The Detectability of Earth's Biosignatures Across Time
Over the past two decades, enormous advances in the detection of exoplanets have taken place. Currently, we have discovered hundreds of Earth-sized planets...
The detection of supergalactic winds: The edge-on starburst galaxy NGC 4631
We are studying a sample of spiral galaxies which host nuclear starbursts. Our aim is first to detect supergalactic winds (SGWs) and second to establish the...
The detection of the 18.7 micrometer /SIII/ line in M42
The importance of forbidden line radiation is considered, taking into account lines in the visible and the infrared range. The result of a theoretical study...
The Development of Stellar Photometric Standards for ISO.
The ISO ground-based preparatory programme working group (ISO-GBPPwg) was set the goal in 1990 to characterise accurately in the infrared some 400 stars...
An investigation of the diffuse ionized gas (DIG) and its underlying physical processes is the focal point of this study. We aim to survey the prevalence...
The Disappearing Act of KH 15D: Photometric Results from the 2002-2004 Observing Campaigns
We present the results from the 2002-2004 seasons of photometric monitoring of the eclipsing system KH 15D. The eclipse has continued to evolve in secular...
