Cold Dust in Hot Regions
Gopika Sreenilayam, Michel Fich, Peter Ade +12
We mapped five massive star forming regions with the SCUBA-2 camera on the James Clerk Maxwell Telescope (JCMT). Temperature and column density maps are obtained from the SCUBA-2 4…
The Atlas3D project -- XXVII. Cold Gas and the Colours and Ages of Early-type Galaxies
L. M. Young, N. Scott, P. Serra +22
We present a study of the cold gas contents of the Atlas3D early-type galaxies, in the context of their optical colours, near-UV colours, and Hβ absorption line strengths. Early-ty…
Discovery of the Fomalhaut C debris disc
G. M. Kennedy, M. C. Wyatt, P. Kalas +5
Fomalhaut is one of the most interesting and well studied nearby stars, hosting at least one planet, a spectacular debris ring, and two distant low-mass stellar companions (TW PsA…
Oscillator tunneling dynamics in the Rabi model
E. K. Irish, J. Gea-Banacloche
The familiar Rabi model, comprising a two-level system coupled to a quantum harmonic oscillator, continues to produce rich and surprising physics when the coupling strength becomes…
Few-cycle fiber pulse compression and evolution of negative resonant radiation
Joanna McLenaghan, Friedrich König
We present numerical simulations and experimental observations of the spectral expansion of fs-pulses compressing in optical fibers. Using the input pulse frequency chirp we are ab…
How to pick a random integer matrix? (and other questions)
Igor Rivin
We discuss the question of how to pick a matrix uniformly (in an appropriate sense) at random from groups big and small. We give algorithms in some cases, and indicate interesting…
