ngVLA Summer Short Talk Series

June 25th, 2020

A weekly virtual ngVLA Summer Short Talk Series ran 25 June–10 September 2020. The recorded presentations and Q&A exchanges discussed key science questions and their connection to present and future observing facilities at all wavelengths. The presenter lineup was organized by the ngVLA Science Advisory Council, led by co-chairs Alberto Bolatto (Maryland) and Andrea Isella (Rice). A total of 768 individuals from 47 countries attended one or more presentations. The average attendance at each meeting included over 200 participants, ranging between 150-380, and represented well over 100 institutions. A large percentage of participants were graduate students.

ngVLA Science Book Published

December 21st, 2018

With nearly 90 chapters (850+ pages) from 285+ authors, this volume highlights key areas of astrophysics that are ripe for major breakthroughs and underscores the broad U.S. and international support for pursuing a next-generation Very Large Array (ngVLA). While this published volume will serve as a critical snapshot for the ngVLA project status and a vision for the ngVLA transformational science, we envisage this science book as a living document that will be periodically updated through the initiation of construction.

First Draft of the ngVLA Science Book Released

June 22nd, 2018

With 50 (refereed) contributions received to date by nearly 200 unique authors, and more than 10 still in prep., this volume highlights key areas of astrophysics that are ripe for major breakthroughs and clearly underscores the broad U.S. and international support that exists for pursuing a next-generation Very Large Array in the next decade. The science book will continue to be updated over the summer, with contributions being accepted by our Science Advisory Committee until September 1, 2018 in the hope that community members will consider authoring additional chapters, especially for areas that appear to be missing in the current draft.
