1. AGN and Polarimetry conference (Nov. 2-4th 2020, Strasbourg, France)
Title: Towards a panchromatic understanding of the polarization of Active Galactic Nuclei
Place and dates: Strasbourg, France, Nov. 2-4th, 2020

Website: https://polagn.astro.unistra.fr/

Rationale: Among all the observational techniques used in astronomy, polarimetry has been fundamental to determine the nature, geometry and physical mechanisms of Active Galactic Nuclei (AGN). Polarimetry, either using broadband filters, spectroscopy, timing information, or imaging capabilities, has made history by unveiling the importance of the nucleus inclination in the vast zoology of quasi-stellar objects. Polarimetry revealed the physical origin of the featureless continuum, constrained the magnetic field intensity and topology in jets, detected strong and asymmetrical outflows from the inner AGN region, exposed the alignment of quasar polarization with large-scale structures and continues providing new information on the morphology and chemistry of extra-galactic dust. However, despite these great advances, the panchromatic polarization of AGN is far from being understood. The principal reason is the fact that radio measurements are restricted to narrow bands, infrared polarimeters are scarce, and high energy data (far ultraviolet, X- and gamma-rays) are simply missing.
The upcoming era of gigantic radio arrays (SKA, HERA, ngVLA), millimeter dishes (ALMA, EHT, AtLAST), large-class ground-based and space born telescopes (JWST, LSST, ELT, SPICA) and high energy polarimeters in space (IXPE, eXTP, LUVOIR/POLLUX) indicates that this is the perfect time to meet and gather all the recent AGN polarization discoveries. This conference is meant to summarize our current understanding of the panchromatic polarization signatures in AGN from observations and modeling, determine the best strategy to fill our knowledge gaps, learn about the new generation of instruments that could be beneficial to the field and make a strong case for the inclusion of polarimeters in any new observatory.

Invited speakers:
Damien Hutsémekers (University of Liege)
Svetlana Jorstad (Boston University)
Makoto Kishimoto (Kyoto Sangyo University)
Ivan Marti-Vidal (University of Valencia)
Giorgio Matt (University of Roma III)
Coralie Neiner (LESIA laboratory, Paris-Meudon Observatory)

Dragana Ilic (University of Belgrade)
Enrique Lopez Rodriguez (SOFIA Science Center)
Frédéric Marin (Astronomical Observatory of Strasbourg, chair)
Cristina Ramos Almeida (Instituto de Astrofísica de Canarias)
Dominique Sluse (University of Liege)

Katharina Lutz (Astronomical Observatory of Strasbourg)
Rashi Jain (Astronomical Observatory of Strasbourg)
Thomas Lizée (Astronomical Observatory of Strasbourg)
Yelena Stein (Astronomical Observatory of Strasbourg)

General information:
This three-days conference will be held at the University of Strasbourg, France, from Monday the 2nd (morning) to Wednesday the 4th (afternoon), in November 2020. An invited speaker will give a review talk at the beginning of each half-a-day session, followed by shorter contributed talks. Posters are welcomed. The theme of each session will be given after receiving all the presentation proposals. We strongly encourage talks on current and forthcoming telescopes and satellites that will provide polarimetric data. Talks on the polarization from AGN-related physics and objects (particle production in jets, non-active galactic nuclei and smaller-scale black holes) are also greeted. Social events around Alsatian cuisine and wine are planned. Finally, depending on the pandemic situation, online talks will be arranged for speakers who will not be able to travel to France.

/This conference is funded thanks to the French National Programs for astrophysics, in particular by the Programme National Cosmology et Galaxies (PNCG) and the Programme National des Hautes Energies (PNHE) of CNRS/INSU with INP and IN2P3, co-funded by CEA and CNES/

2. Réunion groupes de travail GdR RESANET/OG (9-10 june 2020, Caen) REMOTELY

In view of the current situation, the meeting of the working groups « Nuclear astrophysics » of GdR RESANET and « Neutron stars and supernovae » of GdR Ondes Gravitationnelles planned for 9-10 june in Caen, will take place remotely.

Matteo Barsuglia (APC), Nicolas Chamel (ULB) and Francesco Nitti (APC) have agreed to present webinars with time for discussion.
The links will be sent to all registered participants and the mailing lists of both GdRs.

3. Science with the Hubble and James Webb Space Telescopes VI (Stockholm, Sweden) POSTPONED
The organizers of the Science with the Hubble and James Webb Space Telescopes VI have decided to postpone the conference to 2021 because of the continued disruption to travel caused by COVID-19. ​​

The conference will still be held in person at the Hotel Hasselbacken in Stockholm, at a date to be announced in October 2020.

If you need to cancel your conference registration, contact the registration office and your payment will be refunded.
If you need to cancel your reservations at the Hotel Hasselbacken,  please do so through their website.
You will need your reservation number from the original confirmation email to complete the cancellation.
We will publish the new dates in October, and at that point we will ask you to confirm whether or not you will still be able to attend the conference next year.

4. Postdoctoral Scholar Position for the Simons Observatory at the University of Pennsylvania

Deadline: Aug 1, 2020

The Experimental Cosmology Group at the University of Pennsylvania invites applicants for a postdoctoral scholar position working on Simons Observatory (http://simonsobservatory.org) to study the cosmic microwave background (CMB). The start date is flexible, but nominally, the fall of 2020. The Simons Observatory is a world-leading collaboration in CMB is undertaking both cutting-edge CMB science and technical development crucial toward the next-generation CMB-S4 experiment. Successful candidates will be involved in the design, construction and execution of the Simons Observatory. In particular, the Penn team will be commissioning the Large Aperture Telescope Receiver (LATR) and the six-meter diameter Large Aperture Telescope (LAT). The LATR is the largest CMB camera ever constructed and its integration requires a broad set of skills including cryogenics, detectors, optics, mechanical design, software, and electronics. Strong organizational and interpersonal skills are also important aspects of working in a collaboration like the Simons Observatory. Travel to Germany for the LAT integration and the high mountains of Chile may be required. Applicants with a broad spectrum of skills and experience are encouraged to apply.

Applicants should have a Ph.D. in Physics or Astronomy before the start date of the position. They should have at least one year of relevant research experience as a graduate student or as a postdoc. Applicants should send a cover letter and cv to Mark Devlin (devlin@physics.upenn.edu) as well as arranging for three letters of recommendation.

5. PhD in Napoli. Scuola Superiore Meridionale.

Deadline: June 30, 2020

The Scuola Superiore Meridionale (SSM) is opening this year, with a PhD program in Cosmology, Space Science, and Space Technology. The school offers a stimulating environment with special courses and the use of English as standard language. Successful candidates will have an individual scholarship and can choose an advisor among the members of the School itself, and of the Physics Department of Università di Napoli.

Details can be found here

Application procedure is light, and deadline is June 30.
