Abstract:
We present time-delay estimates for the quadruply imaged quasar PG
1115+080. Our results are based on almost daily observations for seven
months at the ESO MPIA 2.2m telescope at La Silla Observatory,
reaching a signal-to-noise ratio of about 1000 per quasar image. In
addition, we re-analyze existing light curves from the literature that
we complete with an additional three seasons of monitoring with the
Mercator telescope at La Palma Observatory. When exploring the
possible source of bias we considered the so-called microlensing time
delay, a potential source of systematic error so far never directly
accounted for in previous time-delay publications. In fifteen years of
data on PG 1115+080, we find no strong evidence of microlensing time
delay. Therefore not accounting for this effect, our time-delay
estimates on the individual data sets are in good agreement with each
other and with the literature.
Description:
We have been monitoring the quadruply lensed quasar PG1115+080 for
8 months in the R band (∼600-720nm) using the MPIA/ESO 2.2m telescope.
The resulting R-band light curves of the quadruply lensed quasar
PG1115+080, is displayed in Fig. 2 of the paper.
