‘We secured the tussac’: Accounts of ecological discovery, exploitation and renewal in the Falkland Islands

People and Nature, Volume 1, Issue 4, Page 548-561, December 2019., 2019
Abstract Sheep farms dominate the Falkland Islands landscape and have for over a century. The introduction of sheep, and several other species, has significantly transformed the ecology of this archipelago—the near elimination of tussac grass being one of the most notable changes.

Geometrodynamical Distances to the Galaxy's Hydrogen Streams

, 2007
We present a geometrodynamical method for determining distances to orbital streams of HI gas in the Galaxy. The method makes use of our offset from the Galactic centre and assumes that the gas comprising the stream nearly follows a planar orbit about the

THE COS/UVES ABSORPTION SURVEY OF THE MAGELLANIC STREAM. I. ONE-TENTH SOLAR ABUNDANCES ALONG THE BODY OF THE STREAM [PDF]

, 2013
The Magellanic Stream (MS) is a massive and extended tail of multi-phase gas stripped out of the Magellanic Clouds and interacting with the Galactic halo.

The Natural Science Underlying Big History

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
Nature’s many varied complex systems—including galaxies, stars, planets, life, and society—are islands of order within the increasingly disordered Universe. All organized systems are subject to physical, biological, or cultural evolution, which together comprise the grander interdisciplinary subject of cosmic evolution.

HIPASS High-Velocity Clouds: Properties of the Compact and Extended Populations [PDF]

, 2001
A catalog of Southern anomalous-velocity HI clouds at Decl. < +2 deg is presented, based on data from the HI Parkes All-Sky Survey (HIPASS). The improved sensitivity (5sigma: T_B = 0.04 K) and resolution (15.5') of the HIPASS data results in a ...

Current Direct Neutrino Mass Experiments

Advances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
In this contribution, we review the status and perspectives of direct neutrino mass experiments, which investigate the kinematics of β‐decays of specific isotopes (3H, 187Re, 163Ho) to derive model‐independent information on the averaged electron (anti)neutrino mass. After discussing the kinematics of β‐decay and the determination of the neutrino mass,

Properties of the Magellanic Corona

The Astrophysical Journal
We characterize the Magellanic Corona, the warm gaseous halo around the Large Magellanic Cloud (LMC). The Corona is a key ingredient in the formation of the Magellanic Stream and has recently been observed in high-ion absorption around the LMC.

Rotation of the Milky Way and the formation of the Magellanic Stream

, 2010
We studied the impact of the revisited values for the LSR circular velocity of the Milky Way (Reid et al. 2004) on the formation of the Magellanic Stream.

FOSSIL IMPRINT OF A POWERFUL FLARE AT THE GALACTIC CENTER ALONG THE MAGELLANIC STREAM [PDF]

, 2013
The Fermi satellite discovery of the gamma-ray emitting bubbles extending 50° (10 kpc) from the Galactic center has revitalized earlier claims that our Galaxy has undergone an explosive episode in the recent past.
