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…
Gaia Data Release 1: The reference frame and the optical properties of ICRF sources
F. Mignard, S. Klioner, L. Lindegren +18
As part of the data processing for Gaia Data Release~1 (Gaia DR1) a special astrometric solution was computed, the so-called auxiliary quasar solution. This gives positions for sel…
Gaia Data Release 1. Summary of the astrometric, photometric, and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +5
At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magni…
The Gaia mission
Gaia Collaboration
Gaia is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original…
The Far-Infrared Surveyor Mission Study: Paper I, the Genesis
M. Meixner, A. Cooray, R. Carter +27
This paper describes the beginning of the Far-Infrared Surveyor mission study for NASA's Astrophysics Decadal 2020. We describe the scope of the study, and the open process approac…
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…
