On Stellar Evolution in a Neutrino Hertzsprung–Russell Diagram
The Astrophysical Journal, 2020 We explore the evolution of a select grid of solar metallicity stellar models from their pre-main-sequence phase to near their final fates in a neutrino Hertzsprung–Russell diagram, where the neutrino luminosity replaces the traditional photon luminosity.

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract Terrestrial gamma‐ray flashes (TGFs) are short bursts of intense gamma radiation associated with lightning discharges. Although thousands of TGFs have been observed from space, TGFs detected at ground level, known as downward TGFs, are still very limited, and their relationship with lightning discharge processes remains elusive. Here we report

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Neutrino masses and ordering via multimessenger astronomy [PDF]
, 2016 We define the theoretical framework and deduce the conditions under which multimessenger astronomy can provide useful information about neutrino masses and their ordering. The framework uses time differences between the arrival of neutrinos and the other

From the Dawn of Neutrino Astronomy to a New View of the Extreme Universe
Physical Review XOver the past decade, neutrino astronomy has emerged as a new window into the extreme and hidden Universe. Current-generation experiments have detected high-energy neutrinos of astrophysical origin and identified the first sources, opening the field to ...

Ultra High Energy Cosmic Rays, Z-Shower and Neutrino Astronomy by Horizontal-Upward Tau Air-Showers.
, 2003 Ultra High Cosmic Rays (UHECR) Astronomy may be correlated to a primary parental Neutrino Astronomy: indeed any far BL Lac Jet or GRB, sources of UHECR, located at cosmic edges, may send its signal, overcoming the severe GZK cut-off, by help of UHE ZeV ...

Neutrino astronomy and lepton charge
Physics Letters B, 1969 Abstract It is shown that lepton nonconservation might lead to a decrease in the number of detectable solar neutrinos at the earth surface, because of νe←νμ oscillations, similar to K o ← K o oscillations. Equations are presented describing such oscillations for the case when there exist only four neutrino states.

Neutrino Astronomy with Korean Neutrino Observatory
, 2018 Neutrino astronomy is now possible as the technology to detect neutrinos has been advancing. Current and planned neutrino-detecting facilities can be operated as a conventional telescope because they can measure the direction toward the celestial sources
