Tracing Quenching in Nearby Galaxies through Inner Surface Mass Density and Cold Gas Content

The Astrophysical Journal
The inner stellar mass surface density within 1 kpc, Σ _1 , has emerged as a suitable proxy for bulge growth and galaxy quenching. However, the dependence of cold gas content on Σ _1 has not been thoroughly explored.

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

The first results from the Herschel-HIFI mission

, 2012
This paper contains a summary of the results from the first years of observations with the HIFI instrument onboard ESA's Herschel space observatory. The paper starts by outlining the goals and possibilities of far-infrared and submillimeter astronomy ...

Climate Emergency and Different Ways to Fail? The Fermi Paradox, the Simulation Hypothesis, Agency and Hope

Journal for the Theory of Social Behaviour, Volume 55, Issue 4, December 2025.
ABSTRACT Humanity seems stuck on different ways to fail to meet the challenge posed by a declared climate emergency and manifest problems of ecological breakdown. Rather than reprise these failures, we use the Fermi Paradox and simulation hypothesis to make a simple point about agency. The argument unfolds in two sections.

C$^+$ detection of warm dark gas in diffuse clouds [PDF]

, 2010
We present the first results of the Herschel open time key program, Galactic Observations of Terahertz C$^+$ (GOT C+) survey of the [CII] fine-structure line at 1.9 THz (158 microns) using the HIFI instrument on Herschel.

Visionaries and Crackpots, Maniacs and Saints: Existential Risk and the Politics of Longtermism

Ratio, Volume 38, Issue 4, Page 268-278, December 2025.
ABSTRACT Despite advancing strong claims about our collective priorities, longtermism has received little attention in debates in political philosophy. I first provide an account of longtermism that highlights the way it departs from established work on intergenerational justice.

Metal‐Induced Tuning of Fullerene Reactivity: Application to Nucleophile Addition

ChemPhysChem, Volume 26, Issue 23, November 28, 2025.
A textbook case of how encapsulating an atom in a carbon cage can tune assembly reactivity based on partial charge distribution–exemplified by the classic nucleophilic attack. Endohedral metallofullerenes (EMFs) are a unique class of hybrid molecules formed by encapsulating metal atoms within carbon cages (fullerenes), giving rise to distinctive ...

15 yr of Interstellar Neutral Hydrogen Observed with the Interstellar Boundary Explorer

The Astrophysical Journal Supplement Series
The interactions of our heliosphere with the surrounding local interstellar medium (LISM) lead to a range of observable phenomena such as energetic neutral atoms (ENAs) from the boundary regions of the heliosphere and the influx of interstellar neutrals (

Ph2SCCO: A New Versatile CCO‐Fragment Transfer Reagent

Angewandte Chemie International Edition, Volume 64, Issue 47, November 17, 2025.
The synthesis, isolation, and full characterization of the unprecedented heterocumulene Ph2SCCO is presented. Starting from simple precursors, Ph2SCCO provides direct access to the valuable class of (bicyclic) α‐cyclopropylcarbonyl compounds. It has emerged from our reactivity studies as an excellent reagent for the CCO fragment transfer in organic ...

The Polytropic Equation of State of Interstellar Gas Clouds [PDF]

, 2000
Models are presented for the polytropic equation of state of self-gravitating, quiescent interstellar gas clouds. A detailed analysis, including chemistry, thermal balance, and radiative transfer, is performed for the physical state of the gas as a ...
