Only one supernova neutrino burst has ever been detected, and the detection of additional neutrinos from galactic core-collapse supernovae are expected to provide insight on the supernova explosion mechanism. One candidate for detecting supernova neutrinos is SNO+, a multipurpose ultra-low background particle detector. Within SNO+, a galactic supernova neutrino burst is expected to generate an...
The Helium and Lead Observatory 1 Kiloton (HALO- 1kT) is a lead-based detector to study electron neutrinos emitted in supernova events. It is proposed to follow the same-purpose lesser sensitive HALO detector located at SNOLAB, Ontario, Canada. The sensitive to electron neutrinos make HALO-1kT (and also the current HALO detector)) unique in the sense that all other detectors with capability to...
The LIGO and Virgo gravitational-wave (GW) detectors confidently detected eleven GW signals during their first two observing runs, from 2015 to 2017. Ten of these were binary black hole mergers, with total system masses ranging from about 18 to 85 solar masses. The remaining event was the spectacular binary neutron star merger GW170817, which was accompanied by a short-hard gamma-ray burst, a...
A new era of multi-messenger astronomy has arrived with the detection of
gravitational waves and high-energy astrophysical neutrinos. The successful
coordination of near real-time follow-up campaigns by multi-wavelength and
multi-messenger instruments of those events have largely extended our
understanding of the most violent phenomena in the Universe. The Jiangmen
Underground Neutrino...
Detectors around the world are poised to measure the neutrino flux from the next galactic core-collapse supernova in unprecedented detail and to shed light on the hitherto poorly-understood dynamics involved in these explosions, and on the nature of the neutrinos themselves. The utility of such an observation is enhanced as the diversity of detectors and neutrino flavor sensitivity increases....
Coherent elastic neutrino-nucleus scattering (CEvNS) is a neutral-current process in which a neutrino scatters off an entire nucleus, depositing a tiny recoil energy. The process is important in core-collapse supernovae and also presents an opportunity for detection of a burst of core-collapse supernova neutrinos in low-threshold detectors designed for dark matter detection. This talk will...
In the late stages of nuclear burning for massive stars, the pair production of neutrinos from positron-electron annihilation becomes a significant source of neutrino flux and therefore cooling. As the star evolves, the energy of these neutrinos increases and in the days preceding the supernova a significant fraction exceed the threshold for inverse beta decay. This is the golden channel for...
Predictions of the irregularity in the 11 year heartbeat of the sun due to asynchronous of the two layered dynamo effect would result in mini ice age as in the Maunder minimum. The onset of this event is expected in the beginning of 25th solar cycle and would go to its maximum in the 26th solar cycle . The minimum temperature is expected in 2028 due to the fall of solar activity by 60 % termed...
The XENONnT experiment, which is projected to begin operation by early 2020 at the Laboratori Nazionali del Gran Sasso (LNGS), is a double-phase Time Projection Chamber with a 6 tonne liquid xenon target. Although primarily developed to detect Weakly Interactive Massive Particles (WIMPs) that scatter of xenon nuclei, the detector will also be sensitive to neutrinos coming from a supernova...
The nEXO experiment is a proposed neutrino-less double beta decay (0$\nu\beta\beta$) search in the isotope Xe-136 anticipated to be located at SNOLAB. nEXO’s stringent low-background requirements necessitate a water shield in order to reduce contributions from external radiation. Photomultiplier tubes inside the water will also measure Cherenkov light of passing muons; this active shield is...
One of the possible scenarios of the multimessenger astronomical studies is the joint search for gravitational wave and low energy neutrino signals from core-collapse supernovae. This activity is pushing forward by the intercollaboration community called the GWNU group. The network includes six neutrino detectors and three gravitational wave observatories. The research is based on two...
In addition to core-collapse, a burst of neutrinos is also expected from the other two kinds of supernovae: Type Ia supernovae (SN-Iae) and pair-instability supernoave (PISNe). The leading hypothesis is that SN-Iae are the thermonuclear explosion of a carbon-oxygen white dwarf but the exact explosion mechanism is still a matter of debate. Pair-instability supernovae are the explosions of very...
The Borexino experiment has been a member of the SNEWS group since 2009. Originally the Supernova Alarm System of the detector consisted of two modules (so-called supernova monitors) which allowed to register neutrino and antineutrino event bursts from the supernova explosion. Both monitors operated in the counting mode with the alarm rate of less than one in 10 days. No information about...
With the advent of modern neutrino and gravitational wave detectors, the promise of multi-messenger detections of the next galactic core-collapse supernova has become a certainty. These detections will give insight into more than just the core-collapse supernova mechanism: they may resolve longstanding questions about the structure of the progenitor star and fundamental neutrino physics. ...
NOvA experiment uses two segmented liquid scintillator detectors, designed to study neutrino oscillations in 2 GeV neutrino beam. However, these detectors can be used to detect neutrinos from the core collapse supernova. NOvA far detector is sensitive to the SN up to 12 kpc distance with false alarm rate of 1/week. However, using the combination of signal significance from two detectors, the...
Coherent Elastic Neutrino Nucleus Scattering in direct dark matter experiments for supernova neutrino detection.
The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment under construction in China, designed with a 20 kton liquid scintillator detector. For the next galactic core-collapse supernova (SN), JUNO is promising to register full flavors of SN burst neutrinos with quite high statistics and a low energy threshold down to 0.2 MeV. A SN trigger system with the...
One of the primary physics goals of the Deep Underground Neutrino Experiment (DUNE) is measuring the electron neutrino flux from a core-collapse supernova or black hole formation. If a neutrino burst were detected, an essential piece of information would be its source location, which would be shared via the Supernova Early Warning System (SNEWS). This would allow other astronomers to observe...
The IceCube Neutrino Observatory is an anchor of the SuperNova Early Warning System (SNEWS). IceCube is comprised of 5160 digital optical modules (DOMs) instrumenting 1 km$^3$ of ice deep below the surface of the geographic South Pole. This large volume makes it sensitive to neutrinos generated by core-collapse supernovae (CCSNe) in the Milky Way at >10$\sigma$ for all progenitor models, and...
[arXiv:1802.02577] Modern neutrino facilities will be able to detect a large number of neutrinos from the next Galactic supernova. We investigate the viability of the triangulation method to locate a core-collapse supernova by employing the neutrino arrival time differences at various detectors. We perform detailed numerical fits in order to determine the uncertainties of these time...
The next Galactic core-collapse supernova is a highly anticipated event. Even prior to collapse, massive dying stars shine copiously in 'pre-supernova' (pre-SN) neutrinos, which can potentially act as efficient SN warning alarms and provide novel information about the very last stages of stellar evolution. We explore the sensitivity to pre-SN neutrinos of large direct dark matter detection...
The next observation of MeV neutrinos from a Core Collapse Supernova (CCSN) will provide important new probes on the physical mechanism driving these extreme phenomena of the Universe. The KM3NeT neutrino telescopes deployed in the Mediterranean Sea, with the multi-PMT optical module technology and a large instrumented volume, will be able to detect neutrinos from a Galactic CCSN as an overall...
Neutrinos from supernovae (SNe) are crucial probes of explosive phenomena at the deaths of massive stars and neutrino physics and high-energy neutrinos are produced through hadronic processes by cosmic rays. We point out that IceCube and KM3Net can detect about 100-1000 events from a SN II-P (and >100,000 events from a SN IIn) at a distance of 10 kpc. We provide new quantitative predictions of...
A prompt warning of supernova burst neutrino signals is quite attractive. The Daya Bay Reactor Neutrino Experiment, with liquid scintillator, is sensitive to the inverse-beta-decay (IBD) process of electron-antineutrinos, and it can give a real-time measurement of the full supernova burst neutrino energy spectrum. The Daya Bay experiment has 8 isolated neutrino detectors, so that the...
The KM3NeT collaboration has started to build the ARCA and ORCA neutrino detectors in the Mediterranean Sea. With the most recent data from the first instrumented lines deployed at each site, a detailed characterization of the detector and background has been achieved. The technique for Core-Collapse Supernova neutrino detection and its implementation as a real time trigger have been refined...
MicroBooNE is a liquid argon time projection chamber (LArTPC) in the Booster neutrino beamline at Fermilab. In addition to the beam-related physics program, MicroBooNE features a dedicated readout for detection of core-collapse supernova neutrinos and associated R&D. Being a near-surface detector exposed to an intense cosmic ray flux, MicroBooNE does not attempt to self-trigger on the...
Pre-supernova (pre-SN) neutrinos are emitted from a core of massive stars, which are supposed to be progenitors of core-collapse supernovae. Although it was seemed to be difficult to detect pre-SN neutrinos because of their low energy, detection of pre-SN neutrinos comes into view owing to the recent development of detectors. We believe that future detection of pre-SN neutrinos will give us a...
