3. Gravitational Waves – A new window to the Universe (6 & 7 July 2021, online)

virtual mini-conference organized  by the Institute for the Physics of the Universe at Marseille on: Gravitational Waves – A new window to the Universe

The meeting is organized in two half days (6 & 7 July 2021 – afternoons 13:30-18:30 CET).

The main purpose of the meeting is to expose the IPhU community of physicists and astronomers to gravitational wave science.
The goal is to promote awareness and interactions that could favor the active participation of IPhU scientists
and students in major national and international gravitational wave projects and studies.

Physicists and astronomers who are not members of the IPhU are also very welcome to attend!

The first afternoon (Tue 6 Jul 2021) will be devoted to pedagogical talks about Gravitational Wave science:

  • Theory of the Gravitational Waves – Luc Blanchet (IAP, France)
  • From Sources to Detection – Luis Lehner (Perimeter Institute, Canada)
  • Detection of Gravitational Waves on Earth – Ligo/Virgo – Gabriela Gonzalez (Louisiana State Univ., USA)
  • Detection of Gravitational Waves in Space – LISA  –  Antoine Petiteau & Hubert Halloin (APC, France)

The second afternoon (Wed 7 Jul 2021) will focus on the presentation of the scientific activities related to several LISA working groups:

  • Astrophysics – Lucio Mayer (University of Zurich, Switzerland)
  • Cosmology – Germano Nardini (University of Stavanger, Norway)
  • Fundamental Physics – Marc Besançon (CEA/Irfu, France)
  • Waveforms –  Deirdre Shoemaker (Univ. of Texas at Austin, USA)

You can find the preliminary agenda and register (free of charge) now at: https://indico.in2p3.fr/event/23862/

The zoom link will be sent to the registered participants.

Do not hesitate to contact us at iphu-contact@univ-amu.fr should you have any question

4. 2021 GALAH Survey Science Meeting (22-24 June 2021, hybrid)
We are pleased to announce the 2021 GALAH Survey Science Meeting, to be held from 22 to 24 June 2021. It will have a hybrid format with people both online, and meeting in-person in Sydney, Australia.

The GALAH Survey is an ongoing, ambitious stellar spectroscopic survey of the local Galactic volume, acquiring high-resolution optical spectra for over one million stars with the HERMES spectrograph at the Anglo-Australian Telescope. GALAH had its Third Data Release in November 2020, which provided reduced spectra, stellar parameters, elemental abundances, and radial velocities for about 600000 stars. Subsequent to this release was the Third Early Data Release from the Gaia astrometric mission. The combination of these two data releases has provided an unprecedented view of our Galaxy. This conference aims to bring together researchers to present the latest research taking place using the GALAH survey, Gaia, and other stellar surveys.

The GALAH Survey and other stellar surveys facilitate a wide breadth of topics. Scientific themes we are interested in talks on include:

  • Galactic chemical evolution
  • Galactic chemodynamics
  • Galactic migration
  • The accreted halo
  • Stellar streams

This conference will use a hybrid format. For our Australian and New Zealand colleagues, we will be meeting in-person on the campus of the University of New South Wales in Sydney from 22 to 24 June 2021. For our international colleagues, it will highly unlikely that you will be able to travel to Australia, so you will be able to present and participate virtually. We will set aside time at the start and end of day for people to present via zoom at times friendly to your time zone. If the COVID-19 situation changes in Sydney, we will move the conference to fully online.

The 2021 GALAH Science Meeting will be free to attend. Please register using this form https://forms.office.com/r/eGMaEjVeZA to indicate how you will be attending and if you would like to present your work. If you wish to be considered for a presentation slot, please complete the form by Friday 21 May; otherwise, please complete the form by 11 June.

There will be some travel support available for people travelling from outside of NSW, with preference given to early career researchers presenting their work. We will also have free on-site childcare.

5. MAVIS Science Workshop (July 5-9, 2021, online)
We welcome the participation of the astronomical community to the 2021 MAVIS Science Workshop, to be held online during the week of July 5-9, 2021 (Detailed schedule to follow).

*REGISTRATION AND ABSTRACT SUBMISSION* (deadline May 30, 2021 – no registration fees): https://indico.ict.inaf.it/e/scimavis2021

MAVIS (MCAO Assisted Visible Imager and Spectrograph) is a forthcoming facility instrument for the ESO’s VLT AOF (Adaptive Optics Facility, UT4 Yepun) currently starting Phase B. MAVIS comprises two main parts: a Multi-Conjugate Adaptive Optics (MCAO) system, pushing AO into the visible on a large field of view and over a significant fraction of the sky; and its post-focal instrumentation, featuring a 30″x30″ imager, and a versatile integral field spectrograph (3” or 6” square field, R~5,000-15,000), both covering the visible part of the spectrum (370-1000nm) at the diffraction limit of the VLT. More information can be  found on MAVIS blog page (http://mavis-ao.org/mavis). With its unique parameter space, MAVIS is foreseen to cover broad science cases, from solar system objects to high redshift galaxies, as highlighted in the current MAVIS Science Case (https://arxiv.org/abs/2009.09242).

This workshop aims at bringing together the scientific community and discussing the key science cases where MAVIS 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 facilities such as ELTs and JWST. The workshop is an opportunity to engage the community and push forward the MAVIS project.

Format and Contributions
Given the current pandemic situation, the meeting will be fully online. To optimize the scientific outcome of the workshop and overcome limitations due to different time zones, the meeting will have pre-recorded contributions, available in advance, and live sessions mainly focused on discussion and interaction among participants.

As part of the registration, participants are strongly encouraged to provide a short abstract describing the science questions and topics they would like to address with MAVIS. The recorded talks will be informal, and can be up to 15 minutes in length. Shorter contributions are also welcomed. Live sessions will be held over a series of consecutive days, during an overlapping time window suitable for both east-coast Australia and Europe (most likely 6-9pm Australian Eastern Standard Time / 10am-1pm Central European Time).

A detailed schedule will be made available closer to the meeting, though we expect to discuss the following (non-exhaustive) list of topics:

  • Galaxies at high redshift
  • Evolution of galaxy structure
  • Interstellar medium of galaxies
  • Resolved stellar populations in galaxies
  • Intermediate Mass Black Holes
  • Supermassive Black Holes
  • Feedback mechanisms in galaxies
  • Star clusters across cosmic time
  • Stellar abundances
  • Circumstellar environments
  • Solar system bodies
  • Synergies with current and future facilities
