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:1nqj8-pm768", "collection": "authors", "collection_id": "1nqj8-pm768", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20211130-215814897", "type": "monograph", "title": "Establishing accretion flares from massive black holes as a major source of high-energy neutrinos", "author": [ { "family_name": "van Velzen", "given_name": "S.", "orcid": "0000-0002-3859-8074", "clpid": "van-Velzen-Sjoert" }, { "family_name": "Stein", "given_name": "R.", "orcid": "0000-0003-2434-0387", "clpid": "Stein-Robert-D" }, { "family_name": "Gilfanov", "given_name": "M.", "clpid": "Gilfanov-Marat" }, { "family_name": "Kowalski", "given_name": "M.", "orcid": "0000-0001-8594-8666", "clpid": "Kowalski-Marek" }, { "family_name": "Hayasaki", "given_name": "K.", "clpid": "Hayasaki-K" }, { "family_name": "Reusch", "given_name": "S.", "orcid": "0000-0002-7788-628X", "clpid": "Reusch-Simeon" }, { "family_name": "Yao", "given_name": "Y.", "clpid": "Yao-Y" }, { "family_name": "Garrappa", "given_name": "S.", "orcid": "0000-0003-2403-4582", "clpid": "Garrappa-Simone" }, { "family_name": "Franckowiak", "given_name": "A.", "orcid": "0000-0002-5605-2219", "clpid": "Franckowiak-Anna" }, { "family_name": "Gezari", "given_name": "S.", "orcid": "0000-0003-3703-5154", "clpid": "Gezari-Suvi" }, { "family_name": "Nordin", "given_name": "J.", "orcid": "0000-0001-8342-6274", "clpid": "Nordin-Jakob" }, { "family_name": "Fremling", "given_name": "C.", "orcid": "0000-0002-4223-103X", "clpid": "Fremling-Christoffer" }, { "family_name": "Sharma", "given_name": "Y.", "orcid": "0000-0003-4531-1745", "clpid": "Sharma-Yashvi" }, { "family_name": "Yan", "given_name": "L.", "orcid": "0000-0003-1710-9339", "clpid": "Yan-Lin" }, { "family_name": "Kool", "given_name": "E.

Here we present a unified explanation for the latter two of these sources: accretion flares that reach the Eddington limit. A signature of these events is a luminous infrared reverberation signal from circumnuclear dust that is heated by the flare. Using this property we construct a sample of similar sources, revealing a third event coincident with a PeV-scale neutrino. This sample of three accretion flares is correlated with high-energy neutrinos at a significance of 3.7 sigma.

This is one of the largest systematically selected samples of day-timescale transients, and the first with spectroscopic classifications. Most can be classified as core-collapse supernovae (SNe), and we identify several predominant subtypes: (1) subluminous Type IIb or Type Ib SNe; (2) luminous Type Ibn or hybrid IIn/Ibn SNe; and (3) radio-loud, short-duration luminous events similar to AT2018cow. We conclude that rates quoted in the literature for rapidly evolving extragalactic transients are dominated by the subluminous events (mostly Type IIb SNe). From our spectroscopic classifications and radio, X-ray, and millimeter-band upper limits, we are motivated to consider the AT2018cow-like objects a distinct class, and use ZTF's systematic classification experiments to calculate that their rate does not exceed 0.1% of the local core-collapse SN rate, in agreement with previous work. By contrast, most other events are simply the extreme of a continuum of established SN types extending to ordinary timescales. The light curves of our objects are very similar to those of unclassified events in the literature, illustrating how spectroscopically classified samples of low-redshift objects in shallow surveys like ZTF can be used to photometrically classify larger numbers of events at higher redshift.", "doi": "10.48550/arXiv.2105.08811", "publisher": "arXiv", "publication_date": "2021-05-18" } ]
