iPTF Discovers a Supernova Colliding with Its Companion StarRead MoreMay 21, 2015 • News Release
Type Ia supernovae, one of the most dazzling phenomena in the universe, are produced when white dwarfs explode with ferocious intensity. Although thousands of supernovae of this kind were found in the last decades, the process by which a white dwarf becomes one has been unclear. That began to change on May 3, 2014, when a team of Caltech astronomers working with the intermediate Palomar Transient Factory (iPTF) discovered a Type Ia supernova, designated iPTF14atg, in nearby galaxy IC831. The results from the iPTF data provides direct evidence for the existence of a companion star in a Type Ia supernova, and demonstrates that at least some Type Ia supernovae originate from the single-degenerate channel.
The 2015 iPTF Summer School at CaltechRead MoreFebruary 3, 2015 • News Release
The intermediate Palomar Transient Factory announces the 2015 iPTF Summer School, to be held at California Institute of Technology from August 24th - 28th, 2015. The purpose of this Summer School is three-fold: (i) Introduce time domain science to students by teaching them basic concepts and techniques using iPTF case studies; (ii) Acquaint new users on how to effectively use the iPTF public data release; (iii) Help the community prepare for time domain science in the LSST era by sharing our experience with iPTF. This Summer School is open to the entire astronomical community. The details for the Summer School can be found at http://www.ptf.caltech.edu/page/meetings.
