The cosmic web's Lyman- glow at ; hydrodynamic models, dust, and wide-field, narrow-band detection
Oleksii Sokoliuk, John K. Webb, Kenneth M. Lanzetta +12
The diffuse Lyman- glow of the cosmic web has long been predicted but has so far eluded direct detection over cosmologically significant volumes. We construct synthetic Lyman-$α…
Constraints on the Progenitor System of the Type Ia Supernova SN 2011fe/PTF11kly
Weidong Li, Joshua S. Bloom, Philipp Podsiadlowski +25
Type Ia supernovae (SNe) serve as a fundamental pillar of modern cosmology, owing to their large luminosity and a well-defined relationship between light-curve shape and peak brigh…
Early radio and X-ray observations of the youngest nearby type Ia supernova PTF11kly (SN 2011fe)
Assaf Horesh, S. R. Kulkarni, Derek B. Fox +20
On August 24 (UT) the Palomar Transient Factory (PTF) discovered PTF11kly (SN 2011fe), the youngest and most nearby type Ia supernova (SN Ia) in decades. We followed this event up…
Wandering Stars: an Origin of Escaped Populations
Maureen Teyssier, Kathryn V. Johnston, Michael Shara
We demonstrate that stars beyond the virial radii of galaxies may be generated by the gravitational impulse received by a satellite as it passes through the pericenter of its orbit…
Exploring the Optical Transient Sky with the Palomar Transient Factory
Arne Rau, Shrinivas R. Kulkarni, Nicholas M. Law +21
The Palomar Transient Factory (PTF) is a wide-field experiment designed to investigate the optical transient and variable sky on time scales from minutes to years. PTF uses the CFH…
