VizieR Online Data Catalog: Compact radio sources within 30" of Sgr A* (Yusef-Zadeh+, 2015)

We obtained two sets of A-array observations with the Karl G. Jansky Very Large Array (VLA). The first set of observations of the stellar cluster at the Galactic center were obtained on 2011 July 8-9 and 2011 August 31-September 1 at 44GHz (program 11A-224). Further details of these first-epoch observations are given in Yusef-Zadeh et al. (2014ApJ...792L...1Y). We reobserved the region within 30" of Sgr A* on 2014 February 21, again using the VLA in its A-configuration at 44GHz. We also carried out A-array observations (program 14A-232) in the Ka (9mm) band on 2014 March 9 at 34.5GHz.

We searched for NIR counterparts to compact radio sources using high-angular resolution AOs assisted imaging observations acquired with the VLT/NACO (NAos-COnica). A Ks-band (central wavelength 2.18um) image was obtained in a rectangular dither pattern on 2012 September 12. L'-band (3.8um) observations were obtained during various observing runs between 2012 June and September.
