Proximity Operators for Phase Retrieval
Ferréol Soulez, Éric Thiébaut, Antony Schutz +3
We present a new formulation of a family of proximity operators that generalize the projector step for phase retrieval. These proximity operators for noisy intensity measurements c…
Toward an internally consistent astronomical distance scale
Richard de Grijs, Frederic Courbin, Clara E. Martinez-Vazquez +3
Accurate astronomical distance determination is crucial for all fields in astrophysics, from Galactic to cosmological scales. Despite, or perhaps because of, significant efforts to…
An optical time delay for the double gravitational lens system FBQ 0951+2635
P. Jakobsson, J. Hjorth, I. Burud +3
We present optical R-band light curves of the double gravitationally lensed quasar FBQ 0951+2635 from observations obtained at the Nordic Optical Telescope between March 1999 and J…
A quadruply imaged quasar with an optical Einstein ring candidate: 1RXS J113155.4-123155
D. Sluse, J. Surdej, J. -F. Claeskens +6
We report the discovery of a new quadruply imaged quasar surrounded by an optical Einstein ring candidate. Spectra of the different components of 1RXS J113155.4-123155 reveal a sou…
