1. HRMOS Science workshop (18-22 October 2021, online/in-person)

The meeting will be a hybrid of online and in-person (Firenze, Italy and Sydney, Australia), and run for half-days taking into account different timezones.

Registration and Abstract Submission
Deadline: 8 September 2021

To submit an abstract you need to open an INDICO Account and login with Indico as the authentication provider. When creating your INDICO account, you will be asked about the event you are attending, and the relevant contact person. Please use the following text: “HRMOS workshop. INAF Contact: Laura Magrini”. Your account should be activated within one or two working days.

No registration fees

The High Resolution Multi-Object Spectrograph (HRMOS) is a proposed facility instrument for the ESO’s VLT, following the initial presentation at the VLT 2030 workshop. HRMOS provides a combination of capabilities essential to carry out breakthrough science across a broad range of active research areas from Galactic and Local Group Archaeology to Stellar Astrophysics and Exoplanet studies. HRMOS fills a gap in capabilities amongst the landscape of future instrumentation planned for the next decade. The key capability of HRMOS is high spectral resolution (R = 60,000 – 80,000) with multi-object (50-100) capabilities and stability that provides radial velocity precision (~10m/s). Initial designs predict a SNR=30 is achievable within 1hr for mag(AB) = 17-18 depending on resolution. The combination of high resolution and multiplex going to relatively bluer wavelengths (from 380nm), is truly a spectrograph that will push the boundaries of our knowledge and is envisioned as a workhorse instrument in the future.

This conference aims to bring together the International scientific community, to propose and discuss science projects where HRMOS will have a strong impact due to its unparalleled capabilities, as well as identifying the areas where it will provide unique synergies with existing and forthcoming large surveys and facilities such as 4MOST, WEAVE, MOONS and the ELTs. 

This meeting is your opportunity to present your science with HRMOS and join the collaboration to push forward the HRMOS project in preparation for an upcoming White paper call. 

Format and Contributions 
Given the current pandemic situation, the meeting will be run online on alternating timezones. 18-19 October will be nominally 9am-1pm CEST, while 20-21 October will be nominally 9am-1pm AEDT. The exact times may change.

We are concurrently organising the option for meeting in-person in Firenze, Italy on the 18/19 October, and in Sydney, Australia on the 20/21 October (subject to local laws at the time). The final session on the Friday 22 October will be exclusively online. All presentations will be recorded and made available for the registered participants. 

Participants are strongly encouraged to submit a short abstract describing the science questions and topics they would like to address with HRMOS. We anticipate a talk length of 20min for contributed presentations.

A detailed schedule will be made available closer to the meeting, though we expect to discuss the following (non-exhaustive) list of topics which formed part of the initial science case; new ideas are very much welcome:

  • Origins of the Heavy elements
  • Properties of the First Stars
  • Galactic Archeology at High Spectral Resolution
  • Exo-planets in Star clusters, Bulge and other Galaxies
  • Young stars and Doppler Tomography of Magnetic structures
  • Chemical Evolution of the MW Satellites
  • Star clusters in High Resolution
  • Stellar abundances and Chemical tagging
  • Synergies with current and future facilities

The current options for the instrument concept will also be presented and discussed.

We invite you to circulate this first announcement among your colleagues. We apologise if you receive this more than once. For any questions, do not hesitate to contact Gayandhi, Sofia or Eline.

4. Two PhD positions in observational cosmology at CPPM, Marseille

Application deadline: July 11th

Topic: Constraining dark-energy and alternative models to general relativity with measurements of the growth rate of structures using galaxy surveys

The context: More than twenty years after the discovery of the accelerated nature of the Universe’s expansion, there is still no definitive explanation for its physical origin. Several types of dark-energy or even alternatives/extensions to general relativity have been proposed in the literature attempting to explain the acceleration of the expansion. By accurately measuring of both expansion and growth rates as a function of cosmic time, we can learn more about this cosmological mystery. Those measurements are the scientific goal of current and future experiments such as the Dark Energy Spectroscopic Instrument (DESI), the Zwicky Transient Facility (ZTF), Euclid and the Vera Rubin Observatory Legacy Survey of Space and Time (Rubin-LSST).

The positions: The Initiative of Aix-Marseille A*Midex is funding two PhD positions at the Centre de Physique de Particules de Marseille (CPPM) starting in October 2021 for a duration of three years in the topic of observational cosmology. The goal is to measure the growth-rate of structures using galaxies from DESI or Euclid, eventually combining them with direct peculiar velocities estimates from ZTF or Rubin-LSST type-Ia supernovae. The PhD projects will include extensive work on data analysis, both simulated and observed, development of models and estimators, and the use of high-performance computing centres across the globe. Experience with cosmology, scientific computing, statistics and data analysis is highly recommended.

The host institution: The Centre de Physique de Particules de Marseille (CPPM) is a multi-disciplinary CNRS laboratory hosted by the Aix-Marseille Université with top researchers in the domains of particle physics, neutrinos, astroparticles, and cosmology. The CPPM participates in the construction and scientific exploitation of the main ongoing and future cosmological projects such as the Dark Energy Spectroscopic Instrument (DESI), the Zwicky Transient Facility (ZTF), Euclid and the Vera Rubin Observatory Legacy Survey of Space and Time (Rubin-LSST). The cosmology group is a dynamic team composed of PhD students, postdocs, engineers and researchers experts in the clustering of galaxies, cosmic voids, type-Ia supernovae. The CPPM is a close partner of the Laboratoire d’Astrophysique de Marseille and the Centre de Physique Théorique, both in the Marseille area. 

To apply: The candidates should send to bautista@cppm.in2p3.fr the following items : 
– a CV
– a one-page statement of their motivations
– the latest available academic transcript of records
– one recommendation letter to be sent directly to bautista@cppm.in2p3.fr by the recommender 

Included Benefits: French national medical/dental insurance, maternity/paternity leave, lunch subsidies, family supplement for children, participation to public transport fees, pension contributions. School is free in France for all children above 3. French lessons are also offered by the institution.
