Deep Earth imaging through neutrino and seismic tomography
Sanjib Kumar Agarwalla, Arjun Datta, Amol Dighe +2
This article is a report on the Deep Earth Neutrino + Seismic Imaging and TomographY (DENSITY 2026) mini-workshop, held on 23--24 February 2026 in the Department of Earth and Clima…
Constraining the core radius and density jumps inside Earth using atmospheric neutrino oscillations
Anuj Kumar Upadhyay, Anil Kumar, Sanjib Kumar Agarwalla +1
Atmospheric neutrinos probe the interior of Earth using weak interactions, and provide information complementary to that of gravitational and seismic measurements. While passing th…
Establishing Earth's Matter Effect in Atmospheric Neutrino Oscillations at IceCube DeepCore
Anuj Kumar Upadhyay
The discovery of the non-zero value of has opened an exciting opportunity to probe the Earth's matter effects in three-flavor oscillations of atmospheric neutrinos. These…
Constraints on the Population of Common Sources of Gravitational Waves and High-Energy Neutrinos with IceCube During the Third Observing Run of the LIGO and Virgo Detectors
DoÄa Veske, Zsuzsa Márka, Albert Zhang
The discovery of joint sources of high-energy neutrinos and gravitational waves has been a primary target for the LIGO, Virgo, KAGRA, and IceCube observatories. The joint detection…
Towards the Composition of sub-PeV Cosmic Rays at IceCube
Julian Saffer
With the implementation of a low-energy trigger, the surface array of the IceCube Neutrino Observatory is able to record cosmic-ray induced air showers with a primary energy of a f…
Demonstrating the ability of IceCube DeepCore to probe Earth's interior with atmospheric neutrino oscillations
Sharmistha Chattopadhyay, Krishnamoorthi J, Anuj Kumar Upadhyay
The IceCube Neutrino Observatory is an optical Cherenkov detector instrumenting one cubic kilometer of ice at the South Pole. The Cherenkov photons emitted following a neutrino int…
