Abstract

We describe a dynamic science portal called the GROWTH Marshal that allows time-domain astronomers to define science programs; program filters to save sources from different discovery streams; coordinate follow-up with various robotic or classical telescopes; analyze the panchromatic follow-up data; and generate summary tables for publication. The GROWTH marshal currently serves 137 scientists, 38 science programs, and 67 telescopes. Every night, in real time, several science programs apply various customized filters to the 10^5 nightly alerts from the Zwicky Transient Facility. Here, we describe the schematic and explain the functionality of the various components of this international collaborative platform.

This work was supported by the GROWTH (Global Relay of Observatories Watching Transients Happen) project funded by the National Science Foundation Partnership in International Research and Education program under grant No. 1545949. GROWTH is a collaborative project between the California Institute of Technology (USA), Pomona College (USA), San Diego State University (USA), the Los Alamos National Laboratory (USA), the University of Maryland College Park (USA), the University of Wisconsin–Milwaukee (USA), the Tokyo Institute of Technology (Japan), the National Central University (Taiwan), the Indian Institute of Astrophysics (India), the Inter-University Center for Astronomy and Astrophysics (India), the Weizmann Institute of Science (Israel), The Oskar Klein Centre at Stockholm University (Sweden), and Humboldt University (Germany). Tested with observations obtained with the Samuel Oschin Telescope 48-inch and the 60-inch Telescope at the Palomar Observatory as part of the Zwicky Transient Facility project. Major funding has been provided by the U.S National Science Foundation under grant No. AST-1440341 and by the ZTF partner institutions: the California Institute of Technology, the Oskar Klein Centre, the Weizmann Institute of Science, the University of Maryland, the University of Washington, Deutsches Elektronen-Synchrotron, the University of Wisconsin–Milwaukee, and the TANGO Program of the University System of Taiwan. We thank I. Arcavi for valuable contributions to the predecessor of this system, the Palomar Transient Factory marshal system.
