Detecting the upturn of the solar 8B neutrino spectrum with LENA [PDF]

Physics Letters B, 2014
LENA (Low Energy Neutrino Astronomy) has been proposed as a next generation 50 kt liquid scintillator detector. The large target mass allows a high precision measurement of the solar 8B neutrino spectrum, with an unprecedented energy threshold of 2 MeV ...

Testing sterile neutrino mixing with present and future solar neutrino data

European Physical Journal C: Particles and Fields, 2022
We investigate the sensitivity of solar neutrino data to mixing of sterile neutrinos with masses $$\gtrsim $$ ≳  eV. For current data, we perform a Feldman–Cousins analysis to derive a robust limit on the sterile neutrino mixing. The solar neutrino limit

The potential to probe solar neutrino physics with LiCl water solution

European Physical Journal C: Particles and Fields, 2023
A solar neutrino detector relying on the charged-current (CC) interaction of $$\nu _e$$ ν e on $$\mathrm{{}^{7}Li}$$ 7 Li is attractive. The total CC interaction cross-section weighted by the solar $$^8$$ 8 B electron neutrino spectrum is approximately ...

Advice for a Young Scientist

Perspectives of Earth and Space Scientists, Volume 4, Issue 1, December 2023., 2023
Abstract My career has included astrophysics and space physics, always with a theoretical emphasis. My first papers calculated nuclear reaction rates in dense stars, particularly neutron stars, but I branched out to other areas or theoretical astrophysics.

Muon Flux Variations Measured by Low‐Cost Portable Cosmic Ray Detectors and Their Correlation With Space Weather Activity

Journal of Geophysical Research: Space Physics, Volume 128, Issue 12, December 2023., 2023
Abstract We present a comparison of the measured cosmic ray (CR) muon fluxes from two identical portable low‐cost detectors at different geolocations and their sensitivity to space weather events in real time. The first detector is installed at Mount Wilson Observatory, CA, USA (geomagnetic cutoff rigidity Rc ∼ 4.88 GV), and the second detector is ...

Identifying the Variety of Jovian X‐Ray Auroral Structures: Tying the Morphology of X‐Ray Emissions to Associated Magnetospheric Dynamics

Journal of Geophysical Research: Space Physics, Volume 128, Issue 11, November 2023., 2023
Abstract We define the spatial clustering of X‐rays within Jupiter's northern auroral regions by classifying their distributions into “X‐ray auroral structures.” Using data from Chandra during Juno's main mission observations (24 May 2016 to 8 September 2019), we define five X‐ray structures based on their ionospheric location and calculate the ...

Investigating Sterile Neutrino Flux in the Solar Neutrino Data

Advances in High Energy Physics, 2019
There are compelling evidences for the existence of a fourth degree of freedom of neutrinos, i.e., sterile neutrino. In the recent studies the role of sterile component of neutrinos has been found to be crucial, not only in particle physics, but also in ...

Neutrino oscillation anomalies [PDF]

EPJ Web of Conferences, 2023
I give an overview of some of the several anomalies appearing in neutrino oscillation experiments, setting particular focus to the reactor antineutrino anomaly and the Gallium anomaly. I will discuss these two anomalies in some detail and, in particular,

The spectroscopy of solar sterile neutrinos

European Physical Journal C: Particles and Fields, 2018
We predict the sterile neutrino spectrum of some of the key solar nuclear reactions and discuss the possibility of these being observed by the next generation of solar neutrino experiments.

Theoretical and Experimental Challenges in the Measurement of Neutrino Mass

Advances in High Energy Physics, 2023
Neutrino masses are yet unknown. We discuss the present state of effective electron antineutrino mass from β decay experiments; effective Majorana neutrino mass from neutrinoless double-beta decay experiments; neutrino mass squared differences from ...
