The Palomar Transient Factory Core-Collapse Supernova Host-Galaxy Sample. I. Host-Galaxy Distribution Functions and Environment-Dependence of CCSNe
Steve Schulze, Ofer Yaron, Jesper Sollerman +51
Several thousand core-collapse supernovae (CCSNe) of different flavors have been discovered so far. However, identifying their progenitors has remained an outstanding open question…
Spectroscopy of the first resolved strongly lensed Type Ia supernova iPTF16geu
J. Johansson, A. Goobar, S. H. Price +14
We report the results from spectroscopic observations of the multiple images of the strongly lensed Type Ia supernova (SN Ia), iPTF16geu, obtained with ground based telescopes and…
ZTF Early Observations of Type Ia Supernovae III: Early-Time Colors as a Test for Explosion Models and Multiple Populations
Mattia Bulla, Adam A. Miller, Yuhan Yao +22
Colors of Type Ia supernovae in the first few days after explosion provide a potential discriminant between different models. In this paper, we present colors of 65 Type Ia s…
Type IIn supernova light-curve properties measured from an untargeted survey sample
A. Nyholm, J. Sollerman, L. Tartaglia +19
We present a sample of supernovae Type IIn (SNe IIn) from the untargeted, magnitude-limited surveys of the Palomar Transient Factory (PTF) and its successor, the intermediate PTF (…
Characterising the secondary maximum in the r-band for Type Ia Supernovae: Diagnostic for the ejecta mass
Seméli Papadogiannakis, Suhail Dhawan, Roberta Morosin +1
An increase in the number of studied Type Ia supernovae (SNe~Ia) has demonstrated that this class of explosions has a greater diversity in its observables than was previously assum…
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…
iPTF16abc and the population of Type Ia supernovae: Comparing the photospheric, transitional and nebular phases
S. Dhawan, M. Bulla, A. Goobar +6
Key information about the progenitor system and the explosion mechanism of Type Ia supernovae (SNe~Ia) can be obtained from early observations, within a few days from explosion. iP…
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…
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…
SN2002es-like Supernovae From Different Viewing Angles
Yi Cao, S. R. Kulkarni, Avishay Gal-Yam +4
In this letter, we compare optical light curves of two SN2002es-like Type Ia supernovae, iPTF14atg and iPTF14dpk, from the intermediate Palomar Transient Factory. Although the two…
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)…
The rise of SN2014J in the nearby galaxy M82
A. Goobar, J. Johansson, R. Amanullah +31
We report on the discovery of SN2014J in the nearby galaxy M82. Given its proximity, it offers the best opportunity to date to study a thermonuclear supernova over a wide range of…
The Effect of Probe Dynamics on Galactic Exploration Timescales
Duncan H. Forgan, Semeli Papadogiannakis, Thomas Kitching
The travel time required for one civilisation to explore the Milky Way using probes is a crucial component of Fermi's Paradox. Previous attempts to estimate this travel time have a…
