What Color is the Sky (for a non-human) ?
Yair Weiss, Ofer Springer
The light of the daytime sky contains a mixture of many colors yet is perceived as blue by human observers. This is largely due to the particular response functions of the human co…
TRANSLIENT: Detecting Transients Resulting from Point Source Motion or Astrometric Errors
O. Springer, E. O. Ofek, B. Zackay +10
Detection of moving sources over complicated background is important for several reasons. First is measuring the astrophysical motion of the source. Second is that such motion resu…
Measuring time delays: II. Using observations of the unresolved flux and astrometry
Ofer M. Springer, Eran O. Ofek
Lensed quasars and supernovae can be used to study galaxies' gravitational potential and measure cosmological parameters. The typical image separation of objects lensed by galaxies…
Measuring time delays: I. Using a flux time series that is a linear combination of time-shifted light curves
Ofer M. Springer, Eran O. Ofek
(Abridged) Several phenomena in astrophysics generate light curves with time delays. Among these are reverberation mapping, and lensed quasars. In some systems, the measurement of…
Weak lensing shear estimation beyond the shape-noise limit: a machine learning approach
Ofer M. Springer, Eran O. Ofek, Yair Weiss +1
Weak lensing shear estimation typically results in per galaxy statistical errors significantly larger than the sought after gravitational signal of only a few percent. These statis…
Reflection Separation Using Guided Annotation
Ofer Springer, Yair Weiss
Photographs taken through a glass surface often contain an approximately linear superposition of reflected and transmitted layers. Decomposing an image into these layers is general…
Asteroseismic effects in close binary stars
Ofer M. Springer, Nir J. Shaviv
Turbulent processes in the convective envelopes of the sun and stars have been shown to be a source of internal acoustic excitations. In single stars, acoustic waves having frequen…
