Constraining the geometry and kinematics of the quasar broad emission line region using gravitational microlensing. II. Comparing models with observations in the lensed quasar HE0435-1223
D. Hutsemékers, L. Braibant, D. Sluse +1
The quadruply lensed quasar HE0435-1223 shows a clear microlensing effect that affects differently the blue and red wings of the H line profile in its image D. To interpret thes…
New constraints on quasar broad absorption and emission line regions from gravitational microlensing
Damien Hutsemékers, Lorraine Braibant, Dominique Sluse +2
Gravitational microlensing is a powerful tool allowing one to probe the structure of quasars on sub-parsec scale. We report recent results, focusing on the broad absorption and emi…
Constraining the geometry and kinematics of the quasar broad emission line region using gravitational microlensing. I. Models and simulations
L. Braibant, D. Hutsemékers, D. Sluse +1
Recent studies have shown that line profile distortions are commonly observed in gravitationally lensed quasar spectra. We investigate the effect of gravitational microlensing on q…
The different origins of high- and low-ionization broad emission lines revealed by gravitational microlensing in the Einstein cross
Lorraine Braibant, Damien Hutsemékers, Dominique Sluse +1
We investigate the kinematics and ionization structure of the broad emission line region of the gravitationally lensed quasar QSO2237+0305 (the Einstein cross) using differential m…
Polarization microlensing in the quadruply imaged broad absorption line quasar H1413+117
D. Hutsemékers, D. Sluse, L. Braibant +1
We have obtained spectropolarimetric observations of the four images of the gravitationally lensed broad absorption line quasar H1413+117. The polarization of the microlensed image…
Evidence for two spatially separated UV continuum emitting regions in the Cloverleaf broad absorption line quasar
D. Sluse, D. Hutsemékers, T. Anguita +2
Testing the standard Shakura-Sunyaev model of accretion is a challenging task because the central region of quasars where accretion takes place is unresolved with telescopes. The a…
