  • ASTRONET IR Final Word Doc for Printing with Logo
    ASTRONET: Infrastructure Roadmap Update Ian Robson The ASTRONET Science Vision and Infrastructure Roadmap were published in 2007 and 2008 respectively and presented a strategic plan for the development of European Astronomy. A requirement was to have a light-touch update of these midway through the term. The Science Vision was updated in 2013 and the conclusions were fed into the Roadmap update. This was completed following the outcome of the ESA decisions on the latest missions. The community has been involved through a variety of processes and the final version of the update has been endorsed by the ASTRONET Executive. ASTRONET was created by a group of European funding agencies in order to establish a strategic planning mechanism for all of European astronomy . It covers the whole astronomical domain, from the Sun and Solar System to the limits of the observable Universe, and from radioastronomy to gamma-rays and particles, on the ground as well as in space; but also theory and computing, outreach, training and recruitment of the vital human resources. And, importantly, ASTRONET aims to engage all astronomical communities and relevant funding agencies on the new map of Europe. http://www.astronet-eu.org/ ASTRONET has been supported by the EC since 2005 as an ERA-NET . Despite the formidable challenges of establishing such a comprehensive plan, ASTRONET reached that goal with the publication of its Infrastructure Roadmap in November 2008. Building on this remarkable achievement, the present project will proceed to the implementation stage, a very significant new step towards the coordination and integration of European resources in the field.

The search targets low Galactic latitudes, b . 5◦, in the accessible longitude ranges, 32◦ . ℓ . 77◦ and 168◦ . ℓ . 214◦. The instrumentation, data processing,| | initial survey observations, sensitivity, and database management are described. Data discussed here were collected over a 100 MHz passband centered on 1.42 GHz using a spectrometer that recorded 256 channels every 64 µs. Analysis of the data with their full time and frequency resolutions is ongoing. Here, we report the results of a preliminary, low-resolution analysis for which the data were decimated to speed up the processing.

  • Fast and Accurate Estimation for Astrophysical Problems in Large Databases
    Fast and Accurate Estimation for Astrophysical Problems in Large Databases Joseph Richards Thesis Proposal August 18, 2009 Abstract In this proposed thesis, I will develop efficient non-parametric methods for parameter estima- tion in large databases of high-dimensional, noisy data. Specifically, I plan to continue exploring the efficacy of the diffusion map method of data transformation, used in conjunction with the Nystr¨omextension, in uncovering underlying structure in complicated, high-dimensional data sets. I will explore models that effectively exploit this structure to accurately estimate scien- tific parameters of interest. Additionally, I will formulate multi-scale methods that generate data-driven bases within local partitions to allow for the modeling of more complicated data. The proposed methods will be tested on three research problems in astrophysics: estimation of star formation history (SFH) in galaxies using spectra from the Sloan Digital Sky Survey (SDSS), photometric redshift estimation using data from the SDSS Photometric Survey and the Canada-France-Hawaii Telescope Legacy Survey, and detection of classes of quasar and outliers using SDSS spectra. Preliminary work has already shown promise in the proposed methods for both SFH estimation (Richards et al. 2009) and photometric redshift estimation (Freeman et al. 2009). 1 Astronomical survey data Technological advancements in observational astronomy have caused a recent flood of astronomical surveys that collect data from billions of objects.1 Modern surveys amass data for different

  • Astro2010: the Astronomy and Astrophysics Decadal Survey
    Astro2010: The Astronomy and Astrophysics Decadal Survey Notices of Interest 1. 4 m space telescope for terrestrial planet imaging and wide field astrophysics Point of Contact: Roger Angel, University of Arizona Summary Description: The proposed 4 m telescope combines capabilities for imaging terrestrial exoplanets and for general astrophysics without compromising either. Extremely high contrast imaging at very close inner working angle, as needed for terrestrial planet imaging, is accomplished by the powerful phase induced amplitude apodization method (PIAA) developed by Olivier Guyon. This method promises 10-10 contrast at 2.0 l/D angular separation, i.e. 50 mas for a 4 m telescope at 500 nm wavelength. The telescope primary mirror is unobscured with off-axis figure, as needed to achieve such high contrast. Despite the off-axis primary, the telescope nevertheless provides also a very wide field for general astrophysics. A 3 mirror anastigmat design by Jim Burge delivers a 6 by 24 arcminute field whose mean wavefront error of 12 nm rms, i.e.diffraction limited at 360 nm wavelength. Over the best 10 square arcminutes the rms error is 7 nm, for diffraction limited imaging at 200 nm wavelength. Any of the instruments can be fed by part or all of the field, by means of a flat steering mirror at the exit pupil. To allow for this, the field is curved with a radius equal to the distance from the exit pupil. The entire optical system fits in a 4 m diameter cylinder, 8 m long. Many have considered that only by using two spacecraft, a conventional on-axis telescope and a remote occulter, could high contrast and wide field imaging goals be reconciled.

The sky is hardly static: many interesting phenomena occur, including variable stationary objects such as stars or QSOs, transient stationary objects such as supernovae or M dwarf flares, and moving objects such as asteroids and the stars themselves. Funded by NASA, we have designed and built a sky survey system for the purpose of finding dangerous near-Earth asteroids (NEAs). This system, the \Asteroid Terrestrial-impact Last Alert System" (ATLAS), has been optimized to produce the best survey capability per unit cost, and therefore is an efficient and competitive system for finding potentially hazardous asteroids (PHAs) but also for tracking variables and finding transients. While carrying out its NASA mission, ATLAS now discovers more bright (m < 19) supernovae candidates than any ground based survey, frequently detecting very young explosions due to its 2 day cadence.
