Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Probing the star formation history of early-type galaxies in clusters [PDF]

open access: yes, 1998
In this thesis, we present a new photometric catalogue of the local Coma galaxy cluster in the Johnson U- and V- bands. We cover an area of 3360arcmin(^2) of sky, to a depth of V = 20mag in a 13 arcsec diameter aperture, and produce magnitudes for ~ 1400

Beyond No No Tension: JWST z > 10 Galaxies Push Simulations to the Limit

open access: yesThe Open Journal of Astrophysics
JWST has identified some of the Universe's earliest galaxies, repeatedly pushing the frontier to ever higher redshifts and stellar masses. The presence of such extreme galaxies at such early times, with large stellar populations and high star-formation ...

From Flow to Function: Using Different Static Mixers to Fabricate Microarchitected Materials Via Chaotic Printing

open access: yesAdvanced Science, Volume 13, Issue 55, 5 October 2026.
Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds

An investigation of the active galaxies M82 and NGC 5128 [PDF]

open access: yes, 1995
In this thesis we present multi-waveband imaging polarimetry and spectropolarime- try of the starburst galaxy M82 and multi-waveband imaging polarimetry of the active galaxy NGC 5128. A review of previous studies of these galaxies is given.
