The Palomar Transient Factory: system overview, performance and first results
The Palomar Transient Factory (PTF) is a fully-automated, wide-field survey aimed at a systematic exploration of the optical transient sky. The transient survey is performed using a new 8.1 square
THE FIRST SYSTEMATIC STUDY OF TYPE Ibc SUPERNOVA MULTI-BAND LIGHT CURVES
We present detailed optical photometry for 25 Type Ibc supernovae (SNe Ibc) within d 150 Mpc obtained with the robotic Palomar 60 inch telescope in 2004-2007. This study represents the first uniform,
Hydrogen-poor superluminous stellar explosions
TLDR
Observations of a class of luminous supernovae whose properties cannot be explained by any of the following processes: radioactive decay of freshly synthesized elements, explosion shock in the envelope of a supergiant star, and interaction between the debris and slowly moving, hydrogen-rich circumstellar material.
Relativistic ejecta from X-ray flash XRF 060218 and the rate of cosmic explosions
TLDR
Radio and X-ray observations of XRF 060218 (associated with supernova SN 2006aj), the second-nearest GRB identified until now, are reported, showing that this event is a hundred times less energetic but ten times more common than cosmological GRBs.
An Extremely Luminous Panchromatic Outburst from the Nucleus of a Distant Galaxy
TLDR
Multiwavelength observations of a unique γ-ray–selected transient detected by the Swift satellite, accompanied by bright emission across the electromagnetic spectrum, and whose properties are unlike any previously observed source are presented.
A Possible Relativistic Jetted Outburst from a Massive Black Hole Fed by a Tidally Disrupted Star
TLDR
Observations suggest a sudden accretion event onto a central MBH of mass about 106 to 107 solar masses, which leads to a natural analogy of Sw 1644+57 to a temporary smaller-scale blazar.
Supernova SN 2011fe from an exploding carbon–oxygen white dwarf star
TLDR
Early observations of type Ia supernova SN 2011fe in the galaxy M101 at a distance from Earth of 6.4 megaparsecs find that the exploding star was probably a carbon–oxygen white dwarf, and from the lack of an early shock it is concluded that the companion was likely a main-sequence star.
An extremely luminous X-ray outburst at the birth of a supernova
TLDR
This work reports the serendipitous discovery of a supernova at the time of the explosion, marked by an extremely luminous X-ray outburst, and attributes the outburst to the ‘break-out’ of the supernova shock wave from the progenitor star, and shows that the inferred rate of such events agrees with that of all core-collapse supernovae.
A γ-ray burst at a redshift of z ≈ 8.2
Long-duration γ-ray bursts (GRBs) are thought to result from the explosions of certain massive stars, and some are bright enough that they should be observable out to redshifts of z > 20 using
A continuum of H- to He-rich tidal disruption candidates with a preference for E+A galaxies
We present the results of a Palomar Transient Factory (PTF) archival search for blue transients that lie in the magnitude range between "normal" core-collapse and superluminous supernovae (i.e., with
