The galaxy NGC6810

ATCA Results


Project C419 + C574: ATCA 375, 750A + 1.5A arrays (beam = 63.2" x 59.7", natural weighting),
observed 20-04-1996, 14-11-1996 and 28-10-1996, re-reduced 08-05-2008.

The HI and 20-cm radio continuum results are presented in Chapter 8 of Scott Gordon's University of Queensland PhD Thesis (2002).

Neutral hydrogen is detected in the galaxy NGC 6810 (middle; v = 2031 km/s) and two companions, ESO142-G032 (SW of NGC 6810, v = 1927 km/s) and a new galaxy, ATCA J1944-58 (NE of NGC 6810, v = 2090 km/s). The HI position of ATCA J1944-58 is 19:44:53, -58:29:45.

NGC6810 is detected in HIPASS, but very faint. Its HI flux density is 9.5 Jy km/s which corresponds to an HI mass of about 1.4 x 10^9 Msun, assuming a distance of 25 Mpc. - ESO142-G032 is also detected in HIPASS. Its HI flux density is 8 Jy km/s which corresponds to MHI = 1.2 x 10^9 Msun. - ATCA J1944-58 is not detected in HIPASS. Its HI flux density is 1.2 Jy km/s which corresponds to MHI = 2 x 10^8 Msun.



IF2: wide-band 20-cm continuum (beam = 33.0" x 29.5", robust=0 weighting).
