E04.00001: Recent developments in gravitational-wave astronomy Invited Speaker: Joseph Romano In this talk, I briefly describe recent developments in gravitational-wave astronomy, touching on searches using ground-based interferometers (e.g., LIGO, Virgo, ...), space-based interferometers (LISA), and pulsar timing arrays (e.g., NANOGrav). Where possible, I discuss synergies between the various searches. [Preview Abstract] |

E04.00002: The Next-Generation Very Large Array (ngVLA) Invited Speaker: Joan Wrobel The ngVLA is a versatile interferometric array envisaged to operate as a facility of the U.S. National Science Foundation (NSF), starting in the 2030s. It will deliver an order of magnitude improvement in both sensitivity and angular resolution compared to existing and planned facilities at frequencies spanning 1.2 - 116 GHz. The ngVLA will tackle a vast range of key, outstanding questions in modern astrophysics by simultaneously delivering the capability to: unveil the formation of Solar System analogs on terrestrial scales; probe the initial conditions for planetary systems and life with astrochemistry; chart the assembly, structure, and evolution of galaxies from the first billion years to the present; use pulsars in the Galactic Center as fundamental tests of gravity; and understand the formation and evolution of stellar and supermassive black holes in the era of multi-messenger astronomy. Being highly synergistic with its contemporary facilities in space, on the ground, or underground, the ngVLA will maximize the scientific returns on additional investments made by funding agencies in the U.S. and abroad.

E04.00003: Thirty-Meter Class Telescopes and Texas’ Opportunity Invited Speaker: Angela Speck In the coming decade, ground based astronomy will experience a revolution with the advent of the 30m class of telescopes. The US ELT Program was recently launched to provide a coordinated system for US astronomers to participate in the transformative capabilities that these capabilities will afford. Texas has an important position to play in this arena, which is discussed in this presentation. \\ \\ In collaboration with: Chris Packham, UTSA [Preview Abstract] |

E04.00004: Next generation astronomical observatories and the Maunakea Spectroscopic Explorer Invited Speaker: Jennifer Marshall The next decade will see great advances in ground-based astronomy's spectroscopic observing capabilities: facilities that are under development today will have larger collecting areas and greater spectroscopic multiplexing capabilities than ever before, and are sure to revolutionize the scientific productivity of our field. In this talk I will review existing and near-future observatories that will lay the scientific and technological groundwork for next-generation projects such as the Maunakea Spectroscopic Explorer project, a massively multiplexed spectroscopic facility currently under development in Hawaii that features an 11.25m diameter primary mirror which feeds 4,332 fibers and a suite of low- and high-resolution spectrographs.

E04.00005: High Energy Astrophysics Missions Invited Speaker: David Pooley X-ray and gamma-ray observations of the Universe are necessary to understand the makeup and workings of the cosmos. Much of the baryonic matter in the Universe is primarily observable in X-rays, and the sites of the most energetic processes are observable in X-rays and gamma-rays. Over the past twenty years, groundbreaking discoveries have been made by large missions like the {\it Chandra X-ray Observatory}, {\it XMM-Newton} observatory, and {\it Fermi Gamma-ray Space Telescope}, as well as medium and small class missions like the {\it Neil Gehrels Swift Observatory}, the {\it Nuclear Spectroscopic Telescope Array (NuSTAR)}, {\it Hitomi}, and {\it Suzaku}. With the groundwork laid by the above missions, we are poised to address fundamental questions about the cosmos. I will discuss what can be learned from upcoming and proposed missions like the Athena X-ray Observatory, the X-ray Imaging and Spectroscopy Mission, the extended Roentgen Survey with an Imaging Telescope Array, the Imaging X-ray Polarimetry Explorer, the Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays, and the Lynx X-ray Observatory. I will focus in particular on Lynx, a NASA flagship mission concept, with the power to transform our understanding of the cosmos through unprecedented X-ray vision into the otherwise invisible Universe. It is designed to pursue three fundamental science pillars: (1) seeing the dawn of black holes; (2) revealing what drives galaxy formation and evolution; and (3) unveiling the energetic side of stellar evolution and stellar ecosystems.
