"Building massive galaxies: Hierarchical assembly from panoramic surveys and the coming era of integral field spectroscopy"
The physical processes that regulate the growth of massive galaxies remain poorly understood.
Globally, it is expected that such galaxies assemble at late times, but this basic prediction of
hierarchical models is largely untested because cosmic variance in the small volumes sampled by
current high-z surveys swamps any potential signal. Thankfully, an array of next-generation
panoramic surveys will bring definitive answers. I will discuss early results from measurements of
galaxy assembly with one such survey, the now 50% complete Baryon Oscillation Spectroscopic
Survey (BOSS). Turning from surveys limited to only the integrated properties of distant galaxies,
I will then discuss new observational efforts in the coming era of IFU spectroscopic surveys.
I will introduce a proposed extension of the SDSS called MaNGA that, if approved, would provide
2D measures of kinematics, emission line diagnostics, and absorption line probes for 10,000
nearby galaxies. Surveys like MaNGA will test specific mechanisms that may be driving the growth
and evolution revealed in wide-field redshift surveys.

Kenneth C. Chambers (Institute for Astronomy, University of Hawaii)
"Pan-STARRS1 - Status and Early Science"
Pan-STARRS1 began the PS1 Science Mission May 13, 2009.
Operations of the PS1 System include the Observatory, Telescope,
1.4 Gigapixel Camera, Image Processing Pipeline , PSPS relational
database and reduced science product software servers.
The PS1 Surveys include: (1) A 3pi Steradian Survey;
which current has obtained more than 30 epochs in 5 passbands (grizy)
of the entire sky north of Dec = -30, or 30,000 square degrees
with 0.26 arcsecond pixels, or nearly 2 Petabytes of images;
(2) A Medium Deep survey of 10 PS1 footprints spaced around
the sky or a total of 70 square degrees; (3) A solar system ecliptic
plane survey optimized for the discovery of Near Earth Objects and
Kuiper Belt Objects, (4) a Stellar Transit Survey of ~50 square degrees in
the galactic buldge; and (5) a Deep Survey of M31 with special attention
to a proper cadence for microlensing.
The performance of the PS1 system, sky coverage, cadence, and
data quality of the images, the photometric calibration, and astrometric
precision will be presented. Early science ranging from the solar system,
brown dwarfs, galactic structure, supernovae, and galaxy counts will be
presented. The completion of the PS1 Survey, the status of PS2 and
plans for a PS1+PS2 Mission will be briefly addressed.
The PS1 Science Consortium consists of The Institute for Astronomy
at the University of Hawai'i in Manoa, the Max Planck Institute for Astronomy,
Heidelberg, the Max Planck Institute for Extraterrestrial Physics, Garching,
The Johns Hopkins University, the University of Durham, the University of
Edinburgh, the Queen's University Belfast, the Harvard-Smithsonian Center
for Astrophysics, the Los Cumbres Observatory Global Telescope Network
Incorporated, the National Central University of Taiwan, and NASA through
the NEOO program.
