Notes for object ESO 305- G 009

6 note(s) found in NED.


1. 2002ApJS..141..429M
Re:ESO 305- G 009
ESO 305-009. Strong nuclear continuum present. A reversal in the optical
P-V curve near V_sys_ occurs at the location of this galaxy's
semi-stellar nucleus. A misalignment of 27deg between the slit placement
and the galaxy major axis may partially account for the odd shape of
the rotation curve, which on the approaching side shows a rise, then
falls to near V_sys_ before once again rising.

Re:ESO 305- G 009
This galaxy was measured by MG to have an optical diameter of 4.6'.
Longmore et al. (1982) have published the only available H I flux for
ESO 305-009 (68.0 Jy km s^-1^). In our new Nancay observations, we
measure the following fluxes: 39.2 Jy km s^-1^ (at the galaxy center);
36.1 Jy km s^-1^ (2' W); 18.4 Jy km s^-1^ (4' W); 5.6 Jy km s^-1^
(6' W); 39.0 Jy km s^-1^ (2' E); 16.3 Jy km s^-1^ (4' E); and
3.8 Jy km s^-1^ (6' E). These measurements indicate a dip or hole in
the H I in the center of this galaxy and are not consistent with a
purely Gaussian H I distribution. Our best-fit model for the H I along
the E-W direction is the sum of two Gaussians, one positioned at 2' W
of center with {sigma} = 1.0' and one positioned 2' E of center with
{sigma} = 1.3'. We estimate a total integrated H I flux of
80.6 Jy km s^-1^, indicating that the H I flux of ESO 305-009 has been
previously underestimated. As with two of the other mapped galaxies,
V_max_ occurs outside of the central pointing: W_20,center_ =
118.0 km s^-1^, while W_20,total_ = 129.8 km s^-1^, although in this
case, V_max_ may still lie within the optical galaxy.
