Euclid STAR Prize 2019 Student Award

Morgan A. Schmitz

Morgan A. Schmitz is a PhD student at CEA Paris-Saclay, France. He is expected to graduate in the fall of 2019.

The main focus of his research so far has been on developing methods for the non-parametric modeling of the VIS Point Spread Function. This work has led him to dabble in galaxy shape measurement, the propagation of errors to cosmic shear measurements, deconvolution techniques and numerical optimal transport. Morgan is also an alumni of the first three sessions of the Euclid France Summer School. There, he started collaborating with fellow Euclid members on a project on weak lensing peak counts.


Euclid STAR Prize 2019 Junior Scientist Award

James Nightingale

James Nightingale is an observational astronomer and post-doctoral researcher at the Centre for Extragalactic Astronomy at Durham University. He completed his PhD at the University of Nottingham under the supervision of Dr. Simon Dye, where he developed PyAutoens, a software for modeling strong gravitational lenses. He’s passionate about dark matter cosmology, big data challenges and open source software.

In Euclid, he works on charge transfer inefficiency, an effect caused by radiation damage to Euclid’s CCD imaging detectors, which ‘smears’ the images they acquire. If not corrected for, this smearing of the galaxy images will bias shape measurement and weak lensing science. At Durham, he is developing software which models this effect during the read-out process of a CCD and uses this model to correct Euclid science imaging.

Daniele Tavagnacco

Daniele Tavagnacco is an astrophysicist and currently working as junior scientist at the INAF-OATs in Trieste. After his PhD in physics focused on the PLANCK-LFI instrument systematic effects, he spent one year in Antarctica developing and maintaining ground telescopes for IR observations and became the technical manager of ITM telescope. Then he joined the Euclid collaboration as SDC-IT Dev member of the SGS where he currently works as software engineer for LE3.

His role within Euclid is the development and integration of the LE3 Processing Functions under the responsibility of SDC-IT. This includes adapting the PFs to the Euclid software structure and coding rules, the preparation of unit tests and, for the most resource demanding ones, their re-design and optimization.


Euclid STAR Prize 2019 Senior Scientist Award

Reiko Nakajima

Reiko Nakajima is a researcher in astronomy at the Argelander Institut für Astronomie in Bonn, Germany. After getting her physics and engineering degrees and then working briefly in the industry, she obtained her PhD in Physics and Astronomy at the University of Pennsylvania and was a post-doctoral researcher at Berkeley. Upon arrival at Bonn, she started working on Euclid weak lensing science in 2011 and has since been planning systematic tests for Euclid Weak Lensing Science, while reading through the mountain of Euclid documentations.

Her current main task is the upgrade of the VIS portion of the Calibration Concept Document — Part B (CalCD-B). The current CalCD-B is obsolete — between the swift progress in the VIS instrument characterization and the loss of a key VIS instrument scientist from the Euclid project in 2015, many new calibration items are requiring immediate attention for implementation in OU-VIS. Her job therefore is to act as a liaison between CalWG, VIS IDT, WL-SWG, OU-VIS, and a few other groups of multiple-letter acronym, to rewrite the CalCD-B that suits the our current understanding of the VIS instrument performances, and to ensure necessary VIS calibrations are implemented for our weak lensing science requirements.


Euclid STAR Prize 2019 Leadership & Coordination Award

Hervé Aussel

Hervé Aussel is a CNRS researcher at the AIM laboratory in Saclay, working on the evolution of galaxies. After graduating in 1999, he was a postdoc in Padova, then JCMT Fellow (2000-2003) and Pan-STARRS Junior Researcher (2003-2004) at the University of Hawaii. Initially observing galaxies in the infrared (ISO, Spitzer, Herschel, NIKA2) he quickly adopted a broader multi-wavelength view through his participation to the COSMOS survey. He thus joined Euclid in 2012 from the Legacy side, but has – since his involvement in the Euclid Science Performance Verification – happily taken a more cosmological turn in his career, taking a strong interest in the connection between galaxies and their hosting dark matter halos. He will be Euclid Science Ground Segment Scientist from July 2019 onward.

NISP Detector team, Lyon group (from left to right): Alain Castera, Gérard Smadja, Anne Ealet, Clement Buton, Sylvain Ferriol, and Bogna Kubik

The characterization team’s expertise is based on an early experience with IR detectors in the framework of the SNAP collaboration and expanded to the highest level within the Euclid project. The team members combine strong complementary skills: mechanical and thermal design of the bench, software development for acquisition and bench control & automation, instrumentation, test procedures of pixel detectors. Thanks to the close collaboration of CPPM & IPNL, the team has developed and validated dedicated test facilities of high quality and excellent running efficiency with a fully automated acquisition scheme. The characterization of the 20 IR detectors has taken over one year with 85% efficiency, leading to 400 TB of data from which the team will derive pixel map products and models for the SGS. The emphasis during these tests was the collection of data to enable the control of relative pixel gains, non-linearities, and persistence.
