The Luminosity & Mass Function of the Trapezium Cluster: From B stars to the Deuterium Burning Limit [PDF]
, 2002 We use the results of a new, multi-epoch, multi-wavelength, near-infrared census of the Trapezium Cluster in Orion to construct and to analyze the structure of its infrared (K band) luminosity function.

The Metal-Poor IMF, Stellar Evolution, and Star Formation Histories [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractI present an introduction to three important subjects relevant to low metallicity star formation: the IMF, stellar evolution, and star formation histories. I will draw on observations from the LCID (Local Cosmology from Isolated Dwarfs) project to illustrate some of these topics.

SWMF simulation of field-aligned currents for a varying northward and duskward IMF with nonzero dipole tilt [PDF]
Annales Geophysicae, 2008 This study concentrates on the FACs distribution for the varying northward and duskward interplanetary magnetic field (IMF) conditions when the dipole tilt is nonzero. A global MHD simulation (the Space Weather Modeling Framework, SWMF) has been used

Star formation in Perseus. IV. Mass dependent evolution of dense cores [PDF]
, 2008 In our SCUBA survey of Perseus, we find that the fraction of protostellar cores increases towards higher masses and the most massive cores are all protostellar.

Irreversibility of regime shifts in the North Sea
Frontiers in Marine Science, 2022 Human impacts can induce ecosystems to cross tipping points and hence unexpected and sudden changes in ecosystem services that are difficult or impossible to reverse. The world´s oceans suffer from cumulative anthropogenic pressures like overexploitation

ZFIRE: Using H$\alpha$ equivalent widths to investigate the in situ initial mass function at z~2 [PDF]
, 2017 We use the ZFIRE survey (http://zfire.swinburne.edu.au) to investigate the high mass slope of the initial mass function (IMF) for a mass-complete (log10(M$_*$/M$_\odot$)~9.3) sample of 102 star-forming galaxies at z~2 using their H$\alpha$ equivalent ...
