3. The 32nd Texas Symposium on Relativistic Astrophysics (11-15 Dec 2023, Shanghai, China)

Since 1963, the Texas Symposium on Relativistic Astrophysics has been one of the most important international conferences in astronomy and physics.  Traditionally, it moves around the globe and takes place in different cities every two years.

The 32nd Texas Symposium on Relativistic Astrophysics will take place in Shanghai, China, from December 11 to 15,2023. It will be hosted by Tsung-Dao Lee Institute, Shanghai Jiao Tong University.

https://indico-tdli.sjtu.edu.cn/event/1582/
Shanghai, situated on the estuary of Yangtze River, serves as the most influential economic, financial, international trade, and cultural center in East China.  It is also a popular destination for travelers seeking to experience the country’s dynamic development.  In addition to its modernization, the city’s multicultural flair endows it with a unique charm. New skyscrapers and old Shikumen together draw the skyline of the city. Western customs and Chinese traditions intertwine, making any visit to Shanghai a memorable experience.

Tsung-Dao Lee Institute (TDLI), initiated by Tsung-Dao Lee, a prominent Chinese-American physicist and Nobel laureate in Physics, was established in 2016 with strong support from various Chinese government agencies. The goal of TDLI is to develop into a top-level physics-astronomy research institute in the world, and to boost research and develop talents in basic sciences in China. Professor Frank Wilczek was the founding director, and Professor Jie Zhang is the current director.

The symposium will cover all major topics on high-energy and particle astrophysics, cosmology and relativity. It will include morning plenary sessions and afternoon parallel sessions which will function as mini-symposia in each sub-field. The plenary sessions will consist of 30-45 min review talks. The afternoon sessions will feature oral talks (about 20-30 min) and poster contributions. 

We look forward to welcoming hundreds of international astronomers and physicists to Shanghai in December 2023!

4. Understanding cosmological observations (23 Jul – 5 Aug 2023, Benasque, Spain)

A new wave of data is arriving from large-scale structure observations and high-sensitivity CMB polarization measurements. This workshop will focus on the data and theoretical modelling required to robustly understand the new observations as non-linear and foreground physics becomes increasingly important, and on the range of theoretical models that could explain the data and be empirically tested in the next decade.

The meeting takes place in a particularly beautiful and inspiring atmosphere below the peak of Aneto, the highest point in the Pyrenees. The program will consist mainly of a few lectures and discussion sessions, leaving plenty of time in the afternoon for interactions and research, as well as for mountain hiking. There will be plenty of opportunity for people to organise more specialized discussions where they can also present contributed talks.

In the evening, the village offers a warm and relaxing atmosphere with good and mostly inexpensive bars and restaurants. The Centre is equipped with facilities such as library, wifi, blackboards, discussion rooms and coffee lounges. Participants will get a desk in a shared office. All participants will be accommodated in hotel rooms or in nice apartments managed by the Conference center (1, 2 or 3 bedroom apartments available, for prices ranging approximately from about 400 to 700 euros/week , which can be shared between participants). There will be a registration fee (by default 350 euros for the two weeks, including bus transfer from Barcelona, reception and coffee breaks), but we may be able to subsidise a small number on request. Please note that the number of participants is limited, so unfortunately we usually cannot accept everyone who would like to come. We ask interested participants to (pre)register now, but payments will only be due after final confirmation of places, which will be done after May 20th, 2023.

Plenary Speakers:

  • Alex Amon
  • Florian Beutler
  • Kim Boddy
  • Tamara Davis (TBC)
  • Silvia Galli
  • Oliver Hahn
  • Lam Hui
  • Tanvi Karwal
  • Tania Regimbau
  • Fabian Schmidt

5. Cosmology from Home (3-14 July 2023, online)

We are very happy to announce the fourth annual Cosmology from Home conference, which will be held from 3 July – 14 July 2023.

Cosmology from Home is an online cosmology conference with a novel format aimed at bringing the real-world workshop experience into the online domain. The format includes the use of pre-recorded talks, and a combination of asynchronous and scheduled live discussions. A permanently-available and freely-navigated discussion space also facilitates ongoing and organic, face-to-face discussions. The conference will bring together cosmologists from around the world to discuss the current state of cosmology at the interface of theory and observations.

Registration is now open: https://www.cosmologyfromhome.com/registration. (Note: there will be a limited number of participants.)

Abstract submission will close on 23 May 2023, 23:59 UTC.

6. 1st Training School of the COST Action CA21106, Cosmic WISPers in the Dark Universe (11-14 September 2023, Lecce, Italy)
The European COST Action CA21106 “Cosmic WISPers in the Dark Universe: Theory, astrophysics and experiments” is an initiative funded by the COST Association, whose goal is to study axions and other very weakly interacting slim particles (WISPs) emerging in several extensions of the Standard Model of Particle Physics. Searches for WISPs are strongly motivated by our attempts to understand the nature of the dark matter and puzzling astrophysical and particle physics observations.
https://agenda.infn.it/e/CA21106_Training_School

The deadline for application is 31st May.

The COST Action CA21106 1st Training School will be held in Lecce (Italy). The goal is to start training a generation of young scientists in the interdisciplinary expertise on WISPs, ranging from theoretical and experimental approaches to multi-messenger astroparticle physics and cosmology. For this purpose, the Training School will offer lectures from experts on different aspects of WISPs physics. The School is aimed at PhD students, as well as early-career postdocs.

We plan to provide financial support up to 30 participants interested in attending the School.
In order to apply for this grant, you have to check the eligibility conditions and follow the procedure indicated on the webpage.
You will receive confirmation of the financial support just after the deadline. Since Lecce is a touristic city it is recommended to book your hotel in advance.

8. CMB foregrounds postdoc at Manchester
Deadline: extended to 3rd May
The Jodrell Bank Centre for Astrophysics (JBCA), part of the department of Physics & Astronomy, seeks a Post-Doctoral Research Associate(s) to work in the area of CMB foregrounds. Manchester has significant involvement in several leading CMB and foreground experiments including the C-Band All-Sky Survey (C-BASS), Simons Observatory (SO), and JAXA’s LiteBird space mission. We are leading several areas, with a particular emphasis on astrophysical foregrounds and systematic effects mitigation. The focus will be on understanding and quantifying foregrounds emission using the latest data (e.g., C-BASS and COMAP), both for CMB foreground removal and for understanding the interstellar medium (e.g., emission mechanisms, Galactic structure, Galactic magnetic field, star formation). Ideally, we are looking for someone who crosses the divide between CMB cosmology and astrophysical foregrounds research. In particular, we are looking to develop a foregrounds pipeline for the LiteBird mission. The successful candidate(s) will have the opportunity to work on one or more of our projects, collaborating with our other postdocs/students, depending on their interest and skills.

9. Several Postdoc positions related to cosmology and/or astrostatistics + 1 data scientist (IRFU/DAp-AIM, CEA Saclay)

We have the following open positions:

More Information: 
http://www.cosmostat.org/jobs

And also a 18 months contract for a Data Scientist:

Euclid is a satellite, which will be sent in July, so the objective is cosmology, in particular from the weak lensing probe. The very precise knowledge of the response of the Euclid telescope (Euclid Point Spread Function, PSF) is the key challenge for the success of the mission.

The position concerns the reconstruction of the PSF.
We have developed a code in TensorFlow which seems to work well, but we would like to do some deep performance studies, and test the quality of the reconstruction considering many systematic effects. It is therefore a Data Scientist position, with a person capable of understanding our algorithms, carrying out performance studies, and writing up the results.
A scientific article may possibly be considered.

The aspects of the position are therefore:

  • Understand the principles of PSF reconstruction, learning to use codes, use of super-computers.
    See the paper: https://ui.adsabs.harvard.edu/abs/2023InvPr..39c5008L/abstract
  • Run numerical simulations.
  • From the simulations, reconstruct the PSFs.
  • Evaluate the quality of the reconstructions
  • Writing the results.
