Stories of Open Science: Get involved as early as possible and contribute to others' projects - Dr. Leo Singer
No full textStories of Open Science: Get involved as early as possible and contribute to others’ projects. Dr. Leo Singer is a research astrophysicist at NASA’s Goddard Space Flight Center, working on the General Coordinates Network (GCN) and real-time analysis of the Laser Interferometer Gravitational-Wave Observatory (LIGO) data. He co-authored and co-maintains the LIGO/Virgo/KAGRA Public Alerts User Guide and is actively participating in the Astropy Project. “Don't assume that the tools you use are immutable. Get involved as early as possible because it takes years to get really good at contributing to other people's projects.
Kurt Singer Collection 1855-1953
No full textThe collection holds materials pertaining to the physician and musician Kurt Singer, including some of his musical writings; reviews of his books; correspondence, including letters from Max Friedlaender, Wilhelm Furtwaengler, and Siegfried Ochs, and others. Also included are papers of Kurt Singer’s father, the Hungarian-born Moritz Singer, who served as rabbi in Koblenz, including letters from Helmuth von Moltke and Duke Friedrich I of Baden; and documents from his studies at the universities of Berlin and Jena, including a thesis, as well as academic reports signed by Moritz Lazarus, Heymann Steinthal, and Theodor Mommsen.Born in Berent (now Koscierzyna, Poland) on October 11, 1885, Kurt Singer was a physician, conductor and musicologist, as well as music critic for the socialist newspaper Vorwaerts. From 1935 to 1938, he served as director of the Juedischer Kulturbund. He emigrated to Holland in 1939, and was deported to Theresienstadt in 1942. He died there in 1944.Photographs removed to Photograph CollectionBRUCKNER, ANTON, 1824-1896; FRIEDLÄNDER, MAX J., 1867-1958; FURTWÄNGLER, WILHELM, 1886-1954; OCHS, SIEGFRIED; MOLTKE, HELMUTH, GRAF VON, 1800-1891; SINGER, MORITZ; FRIEDRICH I, GRAND DUKE OF BADEN, 1826-1907; MOMMSEN, THEODOR, 1817-1903; STEINTHAL, HEYMANN, 1823-1899; LAZARUS, MORITZ, 1824-1903; BAB, JULIUS, 1880-1955; BLECH, LEO, 1871-1958; HIS, WILHELM; KOWALSKI, MAX, 1882-1956; KURTH, ERNST; SCHIKOWSKI, JOHN, 1867-; SZKELEY, JEHUDA.digitize

Data-driven expectations for electromagnetic counterpart searches based on LIGO/Virgo public alerts: cluster scripts
No full textSearches for electromagnetic counterparts of gravitational-wave signals have redoubled since the first detection in 2017 of a binary neutron star merger with a gamma-ray burst, optical/infrared kilonova, and panchromatic afterglow. Yet, one LIGO/Virgo observing run later, there has not yet been a second, secure identification of an electromagnetic counterpart. This is not surprising given that the localization uncertainties of events in LIGO and Virgo's third observing run, O3, were much larger than predicted. We explain this by showing that improvements in data analysis that now allow LIGO/Virgo to detect weaker and hence more poorly-localized events have increased the overall number of detections, of which well-localized, "gold-plated" events make a smaller proportion overall. We present simulations of the next two LIGO/Virgo/KAGRA observing runs, O4 and O5, that are grounded in the statistics of O3 public alerts. To illustrate the significant impact that the updated predictions can have, we study the follow-up strategy for the Zwicky Transient Facility. Realistic and timely forecasting of gravitational-wave localization accuracy is paramount given the large commitments of telescope time and the need to prioritize which events are followed up. We include a data release of our simulated localizations as a public proposal planning resource for astronomers.
This is an archive of the GitHub repository https://github.com/lpsinger/observing-scenarios-simulations, containing all of the scripts to reproduce the simulated gravitational-wave detections and localizations on a high performance computing cluster scheduled with HTCondor or PBS
