Towards a physical understanding of the thermal background in large ground-based telescopes
Leonard Burtscher, Ioannis Politopoulos, Sergio Fernández-Acosta +11
Ground-based thermal-infrared observations have a unique scientific potential, but are also extremely challenging due to the need to accurately subtract the high thermal background…
Focal Plane Wavefront Sensing on SUBARU/SCExAO
Sebastien Vievard, Steven P. Bos, Frederic Cassaing +20
Focal plane wavefront sensing is an elegant solution for wavefront sensing since near-focal images of any source taken by a detector show distortions in the presence of aberrations…
Exploiting symmetries and progressive refinement for apodized pupil Lyot coronagraph design
Emiel H. Por, Rémi Soummer, James Noss +1
Modern coronagraph design relies on advanced, large-scale optimization processes that require an ever increasing amount of computational resources. In this paper, we restrict ourse…
Design of the Life Signature Detection Polarimeter LSDpol
Christoph U. Keller, Frans Snik, C. H. Lucas Patty +11
Many biologically produced chiral molecules such as amino acids and sugars show a preference for left or right handedness (homochirality). Light reflected by biological materials s…
Estimating low-order aberrations through a Lyot coronagraph with a Zernike wavefront sensor for exoplanet imaging
Raphaël Pourcelot, Mamadou N'Diaye, Greg Brady +13
Imaging exo-Earths is an exciting but challenging task because of the 10^-10 contrast ratio between these planets and their host star at separations narrower than 100 mas. Large se…
A smartphone-based arbitrary scene projector for detector testing and instrument performance evaluation
Thibaut Prod'homme, Patricia Liebing, Peter Verhoeve +6
Using the high-resolution OLED screen of a smartphone to project arbitrary scenes and patterns can open a complete new dimension for testing sensors in the visible. Based on an ori…
Pyxel: the collaborative detection simulation framework

Pyxel is a novel python tool for end-to-end detection chain simulation i.e. from detector optical effects to readout electronics effects. It is an easy-to-use framework to host and…
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 Early Data Release 3: Modelling and calibration of Gaia's point and line spread functions
N. Rowell, M. Davidson, L. Lindegren +18
Context: The unprecedented astrometric precision of the Gaia mission relies on accurate estimates of the locations of sources in the Gaia data stream. This is ultimately performed…
High contrast imaging for the enhanced resolution imager and spectrometer (ERIS)
Matthew A. Kenworthy, Frans Snik, Christoph U. Keller +9
ERIS is a diffraction limited thermal infrared imager and spectrograph for the Very Large Telescope UT4. One of the science cases for ERIS is the detection and characterization of…
Gaia Early Data Release 3: Photometric content and validation
M. Riello, F. De Angeli, D. W. Evans +39
Gaia Early Data Release 3 contains astrometry and photometry results for about 1.8 billion sources based on observations collected by the ESA Gaia satellite during the first 34 mon…
Calibration of the instrumental polarization effects of SCExAO-CHARIS' spectropolarimetric mode
Rob G. van Holstein, Steven P. Bos, Jasper Ruigrok +18
SCExAO at the Subaru telescope is a visible and near-infrared high-contrast imaging instrument employing extreme adaptive optics and coronagraphy. The instrument feeds the near-inf…
The Roles of Astronomers in the Astronomy Education Ecosystem: A Research-Based Perspective
Stephen Pompea, Pedro Russo
Astronomers have played many roles in their engagement with the larger astronomy education ecosystem. Their activities have served both the formal and informal education communitie…
The LOFAR Two Meter Sky Survey: Deep Fields, I -- Direction-dependent calibration and imaging
C. Tasse, T. Shimwell, M. J. Hardcastle +29
The Low Frequency Array (LOFAR) is an ideal instrument to conduct deep extragalactic surveys. It has a large field of view and is sensitive to large scale and compact emission. It…
A non-energetic mechanism for glycine formation in the interstellar medium
S. Ioppolo, G. Fedoseev, K. -J. Chuang +8
The detection of the amino acid glycine and its amine precursor methylamine on the comet 67P/Churyumov-Gerasimenko by the Rosetta mission provides strong evidence for a cosmic orig…
Unveiling the rarest morphologies of the LOFAR Two-metre Sky Survey radio source population with self-organised maps
