iPTF Survey for Cool Transients
S. M. Adams, N. Blagorodnova, M. M. Kasliwal +25
We performed a wide-area (2000 deg) g and I band experiment as part of a two month extension to the Intermediate Palomar Transient Factory. We discovered 36 extragalactic tra…
A kilonova as the electromagnetic counterpart to a gravitational-wave source
S. J. Smartt, T. -W. Chen, A. Jerkstrand +118
Gravitational waves were discovered with the detection of binary black hole mergers and they should also be detectable from lower mass neutron star mergers. These are predicted to…
Estimating dust distances to Type Ia supernovae from colour excess time-evolution
M. Bulla, A. Goobar, R. Amanullah +2
We present a new technique to infer dust locations towards reddened Type Ia supernovae and to help discriminate between an interstellar and a circumstellar origin for the observed…
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…
No evidence of circumstellar gas surrounding Type Ia Supernova SN 2017cbv
Raphael Ferretti, Rahman Amanullah, Mattia Bulla +3
Nearby type Ia supernovae (SNe Ia), such as SN 2017cbv, are useful events to address the question of what the elusive progenitor systems of the explosions are. Hosseinzadeh et al.…
Testing for redshift evolution of Type Ia supernovae using the strongly lensed PS1-10afx at
T. Petrushevska, R. Amanullah, M. Bulla +4
The light from distant supernovae (SNe) can be magnified through gravitational lensing when a foreground galaxy is located along the line of sight. This line-up allows for detailed…
