Stellar Mass and Star Formation Rate within a Billion Light-Years
  To develop galaxy-targeting approaches, the gravitational-wave community
built a catalog of stellar mass in the local universe based on the 2MASS
spectroscopic and photometric redshift surveys. By cleaning and supplementing
this catalog, the present work aims to establish a near-infrared flux-limited
sample to map both stellar mass and star formation rate (SFR) over the full
sky. The 2MASS spectroscopic and photometric redshift surveys are cross-matched
with the HyperLEDA database and the Local Volume sample at d < 11 Mpc,
providing a flux-limited sample with revised distance estimates and corrections
for incompleteness out to 350 Mpc. Scaling relations with stellar mass as a
function of morphology are used to construct a SFR cosmography in the local
universe. Stellar mass and SFR densities converge towards values compatible
with deep-field observations beyond 100 Mpc. The 3D distribution of these two
tracers is consistent with the distribution of matter deduced from cosmic
flows. With spectroscopic redshifts available for about half of the ~400,000
galaxies within 350 Mpc and photometric distances with a 12% uncertainty
available for the other half, the present sample may find applications in both
cosmology and astroparticle physics. The present work provides in particular
new bases for modeling the large- and intermediate-scale anisotropies observed
at ultra-high energies. The distribution of magnetic fields at Mpc scales,
which can be deduced from the 3D distribution of matter, is inferred to be
crucial in shaping the ultra-high-energy sky.
