National Radio Astronomy Observatory

Dark skies and remote sites have attracted world-class astronomical facilities to the Southwest and supported a wide range of research since the mid-1900s. Regional achievements span areas in both science and technology including optical and radio interferometry, as well as new understanding of solar physics, planetary science, star and galaxy formation and evolution, and the creation and evolution of our universe. To support the network of scientific research in the Southwest and encourage interdisciplinary discussions, the National Radio Astronomy Observatory (NRAO) and New Mexico Tech are sponsoring the 35th Annual New Mexico Symposium on Friday, 21 February 2020, at the NRAO Science Operations Center (SOC) in Socorro, NM.

After a few years hiatus, the GCGM returns! The 9th Gulf Coast Gravity Meeting will be held at the University of Mississippi in Oxford, MS, on March 13 and 14, 2020. In keeping with its tradition, this will be an open, relaxed, and informal conference. We are inviting researchers and students interested in all areas of gravitational physics: classical and quantum gravity, general relativistic astrophysics and cosmology, quantum cosmology, gravitational waves, and experimental gravity. Because this is a regional meeting, many attendees will be from the southeastern United States, but all are welcome.

Whenever an observation of an astrophysical source must be converted from instrumental values to physical units, we use flux calibration. As new questions are formulated and new capabilities become available, the requirements on the precision and accuracy of flux calibration increase. Once upon a time, 10% was considered good enough, but today, 1% is demanded, which advances in technology and computation power now enable. This workshop addresses current issues in flux calibration for the new generation of telescopes and for multi-wavelength science. In addition, the workshop honors Ralph Bohlin's seminal contributions over 40 years, particularly the development of CALSPEC, the database of spectrophotometric standards used by much of the astronomical research community.

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.

The 17th Synthesis Imaging Workshop will be held on 13 - 20 May 2020 at NRAO and New Mexico Institute of Mining and Technology (NMT) in Socorro, New Mexico. The workshop will comprise of a week of lectures on aperture synthesis theory and techniques, and practical tutorials demonstrating data collection, calibration, and imaging of various types of data, including new data from the Jansky VLA, ALMA and the VLBA. The workshop will be delivered at a level appropriate for graduate students in astrophysics.

The week-long school will focus on computational and theoretical large-scale structure, while allowing in-depth exploration of how current research tests theory with data. The school will be hands-on and partly computational, so that the participants acquire concrete practical skills in modeling data (and theory). Each lecturer will deliver ~4-5 hrs of lectures; some of that time may be devoted to numerical exercises/calculations. Confirmed lecturers include Ami Choi (Ohio State), Tim Eifler (Arizona), Tesla Jeltema (Santa Cruz), Adrian Liu (McGill), Will Percival (Waterloo), Mark Vogelsberger (MIT), and Joe Zuntz (Edinburgh).

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.

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.

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.
