Taking the Temperature: Statistical Nuclear Physics for Astrophysics and Applications
13 jul 2020 - 16 jul 2020 • Athens, Ohio, États-Unis
Organisateur:
Ohio University in Athens
Résumé:
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.

GMTCSM8 — GMT Community Science Meeting: Black Holes at all Scales
09 sep 2020 - 11 sep 2020 • Sedona, AZ, États-Unis
Organisateur:
GMTO Corporation
Résumé:
Black holes are among the most extraordinary objects in the Universe. Pivotal new results include the detection of gravitational radiation from merging black holes and the imaging of event horizon scale regions. These discoveries have revolutionized the field while demonstrating how much remains to be learned about black hole demographics, formation and evolution, and interactions with their environment. This conference will focus on dynamics as a way to probe and learn about black holes across all mass scales, and topics will include the environment around Sgr A*, black hole mass measurements, demographics, rates for gravitational wave events, accretion disk dynamics around single and binary black holes, and tidal disruption events. Experts across this wide range of subfields will be brought together to canvass observational and theoretical progress, highlight key unanswered questions, and motivate future directions, particularly in the era of extremely large telescopes.

Résumé:
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.

Aaronson Symposium: Galactic Dynamics with Resolved Stars
21 sep 2020 - 23 sep 2020 • Tucson, Arizona, États-Unis
Organisateur:
University of Arizona, Department of Astronomy
Résumé:
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.

Multiwavelength Probes of Galactic Atmospheres
25 jan 2021 - 28 jan 2021 • UC Santa Barbara, États-Unis
Organisateur:
Kavli Institute for Theoretical Physics (KITP)
Résumé:
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.

White Dwarfs from Physics to Astrophysics
29 mar 2021 - 01 avr 2021 • UC Santa Barbara, États-Unis
Organisateur:
Kavli Institute for Theoretical Physics (KITP)
Résumé:
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.
