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…
High-redshift supernova rates measured with the gravitational telescope A1689
Tanja Petrushevska, Rahman Amanullah, Ariel Goobar +12
We present a ground-based near-infrared search for lensed supernovae behind the massive cluster Abell 1689 at z=0.18, one of the most powerful gravitational telescopes that nature…
Time-Varying Sodium Absorption in the Type Ia Supernova 2013gh
R. Ferretti, R. Amanullah, A. Goobar +18
Temporal variability of narrow absorption lines in high-resolution spectra of Type Ia supernovae (SNe Ia) is studied to search for circumstellar matter. Time series which resolve t…
iPTF Search for an Optical Counterpart to Gravitational Wave Trigger GW150914
M. M. Kasliwal, S. B. Cenko, L. P. Singer +28
The intermediate Palomar Transient Factory (iPTF) autonomously responded to and promptly tiled the error region of the first gravitational wave event GW150914 to search for an opti…
