The Arecibo L-band Feed Array Zone of Avoidance (ALFAZOA) Shallow Survey is a blind HI survey of the extragalactic sky behind the northern Milky Way conducted with the ALFA receiver on the 305m Arecibo Radio Telescope. ALFAZOA Shallow covered 900 square degrees at full sensitivity from 30{deg} ${leq} l {leq} $75{deg} and |b|$ {leq}$ 10{deg} and an additional 460 square degrees at limited sensitivity at latitudes up to 20{deg}. It has an rms sensitivity of 5-7 mJy and a velocity resolution of 9 - 20.6 km s$^{-1}$, and detected 403 galaxies out to a recessional velocity of 12,000 km s$^{-1}$, with an angular resolution of 3.4 and a positional accuracy between 0.2 and 1.7. The survey is complete above an integrated line flux $F_{HI}$ = 2.0 Jy km s$^{-1}$ for half the survey, and above $F_{HI}$ = 2.8 Jy km s$^{-1}$ for the other half. Forty-three percent of the ALFAZOA HI detections have at least one possible optical/NIR counterpart in the literature, and an additional 16% have counterparts that only included previous HI measurements. There are fewer counterparts in regions of high extinction and for galaxies with lower HI mass. Comparing the results of the survey to the predictions of Erdogdu et al. (2006), and using their nomenclature, ALFAZOA confirms the position and extent in the ZOA of the C7, C${zeta}$, Pegasus, Corona Borealis and Delphinus structures, but not of the Cygnus void. Two new structures are identified, both connected to the C7 overdensity; one extends to 35{deg}, and the other crosses the ZOA.
The Arecibo L-band Feed Array (ALFA) is being used to conduct a low-Galactic latitude survey, to map the distribution of galaxies and large-scale structures behind the Milky Way through detection of galaxies neutral hydrogen (HI) 21-cm emission. This
A blind HI survey of the extragalactic sky behind the southern Milky Way has been conducted with the multibeam receiver on the 64-m Parkes radio telescope. The survey covers the Galactic longitude range 212 < l < 36 and Galactic latitudes |b| < 5, an
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 Te
We present the results of the northern extension of the HI Parkes Zone of Avoidance Survey, a blind HI survey utilizing the multibeam receiver on the Parkes 64-m telescope. In the two regions studied here, l=36 to 52 deg. and l=196 to 212 deg., |b|<5
The Arecibo Ultra Deep Survey (AUDS) is a blind HI survey aimed at detecting galaxies beyond the local Universe in the 21-cm emission line of neutral hydrogen (HI). The Arecibo $L$-band Feed Array (ALFA) was used to image an area of 1.35~deg$^2$ to a
