To develop galaxy-targeting approaches, the gravitational-wave communitybuilt a catalog of stellar mass in the local universe based on the 2MASSspectroscopic and photometric redshift surveys. By cleaning and supplementingthis catalog, the present work aims to establish a near-infrared flux-limitedsample to map both stellar mass and star formation rate (SFR) over the fullsky. The 2MASS spectroscopic and photometric redshift surveys are cross-matchedwith the HyperLEDA database and the Local Volume sample at d < 11 Mpc,providing a flux-limited sample with revised distance estimates and correctionsfor incompleteness out to 350 Mpc. Scaling relations with stellar mass as afunction of morphology are used to construct a SFR cosmography in the localuniverse. Stellar mass and SFR densities converge towards values compatiblewith deep-field observations beyond 100 Mpc. The 3D distribution of these twotracers is consistent with the distribution of matter deduced from cosmicflows. With spectroscopic redshifts available for about half of the ~400,000galaxies within 350 Mpc and photometric distances with a 12% uncertaintyavailable for the other half, the present sample may find applications in bothcosmology and astroparticle physics. The present work provides in particularnew bases for modeling the large- and intermediate-scale anisotropies observedat ultra-high energies. The distribution of magnetic fields at Mpc scales,which can be deduced from the 3D distribution of matter, is inferred to becrucial in shaping the ultra-high-energy sky.
