SN 2009N: Linking normal and subluminous type II-P SNe
K. Takáts, M. L. Pumo, N. Elias-Rosa +31
We present ultraviolet, optical, near-infrared photometry and spectroscopy of SN 2009N in NGC 4487. This object is a type II-P supernova with spectra resembling those of subluminou…
The superluminous supernova PS1-11ap: bridging the gap between low and high redshift
M. McCrum, S. J. Smartt, R. Kotak +37
We present optical photometric and spectroscopic coverage of the superluminous supernova (SLSN) PS1-11ap, discovered with the Pan-STARRS1 Medium Deep Survey at z = 0.524. This intr…
Slowly fading super-luminous supernovae that are not pair-instability explosions
M. Nicholl, S. J. Smartt, A. Jerkstrand +57
Super-luminous supernovae that radiate more than 10^44 ergs per second at their peak luminosity have recently been discovered in faint galaxies at redshifts of 0.1-4. Some evolve s…
Cosmological Constraints from Measurements of Type Ia Supernovae discovered during the first 1.5 years of the Pan-STARRS1 Survey
A. Rest, D. Scolnic, R. J. Foley +46
We present griz light curves of 146 spectroscopically confirmed Type Ia Supernovae () discovered during the first 1.5 years of the Pan-STARRS1 Medium Deep Survey. T…
Systematic Uncertainties Associated with the Cosmological Analysis of the First Pan-STARRS1 Type Ia Supernova Sample
D. Scolnic, A. Rest, A. Riess +46
We probe the systematic uncertainties from 113 Type Ia supernovae (SNIa) in the Pan-STARRS1 (PS1) sample along with 197 SN Ia from a combination of low-redshift surveys. The compan…
The supernova CSS121015:004244+132827: a clue for understanding super-luminous supernovae
S. Benetti, M. Nicholl, E. Cappellaro +24
We present optical photometry and spectra of the super luminous type II/IIn supernova CSS121015:004244+132827 (z=0.2868) spanning epochs from -30 days (rest frame) to more than 200…
The first month of evolution of the slow rising type II-P SN 2013ej in M74
S. Valenti, D. Sand, A. Pastorello +14
We present early photometric and spectroscopic observations of SN 2013ej, a bright type IIP supernova in M74. SN 2013ej is one of the closest SNe ever discovered. The available arc…
On the progenitor of the Type Ic SN 2013dk in the Antennae Galaxies
Nancy Elias-Rosa, Andrea Pastorello, Justyn R. Maund +7
We report the results of our search for the progenitor candidate of SN 2013dk, a Type Ic supernova (SN) that exploded in the Antennae Galaxy system. We compare pre-explosion Hubble…
SN 2012ca: a stripped envelope core-collapse SN interacting with dense circumstellar medium
C. Inserra, S. J. Smartt, R. Scalzo +16
We report optical and near-infrared observations of SN 2012ca with the Public ESO Spectroscopy Survey of Transient Objects (PESSTO), spread over one year since discovery. The super…
Comparison of progenitor mass estimates for the type IIP SN 2012A
L. Tomasella, E. Cappellaro, M. Fraser +24
We present the one-year long observing campaign of SN 2012A which exploded in the nearby (9.8 Mpc) irregular galaxy NGC 3239. The photometric evolution is that of a normal type IIP…
