Mass Extinction And The Structure Of The Milky Way

M. D. Filipović, J. Horner, E. J. Crawford +1

We use the most up to date Milky Way model and solar orbit data in order to test the hypothesis that the Sun's galactic spiral arm crossings cause mass extinction events on Earth.…

Aligned grains and inferred toroidal magnetic fields in the envelopes of massive young stellar objects

Janet P. Simpson, Barbara A. Whitney, Dean C. Hines +6

Massive young stellar objects (YSOs), like low-mass YSOs, are thought to be surrounded by optically thick envelopes and/or discs and are observed to have associated regions that pr…

Spectral imaging of the Central Molecular Zone in multiple 7-mm molecular lines

P. A. Jones, M. G. Burton, M. R. Cunningham +2

We have imaged 24 spectral lines in the Central Molecular Zone (CMZ) around the Galactic Centre, in the range 42 to 50 GHz. The lines include emission from the CS, CH3OH, HC3N, SiO…
