Prospects for observing strongly lensed supernovae behind Hubble Frontier Fields galaxy clusters with the James Webb Space Telescope
T. Petrushevska, T. Okamura, R. Kawamata +3
Measuring time delays from strongly lensed supernovae (SNe) is emerging as a novel and independent tool for estimating the Hubble constant . This is very important given the…
R-band light-curve properties of Type Ia supernovae from the (intermediate) Palomar Transient Factory
S. Papadogiannakis, A. Goobar, R. Amanullah +15
We present the best 265 sampled R-band light curves of spectroscopically identified Type Ia supernovae (SNe) from the Palomar Transient Factory (PTF; 2009-2012) survey and the inte…
Searching for supernovae in the multiply-imaged galaxies behind the gravitational telescope A370
T. Petrushevska, A. Goobar, D. J. Lagattuta +7
Strong lensing by massive galaxy clusters can provide magnification of the flux and even multiple images of the galaxies that lie behind them. This phenomenon facilitates observati…
Probing gas and dust in the tidal tail of NGC 5221 with the type Ia supernova iPTF16abc
R. Ferretti, R. Amanullah, A. Goobar +8
Context. Type Ia supernovae (SNe Ia) can be used to address numerous questions in astrophysics and cosmology. Due to their well known spectral and photometric properties, SNe Ia ar…
Two New Calcium-Rich Gap Transients in Group and Cluster Environments
R. Lunnan, M. M. Kasliwal, Y. Cao +20
We present the Palomar Transient Factory discoveries and the photometric and spectroscopic observations of PTF11kmb and PTF12bho. We show that both transients have properties consi…
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…
Diversity in extinction laws of Type Ia supernovae measured between and
R. Amanullah, J. Johansson, A. Goobar +36
We present ultraviolet (UV) observations of six nearby Type~Ia supernovae (SNe~Ia) obtained with the Hubble Space Telescope, three of which were also observed in the near-IR (NIR)…
