goldmine sample

The new GOLDMine site (see Gavazzi, Franzetti & Boselli, 2014, arXiv:1401.8123) enables to visualize (and retrieve in tabular form) multifrequency data (from the UV to the centimetric radio, continuum and line, whose list can be selected with the "available data" button) by navigating (continuum panning and zooming -in and -out) the whole northern sky covered by SDSS (DR10) (Ahn et al. 2014) that is set as color- background picture. Alternatively one can choose to pan other all-sky panoramic (X-ray, UV, optical, FIR and radio) data-sets.
At any time the coordinates of the center of the visible frame are given (in degrees or in hh,mm,ss) and the width of the field of view (FOV) is indicated.

Targets can be selected by cluster, by name, by coordinates (both in degrees and in hh,mm,ss), individually (marked with a red circle) or by lists. For all targets a fast link to the SDSS (DR10) navigator and to the NED database are offered.

By switching-in the "show targets in FOV" option, all targets visible in the FOV belonging to the GOLDMine database are highlighted (white circles) and the corresponding data can be retrieved with "get data from FOV". Galaxies in the GOLDMine database satisfy the conditions (see wedge diagram in figure 1):

  • Cancer cluster 0<cz<9000 km/s
  • Local supercluster cz<3000 km/s
  • Coma supercluster 4000<cz<9500 km/s
  • A2147+2151 clusters 8000<cz<15000 km/s
  • A2197+2199 clusters 7000<cz<11000 km/s

In addition to the galaxies belonging to the proper GOLDMine database, a number of miscellaneous galaxies are visualized with blue circles. These are selected from NED with the following criteria: 10<RA<16; Dec>0; cz<10000 km/s and mag<17.7 (excluding those that already belong to GOLDMine) (see figure 2 in spherical coordinates).

On an even larger scale (the whole northern hemisphere) green circles indicate all NGC and IC galaxies with cz<10000 \rm km/s and with B<17.0 mag (excluding those already listed) (see figure 3)
