric distances between 0.68 and 3.25 au and in the interstellar com…
The similarity of the interstellar comet 2I/Borisov to solar system comets from high resolution optical spectroscopy
C. Opitom, E. Jehin, D. Hutsemékers +11
2I/Borisov - hereafter 2I - is the first visibly active interstellar comet observed in the solar system, allowing us for the first time to sample the composition of a building bloc…
Multiplicity of Galactic Luminous Blue Variable stars
L. Mahy, C. Lanthermann, D. Hutsemékers +7
Context. Luminous Blue Variables (LBVs) are thought to be in a transitory phase between O stars on the main-sequence and the Wolf-Rayet stage. Recent studies suggest that they migh…
A physico-chemical model to study the ion densitydistribution in the inner coma of comet C/2016 R2(Pan-STARRS)
Susarla Raghuram, Anil Bhardwaj, Damien Hutsemékers +3
The recent observations show that comet C/2016 R2 (Pan-Starrs) has a unique and peculiar composition when compared with several other comets observed at 2.8 au heliocentric distanc…
Spectropolarimetry of the changing-look active galactic nucleus Mrk 1018
Damien Hutsemékers, Beatriz Agís González, Frédéric Marin +1
We have obtained new spectropolarimetric observations at visible wavelengths of the changing-look active galactic nucleus (AGN) Mrk 1018. The AGN direct spectrum shows an extremely…
