H0LiCOW - IX. Cosmographic analysis of the doubly imaged quasar SDSS 1206+4332 and a new measurement of the Hubble constant
S. Birrer, T. Treu, C. E. Rusu +15
We present a blind time-delay strong lensing (TDSL) cosmographic analysis of the doubly imaged quasar SDSS 1206+4332. We combine the relative time delay between the quasar images,…
COSMOGRAIL XVII: Time delays for the quadruply imaged quasar PG 1115+080
V. Bonvin, J. H. H. Chan, M. Millon +24
We present time-delay estimates for the quadruply imaged quasar PG 1115+080. Our resuls are based on almost daily observations for seven months at the ESO MPIA 2.2m telescope at La…
Constraining the microlensing effect on time delays with new time-delay prediction model in measurements
Geoff C. -F. Chen, James H. H. Chan, Vivien Bonvin +14
Time-delay strong lensing provides a unique way to directly measure the Hubble constant (). The precision of the measurement depends on the uncertainties in the time…
A Search for Gravitationally Lensed Quasars and Quasar Pairs in Pan-STARRS1: Spectroscopy and Sources of Shear in the Diamond 2M11342103
Cristian E. Rusu, Ciprian T. Berghea, Christopher D. Fassnacht +4
We present results of a systematic search for gravitationally lensed quasars in Pan-STARRS1. Our final sample of candidates comprises of 91 systems, not including 25 rediscovered l…
