A novel method for transient detection in high-cadence optical surveys: Its application for a systematic search for novae in M31
Monika D. Soraisam, Marat Gilfanov, Thomas Kupfer +6
[abridged] In large-scale time-domain surveys, the processing of data, from procurement up to the detection of sources, is generally automated. One of the main challenges is contam…
The IPAC Image Subtraction and Discovery Pipeline for the intermediate Palomar Transient Factory
Frank Masci, Russ Laher, Umaa Rebbapragada +17
We describe the near real-time transient-source discovery engine for the intermediate Palomar Transient Factory (iPTF), currently in operations at the Infrared Processing and Analy…
Volumetric Survey Speed: A Figure of Merit for Transient Surveys
Eric C. Bellm
Time-domain surveys can exchange sky coverage for revisit frequency, complicating the comparison of their relative capabilities. By using different revisit intervals, a specific ca…
iPTF Search for an Optical Counterpart to Gravitational Wave Trigger GW150914
M. M. Kasliwal, S. B. Cenko, L. P. Singer +28
The intermediate Palomar Transient Factory (iPTF) autonomously responded to and promptly tiled the error region of the first gravitational wave event GW150914 to search for an opti…
