Automation and Augmentation in Theological Perspective

Modern Theology, Volume 42, Issue 3, Page 612-628, July 2026.
Abstract AI enables forms of automation that threaten unemployment and deskilling, eliminating important opportunities for the development of virtue. The concomitant loss of virtue and meaningful employment makes it a theological problem from the perspective of Catholic social teaching and theological anthropology.

The Neutral Atomic Phases of the ISM in the Galaxy

, 2002
Much of the interstellar medium in disk galaxies is in the form of neutral atomic hydrogen, H I. This gas can be in thermal equilibrium at relatively low temperatures, T < 300 K (the cold neutral medium, or CNM) or at temperatures somewhat less than 10^4 K (the warm neutral medium, or WNM).

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Simulating the ISM in Global Disk Galaxies

, 2008
Until recently, simulations that modeled entire galaxies were restricted to an isothermal or fixed 2- or 3-phase interstellar medium (ISM). This obscured the full role of the ISM in shaping the observed galactic-scale star formation relations. In particular the Kennicutt relation suggests that star formation rates depend in a simple way on global ...

Star formation and the ISM in infrared bright galaxies - SHINING

EAS Publications Series, 2011
The Herschel Key Project SHINING performs a study of the ISM in star forming and active infrared bright galaxies (starbursts, AGN, (U)LIRGs, interacting and low metallicity galaxies) at local and intermediate redshifts. Here we present some surprising and promising first results from parts of this programme, including spatially resolved PDR diagnostics,

Star Formation and the ISM in Dwarf Galaxies

, 2000
High spatial and spectral resolution observations of the atomic interstellar medium in nearby dwarf galaxies reveal evidence for warm and cold neutral gas, just like the phases in our own Galaxy. The cold or quiescent phase (about 20% of the HI in the galaxies studied, except for LGS 3) seems to be associated with star formation activity--- it may mark

Effects of massive star formation on the ISM of dwarf galaxies [PDF]

New Astronomy Reviews, 2000
We are studying star formation effects on the properties of the ISM in low metallicity environments using mid-infrared (MIR) and far-infrared (FIR) observations of starbursting dwarf galaxies taken with the Infrared Space Observatory (ISO) and the Kuiper Airborne Observatory (KAO).

The ISM of Low Surface Brightness Galaxies

, 2000
Using Monte Carlo radiative transfer techniques, we model the dust content of the edge-on low surface brightness (LSB) galaxy UGC 7321 and explore the effects of dust on its disk color gradients. Dust alone cannot explain the large radial disk color gradients observed in this galaxy and we find that a significant fraction (~50%) of the dust in UGC 7321

The Opacity of Spiral Galaxy Disks. VIII. Structure of the Cold ISM

The Astronomical Journal, 2007
The quantity of dust in a spiral disk can be estimated using the dust's typical emission or the extinction of a known source. In this paper we compare two techniques, one based on emission and one on absorption, applied to sections of 14 disk galaxies. The two measurements reflect, respectively, the average and apparent optical depth of a disk section.

Evolution of the ISM in Luminous IR Galaxies

, 2010
Molecules that trace the high-density regions of the interstellar medium may be used to evaluate the changing physical and chemical environment during the ongoing nuclear activity in (Ultra-)Luminous Infrared Galaxies. The changing ratios of the HCN(1-0), HNC(1-0), HCO+(1-0), CN(1-0) and CN(2-1), and CS(3-2) transitions were compared with the HCN(1-0 ...
