Gaia Data Release 3: Gaia scan-angle dependent signals and spurious periods
B. Holl, C. Fabricius, J. Portell +23
Context: Gaia DR3 time series data may contain spurious signals related to the time-dependent scan angle. Aims: We aim to explain the origin of scan-angle dependent signals and how…
Gaia Early Data Release 3: The astrometric solution
L. Lindegren, S. A. Klioner, J. Hernández +94
Gaia Early Data Release 3 (Gaia EDR3) contains results for 1.812 billion sources in the magnitude range G = 3 to 21 based on observations collected by the European Space Agency Gai…
Gaia Data Release 2. Short-timescale variability processing and analysis
M. Roelens, L. Eyer, N. Mowlavi +13
The Gaia DR2 sample of short-timescale variable candidates results from the investigation of the first 22 months of Gaia photometry for a subsample of sources at the Gaia faint end…
Gaia Data Release 2: Properties and validation of the radial velocities
D. Katz, P. Sartoretti, M. Cropper +51
For Gaia DR2 (GDR2), 280 million spectra, collected by the RVS instrument on-board Gaia, were processed and median radial velocities were derived for 9.8 million sources brighter t…
Gaia Radial Velocity Spectrometer
M. Cropper, D. Katz, P. Sartoretti +40
This paper presents the specification, design, and development of the Radial Velocity Spectrometer (RVS) on the European Space Agency's Gaia mission. Starting with the rationale fo…
Gaia Data Release 2: Photometric content and validation
D. W. Evans, M. Riello, F. De Angeli +9
Aims. We describe the photometric content of the second data release of the Gaia project (Gaia DR2) and its validation along with the quality of the data. Methods. The validation w…
The Milky Way's halo in 6D: Gaia's Radial Velocity Spectrometer performance
George Seabroke, Mark Cropper, David Katz +9
Gaia's Radial Velocity Spectrometer (RVS) has been operating in routine phase for over one year since initial commissioning. RVS continues to work well but the higher than expected…
Gaia on-board metrology: basic angle and best focus
A. Mora, M. Biermann, A. G. A. Brown +21
The Gaia payload ensures maximum passive stability using a single material, SiC, for most of its elements. Dedicated metrology instruments are, however, required to carry out two f…
Observing Extended Sources with the \Herschel SPIRE Fourier Transform Spectrometer
Ronin Wu, Edward T. Polehampton, Mireya Etxaluze +20
The Spectral and Photometric Imaging Receiver (SPIRE) on the European Space Agency's Herschel Space Observatory utilizes a pioneering design for its imaging spectrometer in the for…
Impacts of The Radiation Environment At L2 On Bolometers Onboard The Herschel Space Observatory
Benoît Horeau, Olivier Boulade, Arnaud Claret +7
We present the effects of cosmic rays on the detectors onboard the Herschel satellite. We describe in particular the glitches observed on the two types of cryogenic far- infrared b…
The first release of data from the Herschel ATLAS: the SPIRE images
E. Pascale, R. Auld, A. Dariush +25
We have reduced the data taken with the Spectral and Photometric Imaging Receiver (SPIRE) photometer on board the Herschel Space Observatory in the Science Demonstration Phase (SDP…
Herschel-ATLAS: First data release of the Science Demonstration Phase source catalogues
E. E. Rigby, S. J. Maddox, L. Dunne +28
The Herschel-ATLAS is a survey of 550 square degrees with the Herschel Space Observatory in five far--infrared and submillimetre bands. The first data for the survey, observations…
H-ATLAS: PACS imaging for the Science Demonstration Phase
Edo Ibar, R. J. Ivison, A. Cava +26
We describe the reduction of data taken with the PACS instrument on board the Herschel Space Observatory in the Science Demonstration Phase of the Herschel-ATLAS (H-ATLAS) survey,…
In-flight calibration of the Herschel-SPIRE instrument
B. M. Swinyard, P. Ade, J-P. Baluteau +55
SPIRE, the Spectral and Photometric Imaging Receiver, is the Herschel Space Observatory's submillimetre camera and spectrometer. It contains a three-band imaging photometer operati…
