Structure and Evolution of Pre-Main Sequence Stars

Kavli Affiliate: Ralf Heilmann | First 5 Authors: Norbert S. Schulz, Glenn Allen, Mark W. Bautz, Claude C. Canizares, John Davis | Summary: Low-mass pre-main sequence (PMS) stars are strong and variable X-ray emitters, as has been well established by EINSTEIN and ROSAT observatories. It was originally believed that this emission was of thermal nature […]

LSST: from Science Drivers to Reference Design and Anticipated Data Products

Kavli Affiliate: Stuart Marshall | First 5 Authors: Željko Ivezić, Steven M. Kahn, J. Anthony Tyson, Bob Abel, Emily Acosta | Summary: (Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, […]

Collisional Dark Matter and Scalar Phantoms

Kavli Affiliate: Anthony Zee | First 5 Authors: Daniel E. Holz, Anthony Zee, , , | Summary: As has been previously proposed, a minimal modification of the standard $SU(3)times SU(2)times U(1)$ theory provides a viable dark matter candidate. Such a particle, a scalar gauge singlet, is naturally self-interacting—making it of particular interest given recent developments […]
