Narrative Self‐Transcendence: Decreased Regret and Increased Acceptance Over Late Midlife

open access: yesJournal of Personality, EarlyView.
ABSTRACT Introduction Self‐transcendence—connectedness within and beyond the self—is a complex phenomenon theorized to increase with age, but evidence is mixed. This longitudinal study is the first to investigate changes in self‐transcendence across late midlife using life story narratives.

An overview of the petrography and petrology of particles from aggregate sample from asteroid Bennu

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The OSIRIS‐REx mission returned a sample of regolith from the carbonaceous asteroid Bennu in September 2023. We present preliminary in situ investigations of the petrology and petrography of selected particles ranging in size from 0.5 to 3 mm.

Galactic cosmic ray propagation models using Picard [PDF]

open access: yesarXiv, 2015
We present results obtained from our newly developed Galactic cosmic-ray transport code PICARD, that solves the cosmic-ray transport equation. This code allows for the computation of cosmic-ray spectra and the resulting gamma-ray emission. Relying on contemporary numerical solvers allows for efficient computation of models with deca-parsec resolution ...

Testing Fundamental Physics with High-Energy Cosmic Rays [PDF]

open access: yesNuovo Cim.C24:483-496,2001, 2000
Cosmic rays may provide opportunities for probing fundamental physics. For example, ultra-high-energy cosmic rays might originate from the decays of metastable heavy particles, and astrophysical gamma rays can be used to test models of quantum gravity. Both scenarios offer ways to avoid the GZK cut-off.

Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.
