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…
iPTF16geu: A multiply imaged, gravitationally lensed type Ia supernova
A. Goobar, R. Amanullah, S. R. Kulkarni +31
We report the discovery of a multiply-imaged gravitationally lensed Type Ia supernova, iPTF16geu (SN 2016geu), at redshift . This phenomenon could be identified because th…
The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Quasar Target Selection
Adam D. Myers, Nathalie Palanque-Delabrouille, Abhishek Prakash +34
As part of the Sloan Digital Sky Survey IV the extended Baryon Oscillation Spectroscopic Survey (eBOSS) will improve measurements of the cosmological distance scale by applying the…
Discovery of a Cosmological, Relativistic Outburst via its Rapidly Fading Optical Emission
S. Bradley Cenko, S. R. Kulkarni, Assaf Horesh +26
We report the discovery by the Palomar Transient Factory (PTF) of the transient source PTF11agg, which is distinguished by three primary characteristics: (1) bright, rapidly fading…
Type Ia Supernovae Strongly Interacting with Their Circumstellar Medium
Jeffrey M. Silverman, Peter E. Nugent, Avishay Gal-Yam +31
Owing to their utility for measurements of cosmic acceleration, Type Ia supernovae (SNe) are perhaps the best-studied class of SNe, yet the progenitor systems of these explosions l…
Sensitive Search For Radio Variables And Transients In The Extended Chandra Deep-Field South
K. P. Mooley, D. A. Frail, E. O. Ofek +3
We report on an analysis of the Extended Chandra Deep Field South (E-CDFS) region using archival data from the Very Large Array, with the goal of studying radio variability and tra…
