Low-Energy Neutrinos (solar, reactor, supernova, and geo neutrinos and also nuclear astrophysics associated with these sources)
Oral
The IceCube Neutrino Observatory, located at South Pole Station Antarctica, is currently the world's largest neutrino telescope with an instrumented volume greater than 1 GT. Completed in December 2010, the detector's high energy neutrino program was augmented with the low-energy DeepCore extension that provides a neutrino energy threshold near 10 GeV. DeepCore has established a rich...

A search for Supernova Relic neutrinos in the energy range 13.3 MeV $<
E_{\bar{\nu}_e} <$ 31.3 MeV with neutron tagging at
Super-Kamiokande-IV is conducted. We identify
13 inverse-beta-decay candidates, all of which can be attributed to
background. In the absence of signal, 90\% C.L. upper
limits are calculated with respect to different models. A differential
flux upper limit is also...

"Supernova explosion is a phenomena which occurs in the late phase of stellar evolution. In this explosion, most of the gravitational energy released in a core collapse is carried by the neutrinos. Such neutrino bursts carry about ≈ 2.5 x 1053 ergs of energy in a very short period of time [1]. It is considered that these neutrinos provide valuable information about the proto-neutron star core,...

In the delayed explosion scenario of a core-collapse supernova (SN), the accretion phase shows pronounced convective overturns and a low-multipole hydrodynamic instability, the standing accretion shock instability (SASI). Neutrino signal variations from new three-dimensional hydrodynamical simulations of the Garching SN group as well as its detection perspectives in IceCube will be discussed....

The neutrinos which have been released from all past supernova explosions are called supernova relic neutrinos (SRN). While Super-Kamiokande has not yet observed the SRN, it has set the world's best upper limit on the flux. This limit is within a factor of 2-3 of the theoretical SRN flux predictions. GADZOOKS! is proposed as a upgrade project for Super-Kamiokande with gadolinium-loaded water....
