Machine Learning for Exploring Data Streams: Lessons from the VLBA

Next-generation science instruments such as the SKA, LSST, and terrestrial sensor networks will dramatically increase the volume of collected data.  This enables detection of very rare transient anomalies, but also creates new challenges since comprehensive storage is impossible and analysis must occur in real time.

The Search for New Particles at the CERN Large Hadron Collider

The Large Hadron Collider at CERN in Geneva, Switzerland, has begun its study of physics at distances 10,000 times smaller than an atomic nucleus. This accelerator and its experiments are enormous in many respects---in the physical size of the facilites, in the sizes of the experimental teams, but also in the stakes for our understanding of elementary particles, mass, and the universe.

Companions to solar-type stars: analysis of a wide variety of planets, brown dwarfs and small stars

Although they are relatively frequent as free-floating objects, brown dwarfs are scarcely found as companions to solar-type stars. The paucity of brown dwarfs in close-orbits first noticed by radial velocity surveys has led to the concept of the "brown dwarf desert".

How to publish a paper in Nature

Nature is one of the world's leading scientific journals, publishing many papers thatreceive wide attention by the general public. But, Nature is very selective-- <7% of submittedpapers are published. In order to maximize your chances of getting published, papers should present fundamental new physical insights, or startling observations/results.

Gravitational wave astronomy: a peek through the window

The direct detection of gravitational waves will offer a completely new window onto our Universe: one that is dominated by degenerate objects, black holes, explosions and mergers. Although this window is so far still obscured a glimpse of its richness can be seen from electromagnetic observations of gravitational wave sources. Dr. Groot will overview the progress in the fields of ultracompact binaries and the promise and results of synoptic surveys such the Kepler observations and the Palomar Transient Surveys. As an aside, and to connect to the SETI mission, Dr.

Gravity Probe B: The Relativity Gyroscope Experiment

Gravity Probe B, launched 20 April 2004, is a space experiment testing two predictions of Einstein’s theory of General Relativity, the geodetic and frame-dragging effects by means of cryogenic gyroscopes in Earth orbit.On-orbit data collection started August 2004 and ended September 2005.Analysis of the data from all four gyroscope results in a geodetic drift rate of -6,602 ±18 mas/yr and a frame-dragging rate of -37 ±7 mas/yr, to be compared with the GR predications of -6,606 mas/yr and -39 mas/yr, respectively.

Laser Plasma Spectrochemistry

Laser ablation (LA) with optical (LIBS) or mass (ICP-MS) detection is an excellent technology for direct sample (solid, liquid, gas) analysis. Benefits of laser ablation include no sample preparation, no consumables, every sample, real-time analysis, standoff (LIBS) measurements, and more. Knowledge of ablation processes, reliable system components, and development of methods has led to excellent performance metrics (accuracy and precision) of this technology.

Tools for Probing the Universe: from the Smallest to Largest and All Scales In Between

 Jeff Scargle will describe non-standard data analysis methods for extracting scientific information from time series and other data. Examples include large scale structure in the distribution of galaxies, detection of extrasolar planets, "meta-analysis" of clinical studies and psychic phenomena, variability of Fermi Gamma Ray Space Telescope sources, and the search for quantum gravity effects at the smallest possible space-time scales.

Exploratory data analysis of planetary hyperspectral datasets - use of statistics to enhance mission science return

Mario Parente will describe the latest developments in statistical
analysis of hyperspectral images, describing his efforts to enhance the
science return of the CRISM infrared spectrometer using a multi-stage
denoising technique. He will describe how it is possible to model the
CRISM instrument and efforts currently ongoing that involve
investigations of surface minerals at Juventae Chasma and Mawrth Valles
on the surface of Mars.

Viewpoints: a Fast, Interactive, Multi-platform Visualization Tool for Exploring Large Multivariate Data Sets

Finding effective ways to visualize of large multivariate data sets has become a significant challenge as data volumes have grown. Modern astrophysical data sets can easily exceed millions of samples that involve hundreds or thousands of variables. While it may be possible to plot subsets of these data using scripted languages sch as MATLAB or IDL, this presupposes that one already knows what one wishes to plot. This is rarely the case during the initial phases of data exploration.
