Conférences - Astronomie, astrophysique et cosmologie - États-Unis

The goal of the workshop is to bring together experts in turbulence from the perspectives of astrophysics, plasma physics, biology, mathematics, atmospheric sciences, and experimental design. We would like to promote an exchange of ideas, tools, and knowledge between different fields working on the still unsolved turbulence problem. The conference will include a mix of talks/lectures along with breakout sessions and discussion time.

We are pleased to announce the 2020 Sun-Climate Symposium, which is sponsored by the Sun-Climate Research Center, a joint venture between NASA GSFC and LASP at the University of Colorado. The format for this symposium consists of invited and contributed oral and poster presentations in several themed sessions. We encourage your participation and hope that you will share this announcement with colleagues.

Géophysique et géologie,    Météorologie et les changements climatiques

This conference will bring together experts in cosmology, particle physics, and fundamental theory to address how and when the universe thermalizes following inflation, and the associated particle physics and dark matter phenomenology. Important topics that will be covered include hidden sector model building in the LHC era, thermalization of the universe following inflation, possibilities of post-inflation cosmic history prior to nucleosynthesis, and associated experimental signatures. The conference aims to attract researchers in different areas to develop new directions in model building and establish new experimental paths for probing early universe cosmology and dark matter phenomenology.

This conference will synthesize recent observational discoveries of massive star clusters in nearby galaxies and the high-redshift universe. It will connect the observations to theoretical modeling of galaxy formation on large scales and star formation on small scales. The topics for discussion will include the efficiency of star cluster formation as a function of environment, and the origins of the cluster age and metallicity distributions. The meeting will aim to highlight the similarities and differences in star formation in low-redshift and high-redshift galaxies.

SPIE – The international society for optics and photonics

SPIE Astronomical Telescopes + Instrumentation is the most prestigious event for developers of ground- and space-based telescopes, the supporting technologies, and the latest instrumentation. Taking place every two years, the 2020 conference will be held in Yokohama, Japan. No other event in the astrophotonics industry draws the number of elite researchers, innovators, and companies, whose collective efforts push the frontiers of space and enable the building and maintaining of the important telescopes of the world.

Statistical estimates of nuclear reaction rates are essential ingredients for astrophysical model calculations, e.g. r-process nucleosynthesis in neutron star mergers, and nuclear applications, e.g. next generation nuclear reactor performance. Rate calculations require experimental or theoretical constraints for nuclear properties such as level densities (temperature), gamma-strength functions, particle optical potentials, and level spin distributions. Recently major advances have been made experimentally constraining the statistical properties of nuclei, particularly off the valley of beta-stability, while systematic studies have identified critical data needs for astrophysics and applications. As such, the time is ripe to “take the temperature” of the field of statistical nuclear physics to share recent advances and promising opportunities.

NASA

The Sagan Exoplanet Summer Workshops are held annually and provide opportunities for students, postdocs, and researchers to learn about the engineering and scientific application of exoplanet-related techniques used in NASA's Exoplanet Exploration Program.

This kick-off workshop will seek to provide an overview of both the state-of-the-art and open challenges drawing from multiple themes (theory, analysis of the equations, computation, and data analysis) within the broad context of Einstein's general relativity theory.

University of Arizona, Department of Astronomy

This is a special symposium in honor of Marc Aaronson, who was a postdoc at Steward Observatory starting in 1977 and an Associate Professor starting in 1983. His astronomical research focused on many of the most important problems of observational cosmology: the cosmic distance scale, the age of the Universe, the large-scale motion of matter, and the distribution of invisible mass in the Universe.

The circumgalactic medium (CGM) can be viewed as an atmosphere that surrounds a galaxy and sustains star formation within it. Much of what we know about the CGM has come from absorption-line spectroscopy, mainly in the UV band, of gas at temperatures below the galaxy's virial temperature. A comparable amount of hotter gas, closer to the virial temperature, may also be present but has been harder to detect. If it is there, then the properties of the cooler clouds and the hotter ambient medium are likely to be complementary, deeply interwoven, and physically complex. It follows that the physics of cosmic rays, magnetic fields, turbulent mixing layers, conductive interfaces, and shocks may then play a leading role in setting the fate of the multiphase CGM. This conference will examine the evidence for a virial-temperature component along with the observations capable of revealing its properties and its relationship to the cooler components. Probes that complement UV absorption-line observations will be emphasized, including X-ray emission and absorption, UV and optical emission, Sunyaev-Zel'dovich probes, Fast Radio Bursts, and signposts of non-thermal particle acceleration.

Astrometric, photometric and spectroscopic all-sky surveys provide the first complete, unbiased view of the Galactic population of the most abundant type of stellar remnants: white dwarfs. This wealth of observational data provides an array of opportunities to use white dwarfs as probes of a wide range of astrophysics, including the formation and evolution of stars and planets, the star formation rate of the Galaxy, and the populations of low-frequency gravitational wave sources and progenitors of thermonuclear supernovae. These applications require improved models of these electron-degenerate stars, which in turn rely on developments in the relevant input physics, including equations of state and opacities. This conference will provide a joint platform for experts in the observational and theoretical study of white dwarfs, scientists working on the underlying fundamental physics, and astronomers using white dwarfs as diagnostic tools to gain a panoramic overview of the state-of-the-art, to identify remaining limitations of the current models, and to explore novel scientific opportunities arising from the new data.
