The 2MASS Redshift Survey in the Zone of Avoidance

Understand

The 2MASS Redshift Survey was started two decades ago with the goal of mapping the three-dimensional distribution of an all-sky flux-limited (Ks<11.75 mag) sample of ~45,000 galaxies.

• Our first data release (Huchra et al.
• 2012) presented an unprecedented uniform coverage for most of the celestial sphere, with redshifts for ~98% of our sample.
• However, we were missing redshifts for ~18% of the catalog entries that were located within the &#34;Zone of Avoidance&#34; (|b|<10 deg) -- an important region of the sky for studies of large-scale structure and cosmic flows.
