The stellar-substellar limit in the large scale survey Euclid | Closing date: 2024-04-15 Contact: Celine Reyle |
The successful applicant will work on the identification of ultra cool dwarfs in Euclid fields, and may propose new identification techniques and explore the possibility of using the precise PSF of Euclid to identify close binaries. Other challenges can be addressed, such as to determine the luminosity function, infer the most likely low-mass end of the initial mass function and explore its degree of universality in different components of the Milky Way.
The candidate will be working with the international Euclid UCD group within the consortium, as well as the Gaia UCD team. | ▸ more | Euclid is a space mission led by the European Space Agency (ESA) to conduct a deep, single-epoch survey of 15,000 deg2 of sky with visible and near-infrared photometry and spectroscopy, and 40 deg2 multi-epoch very deep surveys. Its primary science goal is to investigate the geometry of the dark universe by mapping the distribution and shapes of galaxies. The unprecedented combination of sensitivity, areal coverage, spatial resolution, data homogeneity and spectral information will naturally be of tremendous benefit to other areas of astrophysics.
Ultra cool dwarfs (UCDs) are the lowest-mass, coldest, and faintest products of star formation. They are defined as objects with M7 and later spectral type objects. UCDs are of particular interest since they include both very low-mass stars that slowly fuse hydrogen, and brown dwarfs, which have insufficient mass to sustain hydrogen fusion in their cores, and cool down with time.
The Euclid wide survey will probe a very large volume and allow the detection of an unprecedented huge number of UCDs (> 1 000 000). The NIR colours are suitable to classify them, the only point-source contaminants being high redshift quasars. However, UCDs can be discriminated from QSOs thanks to the visible survey: UCDs VIS-NIR colours will be much redder or they will not be detected in the visible. Most of those with spectral type M7 to L5 have been discovered thanks to Gaia, completed by ground based or space telescopes in the NIR for the latter type brown dwarfs. With its deep and large cover in the NIR, Euclid is expected to complete the census and push the volume for L and T dwarfs.
Thanks to the depth of the NIR Euclid survey, we expect to use the UCDs as a probe of the oldest Milky Way populations and so learn more about the sub-stellar formation history at early times. In addition Euclid will offer a large sample of UCDs spanning a large metallicity range and open up a new window on the chemical evolution of the Milky Way.
Skills/Qualifications
Skill and experience required: The candidates will have a track record of research in a relevant area of expertise in astrophysics. The candidates will also have a record of submitting/publishing scientific research in leading astronomical journals, presenting their work at scientific conferences, workshops or seminars.
The candidates will ideally have some experience of working large scale surveys, and stellar populations, in particular low mass stars and brown dwarfs.
Specific Requirements
Applications should be sent to Céline Reylé and should be accompanied by PDF versions of a CV, a list of publications, and a personal statement/cover letter (maximum one side of A4 paper) explaining the motivation for applying, summarizing the research interests and the project. It should also include the contact details of two referees.
The position is funded by the Université of Franche-Comté, for 12 months, renewable.

The supernova and transient group are actively involved in several transient surveys, including the Zwicky Transient Facility, the upcoming La Silla Southern Sky Survey (LS4), and the Time Domain Extragalactic Survey (TiDES) of the multi-object spectroscopic survey, 4MOST. The data from these surveys, combined with the huge rate of data from the Rubin Observatory?s LSST along with detailed comparisons via machine-learning with explosion models, will revolutionise our understanding of extragalactic transient phenomena. The group has access to dedicated computing servers and high-performance facilities through Trinity?s Research IT infrastructure and the Irish Centre for High-End Computing (ICHEC).
Successful applicants will have the possibility to focus their research based on their skills and interests. Potential projects could be related to exploiting these new data in the context of understanding how white dwarfs explode, their host galaxy dependencies, and their use for new cosmological measurements. More computationally-focussed projects are also possible, such as rapid radiative transfer modelling of explosive transients and/or the development of novel machine-learning techniques for comparing explosion models to these new datasets.
The successful candidate will become part of the Trinity Astrophysics Group and will be encouraged to actively contribute with other researchers in the lively, diverse, and friendly research environment at Trinity College Dublin, as well as become a member of the international collaborations the group are part of. Trinity?s campus is in the heart of Dublin, which hosts several other research institutes, with an active community in supernova and transient research.
Applicants must have achieved, by the start date a 1st or upper 2nd class (I or II.I, or equivalent: http://tiny.cc/grtab) in a Masters or four-year undergraduate degree in astrophysics or a related field. The nominal start date is September 1st, 2024, but a later starting date can be negotiated. This PhD studentship is open to EU/EEA/UK applicants (subject to confirmation of status), though full consideration will be given to exceptional non-EU candidates. The position is fully funded for four years (as is standard in Irish Universities) and covers tuition fees and a tax-free stipend of 25000 euro per year, as well as a laptop/computer and work-related travel costs.
Applicants should submit a CV (max 2-pages), including the names of two referees who will be contacted if shortlisted, and a statement (max one-page) outlining their academic experience and motivation for pursuing this PhD position. Complete applications received by the application deadline of 20th February 2024 will receive full consideration. Applications from traditionally under-represented minorities in physics and astronomy are particularly welcomed.
Applications, as well as any queries, can be submitted via email to astrojobs @ tcd.ie - 'Supernovae and Transients PhD' application in the subject heading.

Spectro-perfectionism for high-fidelity spectroscopy | Closing date: 2024-02-15 Contact: Guido Cupani |
We are looking for a strong candidate with 3-year research experience in astrophysics, computer science, or engineering, to implement a spectro-perfectionist data reduction software for the super-stable spectrograph HARPS. The successful candidate will work for 1 year (extendable to 2) at INAF-OATs in a stimulating environment, handling state-of-the-art observational data and analysis tools. Full information at http://www.inaf.it/it/lavora-con-noi/assegni-di-ricerca/assegno-di-ricerca-dal-titolo-design-and-implementation-of-a-spectro-perfectionist-reduction-tool-for-the-harps-instrument201d | ▸ more | The need for better accuracy, precision, and stability in spectroscopical observations is part of a quest for what can be called ?spectral fidelity?, i.e. the reliable reconstruction of the original spectral information (flux as a function of wavelength). Spectral fidelity can be achieved only when all steps of the data flow chain are covered by adequate instruments, adequate calibration schemes, and adequate tools for data reduction and analysis. Both instrumentation and calibration have undergone a major overhaul in the last 20 years, with the adoption of fibre injection optimised for scrambling capabilities, simultaneous wavelength calibration with Laser Frequency Combs (LFCs), and temperature- and pressure-stabilised vacuum vessels. The last generation of optical echelle fiber-fed spectrographs, like HARPS and ESPRESSO, brought the wavelength accuracy and precision down to the tens of cm/s, and are acting as proper pathfinders for the ELT-era instruments, which will require a tenfold improvement on this figure to achieve the scientific goals of current-age cosmology and astrophysics, e.g.:
(a) The measurement of fundamental constant variability from the relative wavelength shift of absorption lines observed towards distant quasars;
(b) The direct measurement of the expansion of the universe from a redshift drift of the spectral features of distant sources;
(c) The assessment of primordial nucleosynthesis from an accurate abundance measurement of Deuterium in low-metallicity systems;
(d) The measurement of the gravitational redshift on the Sun and other stars, and the determination of the nature of gravity in weak field regime.
Data treatment, unfortunately, is lagging behind. The main limitation is that the typical approach to spectral reduction is still based on reverse modelling: given the detector output, the input spectrum is recovered by tracing the signal along the echelle orders and integrating it along the transverse direction with an appropriate weighting (?optimal extraction?). While fast and robust, this method is generally wrong, as it assumes that the instrument point-spread function (PSF) is separable along the CCD axes (which is never the case for curved echelle orders). The correct approach (?spectro-perfectionism? or SP; Bolton and Schlegel (2010), PASP 122, 248) is based on forward modelling, similar to what is commonly applied e.g. to data in the X band: given the instrument characteristics, the detector output is interpreted as the result of a linear transformation of the input spectrum, which can be recovered by inverting the transformation itself. The advantage of SP is indisputable, as it allows a simultaneous modelling of the target signal (including its contaminants, e.g. the sky background) and of the instrumental signature (including R). Analysis of simulated data by shows that the approach is more than 10 times better than optimal extraction, according to different figures of merit. The cost is an increased technical and computational difficulty in evaluating and inverting the large matrices that characterise the instrumental.
The aim of this project is to implement the first full SP approach for super-stable spectrographs, namely HARPS, and to validate it on archival HARPS data. The time is ripe to bring SP to the high-precision cosmology arena it was originally meant for. In the case of HARPS, the sizes of the matrix to be inverted is of the order of 10^7, a figure that is now manageable in light of the following technical improvements:
(a) Computing capabilities have increased significantly (for CPUs: roughly 1.5x in clock speed and 3x in number of cores; for GPUS: roughly 3x in clock speed, 15x in VRAM size, and 30x in number of CUDA cores);
(b) The problem can be downscaled by splitting the spectra into chunks to reduce the matrix size.
The software will be written mostly in Python using common libraries (e.g. NumPy, Scipy, Astropy, XLA) and released as a self-standing module through standard channels (eg. INAF GitLab, pip, Anaconda). We will interface it with the official ESO HARPS reduction pipeline and with the Astrocook data analysis package (Cupani et al. 2020) to the benefit of the end users. We will also develop a pluggable SP-module to be adapted to other instruments, specifically HARPS-N and ESPRESSO. We will finally study the possibility to extend the SP approach to the next-generation spectrographs, like ELT ANDES, using state-of-the-art simulated data to investigate possible critical points.
The development of a full-SP data reduction tool for HARPS is impactful at two levels:
(a) It will boost the instrument?s performance, exploiting its large amount of archival data (including double LFC references). HARPS?s smaller detector size make the problem of evaluating and inverting A more tractable compared to ESPRESSO; in fact, a detailed assessment of the HARPS PSF from LFC frames is already in progress.
(b) On a wider perspective, it will foster the extension of the approach to different contexts. The HARPS test-case will help exploring, e.g., the degree to which the definition of A can be approximated without undermining the quality of the reduction, or the possibility of adapting SP to long-slit spectrographs, like the future VLT CUBES.
