Abstract:
The Two Micron All-Sky Survey (2MASS) Redshift Survey was started two
decades ago with the goal of mapping the three-dimensional
distribution of an all-sky flux-limited (Ks<11.75mag) sample of ∼45000
galaxies. Our first data release 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 "Zone of Avoidance"
(|b|<10°)-an important region of the sky for studies of the
large-scale structure and cosmic flows. In this second and final data
release, we present redshifts for all 1041 2MRS galaxies that
previously lacked this information, as well as updated measurements
for 27 others.
Description:
We used the following facilities between 2012 May and 2018 September
to obtain 1023 redshifts:
1. The Tillinghast 1.5m telescope at the Fred L. Whipple Observatory
(FLWO) with the FAst Spectrograph for the Tillinghast (FAST).
2. The Radcliffe 1.9m telescope at the South African Astronomical
Observatory (SAAO) with the CassSpec and Spectrograph Upgrade: Newly
Improved Cassegrain (SpUpNIC) spectrographs
3. The Jorge Sahade 2.2m telescope at the Complejo Astronomico El
Leoncito (CASLEO) with the REOSC spectrograph
4. The Southern Astrophysical Research (SOAR) 4.1m telescope at the
Cerro Tololo Interamerican Observatory with the Goodman spectrograph
5. The Hiltner 2.4m telescope at the Michigan-Dartmouth-MIT (MDM)
Observatory with the Ohio State Multi-Object Spectrograph (OSMOS).
