PSF Estimation in Crowded Astronomical Imagery as a Convolutional Dictionary Learning Problem
Brendt Wohlberg, Przemek Wozniak
We present a new algorithm for estimating the Point Spread Function (PSF) in wide-field astronomical images with extreme source crowding. Robust and accurate PSF estimation in crow…
A UV Resonance Line Echo from a Shell Around a Hydrogen-Poor Superluminous Supernova
R. Lunnan, C. Fransson, P. M. Vreeswijk +21
Hydrogen-poor superluminous supernovae (SLSN-I) are a class of rare and energetic explosions discovered in untargeted transient surveys in the past decade. The progenitor stars and…
Energetic eruptions leading to a peculiar hydrogen-rich explosion of a massive star
Iair Arcavi, D. Andrew Howell, Daniel Kasen +50
Every supernova hitherto observed has been considered to be the terminal explosion of a star. Moreover, all supernovae with absorption lines in their spectra show those lines decre…
iPTF16asu: A Luminous, Rapidly-Evolving, and High-Velocity Supernova
L. Whitesides, R. Lunnan, M. M. Kasliwal +23
Wide-field surveys are discovering a growing number of rare transients whose physical origin is not yet well understood. Here, we present optical and UV data and analysis of iPTF16…
Confined Dense Circumstellar Material Surrounding a Regular Type II Supernova: The Unique Flash-Spectroscopy Event of SN 2013fs
O. Yaron, D. A. Perley, A. Gal-Yam +30
With the advent of new wide-field, high-cadence optical transient surveys, our understanding of the diversity of core-collapse supernovae has grown tremendously in the last decade.…
iPTF14yb: The First Discovery of a GRB Afterglow Independent of a High-Energy Trigger
S. Bradley Cenko, Alex L. Urban, Daniel A. Perley +34
We report here the discovery by the Intermediate Palomar Transient Factory (iPTF) of iPTF14yb, a luminous ( mag), cosmological (redshift 1.9733), rapidly fading…
