APF - The Lick Observatory Automated Planet Finder
Steven S. Vogt, Matthew Radovan, Robert Kibrick +45
The Automated Planet Finder (APF) is a facility purpose-built for the discovery and characterization of extrasolar planets through high-cadence Doppler velocimetry of the reflex ba…
Extented ionized gas emission and kinematics of the compact group galaxies in HCG 16: Signatures of mergers
Claudia Mendes de Oliveira, Henri Plana, Philippe Amram +2
We report on kinematic observations of Ha emission line from four late-type galaxies of Hickson Compact Group 16 (H16a,b,c and d) obtained with a scanning Fabry-Perot interferomete…
A Merger Origin for X-Structures in S0 Galaxies
Chris Mihos, Ian Walker, Lars Hernquist +2
Using numerical simulation, we study the response of a disk galaxy to a merger involving a low-mass satellite companion. During a prograde satellite accretion, the disk galaxy form…
Towards a Precise Measurement of Matter Clustering: Lyman-alpha Forest Data at Redshifts 2-4
Rupert A. C. Croft, David H. Weinberg, Mike Bolte +5
We measure the filling factor, correlation function, and power spectrum of transmitted flux in a large sample of Lya forest spectra, comprised of 30 Keck HIRES spectra and 23 Keck…
