Discrete Source Survey of 6 GHz OH emission from PNe & pPNe and first 6 GHz images of K 3-35
, 2010 The aim of this study is to investigate the physical properties of molecular envelopes of planetary nebulae in their earliest stages of evolution. Using the 100m telescope at Effelsberg, we have undertaken a high sensitivity discrete source survey for ...

Conference‐Based Method: Interviewing Elites at Intergovernmental Conferences
Area, EarlyView.Short Abstract Conferences have increasingly featured within geographical research as sites of knowledge production, performance and contestation. However, this article explores how intergovernmental conferences can be productive sites for geographical fieldwork through elite interviews on research topics such as climate geopolitics and disaster risk ...

Catalog of Planetary Nebulae Detected by GALEX and Corollary Optical Surveys
The Astrophysical Journal Supplement Series, 2023 Planetary nebulae (PNs) consist of an ionized envelope surrounding a hot central star (CSPN) that emits mostly at ultraviolet (UV) wavelengths. UV observations, therefore, provide important information on both the CSPN and the nebula. We have matched the

Radio emission from the massive stars in the Galactic Super Star Cluster Westerlund 1 [PDF]
, 2009 Current mass-loss rate estimates imply that main sequence winds are not sufficient to strip away the H-rich envelope to yield Wolf-Rayet (WR) stars. The rich transitional population of Westerlund 1 (Wd 1) provides an ideal laboratory to observe mass-loss

European Law Journal, EarlyView.ABSTRACT Seeing the EU roughly as a political system designed to remove the most essential political decisions from democratic control, while in a large part abiding by legal frameworks, we could speak about an opposition between technocratic legalism and democracy.

, 2013 Black hole feedback -- the strong interaction between the energy output of supermassive black holes and their surrounding environments -- is routinely invoked to explain the absence of overly luminous galaxies, the black hole vs.

What Makes Ly$\alpha$ Nebulae Glow? Mapping the Polarization of LABd05
, 2020 "Ly$\alpha$ nebulae" are giant ($\sim$100 kpc), glowing gas clouds in the distant universe. The origin of their extended Ly$\alpha$ emission remains a mystery.

An Optical Study of Stellar and Interstellar Environments of Seven Luminous and Ultraluminous X-Ray Sources [PDF]
, 2005 We have studied the stellar and interstellar environments of two luminous X-ray sources and five ultraluminous X-ray sources (ULXs) in order to gain insight into their nature.

Nebulae (emission / absorption)
Culture and Cosmos, 2012 My presentation consists of a collage on panel. Using colour laser copies of nebulae, the dual composition recombines torn pieces of several nebular images. Optically entangled from light colour patterns, the focus of each nebula resembles the opposing behaviour of absorption and emission nebula. The collages include false colour composite astronomical
