Since first light in March 2018, ZTF has taken prompt observations for 24 high-quality neutrino alerts from the IceCube Neutrino Observatory, with a median latency of 12.2 hours from initial neutrino detection. From two of these campaigns, we have already reported tidal disruption event (TDE) AT2019dsg and likely TDE AT2019fdr as probable counterparts, suggesting that TDEs contribute >7.8% of the astrophysical neutrino flux. We here present the full results of our program through to December 2021. No additional candidate neutrino sources were identified by our program, allowing us to place the first constraints on the underlying optical luminosity function of astrophysical neutrino sources. Transients with optical absolutes magnitudes brighter that -21 can contribute no more than 87% of the total, while transients brighter than -22 can contribute no more than 58% of the total, neglecting the effect of extinction. These are the the first observational constraints on the neutrino emission of bright populations such as superluminous supernovae. None of the neutrinos were coincident with bright optical AGN flares comparable to that observed for TXS 0506+056/IC170922A, suggesting that most astrophysical neutrinos are not produced during such optical flares. We highlight the outlook for electromagnetic neutrino follow-up programs, including the expected potential for the Rubin Observatory.", "doi": "10.48550/arXiv.2203.17135", "publisher": "arXiv", "publication_date": "2022-03-31" }, { "id": "authors:wks9q-eg059", "collection": "authors", "collection_id": "wks9q-eg059", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20220526-173258641", "type": "monograph", "title": "The Final Season Reimagined: 30 Tidal Disruption Events from the ZTF-I Survey", "author": [ { "family_name": "Hammerstein", "given_name": "Erica", "orcid": "0000-0002-5698-8703", "clpid": "Hammerstein-Erica" }, { "family_name": "van Velzen", "given_name": "Sjoert", "orcid": "0000-0002-3859-8074", "clpid": "van-Velzen-Sjoert" }, { "family_name": "Gezari", "given_name": "Suvi", "orcid": "0000-0003-3703-5154", "clpid": "Gezari-Suvi" }, { "family_name": "Cenko", "given_name": "S.

While the number of observed TDEs has grown thanks to the emergence of wide-field surveys in the past few decades, questions regarding the nature of the observed optical, UV, and X-ray emission remain. We present a uniformly selected sample of 30 spectroscopically classified TDEs from the Zwicky Transient Facility Phase I survey operations with follow-up Swift UV and X-ray observations. Through our investigation into correlations between light curve properties, we recover a shallow positive correlation between the peak bolometric luminosity and decay timescales. We introduce a new spectroscopic class of TDE, TDE-featureless, which are characterized by featureless optical spectra. We recover a difference between the light curve timescales of the four TDE classes, with TDE-H+He having longer rise times. The new TDE-featureless class shows larger peak bolometric luminosities, peak blackbody temperatures, and peak blackbody radii. We examine the differences between the X-ray bright and X-ray faint populations of TDEs in this sample, finding that X-ray bright TDEs show longer decay timescales than the X-ray faint sub-sample. We present a scheme for classifying the shapes of the optical light curves, finding that TDEs with \"structured\" light curves have significantly less massive host galaxies than other types of TDEs. This sample of optically selected TDEs is the largest sample of TDEs from a single survey yet, and the systematic discovery, classification, and follow-up of this sample allows for robust characterization of TDE properties, an important stepping stone looking forward toward the Rubin era.", "doi": "10.48550/arXiv.2203.01461", "publisher": "arXiv", "publication_date": "2022-03-03" } ]
