A feasibility assessment of micromill sampling for Rb‐Sr and Sm‐Nd geochronology of shergottites

Meteoritics &Planetary Science, EarlyView.
Abstract Accurate dating of Martian meteorites is crucial for understanding key events in the planet's evolution. However, not all Martian meteorites are amenable to dating techniques currently in use for these rocks. The priority of sample preservation precludes mineral separation methods for low‐volume specimens, whereas the less destructive in situ ...

Documenting microbial populations within the University of Alberta Meteorite Curation Facility using 16S rRNA gene sequencing: Implications for the curation of astromaterials

Meteoritics &Planetary Science, EarlyView.
Abstract Meteorites are easily contaminated at the Earth's surface by microbial activity. Here, DNA extracts from two meteorite specimens and samples from curation laboratory surfaces are analyzed with amplicon sequencing, to understand microbial communities that contaminate meteorites and that may be resident in curation facilities.

Causality and Prediction in Modern Cosmology

Journal of Philosophical Investigations, 2016
The modern cosmology is based on the observational evidences, but several philosophical principles and metaphysical prejudices play an undeniable role in it. This paper surveys some important attitudes such as causality, prediction, determinism etc.

Non‐contrastive transcendence as gift and challenge to science and religion

Modern Theology, EarlyView.
Abstract This article suggests that the nature of transcendence represents a promising topic for future engagement between revision‐minded theologians in the field of science and religion and tradition‐oriented ones. It does so by drawing on Kathryn Tanner's account of non‐contrastive transcendence within the history of Christian theology to illuminate

Cosmology and Astrophysics with Standard Sirens and Galaxy Catalogs in View of Future Gravitational Wave Observations

The Astrophysical Journal
With the growing number of gravitational wave (GW) detections and the advent of large galaxy redshift surveys, a new era in cosmology is emerging. This study explores the synergies between GWs and galaxy surveys to jointly constrain cosmological and GW ...

Kant's nutshell argument for idealism

Noûs, EarlyView.
Abstract The significance or vacuity of the statement, “Everything has just doubled in size,” attracted considerable attention last century from scientists and philosophers. Presenting his conventionalism in geometry, Poincaré insisted on the emptiness of a hypothesis that all objects have doubled in size overnight.

Revisiting the A L Lensing Anomaly in Planck 2018 Temperature Data

The Astrophysical Journal
We revisit the lensing anomaly in the Planck 2018 temperature (TT) data and examine its robustness to frequency selection and additional sky masking. Our main findings are as follows.
