2MASS bright galaxies HI ZoA survey
Listed in IVOA Registry (Virtual Observatory)
To complement the 2MASS Redshift Survey (2MRS) and the 2MASS Tully-Fisher survey (2MTF) a search for 21cm HI line emission of 2MASS bright galaxy candidates has been pursued along the dust-obscured plane of the Milky Way with the 100m Nancay Radio Telescope.
Description
For our sample selection we adopted an isophotal extinction-corrected K-band magnitude limit of Ks^o^=11.25mag, corresponding to the first 2MRS data release and 2MTF, for which the 2MASX completeness level remains fairly constant deep into the Zone of Avoidance (ZoA).
About one thousand galaxies without prior redshift measurement accessible from Nancay (Dec>-40deg) were observed to an rms noise level of ~3mJy for the velocity range -250 to 10600km/s. This resulted in 220 clear and 12 marginal detections of the target sample. Only few detections have redshifts above 8000km/s due to recurring radio frequency interference (RFI).

A further 29 detections and 6 marginals have their origin in non-target galaxies in the telescope beam. The newly detected galaxies are on average considerably more HI-rich (mostly 10^9^-10^10^M_{sun}_) compared to systematic (blind) HI surveys. The HI detections reveal various new filaments crossing the mostly uncharted northern ZoA (e.g., at GLON ~90deg, 130deg, 160deg), whilst consolidating galaxy agglomerations in Monoceros and Puppis (GLON ~220deg, 240deg).
Considerably new insight has been gained about the extent of the Perseus-Pisces Supercluster through the confirmation of a ridge (GLON~16deg) encompassing the 3C129 cluster that links Perseus-Pisces to Lynx, and the continuation of the second Perseus-Pisces arm (GLON~90deg) across the ZoA. A Hubble constant of H_0_=75km/s/Mpc has been used.
