Angular Spectra for non-Gaussian Isotropic Fields [PDF]

open access: yes, 2013
Cosmic Microwave Background (CMB) Anisotropies is a subject of intensive research in several fields of sciences. In this paper we start a systematic development of basic notions and theory in statistics according to the application for CMB.

Enhanced Seismic Backscattering for Lava Tube Detection

open access: yesGeophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Lava tubes, a common volcanic feature on terrestrial planets, offer critical insights into lava flow processes and may serve as future potential habitats for space crews and other facilities on the Moon and Mars. Seismic detection of these features is challenging as the irregular morphology and rough cave ceilings and walls generate complex ...

Time‐Resolved Leader Spectra of Downward Terrestrial Gamma‐Ray Flashes Observed at the Telescope Array Surface Detector

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 16, 28 August 2025.
Abstract The first time‐resolved leader spectra associated with a downward Terrestrial Gamma‐ray Flash (TGF) observed by the Telescope Array Surface Detector (TASD) were recently reported by Kieu et al. (2024, https://doi.org/10.1029/2024JD041720). Building on that study, this paper presents the time‐resolved leader spectra of two additional downward ...

Exploring the Components of Cosmogenic UHECR, Neutrino, and Diffuse Gamma Ray from High-Energy Astrophysical Objects

open access: yesGalaxies
The development of multimessenger astrophysics allows us to probe various background particles from the distant early universe. Up to now, much effort has been made researching the emission and radiation of diverse steady or transient astrophysical ...

A Measurement of the Largest-scale CMB E-mode Polarization with CLASS

open access: yesThe Astrophysical Journal
We present measurements of large-scale cosmic microwave background E -mode polarization from the Cosmology Large Angular Scale Surveyor 90 GHz data. Using 115 det-yr of observations collected through 2024 with a variable-delay polarization modulator, we ...

Refitting Cosmological Data with Neutrino Mass and Degeneracy

open access: yesThe Astrophysical Journal Letters
A simple and natural extension of the standard Lambda cold dark matter (ΛCDM) model is to allow relic neutrinos to have finite chemical potentials. We confront this ΛCDM ξ model, a ΛCDM with neutrino mass M _ν and degeneracy ξ _3 as additional parameters,
