Beginning early science operations over a decade ago in 2011, the Atacama Large Millimeter/submillimeter Array (ALMA) is now in the midst of Cycle 9 observations. Over the past ten years, ALMA has provided unprecedented sensitivity, image fidelity, and resolution at millimeter and submillimeter wavelengths, supporting the research interests of more than 10,000 PIs and co-Is. From solar system objects to the earliest galaxies, ALMA observations have produced breathtaking images and opened new discovery space. ALMA data have been published in over 2900 refereed publications.
This AAS 241 Special Session will describe for the membership ALMA news, capabilities, and expectations for ALMA performance and science in the next few years and plans for its upgrade in the 2030 timeframe. In that period, ALMA will complete its frequency coverage of the millimeter window. ALMA's bandwidth will be increased to enhance continuum sensitivity even as its line sensitivity is increased via receiver upgrades, an upgraded correlator and upgrades of the systems connecting them. Higher resolution imaging is being explored, both on the exceptional site and as part of the extremely long baseline imaging arrays.
The session also features a set of science talks presenting a wide range of recent, exciting ALMA results and highlights the support available to the community from the North American ALMA Science Center (NAASC) at the National Radio Astronomy Observatory (NRAO).
