Microlensing analysis of 14.5-year light curves in SDSS J1004+4112: Quasar accretion disk size and intracluster stellar mass fraction

Open Access

Table 1.

Inferred stellar mass fraction and convergence in stars at the locations of the four quasar images.

Image	α	κ_*	d (kpc/h)
A	> 0.059	> 0.042	42.1 ± 0.2
B	$0 . 056_{- 0.027}^{+ 0.021}$ $0.056^{+0.021}_{-0.027}$	$0 . 036_{- 0.018}^{+ 0.014}$ $0.036^{+0.014}_{-0.018}$	42.7 ± 0.2
C	$0 . 030_{- 0.021}^{+ 0.031}$ $0.030^{+0.031}_{-0.021}$	$0 . 018_{- 0.012}^{+ 0.018}$ $0.018^{+0.018}_{-0.012}$	49.0 ± 0.2
D	$0 . 072_{- 0.016}^{+ 0.034}$ $0.072^{+0.034}_{-0.016}$	$0 . 073_{- 0.016}^{+ 0.035}$ $0.073^{+0.035}_{-0.016}$	27.5 ± 0.2

Notes. Lensed quasar images are labelled from A to D, α is the stellar mass fraction, κ_* is the convergence in stars, and d is the distance from each quasar image to the BCG.
