An Analysis of the AVO Science Reference Mission

by MarkusDolensky

SRM Scenarios from AVO SWG

# SRM Scenario
S1 Circumstellar disks: from pre-Main Sequence stars to stars harbouring planets
S2 Intermediate Velocity Clouds
S3 Which star will go Supernova next?
S4 Initial Mass Function within 1 kpc: from planetary to stellar masses
S5 Initial Mass Function for massive stars
S6 The contribution from low and intermediate mass stars to the interstellar medium
S7 Galaxy Formation and Evolution from z = 10 to z = 0.1
S8 Build-up of supermassive black holes

*) Above were the scenarios available at the time of writing; further ones might have been added to the AVO SRM after the ingternal deadline.

List of Tools

# Tool
T1 multi-waveband image tool
T2 best fitting
T3 SED builder from archival data
T4 positional cross matcher
T5 access to theoretical data
T6 robotic telescope interface
T7 generic source extraction

General Infrastructure (therefore out of scope of DS4)
T8 VO Portal (GUI): browser incl. footprint generator (spatial coverage), access to data reduction
T9 workflow builder & monitor

S6 T6 rapid change detection and link to schedule of robotic telescope
S6 ? line identification service to detect changes in chemistry over time
S6 ? polarimetry support
S6 T4 data pre-filtering capability prior to processing
S6 T8 column manipulation capability
S6 T4 x-match on >=10^6 sources; account for astrometric uncert., stat. reliab.
S6 T8 fusion of images and spectra in display (slit orientation, apertures)
S6 T2 morphological classification of extended sources from images
S7 T8 multi-band thumbnail generation for given object
S7 T2 surface brightness profile matching for (faint) galaxies
S7 T1 stack images in different wavelengths
S7 T3? stack spectra at different redshifts
S7 T5 compare theoretical simulations of galaxy formations with observations
S7 ? compute angular clustering for sources in given field
S7 T5 inclusion of photometric redshift codes
S8 T2 data mining tool for detecting outliers
S8 T2 object classification by comparison with known standard objects

  • A question mark ? indicates that further analysis is required to understand the impact on the envisaged tools.
  • Some of above features might have been (partially) implemented already (see study on existing tools).
