Core-collapse supernovae missed by optical surveys
S. Mattila, T. Dahlen, A. Efstathiou +7
We estimate the fraction of core-collapse supernovae (CCSNe) that remain undetected by optical SN searches due to obscuration by large amounts of dust in their host galaxies. This…
Near-IR search for lensed supernovae behind galaxy clusters: III. Implications for cluster modeling and cosmology
Teresa Riehm, Edvard Mörtsell, Ariel Goobar +6
Massive galaxy clusters at intermediate redshifts act as gravitational lenses that can magnify supernovae (SNe) occurring in background galaxies. We assess the possibility to use l…
Near-IR search for lensed supernovae behind galaxy clusters: I. Observations and transient detection efficiency
V. Stanishev, A. Goobar, K. Paech +11
Massive galaxy clusters at intermediate redshift can magnify the flux of distant background sources by several magnitudes and we exploit this effect to search for lensed distant su…
GRB 070714B - Discovery of the Highest Spectroscopically Confirmed Short Burst Redshift
J. F. Graham, A. S. Fruchter, A. J. Levan +10
We detect the optical afterglow and host galaxy of GRB 070714B. Our observations of the afterglow show an initial plateau in the lightcurve for approximately the first 5 to 25 minu…
GRB 070714B - Discovery of the Highest Spectroscopically Confirmed Short Burst Redshift
J. F. Graham, A. S. Fruchter, A. J. Levan +5
Gemini Nod & Shuffle spectroscopy on the host of the short GRB 070714B shows a single emission line at 7167 angstroms which, based on a grizJHK photometric redshift, we conclude is…
Corrections for gravitational lensing of supernovae: better than average?
Christofer Gunnarsson, Tomas Dahlen, Ariel Goobar +2
We investigate the possibility of correcting for the magnification due to gravitational lensing of standard candle sources, such as Type Ia supernovae. Our method uses the observed…
SNOC: a Monte-Carlo simulation package for high-z supernova observations
A. Goobar, E. Mortsell, R. Amanullah +3
We present a Monte-Carlo package for simulation of high-redshift supernova data, SNOC. Optical and near-infrared photons from supernovae are ray-traced over cosmological distances…
